A QoS Aware, Cognitive Parameters Based Model for the Selection of Semantic Web Services
نویسنده
چکیده
Selecting the most appropriate semantic web service is one of the important components of the semantic web service composition process. Most aspects of the Semantic Web Service (SWS) composition process such as automatic discovery, selection, and composition are tightly related to the quality of semantic web services (QoS). QoS can be defined as a part of service description and is an especially important factor for service composition (Zeng et al., 2004). In addition to the QoS, the cognitive parameters of service providers can also prove to be the deciding factors in semantic web service selection and composition. They can be used to decide on a particular SWS to invoke by the user among the numerous services discovered. Various cognitive parameters such as capability, desire, intention, commitment, trust, reputation etc. and a number of QoS parameters such as cost, response time, reliability, accuracy, security feature, execution time, exception handling feature, penalty on breaking service contract etc. have to be considered aBStraCt

In general, Policy-based approaches play an important role in the management of web services, for instance, in the choice of semantic web service and quality of services (QoS) in particular. The present research work illustrates a procedure for the web service selection among functionality similar web services based on WS-Policy semantic matching. In this study, the procedure of WS-Policy publi...

Therefore, it is required to provi...

By definition, web-services composition works on developing merely optimum coordination among a number of available web-services to provide a new composed web-service intended to satisfy some users requirements for which a single web service is not (good) enough. In this article, the formulation of the automatic web-services composition is proposed as several set-cover problems and an approxima...

Quality of service (QoS) is an important issue in the design and management of web service composition. QoS in web services consists of various non-functional factors, such as execution cost, execution time, availability, successful execution rate, and security. In recent years, the number of available web services has proliferated, and then offered the same services increasingly. The same web ...
