Service Selection Based on Distributed Ontology

For a large number of emerging web service selection problems in distributed environment, an ontology-based framework for the integration of enterprise information is proposed in this paper, and the problem how to enhance the supports to enterprises interoperability from semantic technologies is also investigated with this framwork. First, a distributed ontologies construction method supporting the description of the co-establishing service among multiple enterprises is presented. Meanwhile, the normalized templates for business information are given, and a multi-ontology mapping method is further employed to help multiple ontologies understand each other. Then, a semantic similarity based-method for service discovery is proposed. This method can improve the mutual understanding among distributed ontologies created with the data from different companies in their own common data formats, and realize the description of service semantically for both service requesters and service providers. All of the above efforts will improve the recall and the precision ratios of services matching.
