Knowledge map construction method and system

Abstract

The present invention provides a method and system for constructing a knowledge graph, wherein the method includes: obtaining corpus information of at least one field of the knowledge graph to be constructed; performing word segmentation and part-of-speech tagging on knowledge text content fragments included in the corpus information, and obtaining keywords therein; Match the keywords with the domain ontology according to the preset rules, and obtain the knowledge element instances in the knowledge text content fragments, the attributes of the knowledge element instances, and the relationship between the knowledge element instances; the domain ontology includes: domain topics, and domain topics include At least one model of the model, the attribute of the model and the association relationship between the models; the model includes at least one knowledge element instance; according to the knowledge element instance in multiple knowledge text content fragments, the attribute of the knowledge element instance and the association between the knowledge element instances Relationships build knowledge graphs. The invention realizes the automatic construction of the knowledge graph, reduces the construction cost of the knowledge graph, and improves the construction efficiency and accuracy of the knowledge graph.

Description

Technical field [0001] The present invention relates to the field of professional digital publishing, and more particularly to a knowledge map construction method and system. Background technique [0002] Knowledge services are hot spots in the professional digital publishing field for a short period of time, and the country's large amount of capital investment in this area has also accelerated the time of knowledge services in the publication unit. However, the current knowledge service system currently in China is still a traditional literature level of knowledge services, providing traditional full-text search methods, and resource associations are only related to the relationship between literature and reference literature. [0003] In order to achieve true knowledge retrieval, construct a variety of knowledge systems supported by knowledge retrieval, it has become a key. At present, some of the leading professional publishing houses in the knowledge system construction is co...
