A Preliminary Definition of a Pragmatic and Semiotic Based Web-service Discovery Mechanism using Norm-based Computational Agent Behaviour within a SOA Context

摘要

The discovery of relevant web services in a Service Oriented Architecture (SOA) framework is crucial in a business context. Business organisations,crucially,need to make an accurate judgement regarding the suitability of web services prior to consumption. Pragmatics (in terms of illocutionary acts) and semiotics (the understanding of signs) and its own branch of pragmatics,connect at an important junction in relation to textual entities,providing a means to undertake a contextual discovery of web services. Furthermore,norms based upon shared beliefs and specifics relating to a business organisation,affect what a human agent may achieve during the web service discovery process. A preliminary web service discovery mechanism,using the theory behind semiotics,pragmatics,speech acts and deontic logic,is defined in this paper to aid human agents during the web service discovery process. The mechanism is designed to capture human intentions,communicated as speech acts,and delegate them to norm-based computational agents.
