Discovering Web Services Using Behavioural Constraints and Ontology
The ability to locate useful on-line Web Services is becoming critical for today’s service-oriented business applications. A number of efforts have been put to enhance the service discovery process by using conceptualised knowledge, called ontology, of particular service domains to describe service characteristics.
