Abstract

The invention discloses a method and a device for constructing a knowledge map. The method comprises the following steps: extracting each ontology of a predetermined scientific field, wherein, the ontology is used for abstract expression of entities in the predetermined scientific field, and determining association relations among the ontologies; constructing The ontology library according to theontology type and the relationship between ontologies. Obtaining entities of a predetermined scientific field and structured information of the entities from a predetermined data source; importing Entities and their structured information into the ontology database to construct the knowledge map of predetermined scientific fields. The invention solves the technical problem that the knowledge map constructed by the method of constructing the knowledge map in the related art is easy to lead to low efficiency of acquiring knowledge.

Description

technical field [0001] The present invention relates to the technical field of knowledge map construction, in particular to a method and device for building a knowledge map. Background technique [0002] The construction of the knowledge map refers to the establishment of the data model of the map, which is to define the structure of the entire knowledge map. There are two construction methods for knowledge graphs: top-down and bottom-up: bottom-up construction is to extract resource patterns from publicly collected data with the help of certain technical means, and add them to the knowledge base after manual review. It is mostly used for general knowledge graphs; while top-down refers to first defining the ontology and data schema for knowledge graphs based on a large amount of data, and then adding entities to the knowledge base, which is mostly used for industry knowledge graphs. For example, data science, the field of scientific study of data, is the primary path to art...
