The potential to achieve dynamic, scalable and cost-effective marketplaces and eCommerce solutions has driven recent research efforts towards so-called Semantic Web Services, that are enriching Web services with machine-processable semantics. To this end, the Web Service Modeling Ontology (WSMO) provides the conceptual underpinning and a formal language for… (More)
The Web Service Modeling Language (WSML) is a language for the specification of different aspects of Semantic Web Services. It provides a formal language for the Web Service Mod-eling Ontology WSMO which is based on well-known logical formalisms, specifying one coherent language framework for the description of Semantic Web Services, starting from the… (More)
This document presents an ontology called Web Service Modeling Ontology (WSMO) for describing various aspects related to Semantic Web Services. Having the Web Service Modeling Framework (WSMF) as a starting point, we refine this framework, and develop a formal ontology and language.
Semantic Web Services enable the dynamic discovery of services based on a formal, explicit specification of the requester needs. The actual Web Services that will be used to satisfy the requester's goal are selected at run-time and, therefore, they are not known beforehand. As a consequence, determining whether the selected services can be trusted becomes… (More)
The Web Service Modeling Language (WSML) provides a framework of different language variants to describe semantic Web services. This paper presents the design rationale and relation with existing language recommendations. WSML is a frame based language with an intuitive human readable syntax and XML and RDF exchange syntaxes, as well as a mapping to OWL. It… (More)
Discovery is a central reasoning task in service-oriented architectures, concerned with detecting Web services that are usable for solving a given request. This paper presents two extensions in continuation of previous works towards goal-based Web service discovery with sophisticated semantic matchmaking. At first, we distinguish goal templates as generic… (More)
We introduce the Web Service Modeling Language WSML which provides a formal syntax and semantics for the Web Service Modeling Ontology WSMO. WSML is based on different logical formalisms, namely, Description Logics, First−Order Logic and Logic Programming, which are useful for the modeling of Semantic Web services. WSML consists of a number of variants… (More)
This document presents an ontology called Web Service Modeling Ontology (WSMO) for describing various aspects related to Semantic Web Services. Taking the Web Service Modeling Framework (WSMF) as a starting point, we refine and extend this framework, and develop an ontology and a description language.
Current technologies for Web Services are based on syntactical descriptions and, therefore, lend themselves to only limited amount of automation. Research efforts in Semantic Web Services, such as WSMO, try to overcome this major deficiency by providing a complete semantic description for Web Services and their related aspects. In this paper we present a… (More)
