Knowledge modeling for intelligent transportation system based on fuzzy ontology models
Lixin Shen · Journal of Dalian Maritime University · 2008
A fuzzy ontology model including fuzzy domain ontology and fuzzy upper ontology was developed to handle fuzzy phenomenon and uncertainty of information and knowledge of intelligent transportation system(ITS) effectively.Fuzzy concepts were introduced as values of property in fuzzy domain ontology,and ordinary relationships were extended to fuzzy relationships and intuitionistic fuzzy relationships.Fuzzy upper ontology focuses on the semantic relationships between fuzzy concepts,including set relations,order relations and equivalence relations.Taking the traffic accident analysis system for example,the paper built the transportation knowledge ontology model and information retrieval system.Results show that the model can do knowledge modeling of ITS effectively,which facilitates the information and knowledge management on the Semantic Web.
