Special Issue: Web Services Discovery and Composition

EDITORIAL PREFACE:


Liang-Jie Zhang, Editor-in-Chief, IBM T.J. Watson Research Center, USA

Services discovery and composition are among the key issues that decide the success of Web services technology. This issue of the International Journal of Web Services Research (JWSR) highlights the theme of a special issue: “Web Services Discovery and Composition.” Guest Editors M. Brian Blake, William K. Cheung, Andreas Wombacher, and Kwok Ching Tsui organized four articles in this special issue focused primarily on various approaches on services discovery and composition. In the fifth paper, “A Dynamic Two-Phase Commit Protocol for Adaptive Composite Services,” Weihai Yu and Calton Pu propose enhancement to traditional two-phase commit protocol to serve Web services-based applications.

This special issue explores several approaches to accomplishing the notion of web services discovery and composition. This issue is similar to recent venues that explore implementation issues in the form of a competition (Blake, 2005; WS-Challenge, 2006). This guest editorial preface discusses the general aspects of service discovery and composition that are independent of implementation details. In addition, the various contributions of the special issue with respect to the discovery/composition implementation approaches are summarized.

SPECIAL ISSUE PAPERS

PAPER ONE:


“Web Service Planner (WSPR): An Effective and Scalable Web Service Composition Algorithm”

Seog-Chan Oh, The Pennsylvania State University, USA
Dongwon Lee, The Pennsylvania State University, USA
Soundar R. T. Kumara, The Pennsylvania State University, USA

As the emergence of service-oriented architecture provides a major boost for e-commerce agility, the number of available Web services is rapidly increasing. However, when there are a large number of Web services available and no single Web service satisfies the given request, one has to “compose” multiple Web services to fulfill the goal. This article presents an AI planning-based Web service composition algorithm named Web Services Planner (WSPR). The efficiency and effectiveness of WSPR is evaluated using two publicly available test sets­EEE05 and ICEBE05. In addition to analyzing the two test sets, the authors also suggest several improvements for benchmarking Web service composition.

PAPER TWO:


“Web Service Discovery and Composition for Virtual Enterprises”

Jürgen Dorn, EC3 -electronic Commerce Competence Center, Austria
Peter Hrastnik, EC3 -electronic Commerce Competence Center, Austria
Albert Rainer, EC3 -electronic Commerce Competence Center, Austria

One main characteristic of virtual enterprises are short-term collaborations between business partners to provide efficient and individualized services to customers. This article describes the MOVE project, which targets a methodology and software framework to support such flexible collaborations based on process oriented design and communication by Web services. MOVE’s framework supports the graphical design and verification of business processes, the execution and supervision of processes in transaction-oriented environments, and the dynamic composition and optimization of processes. The composition of processes from Web services is implemented with methods from AI-planning. The authors apply answer set programming (ASP) and map Web service descriptions and customer requests into the input language of the ASP software DLV. The conclusion demonstrates the performance of the program provides implementation details, and shares thoughtful insights.

PAPER THREE:


“BITS: A Binary Tree Based Web Service Composition System”

Aoying Zhou, Fudan University, China
Sheng Huang, Fudan University, China
Xiaoling Wang, Fudan University, China

In current service-oriented applications, typically each individual Web service cannot satisfy users’ requests for Web services, but the functionalities of several Web services may be integrated to accomplish the requested task. The article introduces BITS, a Web service composition system. BITS is implemented based on a binary tree which is used to organize Web services. In this system, some search strategies and optimization techniques are developed for efficient service discovery and service composition. Extensive experiments are conducted for performance study, and the results show the efficiency and effectiveness of the methods adopted in BITS.

PAPER
FOUR:

“A Flexible Directory Query Language for the Efficient Processing of Service Composition Queries”

Walter Binder, University of Lugano, Switzerland
Ion Constantinescu, Ecole Polytechnique Fédérale de Lausanne (EPFL), Switzerland
Boi Faltings, Ecole Polytechnique Fédérale de Lausanne (EPFL), Switzerland

Service composition is a major challenge in an open environment populated by large numbers of heterogeneous services. In such a setting, the efficient interaction of directory-based service discovery with service composition engines is crucial. This article presents a Java-based directory that offers special functionality enabling effective service composition. In order to optimize the interaction of the directory with different service composition algorithms exploiting application-specific heuristics, the directory supports user-defined selection and ranking functions written in a declarative query language. Inside the directory queries are transformed and compiled to JVM bytecode which is dynamically linked into the directory. The compiled query enables a best-first search of matching directory entries, efficiently pruning the search space.

REVIEWED PAPER


“A Dynamic Two-Phase Commit Protocol for Adaptive Composite Services”

Weihai Yu, University of Tromsø, Norway
Calton Pu, Georgia Institute of Technology, USA

Next-generation applications based on Web services impose additional requirements on the use of coordination protocols with various optimizations, such as the two-phase commit protocol (2PC). This article analyzes the well-known 2PC optimizations “presumed commit” and “presumed abort,” and presents an improved 2PC that is suitable for Web-service-based applications. More specifically, the protocol allows every individual service provider to dynamically choose the most appropriate presumption for any distributed transaction. This new capability is especially useful when a composite Web service is integrating component services that make different presumptions in their commit protocols. The protocol does not introduce extra overhead to the previous 2PC variants in terms of number of messages and log records, and it is easy to understand and realize. The simulation shows that the choice of appropriate presumption has significant influence on system performance, and that in some heterogeneous settings, combining different presumptions in individual transactions outperforms adopting only one single presumption.

CALL FOR PAPERS

Mission of JWSR:

Web services are among the most important emerging technologies in the e-business, computer software and communication industries. Web services technologies will redefine the way that companies do business and exchange information in the twenty-first century. They will enhance business efficiency by enabling dynamic provisioning of resources from a pool of distributed resources. Due to the importance of the field, there is a significant amount of ongoing research in the areas. In a parallel effort, standardization organizations are actively developing standards for Web services. Web services are creating what will become one of the most significant industries of the new century. The International Journal of Web Services Research is designed to be a valuable resource providing leading technologies, development, ideas, and trends to an international readership of researchers and engineers in the field of Web Services.
