Research on the Construction Method of Domain Semantic Knowledge Base Based on Freebase
Deyan Chen, Hong Zhao · 2018
In the process of constructing a domain semantic knowledge base, reusing existing domain knowledge bases not only facilitates the sharing, integration and reuse of the domain semantic knowledge base, but also can accelerate the construction of the domain semantic knowledge base. The open and fast growing Freebase database is a good data source which can be reused to construct the domain semantic knowledge base. However, extracting domain knowledge from the Freebase RDF dump faces many challenges. Aiming at these challenges and the shortcomings of existing research, this paper proposes a method to extract domain knowledge quickly, accurately and completely from the Freebase RDF dump and describe the domain knowledge using the semantic constructs in ontology standard description languages. Finally, the method of this paper is evaluated, including the comparison and analysis of related methods with work objectives, processes, software tools used, processing results and processing performance.
