Achieving Web Services Composition – a Survey
Representing the semantics of web services and utilising the described semantic knowledge to develop and use within intelligent applications is an active research domain. Automatic composition of web services and reconfiguration of composed web services are some of the likely functions the intelligent applications ought to be performing by exploiting the semantic descriptions of services. The current approaches such as OWL-S requires generating or writing a huge volume of XML or similar code even to represent some trivial semantics.
The semantics include inputs, outputs, preconditions and effects, however, the preconditions and effects are not rich enough to reason upon the activities that services are expected to perform in general. Further a standard language or approach to define the semantic description of web services does not exist. Until such a standard language or approach is devised for proper development of semantic descriptions, such approaches will remain ad hoc and essentially all the matchmaking and compositions tasks will remain at the syntactical level rather than at the semantical level.
The authors also discuss how ontologies clarify the domain’s structure of the DAML-S/UDDI Matchmaker that expands on UDDI by providing semantic Filtering and selecting semantic web services with interactive composition techniques.

Interoperability in eGovernment through Cross-Ontology Semantic Web Service Composition
Maria Allauddin and Farooque Azam. International Journal of Computer Applications 36 9 , December Full text available. Service Oriented applications are becoming very popular due to ease of Web services Usage. One use of Web Services in computer applications is its automated Composition.
Semantic Web is the key step to Web services composition. Web services may come from different domains. In order to solve this problem, we define the Web services and related matchmaking algorithms based on keywords, we call them.
Metrics details. The complexity and inter-related nature of biological data poses a difficult challenge for data and tool integration. There has been a proliferation of interoperability standards and projects over the past decade, none of which has been widely adopted by the bioinformatics community. Recent attempts have focused on the use of semantics to assist integration, and Semantic Web technologies are being welcomed by this community.
SADI – Semantic Automated Discovery and Integration – is a lightweight set of fully standards-compliant Semantic Web service design patterns that simplify the publication of services of the type commonly found in bioinformatics and other scientific domains. In addition, we provide codebases that support these best-practices, and plug-in tools to popular developer and client software that dramatically simplify deployment of services by providers, and the discovery and utilization of those services by their consumers.
SADI Services are fully compliant with, and utilize only foundational Web standards; are simple to create and maintain for service providers; and can be discovered and utilized in a very intuitive way by biologist end-users. In addition, the SADI design patterns significantly improve the ability of software to automatically discover appropriate services based on user-needs, and automatically chain these into complex analytical workflows.
We show that, when resources are exposed through SADI, data compliant with a given ontological model can be automatically gathered, or generated, from these distributed, non-coordinating resources – a behaviour we have not observed in any other Semantic system.
A Framework for Dynamic Web Services Composition
Within the numerous and heterogeneous web services offered through different sources, automatic web services composition is the most convenient method for building complex business processes that permit invocation of multiple existing atomic services. The current solutions in functional web services composition lack autonomous queries of semantic matches within the parameters of web services, which are necessary in the composition of large-scale related services.
In this paper, we propose a graph-based Semantic Web Services composition system consisting of two subsystems: management time and run time. The management-time subsystem is responsible for dependency graph preparation in which a dependency graph of related services is generated automatically according to the proposed semantic matchmaking rules. The proposed approach was applied to healthcare data integration in different health organizations and was evaluated according to two aspects: execution time measurement and correctness measurement.

This document is based on a review of requirements gathered from a number of different environments to identify the scope and potential requirements for this Semantic Web Services architecture. SWSI started in the autumn of based on common interest of the researchers involved. This document describes abstract protocols for interactions between clients and Semantic Web Services and proposes other support services that may be needed in some contexts to fulfill the basic requirements of the proposed architecture.
Our goal is that this architecture provides a foundation that will support a variety of semantically enabled service deployments in a variety of current and future distributed environments, especially those building on the World Wide Web. We anticipate that the architecture will also indicate requirements for Semantic Web service description languages which are being designed by our sister committee, the SWSI Language Committee. Our approach to developing an architectural framework for Semantic Web Services is based on an identified set of roles and requirements for machine interpreted semantic descriptions in the deployment of Semantic Web Services to different distributed environments, addressed in our previously released Requirements Document.
This document summarizes and builds on the prior one by describing protocols between interacting entities or agents that can interpret and reason with these descriptions to achieve those required functions.

The Call for Participation covered the background and goals of the workshop, and explained that attendance was limited and position papers were required. A total of 53 papers were accepted by the program committee and a subset was selected for presentation. In order to meet the workshop goals, in particular reviewing use cases and existing research efforts, finding key domain concepts and essential problems to address eventually solutions , the program was divided in 4 sessions: domain boundaries and definition, use cases, framework technologies, and concluding discussion.
The goal of the first session was to understand the challenges in Frameworks for Semantics in Web services.
and automated composition of services based on formal semantic web services in different description languages and formats have been employed in different application domains For example, the semantic service matchmaker iSeM.
Ontologies: Principles, methods and applications. Uschold , M. This paper is intended to serve as a comprehensive introduction to the emerging field concerned with the design and use of ontologies. We show how the development and implementation of an explicit account of a shared understanding i. After motivating their need, we clarify just what ontologies are and what purposes they serve. We outline a methodology for developing and evaluating ontologies, first discussing informal techniques, concerning such issues as scoping, handling ambiguity, reaching agreement and producing definitions.
We then consider the benefits of and describe, a more formal approach. We re-visit the scoping phase, and discuss the role of formal languages and techniques in the specification, implementation and evaluation of ontologies. Finally, we review the state of the art and practice in this emerging field, considering various case studies, software tools for ontology development, key research issues and future prospects.
What are ontologies, and why do we need them? Chandrasekaran , B. This survey provides a conceptual introduction to ontologies and their role in information systems and ai. The authors also discuss how ontologies clarify the domain’s structure of knowledge and enable knowledge sharing.

Web services are becoming a significant part of Web applications in different fields such as e-commerce applications. Keywords : Web services, Web services modeling, Web services datatype descriptions, Extensible markup language schema datatypes, Web services description language, Understandability. Web services is a new paradigm for building distributed application based on distributed heterogeneous services.
The future Internet will be based on services, and this new trend will have a significant impact on domains such as e-commerce . E-commerce firms are turning to Web services to streamline operations and solve the interoperability problem. Web services frees system developers to concentrate on enabling their business and their customers rather than deal with interoperability headaches by writing glue code and patching systems together .
A Semantic Web Services Architecture
Recent advances in Web and information technologies with the increasing decentralization of organizational structures have resulted in massive amounts of information resources and domain-specific services in Traditional Chinese Medicine. The massive volume and diversity of information and services available have made it difficult to achieve seamless and interoperable e-Science for knowledge-intensive disciplines like TCM. Therefore, information integration and service coordination are two major challenges in e-Science for TCM.
We still lack sophisticated approaches to integrate scientific data and services for TCM e-Science. We present a comprehensive approach to build dynamic and extendable e-Science applications for knowledge-intensive disciplines like TCM based on semantic and knowledge-based techniques.

As the spread of web services, the composition of web services becomes a hot topic on both the academia and IT domains. The composition also depends on non-functional descriptions QoS. In this paper, we present an approach of web services composition based on both semantic description and QoS. The proposed approach builds a network of web services by matchmaking the semantic concepts in OWL-S, using the outputs-inputs similarity between services.
Those composed assemblies will be ranked by the QoS that provided by the consumer and the suitable one will be sent back to the consumer. This approach takes the advantages from Pellete DL Reasoner, depth-first and forward chaining algorithms.
Prefiltering Strategy to Improve Performance of Semantic Web Service Discovery

Instead, these clients will typically be interacting with a matchmaker or peer who.
This chapter elaborates the motivation for the thesis. It gives an insight into the relation between the domain of electronic government eGovernment and Semantic Web research. It outlines the interoperability challenges in eGovernment process integration and domain speci c conditions, which encourage the application of Semantic Web concepts. Furthermore, the goals of this thesis are explained and the scope of this work is clari ed. Finally, an outline of the thesis is given in the last section.
Electronic Government is a term for describing the application of information and com- munication technology ICT in public sector processes. Focus is put on process re- engineering to achieve more e ective and e cient public sector activities and to enhance the relationship between citizen and government. One cross- field problem is the integration of processes whenever di erent public agen- cies are involved in an activity.
Processes are backed by ICT systems and applications have to be interconnected to seamlessly support process integration. In order to enable process integration, applications need to provide interfaces which are accessible by other applications.
