Q-SAC: Toward QoS Optimized Service Automatic Composition
, 2005
"... The emerging service grids bring together various distributed services to a ‘market ’ for clients to request and enable the integration of services across distributed, heterogeneous, and dynamic virtual organizations. In the experience of constructing and using the ChinaGrid, we meet two challenges, ..."

, optimizing the QoS of the grid resources and minimizing complexity for application users and developers. In this paper, we present Q-SAC, a QoS optimized service automatic composition model to address these problems. Two main features of Q-SAC are (1) automatic grid service composition, and (2) global level
Anytime Algorithm for QoS Web Service Composition ∗
"... The QoS-aware web service composition (WSC) problem aims at the automatic construction of a composite web servicewiththeoptimalaccumulatedQoSvalue. Itis, however, intractable to solve the QoS-aware WSC problem for large scale instances, since the problem corresponds to a global optimization problem. ..."

Adaptive service composition in flexible processes
- IEEE TRANS. SOFTWARE ENG
, 2007
"... In advanced service oriented systems, complex applications, described as abstract business processes, can be executed by invoking a number of available Web services. End users can specify different preferences and constraints and service selection can be performed dynamically identifying the best s ..."

QoS based Semi-Automatic Web Service Composition using Multi-Agents Systems
"... Abstract-This paper presents an agent and ontology based approach that supports the semi-automatic composition of Web services. A Web service is an accessible application that other applications and humans can discover and invoke to satisfy multiple needs. To reduce the complexity featuring the comp ..."

. The Web Ontology Language (OWL) is a family of knowledge representation languages for authoring ontologies. This paper provides the way to select an optimal composition of services and it also propose a framework for Semi-Automatic Web Services Composition.
Towards A QoS Modeling and Modularization Framework for Component-based Systems
- In Proceedings of the EDDOC Workshop on Advances in Quality of Service Management (AQuSerM
, 2008
"... Abstract Current domain-specific modeling (DSM) frameworks for designing component-based systems provide modeling support for system's structural as well as non-functional or quality of service (QoS) concerns. However, the focus of such frameworks on system's non-functional concerns is an ..."

that provides strong separation between the structural and nonfunctional dimensions. CQML supports independent evolution of structural metamodel of composition modeling languages as well as QoS metamodel. To evaluate, we superimpose CQML on a purely structural modeling language and automatically generate
Efficient Composition of Semantic Web Services with End-to-End QoS Optimization*
"... Abstract: The efficiency of QoS-aware service composition is important since most service composition problems are known to be NP-hard. With the growing number of web services, service composition is like a decision problem on selecting services or/and execution plans to satisfy the users ’ end-to-e ..."

-to-end QoS re-quirements (e.g. response time, throughput). Composite services with the same functionality may have dif-ferent execution plans, which may cause different end-to-end QoS. This paper presents a model combining semantic data-links and QoS, which leads to an efficient approach to automatic
A Dynamic Approach toward QoS-Aware Service Workflow Composition
- In ICWS
, 2009
"... Web service-based workflow management systems have garnered considerable attention for automating and scheduling dependent operations. Such systems often sup-port user preferences, e.g., time of completion, but with the rebirth of distributed computing via the grid/cloud, new challenges are abound: ..."

In this paper, we present a framework for integrat-ing QoS support in a service workflow composition system. The relationship between workflow execution time and ac-curacy is exploited through an automatic
Hybrid Optimization Algorithm for Large-Scale QoS-Aware Service Composition
"... Abstract—In this paper we present a hybrid approach for automatic composition of Web services that generates semantic input-output based compositions with optimal end-to-end QoS, minimizing the number of services of the resulting composition. The proposed approach has four main steps: 1) generation ..."

An End-to-End Approach for QoS-Aware Service Composition
