All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the related art, a relational database is usually used to store idiom information, so that a user can search for information related to a specific idiom by searching for the specific idiom, or search for an idiom related to a specific keyword in an paraphrase of the idiom and related information thereof.
However, in the relational database, it is difficult for the user to acquire idiom information from more sides, for example, although both "the ancient year" and "the Mao die year" are idioms about the age, the user has difficulty in acquiring information of both idioms by searching for "the age", and thus, the related art has difficulty in satisfying the idiom use requirements of the user.
Compared with the prior art, the embodiment of the invention provides the idiom knowledge graph construction method, and a computer, a server or other electronic equipment can construct the idiom knowledge graph by using the method.
The idiom knowledge graph construction method provided by the embodiment of the invention is generally explained below.
Acquiring a plurality of idioms to be processed and description information of each idiom to be processed;
analyzing the description information of the idiom to be processed aiming at each idiom to be processed, and determining a label corresponding to the idiom to be processed;
and constructing a knowledge graph of the multiple idioms to be processed based on the incidence relation between the multiple idioms to be processed and the labels corresponding to the idioms to be processed.
As can be seen from the above, the idiom knowledge graph construction method and apparatus provided in the embodiments of the present invention can determine a corresponding tag for each idiom to be processed based on the description information, and construct a knowledge graph based on the association relationship between the tags and the idioms to be processed, when a user performs idiom query, a plurality of corresponding idioms can be determined according to a certain tag, and compared with a method of searching idioms according to a specific idiom or a specific keyword, the method and apparatus are helpful for the user to obtain idiom information from more sides, and meet the idiom use requirements of the user.
The idiom knowledge graph construction method provided by the embodiment of the invention will be described in detail through specific embodiments.
As shown in fig. 1, a flow diagram of a idiom knowledge graph construction method provided in an embodiment of the present invention includes the following steps:
s101: and acquiring a plurality of idioms to be processed and the description information of each idiom to be processed.
In some scenarios, the electronic device (execution subject) may obtain some to-be-processed idioms, and store the to-be-processed idioms, so that a user can perform operations such as query and browsing on the to-be-processed idioms. And different storage modes of the idiom to be processed correspond to different query modes of the idiom to be processed.
In this step, the idioms to be processed may be idioms with any number of words, each idiom to be processed has its corresponding description information, and these description information may describe the idioms to be processed to distinguish them from other idioms. The description information may include one or more of pronunciation, paraphrase, and provenance information of the idiom to be processed, and is not limited specifically.
S102: and analyzing the description information of the idiom to be processed aiming at each idiom to be processed, and determining a label corresponding to the idiom to be processed.
After obtaining a plurality of idioms to be processed and the description information of each idiom to be processed, the description information of each idiom to be processed can be analyzed, and the label corresponding to each idiom to be processed is respectively determined, wherein each idiom to be processed can correspond to a unique label or a plurality of labels, and different idioms can correspond to the same label or different labels, and the details are not limited.
In one implementation manner, the manner of analyzing the description information of each idiom to be processed and determining the tag corresponding to the idiom to be processed may be: firstly, performing word segmentation processing on description information to obtain a word list corresponding to a to-be-processed idiom, and then screening words with semantic similarity meeting preset conditions with the to-be-processed idiom from the word list to serve as tags corresponding to the to-be-processed idiom.
For example, the shortest path algorithm may be used to perform word segmentation processing on the description information: firstly, the description information is segmented into a plurality of word string data, and an association diagram between the word string data is constructed according to the association relationship between the word string data. And then, calculating the association diagram by using a preset word frequency probability algorithm to obtain the word frequency probability of each associated word of the word string data. And eliminating ambiguity generated when the description information is segmented according to the word frequency probability of each associated word of the word string data aiming at each word string data, thereby identifying the words in the original text data more accurately. Alternatively, an n-gram model method, a maximum matching algorithm, a cross ambiguity algorithm, and the like may also be adopted, which is not limited in the embodiment of the present invention.
In addition, the semantic similarity between each word and the to-be-processed idiom may be calculated by using a jaccard similarity coefficient algorithm or a cosine similarity algorithm, and then words whose semantic similarity with the to-be-processed idiom satisfies a preset condition are screened from the word list, or a worker may manually review the words in the word list and the to-be-processed idiom, and words whose semantic similarity with the to-be-processed idiom satisfies a preset condition are screened from the word list, where the preset condition may be a word with the highest semantic similarity or a word whose semantic similarity reaches a preset threshold, and is not particularly limited.
When the word segmentation processing is performed on the description information to obtain the word list corresponding to the idiom to be processed, the stop words and symbols in the description information can be filtered to obtain the filtering information, and then the word segmentation processing is performed on the filtering information to obtain the word list corresponding to the idiom to be processed.
Therefore, repeated or useless information in the description information can be filtered, a more effective word list is obtained, and the efficiency and the accuracy of label extraction are further improved.
In addition, before the words with the semantic similarity to the idiom to be processed meeting the preset condition are screened from the word list and used as the tags corresponding to the idiom to be processed, association summarization processing can be further performed on the words in the word list.
The relevant word of each word may be a synonym or a synonym of the word, for example, if the word is "age", the relevant word may be "age", or the relevant word may be a hypernym of the word, for example, if the word is "fifty", the relevant word may be "age", and the like. When the relevant word of each word is obtained, the word can be inquired in a preset semantic dictionary, or the word can be input into an algorithm model obtained by pre-training for calculation, so that the relevant word of the word is obtained, and the method is not limited specifically.
Therefore, words in the word list can be richer and more general, and the efficiency and the accuracy of label extraction are further improved.
For example, the descriptor "ancient rare year" indicates that the person can live to the age of seventy, rare since ancient times "," Mao die year "indicates that the descriptor is" very old, after the two idioms to be processed and the description information thereof are obtained, word segmentation processing can be carried out on the description information to obtain a word list corresponding to the idioms to be processed, wherein the word list for "ancient rare year" may be "people \ seventy years old \ rare", "Madie year" may be "old \ big", then, the words in the word list can be summarized in a higher order, for example, the related word of "seventies" is "age", "the related word of" ages "is also" age ", furthermore, the words with the highest similarity with the idioms to be processed can be screened from the word list to be used as the labels corresponding to the idioms to be processed, thus, the labels corresponding to "ancient Mao year" and "die year" may both be "age".
S103: and constructing a knowledge graph of the multiple idioms to be processed based on the incidence relation between the multiple idioms to be processed and the labels corresponding to the idioms to be processed.
The knowledge map is also called a scientific knowledge map, is a knowledge domain visual mapping map, and can describe knowledge resources and carriers thereof by using a visual technology. That is, based on the association relationship between multiple idioms to be processed and the corresponding tags of each idiom to be processed, a knowledge graph of the multiple idioms to be processed can be constructed, so that the idioms to be processed can be visually described, and therefore, the idioms and the interrelations among the idioms can be mined, analyzed, constructed, drawn and displayed by a user.
For example, the method for constructing the knowledge graph of multiple idioms to be processed based on the association relationship between the multiple idioms to be processed and the corresponding tags of each idiom to be processed may be: firstly, generating a plurality of idioms corresponding to the idioms to be processed and label entities corresponding to labels corresponding to the idioms to be processed respectively, and then establishing the association between each idiom entity and each label entity based on the association between the idioms to be processed and the labels corresponding to the idioms to be processed to obtain a knowledge graph of the idioms to be processed.
In one implementation, after constructing a plurality of knowledge maps of idioms to be processed, a user can utilize the knowledge maps to perform idiom query.
For example, a user may input any term to be queried, and after obtaining the term to be queried, the electronic device (the execution main body) may query, in the knowledge base, a tag that matches the term to be queried, as a target tag, and then output a to-be-processed idiom corresponding to the target tag. Thus, the user can inquire all idioms related to the terms to be inquired.
For example, when the user inputs "age", the electronic device (the executing entity) may query the knowledge graph for the tag matching "age", and then output the idioms to be processed corresponding to the target tag, such as "ancient rare year" and "Matom die" year ", so as to further satisfy the idiom usage requirement of the user.
As can be seen from the above, the idiom knowledge graph construction method provided in the embodiment of the present invention can determine a corresponding tag for each idiom to be processed, construct a knowledge graph based on an association relationship between the tags and the idioms to be processed, and store the knowledge graph, so that the stored idioms are more organized, so that a user can query the idioms according to the tags.
As shown in fig. 2, a schematic flow chart of another idiom knowledge graph building method provided in the embodiment of the present invention includes the following steps:
s201: and acquiring a plurality of idioms to be processed and the description information of each idiom to be processed.
In some scenarios, the electronic device (execution subject) may obtain some to-be-processed idioms, and store the to-be-processed idioms, so that a user can perform operations such as query and browsing on the to-be-processed idioms. And different storage modes of the idiom to be processed correspond to different query modes of the idiom to be processed.
In this step, the idioms to be processed may be idioms with any number of words, each idiom to be processed has its corresponding description information, and these description information may describe the idioms to be processed to distinguish them from other idioms. The description information may include one or more of pronunciation, paraphrase, and provenance information of the idiom to be processed, and is not limited specifically.
S202: and filtering stop words and symbols in the description information to obtain filtering information.
The stop words and symbols in the description information can be filtered to obtain filtered information, and then the filtered information is subjected to word segmentation to obtain a word list corresponding to the idioms to be processed.
Therefore, repeated or useless information in the description information can be filtered, a more effective word list is obtained, and the efficiency and the accuracy of label extraction are further improved.
S203: and performing word segmentation processing on the filtering information to obtain a word list corresponding to the idioms to be processed.
For example, the shortest path algorithm may be used to perform word segmentation processing on the description information: firstly, the description information is segmented into a plurality of word string data, and an association diagram between the word string data is constructed according to the association relationship between the word string data. And then, calculating the association diagram by using a preset word frequency probability algorithm to obtain the word frequency probability of each associated word of the word string data. And eliminating ambiguity generated when the description information is segmented according to the word frequency probability of each associated word of the word string data aiming at each word string data, thereby identifying the words in the original text data more accurately.
Alternatively, an n-gram model method, a maximum matching algorithm, a cross ambiguity algorithm, and the like may also be adopted, which is not limited in the embodiment of the present invention.
S204: and acquiring the associated words of each word in the word list, and adding the associated words to the word list.
The relevant word of each word may be a synonym or a synonym of the word, for example, if the word is "age", the relevant word may be "age", or the relevant word may be a hypernym of the word, for example, if the word is "fifty", the relevant word may be "age", and the like. When the relevant word of each word is obtained, the word can be inquired in a preset semantic dictionary, or the word can be input into an algorithm model obtained by pre-training for calculation, so that the relevant word of the word is obtained, and the method is not limited specifically.
S205: and judging whether the number of the words in the word list is changed, if so, returning to the S204, and if not, executing the S206.
For example, firstly, a relevant word of each word in the word list can be obtained, the relevant word is added into the word list, then, whether the number of the words in the word list changes or not is judged, if the number of the words in the word list changes, the words in the word list are continuously summarized until the number of the words in the word list does not change, and then, words whose semantic similarity to the idiom to be processed meets the preset condition are screened from the word list to serve as tags corresponding to the idiom to be processed.
Therefore, words in the word list can be richer and more general, and the efficiency and the accuracy of label extraction are further improved.
S206: and screening the words with semantic similarity meeting preset conditions with the idioms to be processed from the word list to serve as labels corresponding to the idioms to be processed.
For example, a Jacard similarity coefficient algorithm or a cosine similarity algorithm may be used to calculate the semantic similarity between each word and the to-be-processed idiom, and then a word whose semantic similarity with the to-be-processed idiom satisfies a preset condition is selected from the word list, or a worker may manually review the word and the to-be-processed idiom in the word list, and a word whose semantic similarity with the to-be-processed idiom satisfies a preset condition is selected from the word list, where the preset condition may be the word with the highest semantic similarity or the word whose semantic similarity reaches a preset threshold, and is not particularly limited.
Each idiom to be processed may correspond to a unique tag or to multiple tags, and different idioms may correspond to the same tag or to different tags, which is not limited specifically.
For example, the descriptor "ancient rare year" indicates that the person can live to the age of seventy, rare since ancient times "," Mao die year "indicates that the descriptor is" very old, after the two idioms to be processed and the description information thereof are obtained, word segmentation processing can be carried out on the description information to obtain a word list corresponding to the idioms to be processed, wherein the word list for "ancient rare year" may be "people \ seventy years old \ rare", "Madie year" may be "old \ big", then, the words in the word list can be summarized in a higher order, for example, the related word of "seventies" is "age", "the related word of" ages "is also" age ", furthermore, the words with the highest similarity with the idioms to be processed can be screened from the word list to be used as the labels corresponding to the idioms to be processed, thus, the labels corresponding to "ancient Mao year" and "die year" may both be "age".
S207: and constructing a knowledge graph of the multiple idioms to be processed based on the incidence relation between the multiple idioms to be processed and the labels corresponding to the idioms to be processed.
The knowledge map is also called a scientific knowledge map, is a knowledge domain visual mapping map, and can describe knowledge resources and carriers thereof by using a visual technology. That is, based on the association relationship between multiple idioms to be processed and the corresponding tags of each idiom to be processed, a knowledge graph of the multiple idioms to be processed can be constructed, so that the idioms to be processed can be visually described, and therefore, the idioms and the interrelations among the idioms can be mined, analyzed, constructed, drawn and displayed by a user.
For example, the method for constructing the knowledge graph of multiple idioms to be processed based on the association relationship between the multiple idioms to be processed and the corresponding tags of each idiom to be processed may be: firstly, generating a plurality of idioms corresponding to the idioms to be processed and label entities corresponding to labels corresponding to the idioms to be processed respectively, and then establishing the association between each idiom entity and each label entity based on the association between the idioms to be processed and the labels corresponding to the idioms to be processed to obtain a knowledge graph of the idioms to be processed.
In one implementation, after constructing a plurality of knowledge maps of idioms to be processed, a user can utilize the knowledge maps to perform idiom query.
For example, a user may input any term to be queried, and after obtaining the term to be queried, the electronic device (the execution main body) may query, in the knowledge base, a tag that matches the term to be queried, as a target tag, and then output a to-be-processed idiom corresponding to the target tag. Thus, the user can inquire all idioms related to the terms to be inquired.
For example, when the user inputs "age", the electronic device (the executing entity) may query the knowledge graph for the tag matching "age", and then output the idioms to be processed corresponding to the target tag, such as "ancient rare year" and "Matom die" year ", so as to further satisfy the idiom usage requirement of the user.
