The touch screen 190 may be a resistive type, a capacitive type, an infrared type, an EMR (Electronic Magnetic Resonance) type or an ultrasonic type acoustic waves, and the like, and may be implemented by combining one or more methods.

Next, with reference to FIG. 2, a search database construction process according to an embodiment of the present invention will be described. FIG. 2 is a diagram illustrating a process of constructing a search database according to an embodiment of the present invention.

2, in step 201, the control unit 110 executes a service application according to a user request, and displays an application screen including various service contents according to execution of the service application through a display panel of the touch screen 190 . The service application can be a variety of SNS applications, location based service applications, media service applications, and the like.

Depending on the preference, the user may enter a preference action for the displayed service content via the touch screen 190 or another user interface. The preference action may include an action indicating a user's appeal to the service content, an action indicating a user's use of the service content, or an action for using the service content for authoring a new content. For example, a preference action may be an action corresponding to recommendation, sharing, sympathy, scrapping, etc. for the service content. Or preference action may be an action that utilizes the location-based service provided by the application.

If the controller 110 detects that the user preference action occurs in step 203 while displaying the application screen including the service content according to the execution of the service application, the controller 110 proceeds to step 205.

In step 205, the controller 110 analyzes the service content corresponding to the user preference action to generate a keyword tag. The keyword tag is a keyword indicating the service content, and may be information indicating a position, a title, a name, and other related information depending on the type of the service content. For example, if the service content is content provided by a location based service, the keyword tag may be a place name, a place, a building, a business name, and the like. As another example, if the service content is video, the keyword tag may be the title of the video. Or if the service content is a movie introduction, the keyword tag may be a movie title. As another example, if a ticket is pre-purchased in a ticket advance application, the title of the program corresponding to the ticket can be a keyword tag.

When the keyword tag is generated, the controller 110 generates link information corresponding to the service content in step 207. The link information is information necessary for providing the service content to the user, and may include identification information of the service application related to the service content, and connection information necessary for loading the application screen including the service content after executing the service application.

For example, if the service content is content provided by the location-based service, connection information necessary for loading an application screen showing map information on the service content or an application screen providing a detailed description of the service content is included in the link information . As another example, if the service content is a moving image, connection information necessary for linking an application screen on which a moving image can be reproduced may be included in the link information. As another example, if the service content is a ticket, the link information may include connection information necessary for displaying an application screen for providing guidance information on a program corresponding to the ticket.

When the link information generation is completed, the controller 110 matches the keyword tag and the link information in step 209 and stores the keyword tag and the link information in the search database.

In the above-described FIG. 2, link information is generated after keyword tag generation. However, the order of generating keyword tags and link information is not limited to the above description. Next, referring to FIG. 3, a process of searching for a keyword using the search database constructed according to the procedure of FIG. 2 will be described. 3 is a diagram illustrating a process in which a keyword search is performed during execution of a service application according to an embodiment of the present invention. Referring to FIG. 3, in step 301, the controller 110 executes a service application according to a user request. Keyword search can be applied to various kinds of service applications. For example, text-based applications or media applications.

A text-based application is an application that is executed based on text entered by a user, such as a text service application, a chat application, a memo application, a schedule registration application, an instant messaging service application, an SNS application, A media application is an application that can search, play, and edit media. Media includes music, movies, movies, photographs, voice files, broadcasts, e-books, and the like. Examples of media applications may be photo album applications, music playback applications, video applications, e-book applications, and the like.

After the service application is executed, the control unit 110 displays a text corresponding to the user's input in step 303. [ Then, the controller 110 compares the text displayed in step 305 with a plurality of keyword tags stored in the search database, and checks whether there is a matching text. If it is determined that there is a matching text, the controller 110 proceeds to step 307 and determines the text as a keyword and sets the text as a keyword. Accordingly, the control unit 110 changes the display of the text so that the user can visually distinguish the text as a keyword. For example, the text may be highlighted and displayed. Or the text may be displayed in a different font than the other texts.

In addition, the control unit 110 searches for link information corresponding to a keyword, forms an application list using application identification information included in the retrieved link information, and links the keyword to a keyword. The application list includes the name of at least one application. In some cases, user actions for the same service content may occur in different applications. Accordingly, the search database may have a plurality of link information corresponding to one keyword tag.

Thereafter, if there is an input for selecting a keyword from the user in step 309, the controller 110 proceeds to step 311 and displays an application list related to the keyword. The user can select a desired application from the displayed list of applications.

When the user selects an application, the controller 110 executes the application using the link information including the identification information of the application selected in step 313. Then, the control unit 110 loads and displays the service content screen related to the keyword using the connection information included in the link information.

The process of generating the search database by generating the keyword tag and the link information according to the execution of the foursquare application and the process of providing the search result will be described as follows.

When the foursquare application is executed, the current position is detected, and a list of nearby sights, shops, buildings, restaurants, theaters, etc. is displayed on the application screen around the current position. The user can select any one of the items in the list, for example, restaurant A, and select and input a check-in for leaving a record of his / her location in the selected item. When the check-in input occurs, the control unit 110 determines that a preference action has occurred. Accordingly, the control unit 110 generates the restaurant A as a keyword tag. Link information including connection information necessary for displaying the application screen including the identification information of the foursquare application and the content guiding the restaurant A checked in by the user is generated. Then, the controller 110 matches the keyword tag with the link information, and stores the keyword in the search database.

Thereafter, if the user wishes to register the appointment in the restaurant A on the specific date with the schedule application of the digital device 100, the user will enter an execution request for the schedule application. Accordingly, the control unit 110 of the digital device 100 executes the schedule application. In response to the user input, the control unit 110 can sequentially display a text string of 5 o'clock appointment in the dining room A on the display panel of the touch screen 190.

The control unit 110 compares the text string entered in real time with the keyword tag. Accordingly, when inputting the text of the restaurant A is completed, the control unit 110 can detect the keyword tag of restaurant A in the search database. When the keyword tag is detected, the control unit 110 determines the inputted text restaurant A as a keyword, displays the text restaurant A by highlighting it, or displays the text by changing the font.

Then, the control unit 110 detects the identification information of the foursquare application from the link information corresponding to the restaurant A, and forms an application list. If there is an input for selecting the keyword restaurant A from the user, the control unit 110 overlaps and displays the application list, that is, the foursquare. Thereafter, if there is an input for selecting a foursquare from the user, the control unit 110 executes the foursquare application. And displays the application screen corresponding to the restaurant A and containing the contents guiding the restaurant A using the connection information included in the link information including the foursquare application identifier.

As another example, a process of constructing a search database by generating keyword tags and link information according to the execution of a Facebook application and a process of providing search results will be described as follows.

With the Facebook application running, users can enter suggested actions for music videos from singer tom. Accordingly, the controller 110 determines that a preference action has occurred for the music video of the singer tom, and generates a title of the music video, for example, today, as a keyword tag. In addition, the control unit 110 may generate tom as a keyword tag. Then, the control unit 110 generates link information including connection information for connecting a page providing today's music video videos in the Facebook application, and link information including identification information of the Facebook application. The controller 110 matches the keyword tag today with the link information and stores the keyword in the search database. Also, the controller 110 may match the name of the artist, that is, tom and the link information, and store the information in the search database.

Thereafter, the user may mention today's music video of the singer tom during a conversation using a text message with another user. In other words, in a state in which the text message application is executed, the user can input the text today into the digital device 100.

Accordingly, when inputting the text 'today' is completed, the control unit 110 can detect the keyword tag 'today' in the search database. When the keyword tag is detected, the control unit 110 determines the input text today as a keyword, highlights the text today and displays it, or displays the text by changing the font.

Then, the control unit 110 detects the identification information of the Facebook application from the link information corresponding to today, and forms an application list. If there is an input for selecting today from the user, the control unit 110 overlaps and displays the application list, i.e., Facebook. Thereafter, if there is an input for selecting a Facebook from the user, the control unit 110 executes the Facebook application. And displays the application screen provided with today's music video using the connection information included in the link information including the Facebook application identifier, corresponding to today.

Next, with reference to FIG. 4 and FIG. 5, an example will be described in which the types of keyword tags are classified according to another embodiment of the present invention, and search results are provided in a different manner according to the types of keyword tags. In the embodiments shown in FIGS. 4 and 5, keyword tags generated in association with the media contents are divided into media keywords, and the search results corresponding to the media keywords are provided in a manner different from the search results of the other keywords.

Referring to FIG. 4, a process of constructing a search database when a service content in which a user takes a preference action is location information provided by a location-based service or media content will be described. In the embodiment of FIG. 4, when the service content is content provided by the location-based service, it is assumed that the link information further includes information indicating that the keyword tag corresponding to the content is a location keyword. If the service content is a media content, it is assumed that the link information further includes information indicating that the keywith tag corresponding to the media content is a media keyword.

Referring to FIG. 4, in step 401, the control unit 110 executes a service application and displays a corresponding service content screen on the display panel of the touch screen 190. FIG. At this time, the service content may be content or media content including location information. In the state where the service application is executed, the control unit 110 detects the position information or the preference action input for the media content from the user in step 403. [ The service application may be an SNS application, a map-based application, a location-based service application, a media application, or the like.

For example, when a running SNS application provides service content based on the current location of the device 100 and the user inputs an action using the provided location-based service content, It can be detected as a preference action input. As a specific example, in the case where the SNS application provides a service for inputting a memo together with a log record or a check-in record of the current position of the device 100, and when the user selects and uses such a service, It can be determined that a preference action input has occurred. As an actual example, this may be the "location check-in service" or "foursquare application" of the "Facebook application." As another example, in the SNS application, When the user selects such a service and selects a specific restaurant or attraction, the control unit 110 may determine that a preference action input for the location information has occurred.

As another example, when the user searches a specific location, e.g., a place, a place name, a spot, a building, a business place, and the like in a map-based application and registers the searched location as a preferred location, the control unit 110 stores the preference It can be determined that an action input has occurred.

For example, when registering information related to a preferred media content in a user profile of the SNS application, the control unit 110 may determine that a preference action input for the media content has occurred. The media contents may be music, movies, music videos, image contents, television programs, books, exhibitions, and the like.

 Or preference (favorite, recommendation, fun, share, empathy, scrap, etc.) of a specific media content is input during execution of the SNS application, the control unit 110 may determine that a preference action input for the media content has occurred.

Returning to FIG. 4, in step 405, the controller 110 generates a keyword tag for the location information or the media content in which the affinity action input is confirmed.

For example, when a preference action input for position information is detected, a position keyword tag corresponding to the position information is generated. As a specific example, it is assumed that the current location of the detected device 100 during the execution of the SNS application is "Seoul Station ", and the SNS application provides a service capable of storing log records for & The control unit 110 generates a keyword tag "Seoul Station ". Or the current position of the device 100 detected during the execution of the SNS application is "Seoul station", the SNS application provides the specific service using the "Seoul station", and if the user has an action input using this service, the control unit 110 Create a keyword tag called "Seoul Station". The location keyword tag may be a name related to the location, for example, a name of a place, a name of a building, a name of a business place, and the like, according to an embodiment of the present invention.

As another example, when a preference action input to the media content is detected, a media keyword tag corresponding to the media content is generated. As a specific example, the name of the media content registered as the preferred content in the user profile of the SNS application, the name of the person associated with the media content, and the like may be the media keyword tag. In other words, the media keyword may be the title of the music album, the title of the music, the title of the movie, the title of the book, the title of the exhibition, the title of the television program, the name of the actor, the name of the singer,

(Eg, favorite, recommendation, fun, etc.) for specific media content during the execution of the SNS application, the control unit 110 generates a name associated with the media content, a name of the artist, and the like using the media keyword tag.

Or if there is media content uploaded by the user during the execution of the SNS application, the control unit 110 generates the name related to the media content, the name of the artist, and the like with the media keyword tag.

Referring back to FIG. 4, after generating the keyword tag, the controller 110 associates the keyword tag generated in step 407 with the link information corresponding to the keyword tag, and stores the keyword tag in the search database.

When the keyword tag is a location keyword tag, the link information is associated with information indicating that the keyword tag is a location keyword, identification information of a service application related to the keyword tag, and service screen provided by the service application in association with the keyword tag And the like.

For example, if an SNS application provides a specific service related to the current location of the device 100, and the user makes an action input using a particular service, the SNS application displays a service screen associated with the particular service on the device 100 . The link information includes information necessary for requesting the SNS application to display such service screen. As a specific example, it is assumed that the current location of the detected device 100 during the execution of the SNS application is "Seoul Station ", and the SNS application provides a service capable of storing log records for & A detailed information screen related to "Seoul station" is displayed on the device 100. [ In this case, the location keyword tag is "Seoul station ", the link information related to" Seoul station " includes the identification information of the corresponding SNS application and the connection information necessary for requesting display of the detailed information screen related to & do.

If the keyword tag is a media keyword tag, the link information includes information indicating that the keyword tag is a media keyword, identification information of an application related to the keyword tag, and connection information capable of loading the media content.

Every time a service application is executed, a search database can be constructed as described above.

In step 505, the control unit 110 highlights the text corresponding to the keyword tag and displays the highlighted text as a keyword so that the user can recognize that the keyword is a keyword that can use the search database.

Thereafter, if there is a selection input for the keyword from the user in step 507, the controller 110 checks the link information of the keyword tag. If the keyword is a location keyword, the service application list associated with the keyword is displayed in step 509. A plurality of service applications may be installed in the user digital device 100, and accordingly, the same plurality of keyword tags may exist. However, the link information of each of the same plurality of keyword tags may be different. Accordingly, a plurality of service applications may be provided corresponding to the keyword selected by the user.

In step 511, the controller 110 refers to the link information corresponding to the service application selected by the user among the displayed service applications, and displays a result screen accordingly.

In other words, if the keyword tag corresponding to the keyword is a position keyword tag, the control unit 110 drives the service application selected by the user using the keyword tag link information, and displays the service screen related to the keyword tag.

If it is determined in step 507 that the keyword corresponds to the media keyword tag, the controller 110 constructs and displays a recommendation list using the media keyword in step 513. In other words, the control unit 110 may drive a predetermined specific media service application, search for relevant media content using the media keyword, and display the search result as a recommendation list. A particular media service application may be an application that allows the purchase of media content.

Next, referring to FIG. 6, an example will be described in which a media application automatically retrieves a user's preferred media content at the time of execution and provides the retrieved media content to the user, according to another embodiment of the present invention.
