Semantic Web Services (SWS) is proposed to ensure Web Service core missions automation, nevertheless, a dedicated Web Service discovery technology based on SWS is desired currently. For this reason, we propose an effective SWS matching algorithm to achieve service discovery based on semantics. In the paper, we first refine core properties and requirements to apply subsumption relation to involved...
Current Web Service systems are based on "central" UDDI servers and syntactic description of Web Services, which are fragile and unscalable, and do not support Semantic Web Services. It is necessary to replace this UDDI structure with a new one. P2P is such an infrastructure, which allows the sharing of resources and services by direct interaction between equal nodes. Therefore, a discovery...
Workflows are becoming an increasingly more common paradigm to manage and control scientific applications. They are an effective technology to define composition of different pieces of knowledge, both in the application domain and in the scientific context. However, workflows are addressed in a number of different perspectives and little consensus has been reached yet on the specification, languages,...
The following topics are dealt with : SOA implementation strategy; CRM system; semantic Web services; ERP system; telecom services management; objectionable video classification; software aging state evaluation; task-driven data mining; social-MRC social consensus formation support system; user-driven geospatial Web data; AC-DC boost converter; workflow modeling; customer satisfaction; maritime logistics;...
Semantic Web services have been employed in a wide range of applications and have become a key technology in developing business operations on the Web. However, heterogeneity is a major problem of the current semantic Web service technologies. In particular, semantic Web services described by different description languages cannot work together. For example, a Web service described by OWL-S cannot...
In order to be competitive, tourism intermediaries (i.e. travel agents, tour operators, etc.) require flexible and customizable solutions to adapt the wide variety of products and services on demand according to customers' preferences. In addition, tourism intermediaries need to provide added value to customers by mapping their preferences or wishes into a composition of specific market products and...
We describe a model-driven translation approach between semantic Web service based business process models in the context of the SUPER project. In SUPER we provide a set of business process ontologies for enabling access to the business process space inside the organisation at the semantic level. One major task in this context is to handle the translations between the provided ontologies in order...
The idea behind mashups is to provide a mechanism that allows for more or less spontaneous combination of existing Web applications. Users shall thus be enabled to combine data and services according to their needs.However, existing mashup frameworks require some programming knowledge, hence are not suitable for non-expert users. In this paper, we present a system that builds on existing semantic...
Current methods of service discovery, using the same mechanism to describe both request and advertisement and does not take into account the asymmetry between the two. Service advertisement discovery is a complete description of descriptive, information-rich features, and service request description is concerned only with some of the characteristics of services, usually does not constitute a complete...
Recently, semantic Web services have been increasingly provided to search, access and manipulate information made available from autonomous and heterogeneous systems interacting in a P2P environment. Platform independency is obtained and the possibility of integrating different information sources over the Web is augmented. Service providers can act as peers on the P2P network being able to supply...
Semantic web services (SWS) promise to take service oriented computing to a new level by allowing to automatically locate and use functionality exposed as web services. At the core of SWS are solutions to the problem of SWS discovery, i.e., the problem of comparing semantic goal descriptions with semantic offer descriptions to determine services relevant to a given request. A plethora of different...
The Web-services stack of standards is designed to support the reuse and interoperation of software components on the Web. Semantic Web services envision the automated discovery and selection of Web services. The discovery and selection process finds matches between requirements and advertisements according to their semantic description. There are already some approaches available for matching of...
Advances in Internet and software technology play increasing roles in creating work environments and online services that impact our everyday living. Web service computing paradigm has revolutionized how these software applications can be developed rapidly and reliably by employing available services available in standard forms across the web. Automatic composition of Web services is necessary and...
The discovery of suitable web services for a given task is one of the major operations in SOA architecture, and researches are being done to automate this step. For the large amount of available Web services that can be expected in real-world settings, the computational costs of automated discovery based on semantic matchmaking become important. To make a discovery engine a reliable software component,...
The onset of the Semantic Web has brought many innovations for enabling assisted interactions on the World Wide Web through document annotation. Many efforts have emerged throughout the past years, including RDF, OWL,OWL-S and WSMO, all seeking to improve the current web from a static one into a more dynamic one. Semantic Web Services are an effective way to facilitate the discovery,selection and...
Establishing Web services as resources on the Web opens up highly productive but challenging new possibilities for service economies. In addition, lifting services to the semantic level enables more sophisticated means for automating the service-related management processes and the composition of arbitrary functionality into new services and businesses. In this paper we present the SOA4All approach...
The following topics are dealt with: natural language processing; content-based multimedia retrieval; audio analysis; image analysis; video analysis; speech analysis; semantic Web services; semantic-based interoperability; service integration; metadata; description languages; ontology integration; semantic system design; data mining; Web mining; context-aware sensor networks; semantic speech retrieval;...
In this paper, we introduce an agent planner architecture which has the potential to execute composite models defined using various business process languages by means of a generic workflow model. By having a generic workflow model within an agent infrastructure, different composite process models as well as various agent programming paradigms including different planning languages can be executed...
Research in the field of semantic Web services aims at automating the discovery, selection, composition and management of Web services based on semantic descriptions. However, the applicability of many solutions developed in this field is hampered by the costs associated with semantically annotating large repositories of Web services. To overcome this gap we propose a practical method for semantically...
Semantic Web services (SWS) aim at the automated discovery and orchestration of Web services on the basis of comprehensive, machine-interpretable semantic descriptions. However, heterogeneities between distinct SWS representations pose strong limitations w.r.t. interoperability and reusability. Hence, semantic level mediation, i.e. mediation between concurrent semantic representations, is a key requirement...
