Detailed Description

In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The user information to which the present disclosure relates may be information authorized by the user or sufficiently authorized by each party.

Hereinafter, terms related to the embodiments of the present disclosure are explained.

Vertical search: also called vertical search, vertical search for short. Vertical search is a product form widely existing in an APP (Application program) of a mobile terminal on a current smart phone, and indicates a search behavior for querying a certain vertical classification and a corresponding search result page thereof as indicated by a literal meaning. Illustratively, taking a short video search scene as an example, a user takes a content tag of a certain short video as a search word and initiates a vertical search, and short videos (or called works) related to the content tag, namely a vertical category, will be displayed in a result page, which is also referred to as a detail page of the vertical category or a landing page of the search behavior at this time.

Unlike the conventional search behavior, the vertical search behavior initiated by the user carries an attribute of "shopping and strolling", that is, the user may only think about what short videos related to the vertical category are but does not have an explicit search intention, so that each short video in the vertical search result page should carry a recommendation attribute. Generally, although each short video in the result page belongs to the vertical category, for example, each short video in the content vertical category on the short video platform is recalled by the vertical search algorithm after the video publisher itself hits the corresponding content tag, because there are behaviors such as "degree of smearing", that is, the video publisher hits the content tag which is not related but has high degree of popularity to the short video uploaded by itself, it is difficult to ensure whether each short video presented in the result page is really related to the vertical category.

In an exemplary scenario, an entry where a user initiates a vertical search is a short video carrying a certain content tag, for example, in the process of browsing a current short video, the user creates curiosity about the content tag carried by the short video, and when the user clicks the content tag, the user jumps to a result page of the content tag, so as to view other short videos also carrying the content tag.

In view of this, the embodiment of the present disclosure provides a resource searching method, which can introduce the characteristics of a multimedia resource (i.e., a first multimedia resource) where a user has a click behavior into a resource sorting and recall algorithm of a result page, that is, on the premise that the user is interested in the first multimedia resource, promote a second multimedia resource with a higher similarity to the first multimedia resource in the result page to increase exposure, so that the user can browse more second multimedia resources with possible interest in the result page, thereby improving the searching accuracy of each multimedia resource in a vertical search result page, and increasing the consumption and experience of the user on a vertical search behavior, where the first multimedia resource may also be referred to as a flow-through multimedia resource, a flow-through work, and the like.

Fig. 3 is an interaction flowchart illustrating a resource search method according to an exemplary embodiment, where, as shown in fig. 3, the resource search method is used in an interaction process between a terminal and a server, and the terminal and the server are exemplary illustrations of computer devices, and the embodiment includes the following steps.

In step 301, the terminal sends a search request carrying a search term to the server.

The terminal is provided with and runs with an application program supporting multimedia resources, and a user starts the application program on the terminal and can browse each multimedia resource in the application program. Optionally, the multimedia resource currently browsed by the user is referred to as a first multimedia resource, and the user may trigger generation of the search request through a content tag of the first multimedia resource in the process of browsing the first multimedia resource. Optionally, the user may also directly click the search tag in the application program, trigger and display the search input box and the search confirmation option, directly input the search word in the search input box, click the search confirmation option, and trigger and generate the search request, which is not specifically limited in the embodiment of the present application.

In some embodiments, the search request may be divided into a first search request and a second search request, depending on how the search request is triggered. The first search request is generated based on the triggering operation of the content label on the playing interface of the first multimedia resource, and the second search request is generated based on the input operation of the user in the search input box.

In some embodiments, since the first search request is generated based on a triggering operation on a content tag on a playing interface of the first multimedia resource, meaning that the first search request is formed by streaming of the first multimedia resource, the user performs the triggering operation on the content tag of the first multimedia resource in the case of browsing the first multimedia resource, and the terminal sends the first search request to the server.

In some embodiments, the terminal displays a plurality of content tags of the first multimedia resource in a playing interface of the first multimedia resource; and sending a search request carrying the content tag and the resource identifier of the first multimedia resource in response to the triggering operation of the user on any content tag in the plurality of content tags. The content tag is a search word, and the search request is a first search request.

Optionally, the triggering operation includes, but is not limited to: the touch control method includes click operation, touch operation, double-click operation, long-press operation, drag operation, voice instruction, gesture instruction and the like.

In the process, the terminal generates the search request through the triggering of the content tag of the first multimedia resource, so that the content tag is used as a search word, and the resource identifier of the first multimedia resource is directly added in the search request to represent that the content tag is associated with the first multimedia resource, thereby facilitating the server to determine the search word and the first multimedia resource and improving the calculation efficiency of the server.

In some embodiments, since the second search request is generated based on the user's input operation in the search input box, it means that the second search request is not guided by some certain determined first multimedia resource, but is triggered by a search action actively and spontaneously initiated by the user in the search input box, at which time the terminal sends the second search request to the server.

In some embodiments, the terminal displays a search tag in a main interface of an application program, a user can display a search input box and a search confirmation option in the main interface by performing a trigger operation on the search tag, then, the user can perform an input operation in the search input box and perform a trigger operation on the search confirmation option after the input is completed, the terminal obtains information input in the search input box as a search word, and sends a search request carrying the search word, where the search request is a second search request.

Optionally, the input operation includes, but is not limited to: the input method is used for manual input, the automatic speech recognition technology is used for speech input and converting the speech input into corresponding text information, and the like, and the operation mode of the input operation is not specifically limited in the embodiment of the disclosure.

In the process, the terminal triggers and generates the search request through the input operation in the search input box, so that in a scene without explicit diversion multimedia resources, the server can select the first multimedia resources according to the historical browsing records of the account of the login terminal under the condition, and each second multimedia resource can still be acquired by using the resource search mode provided by the embodiment of the disclosure, so that the accuracy of the search result is improved.

In step 302, the server determines a search word and a first multimedia resource corresponding to the search request in response to the search request, wherein the first multimedia resource is associated with the search word.

In some embodiments, the server may determine the search term and the first multimedia resource in different ways according to the type of the search request. The following discussion will be directed to the first search request and the second search request, respectively.

In some embodiments, if the search request is a first search request, the server obtains the search word and the resource identifier of the first multimedia resource from the first search request, where the first search request is generated based on a trigger operation on a content tag on a play interface of the first multimedia resource, and the first search request takes the content tag as the search word. For example, the content tag is encapsulated into a search term field in the first search request.

Optionally, the server receives the search request, analyzes a header field in the search request, determines that the search request is the first search request if the header field carries the type identifier of the first search request, and at this time, may directly analyze a search word field of the first search request to obtain the search word, analyze a resource identifier field of the first search request to obtain the resource identifier, and determine that the multimedia resource indicated by the resource identifier is the first multimedia resource.

In the process, the server can directly analyze the first search request to obtain the search terms and the resource identifier of the first multimedia resource without additional processing, so that the computing resource of the server is saved, and the computing efficiency of the server is improved.

In some embodiments, if the search request is a second search request, the search term carried by the search request is obtained, and the second search request is generated based on an input operation in a search input box; and selecting the multimedia resource associated with the search word from the historical browsing records as the first multimedia resource.

Optionally, the server receives the search request, analyzes a header field in the search request, determines that the search request is the second search request if the header field carries a type identifier of the second search request, at this time, may directly analyze a search word field of the second search request to obtain the search word, further, analyzes a user field of the second search request to obtain an account identifier of an account that logs in a terminal corresponding to the search request, then, obtains a history browsing record corresponding to the account identifier, and queries, from the history browsing record, to obtain the multimedia resource associated with the search word as the first multimedia resource.

In the process, the server can configure the corresponding first multimedia resource according to the historical browsing record of the account for the second search request even if the server does not carry a clear resource identifier to indicate the corresponding first multimedia resource, so that the universality of the resource search method provided by the embodiment of the disclosure can be improved, and the search accuracy under various scenes can be integrally improved.

In some embodiments, when the server selects the first multimedia resource from the historical browsing history, the server may select a multimedia resource whose content tag includes the search term and whose timestamp is the latest from the historical browsing history as the first multimedia resource.

Optionally, the server obtains a tag set formed by all content tags carried by all multimedia resources in the history browsing record, and queries whether any content tag is hit in the index in the tag set by using the search word as the index, and if any content tag is hit in the index, the server indicates that the search word is included in any content tag. The above process is repeatedly executed, one or more content tags hit by the index can be determined, at this time, one or more multimedia resources carrying the one or more content tags are obtained from the historical browsing record, and the multimedia resource with the latest timestamp in the one or more multimedia resources is selected as the first multimedia resource.

Optionally, the latest meaning of the timestamp may be that the timestamp of the last browsing of the corresponding multimedia resource by the account is latest, or the timestamp of the video publisher publishing the corresponding multimedia resource is latest, or the timestamp of any account in the platform reviewing the corresponding multimedia resource is latest, which is not specifically limited in this embodiment of the disclosure.

In the above process, for the case that the search term has high correlation with the content tag, the server selects, as the first multimedia resource, the multimedia resource having the content tag and the latest timestamp from the historical browsing record of the account, so as to improve the search accuracy, because when the user inputs a certain content tag in the search input box, the user usually browses the multimedia resource carrying the content tag once and curiously wants to view other similar multimedia resources, so that the first multimedia resource is determined from the historical browsing record, and information supplement can be performed for the scene missing the first multimedia resource.

In some embodiments, if all content tags are missed in the index in the above tag set, in this case, the server may select the multimedia resource with the highest similarity to the search term from the historical browsing records as the first multimedia resource.

Optionally, the server may perform the above operation of performing a matching query on the tag set based on the index, if the index can hit any content tag, select a multimedia resource with the content tag and the latest timestamp as the first multimedia resource, if the index fails to hit all content tags, further obtain a similarity between the search term and each multimedia resource in the history browsing record, and select a multimedia resource with the highest similarity as the first multimedia resource, so that a direct association between the first multimedia resource and the search term can be improved.

Optionally, the server may not perform the above operation of performing matching query on the tab set based on the index, but directly obtain the similarity between the search term and each multimedia resource in the history browsing record, and select the multimedia resource with the highest similarity as the first multimedia resource, so as to simplify the processing flow of obtaining the first multimedia resource.

In some embodiments, for each candidate multimedia resource, the server may obtain detail information for the candidate multimedia resource, which may be text formed from at least one of a title, a summary, a publisher nickname, a publisher account number, or a content tag of the candidate multimedia resource. Then, the detail information is embedded to obtain the embedded feature of the detail information, and the embedded feature of the detail information is used as the second resource feature, so that the complexity of acquiring the second resource feature can be simplified.

In some embodiments, the server may further input the detail information of the candidate multimedia resource and the key frame of the candidate multimedia resource into a feature extraction model, extract a fusion feature between the detail information and the key frame through the feature extraction model, and use the fusion feature as the second resource feature, so as to improve the expressive ability of the second resource feature. Optionally, the key frame may be a cover page of the candidate multimedia resource, or may be one or more key video frames of the candidate multimedia resource, where the key video frames may be set by a video publisher, or may be intelligently identified and extracted by a server, and the embodiment of the present disclosure is not specifically limited to this.

In some embodiments, after the search term feature, the first resource feature, and the second resource feature of each candidate multimedia resource are extracted, fig. 4 is a flowchart of determining the second multimedia resource according to an embodiment of the disclosure, as shown in fig. 4, the server may determine each second multimedia resource through the following

steps

3041 and 3043, which are described in detail below.

In step 3041, the server determines at least one third multimedia resource from the candidate multimedia resources based on the search term feature, the first resource feature and the second resource feature of the candidate multimedia resources, wherein the similarity between the third multimedia resource and the search term and the first multimedia resource meets the first target condition.

In some embodiments, the server, in determining the respective third multimedia resource, may perform the following operations for any candidate multimedia resource of the plurality of candidate multimedia resources: acquiring a first similarity between the search term characteristic and a second resource characteristic of the candidate multimedia resource; acquiring a second similarity between the first resource characteristic and a second resource characteristic of the candidate multimedia resource; weighting the first similarity and the second similarity to obtain a third similarity; and under the condition that the third similarity meets the first target condition, determining the candidate multimedia resource as a third multimedia resource.

In some embodiments, the first similarity may be a cosine distance between the search term feature and a second resource feature of the candidate multimedia resource, an inverse euclidean distance between the search term feature and the second resource feature of the candidate multimedia resource, or other parameters for characterizing the similarity degree, such that the similarity degree between the search term and the candidate multimedia resource is higher when the first similarity degree is higher, and conversely, the similarity degree between the search term and the candidate multimedia resource is lower when the first similarity degree is lower.

In some embodiments, the second similarity may be a cosine distance between the first resource feature and a second resource feature of the candidate multimedia resource, an inverse euclidean distance between the first resource feature and the second resource feature of the candidate multimedia resource, or other parameters for representing the degree of similarity, such that the greater the second similarity, the higher the degree of similarity between the first multimedia resource and the candidate multimedia resource, and vice versa, the smaller the second similarity, the lower the degree of similarity between the first multimedia resource and the candidate multimedia resource.

In some embodiments, when obtaining the third similarity, an arithmetic mean value between the first similarity and the second similarity may be used as the third similarity, or a harmonic mean value between the first similarity and the second similarity may be used as the third similarity, or a first coefficient and a second coefficient may be obtained, a sum of the first coefficient and the second coefficient is equal to 1, the first coefficient is multiplied by the first similarity to obtain a first value, the second coefficient is multiplied by the second similarity to obtain a second value, the first value is added to the second value to obtain the third similarity, wherein the first coefficient represents a specific gravity of the first similarity in the third similarity, and the second coefficient represents a specific gravity of the second similarity in the third similarity. The first coefficient and the second coefficient are both numerical values greater than or equal to 0 and less than or equal to 1.

The server executes the above operation on each candidate multimedia resource, so as to obtain a third similarity of each candidate multimedia resource, and then selects the candidate multimedia resource with the third similarity meeting the first target condition as the third multimedia resource.

In some embodiments, in determining whether the third similarity meets the first target condition, the server may perform the following operations: ranking the plurality of candidate multimedia resources based on the order of the third similarity from large to small; if the candidate multimedia resource is located at the first target position in the ranking, the candidate multimedia resource is determined to be a third multimedia resource. Wherein the first target bit is any integer number of bits greater than or equal to 1.

In the above process, the first target position candidate multimedia resources with the largest third similarity among all the candidate multimedia resources are selected as the third multimedia resources, which is equivalent to recall the third multimedia resources related to the search term and the first multimedia resources from the massive candidate multimedia resources, so that the final second multimedia resources are determined by sequencing the third multimedia resources through the following

steps

3042 and 3043, and the search accuracy of the second multimedia resources can be improved.

In some embodiments, in determining whether the third similarity meets the first target condition, the server may perform the following operations: and if the third similarity is larger than the similarity threshold value, determining the candidate multimedia resource as a third multimedia resource. Wherein the similarity threshold is any value greater than or equal to 0.

In the process, the candidate multimedia resources with the third similarity larger than the similarity threshold value are selected from all the candidate multimedia resources as the third multimedia resources, so that the number of the third multimedia resources determined in the recall stage is not limited, the omission of some candidate multimedia resources with higher similarity degrees is avoided, and the searching accuracy of the second multimedia resources is improved.

In step 3042, the server obtains a target behavior parameter of the at least one third multimedia resource, where the target behavior parameter is used to characterize a possibility that the account performs a target behavior on the third multimedia resource.

In some embodiments, the target behavior parameters include: at least one of a click behavior parameter, a like behavior parameter, a forward behavior parameter, a comment behavior parameter, or a collection behavior parameter. For example, the target behavior parameter is a click behavior parameter, that is, an estimated click rate, which represents a predicted possibility that the account clicks the third multimedia resource, and for example, the target behavior parameter is a praise behavior parameter, that is, an estimated praise rate, which represents a predicted possibility that the account praise the third multimedia resource, and the like.

In some embodiments, for any one of the at least one third multimedia resource, the server may perform the following operations when obtaining the target behavior parameter: inputting the search word feature, the first resource feature and a second resource feature of the third multimedia resource into a target behavior model, wherein the target behavior model is used for acquiring a target behavior parameter of the input multimedia resource; weighting the search term feature, the first resource feature and the second resource feature of the third multimedia resource through the target behavior model to obtain a target behavior feature; and carrying out index normalization on the target behavior characteristics to obtain the target behavior parameters.

Illustratively, the target behavior model is DNN, the DNN includes at least one hidden layer and an index normalization layer, the server concatenates (Concat) the search term feature, the first resource feature and the second resource feature of the third multimedia resource to obtain a concatenation feature, inputs the concatenation feature into at least one hidden layer of the DNN, weights the concatenation feature through the at least one hidden layer, and outputs the target behavior feature from a last hidden layer, where the at least one hidden layer is connected in series, that is, a feature output from a previous hidden layer serves as a feature input from a next hidden layer. Then, the target behavior characteristics are input into the index normalization layer, an index normalization function is called in the index normalization layer to carry out index normalization on the target behavior characteristics, and the target behavior parameters are output.

In the process, the target behavior parameters are predicted by calling the target behavior model, so that the prediction accuracy of the target behavior parameters can be improved, and different target behavior models can be trained for different target behavior parameters, for example, if the target behavior parameters are the estimated click rate, a click rate model can be trained, and if the target behavior parameters are the estimated click rate, a click rate model can be trained, so that different target behavior models can be flexibly configured for different target behavior parameters.

In step 3043, the server obtains, from the at least one third multimedia resource, the third multimedia resource whose target behavior parameter meets the second target condition as the at least one second multimedia resource.

In some embodiments, the server, in determining whether the target behavior parameter meets the second target condition, may perform the following: and sequencing the at least one third multimedia resource according to the sequence of the target behavior parameters from large to small, and selecting the third multimedia resource with the sequence positioned at the front second target position as the at least one second multimedia resource. Wherein the second target bit is any integer number of bits greater than or equal to 1.

In the process, the second target position third multimedia resources with the largest target behavior parameters are selected from all the third multimedia resources as the second multimedia resources, which is equivalent to the fact that the second multimedia resources most likely to be interested by the user can be screened out from the recalled third multimedia resources, so that the second multimedia resources more interested by the user can be recommended according to the search behavior of the user, and the search accuracy of the resource search process is improved.

In some embodiments, the server, in determining whether the target behavior parameter meets the second target condition, may perform the following: and selecting the third multimedia resource with the target behavior parameter larger than the behavior parameter threshold value from the at least one third multimedia resource as the at least one second multimedia resource.

In the process, the third multimedia resource with the target behavior parameter larger than the behavior parameter threshold value is selected as the second multimedia resource from all the third multimedia resources, so that the number of the second multimedia resources determined in the fine ranking stage is not limited, the second multimedia resources which are possibly interested by some users are avoided being omitted, and the searching accuracy of the second multimedia resources is improved.

In some embodiments, since the terminal usually displays only a fixed number of multimedia resources in the search result page, after the server determines the second multimedia resource in the above two manners, the server may also sample the fixed number of second multimedia resources in a random sampling manner, and perform the following step 305, so as to flexibly control the number of the returned second multimedia resources.

In the

above step

3041 and 3043, the stage of recalling the third multimedia resource from the candidate multimedia resources may be regarded as a coarse screening process, the coarse screening process can ensure that the recalled third multimedia resource is not only related to the search term, but also related to the guided first multimedia resource, the stage of determining the second multimedia resource from the third multimedia resource may be regarded as a fine ranking process, the fine ranking process can ensure that the screened second multimedia resource is a resource more in line with the interest of the user, and the two-stage screening process can improve the search accuracy of the finally determined second multimedia resource.

In step 305, the server transmits the at least one second multimedia asset to the terminal.

In some embodiments, the server may send, to the terminal, related information of the at least one second multimedia resource, where the related information carries at least a resource identifier and a sequencing sequence number of the at least one second multimedia resource, and may also carry at least one of the following: a cover, a title, a brief introduction, an abstract, a content tag, a nickname of a video publisher, etc. of the at least one second multimedia asset, which is not particularly limited by the embodiments of the present disclosure.

In some embodiments, the server may encapsulate the related information of the at least one second multimedia resource by using a data Transmission Protocol to obtain a search result message corresponding to the search request, where the data Transmission Protocol may be a Transmission Control Protocol (TCP), a User Datagram Protocol (UDP), an Internet Protocol (IP), and the like, and this is not specifically limited in this embodiment of the disclosure.

In some embodiments, before sending the search result message, the server may further compress and encrypt the search result message, and the compression algorithm used for compression and the encryption algorithm used for encryption are not specifically limited in the embodiments of the present disclosure.

In step 306, the terminal receives at least one second multimedia resource returned by the server based on the search request.

In some embodiments, the terminal may receive the search result message returned by the server, and if the search result message is compressed and encrypted, the search result message may be decrypted and decompressed, where an encryption algorithm used for decryption matches an encryption algorithm used for encryption, and a decompression algorithm used for decompression matches a compression algorithm used for compression. Further, after the preprocessing, the search result message is analyzed to obtain the related information of the at least one second multimedia resource, where the related information at least carries the resource identifier and the sequencing sequence number of the at least one second multimedia resource, and in addition, may also carry at least one of the following: a cover, a title, a brief introduction, an abstract, a content tag, a nickname of a video publisher, etc. of the at least one second multimedia asset, which is not particularly limited by the embodiments of the present disclosure.

In step 307, the terminal displays the at least one second multimedia asset.

In some embodiments, the terminal may display the result page of the search, and display the at least one second multimedia resource in the result page, for example, display a cover of the at least one second multimedia resource in the result page based on the ranking number of the at least one second multimedia resource, and display a respective title under each cover of the at least one second multimedia resource, so that the user may click on the cover or title of any second multimedia resource, trigger the terminal to load the any second multimedia resource from the server, and jump to a playing interface of the any second multimedia resource to play the any second multimedia resource.

Fig. 5 is a schematic diagram of a resource searching method provided by an embodiment of the present disclosure, and as shown in fig. 5, when a user browses a first multimedia resource, a terminal provides a content tab 511 of the first multimedia resource in a playing interface 510 of the first multimedia resource, where the first multimedia resource may be referred to as a work to be guided, and the content tab 511 may be referred to as a tab button. The terminal responds to the click operation of the user on the content tag 511, sends a search request to the server, and receives 6 second multimedia resources returned by the server. Then, the user jumps from the playing interface 510 to the result page 520 for displaying the search, the cover 521 and 526 of the 6 second multimedia resources are displayed in the result page 520, and the user can click the cover of any second multimedia resource, thereby jumping from the result page 520 to the playing interface of any second multimedia resource.

In the embodiment of the present disclosure, when each second multimedia resource in the result page 520 is processed, a feature of a guided work (i.e., a first resource feature) in the play interface 510 is introduced into the recall and sorting algorithm, so that a work (i.e., a second multimedia resource) more similar to the guided work can be arranged in front in the result page 520 to increase exposure, so that when a user browses each work in the result page 520, each work and the guided work have a stronger content similarity, and the user's visual inertia is used to increase the user's consumption of the result page 520, in other words, the sorting problem of the vertically searched result page 520 can be converted into a recommendation problem, so as to recommend more works meeting the user's consumption inertia.

Furthermore, in the process of testing by applying the resource searching method provided by the embodiment of the disclosure, the site tag is used for testing, by introducing the features of the work of flow guidance into the ranking model, i.e., the target behavior model, the user is enabled to select, from among different works of flow guidance, even if the same place tag is clicked on, the ranking of each work presented in the search result page returned by each is different, the reason is that the sequencing model ranks the more similar works in the content of the guide works in the front, so that the user can find out that more similar and related works with the guide works are displayed in the result page during consumption, the visual inertia of the user consumption is met, the consumption amount of the user is increased, meanwhile, the overall similarity between the works in the result page and the guide works is improved, so that the correlation between the works in the result page and the searching behaviors is improved.

When a Point of Interest (POI) tag is taken as an example for testing, by introducing a first resource feature of a first multimedia resource, which is a diversion work clicked by a user, into a target behavior model (hereinafter, this model is abbreviated as "this model"), the correlation is greatly improved when the user performs manual gsb (good-same-bad) evaluation, wherein gsb is a shape like a: b: and c, comparing the search results returned by different models aiming at the same search word after inputting a plurality of same search words into the model and the traditional model, and comparing the advantages and the disadvantages of the performance (such as indexes of accuracy, recall rate and the like), wherein the value a represents the number of the search words with improved performance compared with the traditional model, the value b represents the number of the search words with the same performance compared with the existing model, the value c represents the number of the search words with deteriorated performance compared with the existing model, and when the value a is greater than the value c, the performance of the model is represented by the traditional model, and the larger the difference between the value a and the value c is, the more the performance of the model is represented. In the experiment, gsb for the high heat POI word was 89: 9: 9, gsb for a random POI, 57: 46: 27, the experimental results show that the posterior indexes are also greatly improved, including the click rate improvement of +2.8%, the exposure duration improvement of +4.15%, and the like. Where POI refers to any non-geographically meaningful point on the map: such as shops, bars, gas stations, hospitals, stations, etc.

In some embodiments, terminal 800 also includes one or more sensors 810. The one or more sensors 810 include, but are not limited to: acceleration sensor 811, gyro sensor 812, pressure sensor 813, fingerprint sensor 814, optical sensor 815 and proximity sensor 816.

The acceleration sensor 811 may detect the magnitude of acceleration in three coordinate axes of the coordinate system established with the terminal 800. For example, the acceleration sensor 811 may be used to detect the components of the gravitational acceleration in three coordinate axes. The processor 801 may control the touch screen 805 to display the user interface in a landscape view or a portrait view according to the gravitational acceleration signal collected by the acceleration sensor 811. The acceleration sensor 811 may also be used for acquisition of motion data of a game or a user.

The gyro sensor 812 may detect a body direction and a rotation angle of the terminal 800, and the gyro sensor 812 may cooperate with the acceleration sensor 811 to acquire a 3D motion of the user with respect to the terminal 800. From the data collected by the gyro sensor 812, the processor 801 may implement the following functions: motion sensing (such as changing the UI according to a user's tilting operation), image stabilization at the time of photographing, game control, and inertial navigation.

Pressure sensors 813 may be disposed on the side bezel of terminal 800 and/or underneath touch display 805. When the pressure sensor 813 is disposed on the side frame of the terminal 800, the holding signal of the user to the terminal 800 can be detected, and the processor 801 performs left-right hand recognition or shortcut operation according to the holding signal collected by the pressure sensor 813. When the pressure sensor 813 is disposed at a lower layer of the touch display screen 805, the processor 801 controls the operability control on the UI interface according to the pressure operation of the user on the touch display screen 805. The operability control comprises at least one of a button control, a scroll bar control, an icon control and a menu control.

The fingerprint sensor 814 is used for collecting a fingerprint of the user, and the processor 801 identifies the identity of the user according to the fingerprint collected by the fingerprint sensor 814, or the fingerprint sensor 814 identifies the identity of the user according to the collected fingerprint. Upon identifying that the user's identity is a trusted identity, the processor 801 authorizes the user to perform relevant sensitive operations including unlocking a screen, viewing encrypted information, downloading software, paying for and changing settings, etc. Fingerprint sensor 814 may be disposed on the front, back, or side of terminal 800. When a physical button or a vendor Logo is provided on the terminal 800, the fingerprint sensor 814 may be integrated with the physical button or the vendor Logo.

The optical sensor 815 is used to collect the ambient light intensity. In one embodiment, the processor 801 may control the display brightness of the touch screen 805 based on the ambient light intensity collected by the optical sensor 815. Specifically, when the ambient light intensity is high, the display brightness of the touch display screen 805 is increased; when the ambient light intensity is low, the display brightness of the touch display 805 is turned down. In another embodiment, the processor 801 may also dynamically adjust the shooting parameters of the camera assembly 806 based on the ambient light intensity collected by the optical sensor 815.

A proximity sensor 816, also known as a distance sensor, is typically provided on the front panel of the terminal 800. The proximity sensor 816 is used to collect the distance between the user and the front surface of the terminal 800. In one embodiment, when the proximity sensor 816 detects that the distance between the user and the front surface of the terminal 800 gradually decreases, the processor 801 controls the touch display 805 to switch from the bright screen state to the dark screen state; when the proximity sensor 816 detects that the distance between the user and the front surface of the terminal 800 becomes gradually larger, the processor 801 controls the touch display 805 to switch from the screen-on state to the screen-on state.
