Retrieval method, device and equipment based on physical knowledge graph and storage medium

Abstract

The invention discloses a retrieval method, device and equipment based on a physical knowledge graph, and a storage medium. The method comprises: querying corresponding query suggestion information inan index file according to a keyword extracted from to-be-retrieved physical knowledge information, and the query suggestion information comprises individual category information such as knowledge point information, fairness information, physical theorem information, topic information, common error information and multimedia file information; according to the query suggestion information, reference retrieval physical knowledge information with an inference relationship, queryinga solving relationship or an examination point relationship in a target file library based on the ontology webpage language, wherein the reference retrieval physical knowledge information comprises Wikipedia entries, multimedia resources and physical knowledge point information; and extracting, grouping and sortingthe reference retrieval physical knowledge information according to a query result to generate physical knowledge map information. According to the method, efficient associated knowledge network retrieval is carried out on retrieval content of the user based on the ontology file library, and the retrieval accuracy and effectiveness are greatly improved.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a retrieval method, device, equipment and storage medium based on a physical knowledge graph. Background technique [0002] With the development of the information age, human beings have entered the era of big data and no longer face the dilemma of lack of information. However, these massive data bother us, especially for learners, it is often very difficult to acquire knowledge efficiently, comprehensively, detailedly and accurately and find answers to corresponding questions. In the existing search engines, learners usually need to navigate several websites and summarize them to find satisfactory results when searching, and sometimes they may not be able to find satisfactory results. If learners want to get satisfactory results, they need to summarize the information by themselves. If the learners do not save the summarized information, they still need to summarize the i...

Problems solved by technology

If learners want to get satisfactory results, they need to summarize the information by themselves. If the learners do not save the summarized information, they still need to summarize the information again in the second query. When saving the summarized information, they will also face the organizational structure and how to find it quickly and accurately next time. problem, so that the validity of the search cannot be achieved
