Abstract

The invention provides an encyclopedia-based cross-language knowledge graph construction method and device, and the method comprises the steps: obtaining original encyclopedia data of a target field,and enabling the original encyclopedia data to comprise at least two languages and at least two sources of original data of the target field; preprocessing the original encyclopedia data to obtain preprocessed target data; based on the preprocessed target data, executing knowledge modeling operation, and obtaining concept data, hyponymy relations between different concepts and concept attribute data; based on the preprocessed target data, executing knowledge acquisition operation to obtain instance data, a relationship between an instance and a concept and instance attribute data; and executing knowledge fusion operation to generate a knowledge graph of the target domain. According to the method, the construction of the encyclopedia-based cross-language domain knowledge graph is realized,data sources are diversified, and the construction efficiency of the knowledge graph can be effectively improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for constructing an encyclopedia-based cross-language knowledge graph. Background technique [0002] Knowledge graph is a database for storing knowledge. Knowledge graph is a concept officially proposed by Google in 2012. Its main purpose is to enhance search efficiency and improve user experience in the era of rapid Internet development and explosive growth of network data. With its excellent semantic processing technology and interconnectivity, the knowledge map has established a foundation for the intelligent application of information, and is widely used in search, question answering, intelligence analysis, etc., and promotes the development of information technology from information services to knowledge services. In recent years, all walks of life are researching the application of knowledge graphs in professional fields to better serve specifi...
