Overview of Knowledge Mapping Construction Technology

With the advent of the era of big data, knowledge engineering has received extensive attention. How to extract useful knowledge from massive data is the key to big data analysis. Knowledge map technology provides a means to extract structured knowledge from massive texts and images, and thus has broad application prospects. This paper first discusses the significance of knowledge mapping research. Secondly, it introduces the key technologies of knowledge map construction, including entity relationship recognition technology, knowledge fusion technology, entity link technology and knowledge reasoning technology. Then give an introduction to the existing open knowledge map dataset. Finally, the application case of knowledge map in intelligence analysis is given.
