In general, web service-based processes (WSBP) are distributed and composed of one or more WSBP called component web services (CWS) which are developed and controlled by third parties. Hence, the functional and quality guarantee terms made with the WSBP ...

The chronicle paradigm has been used to determine the faults in distributed systems, through the modelled of temporal relationships between observable events, which describe the patterns of the system behaviour. Normally, the diagnostic mechanisms based ...

Web service composition aims to provide added values by loosely coupling web services to accommodate users' complex requirements. Evolutionary computation techniques have been used to efficiently find near-optimal composite services to satisfy users' ...

Increasing emphasis on users' preferences and the growth of services on the web make service composition a time consuming and complicated work. In this paper, an approach for web service composition that combines overall QoS and modified graphplan is ...

Automatic Service Composition is a research direction aimed at facilitating the usage of atomic web services. Particularly, the goal is to build workflows of services that solve specific queries, which cannot be resolved by any single service from ...

In the domain of Service-Oriented Architecture, web services are selected and composed to meet users' functional and non-functional requirements. A few researchers have proposed Evolutionary Computation (EC) techniques for service composition problems, ...

Web services have become increasingly popular in recent years, given their modular nature and reusability potential. A particularly promising application is in Web service composition, where multiple individual services with specific functionalities are ...

The emergence of service-oriented architecture (SOA) has made it possible to establish easily accessible geodata web services and perform distributed geodata processing and modelling, which facilitate the provision of geo information in real time. ...

The concept of Service-Oriented Architecture, where individual services can be combined to accomplish more complex tasks, provides a flexible and reusable approach to application development. Their composition can be performed manually, however doing so ...

Service composition is an important means for integrating the individual web services to create new value added systems that can satisfy complex requirements. Such applications are subject to unexpected failure owing to the distributive and heterogeneous ...

In our earlier work, we defined criteria-based web service CBWS as a service which has 'criteria' associated with it. Criteria are a set of properties and are a part of non-functional properties NFPs of a service. Composite web services invoke one or ...

Service-oriented architecture SOA is an architectural style where the services are used instead of being physically integrated. The web services participating in a composition may evolve autonomously, making the service composition's behaviour ...

Environmental sensor networks consist of geographically distributed resource-constrained computers that use sensors to measure environmental parameters. They typically collect and distribute environmental data in near real-time using different types of ...

Today, there is a growing need for user to be able to express, and get answers to more complex requests, those including multiple functionalities, conditions, constraints and objectives. Complex requests including multiple functionalities only cannot ...

Web service composition, as one of the key aspects in web service domain, has attracted more and more research attentions. Generally, in order to provide a powerful function to a specific problematic, several web services should combine and work ...

Agent-based Web service composition has become one of the most challenging research issues. Many composition techniques and formalizations have been proposed, but they are neither mature nor flexible. They assume that each sub-task is an atomic process, ...

The potential of web services comes from web service composition, where a series of single web services are chosen and composed to perform compound functionalities. As to Web service composition technology, the key step is function-level Web service ...

Web service composition has two kinds of uncertain factors, including uncertain invocation results and uncertain quality of services. These uncertain factors affect success rate of service composition. The web service composition problem should be ...

Composition of web services involves a complex task of analyzing the various services available and deducing the most optimal solution from the list of service sequences. The web services are viewed in the form of layers interlinked with each other ...

Service Composition is an essential part of Service Oriented Architectures (SOA). The number of available alternatives for web services offering similar functional characteristics opens opportunities to maximise compositions based on criteria embedded ...
