| Summary: | 碩士 === 國立臺灣大學 === 資訊管理研究所 === 91 === Automatic Web services discovery, matchmaking, composition, and
execution will play an important role in future electronic
commerce environments. Service providers need a mechanism to
advertise their services to attract service users. Service users
also need a way to search the best service provider that can meet their requirements. This paper focuses on the following
questions: What language do service providers use to describe
their services and service users to describe their requirements?
How can a user discover the needed Web services easily and
efficiently? How does a service matchmaker match service
requirements against advertisements to find the best providers?
Currently, UDDI is the primary Web services registry that allows
for searching business entities or Web services by well-known
identifiers, taxonomy, and keyword based string matching with very limited semantic search ability. In order to increase the
precision of Web services searching, we propose a matchmaking
scheme that applies the Semantic Web technology. We then design
and implement a service matchmaker based on the proposed algorithm and show how it may be applied in a Web service brokering system.
