Composition of Web Services in the ICS Architecture
نویسندگان
چکیده
This paper proposes the use of the Web Services Composition to enhance the matchmaking process acctually in use within the ICS (Intelligent Commerce System), a Business-to-Business e-commerce system. The actual matchmaking process used in the ICS considers only single services and may return a high number of false-negative results. The new approach aims to reduce the number of false-negative results through the composition of existing single services to obtain new functionality.

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 کاملQoS-Based web service composition based on genetic algorithm
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 ...
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 کاملA model for specification, composition and verification of access control policies and its application to web services
Despite significant advances in the access control domain, requirements of new computational environments like web services still raise new challenges. Lack of appropriate method for specification of access control policies (ACPs), composition, verification and analysis of them have all made the access control in the composition of web services a complicated problem. In this paper, a new indepe...
متن کاملArchitectural Plan for Constructing Fault Tolerable Workflow Engines Based on Grid Service
In this paper the design and implementation of fault tolerable architecture for scientific workflow engines is presented. The engines are assumed to be implemented as composite web services. Current architectures for workflow engines do not make any considerations for substituting faulty web services with correct ones at run time. The difficulty is to rollback the execution state of the workflo...
