Scenario Matching Using Functional Substitutability in Web Services

摘要

Existing web services discovery techniques mainly match the services' descriptions using keyword-based techniques. This leads to a low service discovery precision as the semantics of services and their domains are ignored. To overcome this problem, we propose a matching approach that matches web services based on their goals as well as their expected external behavior. Scenario-networks are used to partially describe the external behavior of web services. A many-to-many semantic-based matching approach for scenario networks is proposed adopting the concept of functional substitutability.
