Introduction The Web Services Architecture Working Group defines a Web Service as: "A software application identified by an The Web Service technology is a uniform technology URI, whose interfaces and bindings are capable of being that allows uniform and universal access via Web defined, described and discovered as XML artifacts.

that perform specific, research paper on semantic web services, encapsulated tasks via standardized web oriented mechanism. But the major drawbacks of the 3. Semantic web services Web Service technologies are their inability to automatic discovery and composition; human intervention and effort Since the existing technologies for Web Services only is required which make them unusable in the complex describe in syntactical level, it is difficult for service business environment.

requestors and service providers to interpret or represent The semantic web researchers have proposed to non-trivial statements such as the meaning of inputs and augment Web Services with a semantic description of their outputs or applicable constraints.

Semantic description of functionality in order to facilitate their discovery and Web Services can make possible for automatic discovery, integration. This technology, combination of Web Services composition and execution across heterogeneous users with Semantic Web technology, is referred as Semantic and domains. So, SWS is a Web Service which is Web Services SWS. SWS s have the potentiality to semantically rich and defined through service ontology, alter the way knowledge and business services are capable of automatic discovery, execution, composition provided and used on the web.

and interpretation. In our work, we are interested in discovery of Semantic Several approaches have already been suggested for Web Services taking into account existing approaches. adding semantic to Web Services. Or services can be using the WSMO approach. described using some ontology based description This paper presents state of the art of current enabling language.

The Major initiatives in the area of SWS s are SWS technologies and describes the approach proposed. research paper on semantic web services by W3C member submissions: like OWL-S The rest of the paper is structured as follows: in [2] and WSMO [3] and WSDL-S [4]. OWL-S services are mapped to WSDL operations, and inputs and outputs of OWL-S are mapped to WSDL messages. WSDL-S is an evolutionary and backwards compatible extension of the existing Web Services standards and descriptions language, which augments the expressivity of WSDL with semantics in an arbitrary semantic representation language.

One of the main objectives of process level to resolve interoperability problems.

This process is needed to an Web Service. automated discovery of the best Service satisfying the We give first a short overview of WSMO and in the criteria. next sections; we describe our approach in details. WSMO Overview WSMO identifies four main top-level elements as presented in figure 1: 1.

Case study overview In order to exemplify the modelling of our proposal, a scenario from research paper on semantic web services domain of e-Commerce is considered. Our scenario is based on a WSMX Server, some e- Commerce Web services like Amazon and a Java secure application which allow communication with the portal.

The client introduces the appropriate values by filling Figure 2 Architecture of the proposal. forms of the Web pages; these values will be stored in a XML file for submitting to the Goal creator tool. As a Figure 2 presents the main architecture of the proposal. result, a WSML Goal file figure 3 is created and will be The client communicates with the portal via the HTTPS submitted to the WSMX Server where some e-commerce protocol, which provides a secure communication channel.

Web Services are connected for the discovery matching. The portal allows the itineraries goals to be expressed At the end, the client receives a response of the Web using web forms for which appropriate WSMO Goal Files Service selected, research paper on semantic web services. are populated with the introduced actual values and conditions and expressed with the WSML language. Once a WSML-WSMO Goal is created with actual values it can be sent to WSMX for the execution.

The planned research can be split into the following sequence of high-level steps as presented in figure 2:  First step: Creating WSMO Goals. The requirements and behavior of the client has to be expressed as WSMO Goal. The web application provides forms where user can specify his requirements and input Figure 3 Goal Creator tool. Users may describe their desires in a very individual and specific way by filling forms input cases.

In this case, we use an extension of [6] to generate the Goals. Once the user introduces the input values, they 5. Conclusion are saved in a XML file.

It is all set to alter the way humans benefit from the web from active interaction to somewhat passive utilization through the proliferation of software agents and in particular personal assistants that can better function and thrive on the Semantic Web than the conventional web
