An Ontology-Based Semantic Web Service Space Organization and Management Model

摘要

Semantic Web services facilitate the handling of Web services automatically and precisely with elaborate semantic descriptions for them, which at the same time makes the interactions between them more complicated and time-consuming, and if the number of Web services involved in an task is vast, the time cost is unacceptable. This paper introduce an ontology-based multi-dimension model which organize and manage the Semantic Web services space from different aspects, and different dimensions in it can cooperate each other to locate Web Services needed quickly. This model can improve efficiency by restricting Web Services to be handled in a smaller space and reducing the time of invalid handling to those irrelevant. The implementation mechanism of the model and how to use it to support Web Service discovery and composition are both discussed.
