It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 shows an exemplary system architecture 100 to which embodiments of the method for obtaining information or the apparatus for obtaining information of the present application may be applied.
As shown in fig. 1, the system architecture 100 may include terminal devices 101, 102, 103, a network 104, and a server 105. The network 104 serves as a medium for providing communication links between the terminal devices 101, 102, 103 and the server 105. Network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.
The user may use the terminal devices 101, 102, 103 to interact with the server 105 via the network 104 to receive or send messages or the like. The terminal devices 101, 102, 103 may have installed thereon various information processing applications, such as a web browser application, an input method application, an information editing application, an instant messaging tool, a mailbox client, social platform software, and the like.
The terminal devices 101, 102, 103 may be various electronic devices having a display screen and supporting information processing, including but not limited to smart phones, tablet computers, e-book readers, laptop portable computers, desktop computers, and the like.
The server 105 may be a server providing various services, for example, a server that performs data processing on query information sent from the terminal devices 101, 102, and 103 to obtain corresponding candidate entries. After receiving the query information, the server 105 searches and displays the corresponding candidate entry in the entry library according to the pinyin query information and/or the semantic query information contained in the query information.
It should be noted that the method for acquiring information provided in the embodiment of the present application may be executed by the terminal devices 101, 102, and 103 individually, or may also be executed by the terminal devices 101, 102, and 103 and the server 105 together. Accordingly, the means for acquiring information may be provided in the terminal devices 101, 102, 103, or in the server 105.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for obtaining information in accordance with the present application is shown. The method for acquiring information comprises the following steps:
In the present embodiment, the electronic device (e.g., the server 105 shown in fig. 1) on which the method for acquiring information operates may receive inquiry information from the terminal devices 101, 102, 103 with which the user acquires information, through a wired connection manner or a wireless connection manner. The query information comprises pinyin query information and/or semantic query information. It should be noted that the wireless connection means may include, but is not limited to, a 3G/4G connection, a WiFi connection, a bluetooth connection, a WiMAX connection, a Zigbee connection, a uwb (ultra wideband) connection, and other wireless connection means now known or developed in the future.
When a user needs to acquire character information meeting a specific requirement (for example, the character information may be rhymes, hypernyms, and the like), query information may be sent to the server 105 through the terminal devices 101, 102, and 103. When the user needs to obtain information meeting the rhyme-retention requirement, the query information can comprise pinyin query information; when a user needs to obtain a similar meaning word related to some specific terms, the query information may include semantic query information (i.e., the semantic query information includes the specific terms); when the user needs to obtain information simultaneously meeting the requirements of rhyme and similar meaning words, the query information can simultaneously comprise pinyin query information and semantic query information. The pinyin query information is used for querying entries corresponding to the pinyin query information; the semantic query information is used for querying the entry corresponding to the semantic query information through word vector similarity, and the word vector similarity is represented through the distance of the entry in a vector space.
In some optional implementation manners of this embodiment, the pinyin query information includes a pinyin to be queried and tone conditions corresponding to the pinyin to be queried, the pinyin to be queried is used to query a vocabulary entry matched with the pinyin to be queried, the tone conditions are used to define pronunciation of the pinyin to be queried, and the tone conditions include that the tone conditions include one tone, two tones, three tones, and/or four tones.
The above-mentioned information satisfying the rhyme-retention requirement is also taken as an example. In order to satisfy the specified rhyme-entering requirement, the pinyin query information input by the user generally comprises the pinyin to be queried and tone conditions corresponding to the pinyin to be queried. For example, the pinyin to be queried may be: jiangnan; the corresponding tone conditions may be: one sound, one sound. The pinyin query information including the pinyin to be queried and the tone condition may be in the following form: { jiangnan |11}, { jiang1| nan1}, and the like. Wherein, { jiangnan |11} indicates that the tone condition of the pinyin "jiang" to be queried is "one sound", and the tone condition of the pinyin "nan" to be queried is "one sound". { jiang _1| nan _1} has the same meaning as { jiangnan |11} and is different in form. That is, the pinyin and pitch condition to be queried may be in the form of: { spelling to be queried | tone condition } or { spelling to be queried _ tone condition | spelling to be queried _ tone condition }. The entries corresponding to the pinyin query information may be: jiangnan, and the like. When the pinyin to be queried is not changed and the tone condition is changed, the entries corresponding to the pinyin query information may be: jiang nan, etc.
Optionally, when the tone condition is not limited, the entry corresponding to the pinyin query information may be an entry having the same pinyin as the pinyin to be queried. When the pinyin to be queried is not limited, the entries corresponding to the pinyin query information can be entries with the same tone and tone conditions.
It should be noted that, according to actual needs, the forms of the pinyin to be queried and the tone condition may be various types, and are not limited to the above { pinyin to be queried | tone condition } or { pinyin to be queried _ tone condition | pinyin to be queried _ tone condition }, which is not described herein again.
Upon receiving the query information, the server 105 may query the entry candidate corresponding to the query information from the entry library.
In some optional implementation manners of this embodiment, when the pinyin to be queried includes pinyin information, the pinyin to be queried includes initials and/or finals, and querying the candidate entry corresponding to the query information from the entry library may include the following steps:
firstly, inquiring an initial entry corresponding to an initial consonant and/or a final contained in the pinyin to be inquired from an entry library through the pinyin index.
The pinyin to be queried can simultaneously comprise the initial consonant and the final, and also can only comprise the initial consonant or only comprise the final, which is determined according to the actual requirement.
When the pinyin to be queried contains pinyin information, the server 105 may query the initial entry corresponding to the initial consonant and/or the final contained in the pinyin to be queried from the entry library through the pinyin index. The pinyin index is used for inquiring the initial entry corresponding to the pinyin to be inquired from the entry library.
And secondly, determining candidate entries from the initial entries through the tone indexes.
On the basis of obtaining the initial entries, the entries meeting the tone conditions are screened out from the initial entries through tone indexes and serve as candidate entries. The tone index is used for inquiring candidate entries corresponding to tone conditions from the initial entries.
Therefore, the entry meeting the requirement of the pinyin to be inquired can be obtained through the pinyin to be inquired, the tone of the obtained entry can be further selected, and the accuracy and pertinence of obtaining the entry are improved.
In some optional implementation manners of this embodiment, when the pinyin to be queried includes text information, the pinyin information of the text information is used as the pinyin to be queried, and querying the candidate entry corresponding to the query information from the entry library may include the following steps:
firstly, inquiring an initial entry corresponding to the pinyin information of the character information contained in the pinyin to be inquired from an entry library through the pinyin index.
When the pinyin to be queried contains character information, the pinyin to be queried, which is input by the user, can be considered as the pinyin information of the character information. The server 105 then queries the corresponding initial entry from the entry library by using the pinyin index. The pinyin index is used for inquiring the initial entry corresponding to the pinyin to be inquired from the entry library.
And secondly, determining candidate entries from the initial entries through the tone indexes.
The same process is carried out as above, on the basis of obtaining the initial entries, the entries meeting the tone condition are screened out from the initial entries through the tone index to be used as candidate entries. The tone index is used for inquiring candidate entries corresponding to tone conditions from the initial entries.
It should be noted that, in practice, the server 105 may also obtain the entries from the entry library through the tone condition, and then screen out the candidate entries through the pinyin to be queried.
In some optional implementation manners of this embodiment, the method may further include a step of constructing a vocabulary entry library, a pinyin index, and a tone index, where the step of constructing the vocabulary entry library, the pinyin index, and the tone index may include the following steps:
the method comprises the steps of firstly, obtaining a corpus, and dividing the corpus into entries to obtain an entry library.
The term bank contains terms. The entries in the entry library of the present application may be from a specified corpus (e.g., an article, a book, etc.), or may be from a broader corpus (e.g., a dictionary, etc.), which is determined according to actual needs.
After obtaining the corpus, the server 105 may divide the content of the corpus into entries according to the usage habit, professional belongings, and the like, thereby obtaining an entry library corresponding to the corpus.
After the entry library is obtained, a corresponding word vector can be set for each entry. The word vectors can be set by considering the above-mentioned classification of the vocabulary entry and other factors, and the word vectors of the vocabulary entries belonging to the same classification are set to be similar values.
And secondly, constructing a pinyin index and a tone index through the pinyin information of the entries.
After obtaining the entries, the server 105 may obtain pinyin information and tone information of each entry, and obtain pinyin indexes and tone indexes corresponding to the entry library.
In some optional implementation manners of this embodiment, the querying the candidate entry corresponding to the query information from the entry library may further include: and querying candidate entries corresponding to the semantic query information from the entry library.
In practice, in order to meet the requirements of composition word filling and the like, near-meaning words of a certain category or a certain entry need to be acquired, and at this time, the entry can be acquired by a method of semantic query information.
When the query information contains semantic query information, the server 105 may search the term library for candidate terms of the semantic query information having the same or similar semantics. For example, it may be: the server 105 acquires the word vector of each entry in the entry library, and then calculates the distance between the word vector of the semantic query information and the word vector of the entry in the vector space, and uses the distance as the word vector similarity between the word vector of the semantic query information and the word vector of the entry.
It should be noted that if the semantic query information is also contained in the entry base, the word vector similarity can be directly calculated; and if the semantic query information is not contained in the vocabulary entry base, setting a word vector for the semantic query information according to the classification information of the semantic query information, and then calculating the similarity of the word vector.
It should be noted that the query information of the present application may only include pinyin query information or semantic query information, or may also include pinyin query information or semantic query information. When the query information includes pinyin query information or semantic query information, the entry corresponding to the pinyin query information may be obtained first, and then the entry obtained by the pinyin query information is screened through the semantic query information to obtain a candidate entry. Similarly, the entry corresponding to the semantic query information may be obtained first, and then the entry obtained from the semantic query information is screened by the pinyin query information to obtain candidate entries.
After the candidate entries are obtained, the candidate entries may be sorted and displayed according to conditions such as alphabetical order, frequency of use, and the like.
In some optional implementation manners of this embodiment, the sorting and displaying the candidate entries may include: and sequencing and displaying the candidate entries according to the frequency of the candidate entries appearing in the corpus or the word vector similarity between the candidate entries and the semantic query information.
When the query information only comprises pinyin query information or when the query information comprises both pinyin query information and semantic query information, entries are obtained according to the semantic query information, and then candidate entries are selected from the entries obtained by the semantic query information through the pinyin query information, and the candidate entries can be sorted and displayed according to the frequency of the candidate entries appearing in the corpus. Similarly, when the query information only includes the semantic query information, or when the query information includes both the pinyin query information and the semantic query information, the entries are obtained according to the pinyin query information, and then the candidate entries are selected from the entries obtained by the pinyin query information through the semantic query information, and the word vector similarity between the candidate entries and the semantic query information can be ranked and displayed.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for acquiring information according to the present embodiment. In the application scenario of fig. 3, the query information of the user includes both pinyin query information ({ ai3| u4}) and semantic query information (cloud disk). The server 105 queries the candidate entries corresponding to the query information from the current entry library, sorts the candidate entries, and displays the sorted candidate entries as shown in fig. 3.
The method provided by the above embodiment of the application selects the candidate entry from the entry library through the pinyin query information and/or the semantic query information contained in the query information, and can acquire the candidate entry simultaneously meeting the requirements of the pinyin query information and the semantic query information; and then, the candidate entries are sorted and displayed, so that the accuracy of obtaining the entries by the user is improved.
