Ontology Based Service Frequent Pattern Mining

In ubiquitous environment, it is important to provide suitable service to user according to user context. Therefore it is necessary to provide services based on the latest information to user through mining by user activity and service history. In this paper we propose a mining method based on spatio-temporal information and service ontology to search frequent service patterns using service history. In this method, we find the frequent service patterns by level-cross approach on service ontology. The proposed method is to be a basic research to find the service patterns to provide high quality service to user according to season, location and age with similar context.
