IRS-III: A Broker-Based Approach to Semantic Web Services

Abstract

________________________________________________________________________A factor limiting the take up of Web services is that all tasks associated with the creation of an application, for example, finding, composing, and resolving mismatches between Web services have to be carried out by a software developer. Semantic Web services is a combination of semantic Web and Web service technologies that promise to alleviate these problems. In this paper we describe IRS-III, a framework for creating and executing semantic Web services, which takes a semantic broker based approach to mediating between service requesters and service providers. We describe the overall approach and the components of IRS-III from an ontological and architectural viewpoint. We then illustrate our approach through an application in the eGovernment domain.

Problem solving methods in a global networked age

“…The SEE is an abstract architecture, currently being standardized within OASIS, for brokering between service invocations and deployed services described using WSMO. Applications developed using SEE implementations (Cimpian et al, 2005;Domingue et al, 2008) have been created within real-world use within a number of European projects, such as DIP (http://dip.semanticweb.org/), demonstrating the feasibility of the approach (see, e.g., Tanasescu et al, 2007;Gugliotta et al, 2008). It is only through semantically enhanced infrastructures based on architectures such as SEE that Web services will begin to fulfill their initial promise.…”

Semantic Web Services for Satisfying SOA Requirements

“…There are four main SWS initiatives namely WSMO/L/X Framework [6], OWL-S [7], IRS-III framework [8] and METEOR-S system [9]. The first three initiatives separate explicitly between the semantic and syntactic descriptions of a Web service and link them using the concept of grounding that maps abstract concepts and data types of the semantic description to concrete data formats and communication protocols at the Fig.…”

A Formal Model for Classifying Trusted Semantic Web Services

“…The basic structure is the UPML framework [4], on which WSMO is based. The library has been specified in the OCML modelling language [8], and implemented in IRS-III [2].…”

“…The proposed formal model has been implemented within an existing SWS execution environment: IRS-III [2]. The reasons for adopting IRS-III are the following: firstly, this framework has been designed and built within our institution; secondly, WSMO (Section 2) has been incorporated and extended as the core IRS-III epistemological framework; finally, the classification library we use and extend (Section 3) is represented in OCML [8], the ontological representation language used by IRS-III.…”

“…The latter makes use of WSMO as reference approach for SWS. WSMO is in fact the underlying model of IRS-III [2], the SWS execution environment developed within our research group. As a result, we enhanced IRS-III with the trust-based selection of WS.…”
