Variance in e-Business Service Discovery.

Abstract

Abstract. Automating the process of B2B partner discovery and contract negotiation is expected to significantly optimise company processes. Numerous existing proposals for discovery follow the approach where service descriptions are expressed by concept expressions in description logics (DL), and description matching is performed by well-known DL inferences. However, these approaches do not always produce results one might intuitively expect, due to a gap between the formal semantics of service descriptions and human intuition. In this paper, we address this problem by analysing the connection between the modeler’s intuition and formal logic used to operationalise discovery. Furthermore, we show how to correctly map the intuition into description logic constructs. Finally, we investigate different inferences used to realise service discovery. 1
