摘要This paper proposes an ontology concept acquisition method based on heterogeneous features. We regard the Encyclopedia of China as the taxonomy of ontology, extract Web knowledge base articles as concepts and learn taxonomic relations between concepts by considering the text content, folksonomies as well as semi-structured information.We extend the Encyclopedia of China to a mega-scale global Chinese ontology which provide practical support for concept attributes extraction, non-taxonomic relations extraction and other applications such as Question Answering System. Experimental results show that the proposed method achieved 11.8% performance improvement compared to the single feature method.
