Abstract

The embodiment of the invention discloses a subject knowledge data processing method and device based on a knowledge graph. The method comprises the steps that a simplified directed graph with tagged edges is configured to serve as a data model for representing a resource description framework document; wherein the directed graph is used as a knowledge representation model in the knowledge graph; configuring a query path mechanism of the directed graph to clarify a query range of retrieval; the method comprises the following steps: acquiring subject knowledge input through a front end, analyzing and constructing the subject knowledge to convert the subject knowledge into a logic format of a directed graph, and storing the subject knowledge in a relational database in a record format; during query, analyzing a query statement, and converting the query statement into an SQL statement for querying the relational database; then, the obtained query result is presented at the front end in an associated knowledge form; the method has the beneficial effects that the step of ontology modeling of knowledge in each domain is avoided; the relational database is utilized, so that storage is easy; and the knowledge graph is easy to query.

Description

Technical field [0001] The present invention relates to the field of software technology, and more particularly to a discipline knowledge data processing method and apparatus based on knowledge map. Background technique [0002] Building a discipline knowledge map, which is of great significance for building digital education resources, supporting students 'personalized digital learning, teachers' precision intelligent teaching, and education modernization. In July 202, the "Guidance Opinion on the Construction of Six Separation of the Ministry of Education and the construction of the new infrastructure construction" is clearly required: "... ... step-by-step construction of the discipline knowledge map. Resource classification logo, matching discipline knowledge map ... " [0003] At present, there is no unified standard in the field of data structural construction mode in the knowledge map, and the data structure of the knowledge map determines the accuracy and recall rate. Esp...
