A cheap domain ontology construction method based on graph generation and conversion method

Traditional domain ontology construction methods are usually lack of generality because they will suffer from either high resource dependence or low ontology quality. In this paper, we propose a cheap domain ontology construction method which doesn't need any high cost resources or special concept extraction technology. It takes keywords in technical papers as domain concepts. Concepts' hierarchical relations are extracted with a graph generation and conversion method. We constructed an ontology in IT domain to evaluate the proposed method. Experimental results show that proposed method has a strong adaptability and it can construct domain ontology with high quality in both concepts and hierarchical relations.
