Third, synthesizing the color feature and texture features, we determine and improve a similarity calculation algorithm suitable for the object region extracting algorithm before, and do the inter-image similarity matching.

During the course of developing knowledge based systems,the similarity measurement of char data type feature is often employed,and using the measurement based on Keywords,the omittance and inaccuracy of measurement is occurred.

WEB information integration with fully semantic matching;

In order to select the optimum Web services for meeting the requirements of users,a hybrid selection strategy that gives attention to semantic matching and quality of service(QoS) attributes is proposed for Web services,especially for service composition,and a framework is analyzed accordingly.

Both QoS-aware matching and global semantic matching are considered during the global matching.

The article addresses implementation issues of semantic matchmaking of Web services using intelligent middle agents.

An ontology-based semantic matchmaking approach is proposed.

This method adequately uses the semantic relevance of the domain knowledge model and the partial ontology,and proposes the possibility of building the general ontology following the view of semantic match.

For better efficiency and accuracy, it needs semantic match between grid services to implement the service discovery, the service query, and the dynamic allocation and replacement of service.

They mainly focused on QoS quantitative match,but they are short of semantic match.
