Knowledge graph construction method and device

Abstract

The invention provides a knowledge graph construction method and device. The method comprises the following steps: acquiring original data and a large-scale knowledge graph; performing knowledge modeling on the original data to obtain a knowledge modeling result; generating concept layer data based on the knowledge modeling result and the large-scale knowledge graph; performing knowledge acquisition on the original data, including entity extraction, entity classification and first entity attribute extraction, to obtain entities, entity categories and entity attributes; inputting the entity as a keyword into the large-scale knowledge graph, and obtaining entity related information of the entity; fusing the entity, the entity category, the entity attribute and the entity related information to obtain complete entity layer data; and constructing a new knowledge graph based on the concept layer data and the entity layer data. According to the method, construction of the knowledge graph is achieved, and meanwhile updating of the knowledge graph in the using process can be achieved through the steps.

Description

Technical field [0001] The present invention relates to the field of computer technology, and more particularly to a method and apparatus for knowledge map constructing. Background technique [0002] Knowledge map is the concept of formulating in 2012. Its main purpose is to enhance search efficiency and improve user experience in the era of high-speed development of the Internet, network data explosion growth. Knowledge spectrum has established a foundation for information intelligent applications with its excellent semantic processing technology and interconnection, and is widely used in search, question and answer, intelligence analysis, etc., promoting information technology from information services to knowledge services. In recent years, all walks of life are studying knowledge maps in professional fields, better service specific areas. However, the current knowledge maps are basically directly built and then put into use, rarely have dynamic updates and how to expand from ...
