Web service discovery is developing as a conspicuous technology both in technical and business domains. Due to the swift growth in the number of web service registries and repositories, discovering the web services based on user request is a major concern. Though progressive and cuttingedge techniques are proposed to address these challenges in conservative environment, still it is in its criti...

In current service-oriented applications, each individual Web service usually cannot satisfy users’ requests for Web services, but the functionalities of different Web services may be integrated to accomplish requested task. This process is called Web service composition, and the resulted service is called composite Web service. The discovery and composition of Web services are two important re...

−The ability for software agents to discover, query, and task ubiquitous sensors requires machineinterpretable service descriptions, such as those proposed by the Semantic Web effort. Descriptions that support deep semantics will enable on-the-fly utilization of sensors for applications that might not have been anticipated on initial deployment. Semantic Web service discovery and dynamic compos...

Semantic Web Service (SWS) technology is developed to overcome the shortcomings of traditional standards, such as WSDL and UDDI, and enable maximal automation in all aspects of Web Service provision and use. But great improvement of capability in SWS-based service discovery is still desired. To address this issue, we present a distributed approach for Semantic Web Service publication and discov...

Web services are an important paradigm in distributed application development. Currently, many businesses are seeking to convert their applications into web services because of its ability to promote interoperability among applications. As a number of web services increase, the process of discovering appropriate web services for consumption from user’s perspective gains importance. In this pape...

The non-functional QoS (quality of service) information helps us to select a proper Web-service from the web applications, by using component services such as UDDI[1](Universal Description, Discovery, and Integration) and MDS(Monitoring and Discovery System). MDS is a suite of web services to monitor and discover resources and service on Grids, but MDS only based on function aspects. This paper...

certain advantages of service-oriented architecture have led to the spread of this type of architecture around the world. however, some special features of this type of architecture have led to more compromise between the security in the information system and other information systems. the purpose of this paper is to identify and examine the impact of factors and dimensions of the information ...

With the growth of Web Services number and with the diversification of their types and qualities, the choice of the service that complies with user preference became a fundamental issue. The task of finding the best Web service is no longer an easy task and may end to unsatisfactory result. To resolve this problem, we adopt in this paper a Web services discovery and selection approach based on ...

This paper presents three models which enable the customisation of Universal Description, Discovery and Integration (UDDI) query results, based on some pre-defined and/or real-time changing parameters. These proposed models detail the requirements, design and techniques which make ranking of Web service discovery results from a service registry possible. Our contribution is two fold: First, we ...

The vast increase of pertinent information available to drug discovery scientists means that there is a strong demand for tools and techniques for organizing and intelligently mining this information for manageable human consumption. At Indiana University, we have developed an infrastructure of chemoinformatics Web services that simplifies the access to this information and the computational te...
