Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

In order to solve the above technical problems, the present invention provides a Chinese information search method based on knowledge graph. Before introducing the present invention, the concept of knowledge graph is briefly introduced. The knowledge map is designed to describe various entities (such as characters, Chinese characters, music, videos, novels, etc.) or concepts that exist in the real world. Each entity or concept is identified by a globally unique ID (Identity, identification number). logo. Each attribute-value pair is used to describe the intrinsic characteristics of the entity, and the relationship is used to connect two entities and describe the relationship between them. The knowledge graph can also be regarded as a huge network graph, the nodes in the network graph represent entities or concepts, and the edges in the network graph are composed of attributes or relationships. The knowledge map is mainly to construct and maintain the above-mentioned entities and relationships, and provide support for recommendation systems, semantic understanding, and question answering in search. In addition, the knowledge map is not a static network map, it will self-adjust and update according to changes in the outside world.

Based on the above-mentioned knowledge map that can provide a service for searching knowledge map information, the present invention provides a Chinese information search method based on the knowledge map. Fig. 1 shows a flowchart of a Chinese information search method based on a knowledge graph according to an embodiment of the present invention. As shown in Fig. 1, the method at least includes the following steps S102 to S106.

Step S102, receiving a search word from a user, and analyzing the Chinese characters contained in the search word and the attribute characteristics of the Chinese characters.

Step S104, matching Chinese characters and/or attribute features of Chinese characters in the knowledge graph, and finding corresponding Chinese character data pairs.

Step S106 , using the Chinese character data pair, searching for dictionary attribute values corresponding to the attribute features of the Chinese characters, and providing the dictionary attribute values as search results to the user.

In the technical solution provided by the present invention, based on the structural characteristics of the Chinese character data pair of the knowledge map, the search words from the user are analyzed, and the Chinese characters and the attribute characteristics of the Chinese characters contained in the search words are analyzed. Subsequently, Chinese characters and/or attribute features of Chinese characters are matched in the knowledge graph, and matched Chinese character data pairs are found. Furthermore, the Chinese character data pair is used to search for the dictionary attribute value corresponding to the attribute feature of the Chinese character, and the dictionary attribute value is provided to the user as a search result. Thus, the present invention can intuitively and accurately search the dictionary attribute value corresponding to the attribute feature of the Chinese character (For example, the dictionary attribute values "zhuó, zháo, zhāo, zhe" corresponding to the attribute feature of Chinese characters "Zhuo, zhe") are provided to users as search results, which solves the problem that such information cannot be directly displayed in the search results in related technologies. Users spend more time to filter out this part of information from related web pages, thereby improving search efficiency and improving user search experience. Moreover, based on the structural characteristics of the Chinese character data pair, the present invention can search for the corresponding dictionary attribute value through the attribute characteristics of the Chinese character, and then search for the dictionary knowledge information corresponding to the dictionary attribute value, so that the relevant Chinese character dictionary knowledge information can be structured and systematically It is provided to users in an optimized manner, so that users can obtain more knowledge information.

The structure of the Chinese character data pair in the knowledge map in the embodiment of the present invention includes Chinese characters, attribute features of Chinese characters and dictionary attribute values, that is, ternary Chinese character data pairs, for example, "维-Pinyin-yan", "维-stroke-6" , "Prolong-idiom-prolong life, stretch continuously, delay time, etc.", "write-pinyin-zhuó, zháo, zhāo, zhe", "calm-pinyin-chén zhuó" and so on.

The above step S102 parses out the Chinese characters contained in the search word and the attribute characteristics of the Chinese characters, which can be realized in various ways. For example, match the search word in the pre-configured index words that contain Chinese characters and their attribute features, and then obtain the corresponding Chinese characters and their attribute features according to the matching results. "Pinyin of Yan", if the user searches for "Pinyin of Yan", the index term will be hit. Another example is to match the search term in the pre-configured regular rule containing the attribute characteristics of Chinese characters, and then obtain the corresponding Chinese character and the attribute characteristics of the Chinese character according to the matching result, such as the pre-configured regular rule "^(.+ ?)', if the user searches for "Zode's Pinyin", it will match this regular rule, that is, a regular hit. For another example, perform word segmentation processing on the search word, and match the word segmentation corresponding to the search word in the preset word category combination containing Chinese characters and their attribute characteristics, and then obtain the Chinese character corresponding to the search word and the Chinese character’s value according to the matching result attribute characteristics. For example, pre-configure "Yan" as a keyword, "Pinyin" as an attribute word, and "De" as a stop word, and then configure the combination rule of the word category, such as configuring a combination rule, the keyword attribute word, if the user Search for "Yande Pinyin", first perform word segmentation for the search term "Yande Pinyin", and the result is Yan/De/Pinyin, throw away the stop word "De", leaving "Yande Pinyin", which matches the "keyword Word attribute word" this combination rule.

Further, in the preferred solution of the present invention, more dictionary knowledge information can also be provided to users, that is, to search for dictionary information corresponding to Chinese characters and/or dictionary attribute values, and then to find Chinese characters and/or dictionary attribute values corresponding to The dictionary information for is provided to users as search results. Here, the dictionary information corresponding to Chinese characters and/or dictionary attribute values may include pinyin, radicals, traditional characters, stroke order, strokes, definitions, synonyms, idioms, antonyms, and so on.

The Chinese information search method based on the knowledge map provided by the embodiment of the present invention will be further described through specific preferred embodiments below. In this embodiment, the search word input by the user is "Zhu's pronunciation", through the above step S102 to step S106, query and get the Chinese character data pair "Zhu-Pinyin-zhuó, zháo, zhāo, zhe", and then the dictionary attribute The values "zhuó, zháo, zhāo, zhe" are provided to the user as search results. Furthermore, dictionary information corresponding to dictionary attribute values, such as radicals, traditional characters, stroke order, strokes, definitions, etc., may also be provided to the user. As shown in Figure 2, in addition to providing users with dictionary attribute values "zhuó, zháo, zhāo, zhe", the corresponding definition dictionary information is also provided. Figure 2 displays dictionary information in the form of a picture frame. In practical applications, Figure 2 The box itself can be another shape or color, or it can be hidden. Further, when the button "View More" is clicked, the displayed search results are shown in FIG. 3 . In another embodiment of the present invention, the search term input by the user is "the meaning of the character", and at this time, the Chinese character "de" contained in the search term and the attribute feature "meaning" of the Chinese character are analyzed. Then match the Chinese character "de" and/or the attribute feature "meaning" of the Chinese character in the knowledge graph, query the Chinese character data pair, and then use the Chinese character data pair to find the dictionary attribute value corresponding to the attribute feature of the Chinese character, and compare the dictionary attribute value It is provided to the user as a search result, as shown in FIG. 4 , and the pinyin information corresponding to each meaning is also displayed in the search result.
