Service discovery and service aggregation are two crucial issues in the emerging area of
service-oriented computing (SOC). We propose a new technique for the discovery of (Web) …

A major challenge for service-oriented computing is how to discover and compose (Web)
services to build complex applications. We present a matchmaking system that exploits both …

We present a matchmaking system that exploits ontology-based (OWL-S) service
descriptions to discover service compositions capable of satisfying a client request …

Several data source discovery methods take into account the semantic heterogeneity
problems by using several Domain Ontologies (DOs). However, most of them impose a …

With the development of semantic web, more and more ontologies are developed for various
purposes. In order to evaluate these ontologies, there have emerged numerous ontology …

In this paper we introduce a new view definition language, named OntoPathView, which
combines the simplicity of XPath with the high expressiveness of RDF/S based view …

Semantic Web services provide semantically enhanced service descriptions which allow the
development of automated service discovery and composition. Yet, an efficient semantic …

Semantic-based service discovery is a major open challenge towards a wide acceptance of
Semantic Web services. In this paper we present a prototype which implements a fully …

Web service discovery is one of the key issues in the emerging area of Service-oriented
Computing. In this paper, we present a complete composition-oriented, ontology-based …
