| Abstract: | Purpose/Significance] Regional government microblog can record and reveal some hot events closely related to the public.This paper builds the knowledge graph of regional government microblog to improve users' knowledge acquisition efficiency.Method/Process] First,this paper captured contents of government microblogs and built a topic modeling using LDA.At the same time,we extracted the semantic triples from aforementioned contents by LTP.Second,the applied ontology of regional government microblog wes built to form the semantic structure of knowledge graph.Ultimately,Neo4j and D3.js were used to constructing,preserving and visualizing the knowledge graph.Result/Conclusion] Based on the theoretical and practical research,we built knowledge graphs of regional government microblog,combing the semantic relations between organizations,figures and terms in microblogs' contents.This paper provides thoughts and methods for the construction of knowledge graph in social media field. |
