Web Services provides almost similar functionalities, but finding best service is the basic objective of this paper. In this paper, focus on quantifiable measurements is done. The main objective of this paper is to investigate how dynamic web service discovery can be realized to satisfy a customer's QoS requirements using an approach that can be accommodated within existing basic web service protocols...
The Semantic Web Services (SWS) technology is used to describe the Web services' capabilities and content in a computer-interpretable language and improve the quality of existing tasks, such as Web Services discovery, invocation, composition and monitoring. This paper addresses the topic of defining a knowledge based system for representing Semantic Web Service ontologies according to the WSMO-Lite...
Web Services are the basic building blocks for every e-business applications now-a-days. They provide efficient reusability mechanism, thereby reducing the development time and cost. Mostly the source code of web services is unavailable to other developers who use these services. The manual effort spent by them in testing these web services is very large in order to increase the interoperability....
Web Services (WS), which are based on standard XML protocols, such as, WSDL, SOAP and UDDI, are the building blocks of Service Oriented Architecture (SOA). The aim of SOA is to automate web service tasks, such as, web service discovery, selection, composition and execution. Since XML is a syntax-based language, the automation of these tasks is still a challenge. To overcome this, web services can...
We present a method using semantic Web technologies to dynamically compose a chain of Web services that answers a stated information problem. Web services description language (WSDL) files that define the services are automatically examined and input and output messages are extracted. The XML schema definitions are converted to OWL ontology files. The ontologies derived from the different services...
The emerging Web service technologies have received increasing attention in both industry and academic communities. The interoperability it promised has made it more welcome than other integration technologies. However, Web services may not be able to interact with one another directly due to interface mismatches. It happens when the service consumer and service provider have different message signatures...
With the development of the Internet technology and software engineering, Web services has been more and more important in many universal interoperability practice. In this blooming fielding, the Web Services description language version 2.0 (WSDL 2.0) recommendation, an XML language for describing Web services, has provided in 26 June 2007 W3C. It is more and more important to construct a correct...
There are numerous existing notations and standards in the Web service community. These may be grouped broadly into three competing families, namely; Web services, semantic Web, and electronic business. Although the families are competing, we expect that applications will cut across them and there is a need to map from one to another and to analyze compatibility and other properties. Therefore we...
Web services (WS) are becoming more and more popular nowadays and service-oriented architecture (SOA) have been widely used in the construction of information systems. But most of the SOA applications are not brand new and usually evolved from legacy systems. Our research group is building a service identification framework used for the SOA reengineering of existing large-scale information applications...
The aim of this paper is to create a scenario, which offers methods to integrate ECA rules into Web services. This paper also provides a short survey on using and creating Web services based on WSDL-S and SOAP technologies and make a introduction to Semantic Web technologies : WSDL-S, OWL-S, and WSMO. We provide a JESS rule example, we serialize it into a R2ML rule (R2ML tend to become a standard...
Web services are important for creating distributed applications on the Web. In fact, they're a key enabler for service-oriented architectures that focus on service reuse and interoperability. The World Wide Web Consortium (W3C) has recently finished work on two important standards for describing Web services the Web Services Description Language (WSDL) 2.0 and Semantic Annotations for WSDL and XML...
