Service-Oriented Architecture (SOA) provides a flexible framework for web service composition. Using standard based protocols (such as SOAP and WSDL), composite services can be constructed by integrating atomic services developed independently. For each service in the composition, many service providers can offer the same function but may have different non-functional attributes (i.e. security,...

We claim that a key component of effective Web service composition, and one that has largely been ignored, is the consideration of user preferences. In this paper we propose a means of specifying and intergrating user preferences into Web service composition. To this end, we propose a means of performing automated Web service composition by exploiting generic procedures together with rich quali...

Web Services composition has received much interest from both the academic researchers and industry to support cross-enterprise application integration. Promising research projects and their prototypes are being developed. At the same time the web service environment is getting more dynamic as numerous web services are being published by the service providers in the Internet. To meet the users ...

Current Web service environment provide connection to individual services but is still deficient in semantic processing technology for the interoperability of Web services. The semantic processing of Web services is a key technology for the dynamic discovery and composition of Web services. Thus, the present study established Web service ontology to support ubiquitous environment and proposed a...

As the capability of an individual Web service is limited, it’s necessary to create new functionalities with existing Web services. Web services composition is the ability to create a new value-added service by incorporating some existing web services together. A model based colored Petri net (CPN) to provide semantic support for web service composition is proposed. The basic composite construc...

We present formal and practical foundations for Web service composition framework with composition correctness guarantees. We introduce contractual composition model based on two isomorphic description models: Contract Definition Language (XML) and abstract machines (formal notation). Composition operators (patterns) are used to perform composition which is then formally verified with respect t...

In this paper, we propose a method for automated web service composition by applying Linear Logic (LL) theorem proving. We distinguish value-added web services and core service by assuming that the core service is already selected by the user, but its functionality does not completely match the user’s requirement. Our method enables automation for combining the core service together with a set ...

Automated web service composition is one of the major promises of serviceoriented architecture, where services can be discovered and composed dynamically and automatically. To investigate the methods for composite web service construction, we conducted an experiment on creating useful composite web services from real existing web services where semantic annotations are not available. The empiri...

Ontologies are being used for construction of semantically rich service descriptions. In case of Web service composition, techniques for planning, composing, editing, reasoning and analyzing of these descriptions are required. It’s necessary to resolve semantic interoperability between services to achieve Web services coordination and collaboration. Matchmaking and merging of service descriptio...

In this paper, we propose a Hadoop-based approach for Web service management in Telecommunication and Internet domains. The basic idea of this approach is to adopt two components of Hadoop, HBase and MapReduce, to manage Web services. In HBase, we establish a HBase table based on request interface, and design a non-functional property index mechanism based on Qualify of Service (QoS) tree to di...
