KNOWLEDGE GRAPH CONSTRUCTION METHOD AND APPARATUS, AND COMPUTER DEVICE AND STORAGE MEDIUM

摘要

The present application relates to the field of knowledge graph drawing of data analysis, and in particular, to a knowledge graph construction method and apparatus, and a computer device and a storage medium. The method comprises: crawling knowledge information of a plurality of webpages to be selected according to seed vocabularies; obtaining an expansion vocabulary according to a skip link; obtaining a vocabulary tag of the seed vocabulary in a webpage to be selected, and constructing a hypernym set; performing word filtering on the expansion vocabularies according to the hypernym set, and obtaining a target word set according to the filtered expansion vocabularies and the seed vocabularies; and constructing a knowledge graph according to the seed vocabularies in the hypernym set and the target word set, the expansion vocabularies and the skip link relationship. According to the knowledge graph construction method, the seed vocabulary data is obtained, skipping and expanding are carried out based on the seed vocabulary data to obtain skipping vocabularies, and moreover, the skipping vocabularies are classified by means of the hypernym set to obtain the target word set, and then the knowledge graph is constructed based on the target word set, so that the construction efficiency is high for special fields.
