Chinese Core Ontology Construction from a Bilingual Term Bank

A core ontology is a mid-level ontology which bridges the gap between an upper ontology and a domain ontology.Automatic Chinese core ontology construction can help quickly model domain knowledge.A graph based core ontology construction algorithm (COCA) is proposed to automatically construct a core ontology from an English-Chinese bilingual term bank.This algorithm computes the mapping strength from a selected Chinese term to WordNet synset with association to an upper-level SUMO concept.The strength is measured using a graph model integrated with several mapping features from multiple information sources.The features include multiple translation feature between Chinese core term and WordNet, extended string feature and Part-of-Speech feature.Evaluation of COCA repeated on an English-Chinese bilingual Term bank with more than 130K entries shows that the algorithm is improved in performance compared with our previous research and can better serve the semi-automatic construction of mid-level ontology.
