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.

Joint Editorial Board Meeting (International Journal of Web Services Research, International Journal of Business Process Integration and Management, International Journal of Grid and Utility Computing) will be held at ICWS/SCC 2006.

International Journal of Web Services Research (JWSR), Volume 2, Number 4, October-December 2005.

This issue of the International Journal of Web Services Research (JWSR) collects five papers that span from Web service response time enhancement, state management and formalization of Web services composition, semi-automatic Web services discovery, and a case study of authorization framework of Web services.

Shahram Ghandeharizadeh et al. investigate the performance of XML and binary formatters and the role of compression technique to reduce the response time of Web services. They consider it important to balance between the gain from compression and the overhead caused by compression. Network Adaptable Middleware(NAM) is presented to help make decisions based on various factors such as data characteristics of a Web service, available client and server processor speeds, and network characteristics. NAM reduces response time of non-multimedia Web services using compression techniques when appropriate.

Michael Weiss and Babak Esfandiari propose an approach that models unexpected interactions between Web services, and automatically detects and resolves feature interactions among Web services. Based on goal-oriented analysis and scenario modeling, their approach allows reasoning about feature interactions in terms of goal conflicts and feature deployment. Three case studies are reported to illustrate the use of the approach.

Qianhui Althea Liang and Stanley Y.W. Su formalize the Web service composition problem into a search problem in an AND/OR graph. A search algorithm is presented to search a graph to identify potential composite services that satisfy a Web service request. Interactions with service requesters lead to the update of the graph; the algorithm can be repeatedly applied to the updated graph to search for alternative templates until the result is approved.

Xiang Fu et al. consider it critical for Web services composition to analyze the realizability problem, which decides whether a Web service composition can be synthesized and generate desired conversations specified by a predefined conversation protocol. They take into consideration message contents for accurate realizability analysis. To overcome potential state-space explosion caused by the message contents, they propose symbolic analysis techniques for the realizability
conditions.

Finally, Sarath Indrakanti et al. analyze the design issues of establishing an authorization framework for Web services, especially the features required for an authorization policy language. They propose extensions to the .NET MyServices authorization service to support a range of authorization policies required in commercial systems. A healthcare system built using Web services is used as a case study to prove the effectiveness of their extended authorization model.

This issue of the International Journal of Web Services Research (JWSR) collects five papers that span from Web Services discovery and development, state management for Web Services composition, information service for Grid computing, and Web service-based personalized Web mining. Special thanks to guest editors Dr. Savas Parastatidis and Dr. Jim Webber for their help in organizing quality papers.

Swapna Oundhakar, et al. address the problem of Web service registration and discovery in a registry federation, which is a collection of autonomous but cooperating Web service registries. They present an ontologybased Web service discovery infrastructure (METEOR-S Web Service Discovery Infrastructure). The discovery algorithm is based upon quantitative measures of the syntactic similarity and the functional similarity between a specified search template and a set of registered Web Services. The empirical evaludation uses a set of Web Services from the stock domain, and preliminary results are reported.

Bing Li and Wei-Tek Tsai propose an ontology-based service-oriented methodology to develop and integrate distributed applications. In their approach, requirements specification are elicited and analyzed based upon a service’s point of view, each service is then modeled and described using ontology. That is why the design process is called Ontology and Service Oriented (OSO) programming, and the output of the procedure is called OSO code. Since business logic in OSO code is represented in a machine-understandable format, the subsequent procedure of business process integration can be performed automatically.

Wei Jie, et al. present a hierarchical information service for a computational Grid virtual organization in order to ensure the provision of essential information for a computational Grid. Three layers are identified to support the information service; namely, a virtual organization layer, a site layer, and a resource layer. Based upon performance evaluation of a set of experiments over different models of information data organization, they introduce a novel data organization model. The implementation of their information service is based on the Globus Toolkit and complies with the OGSI (Open Grid Services Infrastructure) specifications.

Marty Humphrey and Glenn Wasson argue that Web Services Resource Framework (WSRF) and WS-Notification are core elements to manage states between Web
Services components in order to support effective construction of complex Grid applications. They present an empirical study paper discussing the architectural foundations of WSRF.NET, which is an implementation of the full set of specifications for WSRF and WS-Notification on the Microsoft .NET framework. Their study discusses the architectural implications of the WSRF on the designs and implementations of both WSRF implementations and applications. The observations
and lessons learned from the WSRF.NET project provide a basis for further evaluation of the WSRF approach.

Finally, Abdelsalam (Sumi) Helal and Jingting Lu propose a Web service-based information fusion framework that intends to enable end users to collect scattered information from diverse autonomous Web Services. Based upon personal data accumulated, a repeatable process is created transparently by which newer instances of the same information can be obtained in the future. A servlet server provides an intermediary broker layer to interact with services.

International Journal of Web Services Research (JWSR), Vol. 2, Issue 2, 2005.

This issue of the International Journal of Web Services Research (JWSR) collects five papers that discuss how to transmit, select, and develop quality-required Web services.

Kevin Curran and Brendan Gallagher present the Webber, which is a middleware framework that supports reconfigurable dissemination-oriented multimedia communication. They develop a SOAP Web service to enable users to download protocol stack components such as MIME attachments, so that a protocol can be configured to meet specific needs of specific applications (e.g., multimedia applications) that common protocols do not support.

Zahir Tari et al. argue that Web services lack means to support the conversation style that is essential to business processes where communications are required. They address this missing functionality by representing a business process conversation as a finite state machine within a dynamic communication protocol called DynWES.

Reachability graphs are dynamically generated to capture the conversations between two software agents. Chen Zhou et al. propose an ontologybased approach to facilitate Web service selection with required QoS specifications. Three definition layers are identified in the ontology: the QoS Profile Layer, the QoS Property Definition Layer, and the QoS Metrics Layer. A matching algorithm is also presented, together with experimental results gathered from a prototype system.

Jan Hendrik Hausmann et al. argue that the alignment of the Web services technology to software development practices is important to facilitate dynamic Web service discovery. Their chapter proposes a modelbased approach for semantic annotation of Web services. A matching mechanism for semantic descriptions of Web services based upon graphtransformation rules is also presented.

Finally, Cristian Mateos et al. propose a programming language called MoviLog for developing intelligent mobile agents that interact with Web Services. MoviLog reduces development effort by automating mobility decisions using reactive mobility by failure and enables mobile agents constructed to invoke Web Services.

International Journal of Web Services Research (JWSR), Vol. 2, Issue 1, 2005.

This issue of the International Journal of Web Services research (JWSR) collects a couple of enhanced high quality papers which were reviewed for the 2004 IEEE International Conference on Web Services (ICWS 2004) held in San Diego. ICWS is a forum for researchers and industry practitioners to exchange information regarding advancements in the state-ofthe-art and practice of Web services, as well as to identify the emerging research topics and define the future of Web services computing. ICWS 2004 was sponsored by IEEE Computer Society’s Technical Steering Committee for Services Computing (TSC-SC).

As one of the most prestigious academic conferences in the field of Services Computing, ICWS 2004 was held at Westin Horton Plaza in San Diego, California, July 6-9, 2004. ICWS 2004 was an extremely successful conference that brought industry experts and academia researchers together to exchange the latest information and future directions of Web services and its applications. ICWS 2004 attracted about 250 registered participants from 22 countries and regions (U.S., U.K., France, China, Spain, Germany, Austria, Italy, Japan, Canada, Singapore, Australia, India, Korea, Israel, Turkey, Ireland, Norway, Sweden, Brazil, Belgium, Hong Kong, and Taiwan). As the world heads toward pervasive and Web service enabled computing, there is an increasing need for computer science, information technology, and business management communities to work together to address issues related to the design, usage, and business of Web services. A key aspect of ICWS is to bring the worlds of researchers from both computer science and business management together in a single, high-quality forum. Of the accepted papers, there were computer science papers, management information system and business papers, and what we call “bridge” papers, as they bridge the gap between the two fields. In addition, ICWS 2004 offered a strong industry track with 19 papers from researchers and practitioners working in the frontier of Web services in industry. Furthermore, this year’s technical program also contained 16 short papers in which authors gave brief descriptions of their research. Finally, the ICWS 2004 technical program also included five tutorials, reviewing the state-of-the-art in five different areas related to advances in Web services, and three poster paper sessions. Five distinguished experts and executives were invited to deliver keynote speeches at IEEE ICWS 2004. Dr. Donald F. Ferguson, IBM Fellow and Chief Architect of IBM Software Group delivered the opening keynote speech on Convergence of Web Services, Grid Services and Business Processes. Sharon Nunes, Vice President of IBM Research delivered a keynote speech on Extending the Innovation Ecosystem. Dr. Ephraim Feig, Chief Technology Officer and Chief Marketing Officer at Kintera, Inc., delivered a keynote on Going Public with Software-as-a-Service. Jay M. Tenenbaum, Chairman of CommerceNet & Director of Webify Solutions and Medstory Inc., presented a vision on Business Services Networks. Dr. Umeshwar Dayal, HP Fellow and Director of Intelligent Enterprise Technologies Laboratory at Hewlett-Packard Labs, presented Managing the Intelligent Enterprise.

This issue of JWSR contains three enhanced papers accepted for presentation at ICWS 2004 and two papers from other related conferences.

Prashant Doshi et al. introduce a Dynamic Workflow Composition Using Markov Decision Processes to model workflow composition. To account for the uncertainty over the true environmental model, and for dynamic environments, they interleave MDP-based workflow generation and Bayesian model learning.

Christian Werner et al. present a WSDLDriven SOAP Compression that explores compression strategies and gives a detailed survey and evaluation of state of the art binary encoding techniques for SOAP. They also introduce a new experimental concept for SOAP compression based on differential encoding, which makes use of the commonly available WSDL description of a SOAP Web service.

Javier Parra-Fuente et al. propose a RAWS Architecture: Reflective and Adaptable Web Service Model, which is a multilevel Web service design model based on a reflective architecture. RAWS allows both the dynamic modification of the definition and implementation structure of the Web service, and the dynamic modification of the Web service behavior in order to change the existing code or to add new functionalities.

Jia Zhang et al. introduce A Service-Oriented Multimedia Componentization Model to support Quality of Service (QoS)-centered, device-independent multimedia Web services, which seamlessly incorporates cutting-edge technologies relating to Web services. A multimedia Web service is divided into control flow and data flow, and each can be delivered via different infrastructures and channels. Enhancements are proposed to facilitate SOAP and Composite Capability/Preference Profiles (CC/PP) protocols to improve their flexibility to serve multimedia Web services.

Thomas Schmidt et al. present a Security System for Distributed Business Applications to address the security conventions, which is a major drawback of existing Web service approaches. They have developed a holistic extended enterprise authentication and authorization system to facilitate agile and secure enterprise-spanning business processes with Web service enabled application components.
