Research on Approach of Automatical Construction of Law Ontology

摘要

Recently, tools of ontology construction tend to be mature. But it's a difficult task to build ontology by hands. The research of automatical construction of ontology is still in the primary stage, especially in the law field. Considering the above condition, this paper gives a research on approach of automatical construction of law ontology; we put forward the method of using LLR formula in the step of term abstraction to improve the precision and applying K-means clustering algorithm to obtain better relations of concepts hierarchy. Compared with the approach of constructing ontology by hands, it gets better effect on the law ontology.
