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.
