Towards Ontology-based QoS Aggregation for Composite Web Services
نویسندگان
چکیده
Determining the QoS (quality of service) of composite Web services is of crucial importance for both service providers and consumers. However, service descriptions of constituent services are often heterogeneous which makes the aggregation of multiple single-service QoS difficult. In this paper, we address the heterogeneity problem from the perspective of knowledge engineering. We propose a QoS aggregation ontology; i.e., a formal parameter classification which can be used to determine the right aggregation for annotated QoS parameters based on workflow patterns.

Ontology-Based QoS Aggregation for Composite Web Services
Determining the QoS (quality of service) of composite Web services is of high importance for both service providers and service consumers. Heterogeneity of service descriptions, however, often hinders the aggregation of QoS parameters. We propose ontology-based QoS aggregation that integrates the semantics of QoS parameters and their aggregation into the overall aggregation process. The contrib...
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 کاملTSINGHUA SCIENCE AND TECHNOLOG Efficient Composition of Semantic Web Service with End-to-End QoS Optimization
The Efficiency of QoS-aware service composition is important since most of the service composition problems are known to be NP-hard. With the growing number of Web services, the service composition is like a decision problem on selecting services or/and execution plan to satisfy user’s end-to-end QoS requirement (e.g. response time, throughput). Composite services with same functionality may di...
متن کاملQoS-based Web Service Recommendation using Popular-dependent Collaborative Filtering
Since, most of the organizations present their services electronically, the number of functionally-equivalent web services is increasing as well as the number of users that employ those web services. Consequently, plenty of information is generated by the users and the web services that lead to the users be in trouble in finding their appropriate web services. Therefore, it is required to provi...
