Research on an Improved GuTao Method for Building Domain Ontologies

摘要

Building domain ontologies is an important topic in semantic Web researches. The GuTao method that is a kind of the formal concept analysis is used in this paper for the problem. Because the GuTao method can only process single-value attributes, the interest rate is introduced as a basis of the conversion from multi-value attributes to single-value ones. An improved GuTao method is proposed to build domain ontologies. In this method domain ontologies is represented as derivative concept lattices in a formal background to make them complete and unique. Its building process is based on rigorous mathematical foundation.
