Semantic Weaving for Context-Aware Web Service Composition
نویسندگان
چکیده
An Aspect-oriented Programming (AOP) based approach is proposed to perform context-aware service composition on the fly. It realises context-aware composition by semantically weaving context into static Web service composition. A context weaver is implemented based on the proposed approach. The proposed semantic weaving allows services to be composed in a systematic way with changing context.

Semantic Constraint and QoS-Aware Large-Scale Web Service Composition
Service-oriented architecture facilitates the running time of interactions by using business integration on the networks. Currently, web services are considered as the best option to provide Internet services. Due to an increasing number of Web users and the complexity of users’ queries, simple and atomic services are not able to meet the needs of users; and to provide complex services, it requ...
متن کاملA procedure for Web Service Selection Using WS-Policy Semantic Matching
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...
متن کاملContext-Aware Semantic Web Services Orchestration in Mobile Environments
Web services composition is a process that involves building new applications or services called composite services by assembling existing services. With the technological evolution and the mobility of the devices and thus the varieties of the environments, the development of the approaches sensitive to the context is paramount. This paper presents a comparative analysis of existing approaches ...
متن کاملAutomatic QoS-aware Web Services Composition based on Set-Cover Problem
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...
متن کاملExecuting Semantic Web Services with a Context-Aware Service Execution Agent
The need to add semantic information to web-accessible services has created a growing research activity in this area. Standard initiatives such as OWL-S and WSDL enable the automation of discovery, composition and execution of semantic web services, i.e. they create a Semantic Web, such that computer programs or agents can implement an open, reliable, large-scale dynamic network of Web Services...
