document: Agent-based semantic web services The Web Services world consists of loosely-coupled distributed systems which adapt to ad-hoc changes by the use of service descriptions that enable opportunistic service discovery . At present , these service descriptions are semantically impoverished , being concerned with describing the functional signature of the services rather than characterising their meaning . In the Semantic Web community , the DAML Services effort attempts to rectify this by providing a more expressive way of describing Web services using ontologies . However , this approach does not separate the domain-neutral communicative intent of a message ( considered in terms of speech acts ) from its domain-specific content , unlike similar developments from the multi-agent systems community . In this paper , we describe our experiences of designing and building an ontologically motivated Web Services system for situational awareness and information triage in a simulated humanitarian aid scenario . In particular , we discuss the merits of using techniques from the multi-agent systems community for separating the intentional force of messages from their content , and the implementation of these techniques within the DAML Services model .
