Instance Learning in Automatic Construction of Domain Ontology
Chunnian Liu · Jisuanji yingyong yanjiu · 2006
The importance of Ontology is being recognized in various research and application areas.Constructing domain(Ontology) takes too much time and manpower.Hence,it is of great significance to do some research on constructing domain(Ontology) automatically.Instance is an important element of Ontology.Learning instance from domain corpus is a key issue in automatic construction of domain Ontology.A domain Ontology construction system OntoAGS has been developed.Given some domain corpus,OntoAGS can construct domain Ontology automatically.The instance learning method of this system is based on pattern matching algorithm.Experiments show that OntoAGS can generally learn more instances and more accurately than text-to-onto system which is a popular Ontology semi-automatic construction system.
