Ontology-Based User-Defined Rules and Context-Aware Service Composition System

摘要

The World Wide Web is becoming increasingly personalized as users provide more of their information on the Web. Thus, Web ser vice functionality is becoming reliant on user profile information and context in order to provide user-specific data. In this paper, we discuss enhancements to SECE (Sense Everything, Control Everything), a plat form for context-aware service composition based on user-defined rules. We have enhanced SECE to interpret ontology descriptions of services. With this enhancement, SECE can now create user-defined rules based on the ontology description of the service and interoperate within any service domain that has an ontology description. Additionally, it can use an ontology-based service discovery system like GloServ as its service discovery back-end in order to issue more complex queries for service discovery and composition. This paper discusses the design and imple mentation of these improvements.
