quality of service (qos) is an important issue in the design and management of web service composition. qos in web services consists of various non-functional factors, such as execution cost, execution time, availability, successful execution rate, and security. in recent years, the number of available web services has proliferated, and then offered the same services increasingly. the same web ...
For Web service composition, choreography has recently received great attention and demonstrated a few key advantages over orchestration such as distributed control, fairness, data efficiency, and scalability. Automated design of choreography plans, especially distributed plans for multiple roles, is more complex and has not been studied before. Existing work requires manual generation assisted...
Semantic web services development become rapidly increased as dynamic changes are occurred. Various approaches are adopted to develop composite service systematically. This paper aims to make development process easier by classifying the literature on web services composition based approaches like selection, discovery, orchestration, choreography, mediation, automatic composition to facilitate ...
UML collaboration diagrams (called communication diagrams in [8]) provide a convenient visual model for specifying Web Service choreographies. A choreography specifies the desired set of interactions among a set of Web services. We formalize the interactions among Web services as conversations, i.e., the sequence of messages exchanged among the services, recorded in the order they are sent. Thi...
Web Service Choreography Description Language is a main-stream standard for the description of peer-to-peer collaborations for the participants for service composition. To predict the performance of composite service processes gives the way to tell whether the process meet the non-functional requirements, and to choose the process with better performance from those with identical function. Unfo...
Web Services are software services that can be advertised by providers and invoked by customers using Web technologies. This concept is currently carried further to address the composition of individual services through orchestration and choreography to services processes that communicate and interact with each other. We propose an ontology framework for these Web service processes that provide...
The Business Process Execution Language (BPEL) is a process modeling language which uses standard control constructs to define a process flow. But today enterprises have to be flexible and adaptable to cope with increasing change, uncertainty and unpredictability. Automating agile business processes is still a challenge as they are normally knowledge intensive, little automated but compliance r...
Nowadays, modern applications are often constructed by reusing and assembling distributed and collaborating entities, e.g., software components, Web services, or Software as a Service in cloud computing environments. In order to facilitate the integration of independently developed components (i.e., peers) that may reside in different organizations, it is necessary to provide a global contract ...
When Web Service composition takes place in an open environment, involving services that belong to different organizations, a choreography-level registry can play a major role. Such a registry acts as a “mediator” between companies providing individual services and companies providing complex business models as choreographies. We propose a framework, called PERCHE, that supports the management ...
