Ontology-based Association Rules Retrieval using Protege Tools

The existed methods of association rules retrieval have not given enough high-level semantic information retrieval support. In order to resolve this problem, the authors propose a new method of association rules retrieval that is based on ontology and semantic Web. Ontology-based association rules retrieval method can well deal with the problems of rule semantics sharing, rule semantics consistency and intelligibility. The authors discuss the ontology-based association rules retrieval method in detail and implement a prototype system called O-ARR using Protege tools. In this paper, the system architecture of O-ARR is firstly brought forward, and then the retrieval methods of O-ARR are listed and discussed. Several key issues of O-ARR, which include establishment of rule retrieval ontology, annotation of ontology instance, query parse and user interface, are analyzed. The method also gives a technique support for further rule information utilization, such as rule information automatic analysis and intelligent reasoning
