Ontology-driven Web Services Composition techniques
MetadataShow full item record
Discovering and assembling individual Web Services into more complex yet new and more useful Web Processes is an important challenge. In this thesis, we present techniques for automatically and semi-automatically composing Web Services into Web Processes by using their ontological descriptions and relationships to other services. In Interface-Matching Automatic Composition technique, the possible compositions are obtained by checking semantic similarities between interfaces of individual services and considering the service qualities. In Human-Assisted Composition the user is allowed to select service classes and instances according to a service template from the ranked lists.
