The composition of web services can meet the needs of increasingly complex user by combining multiple distributed web services, which may be unavailable or inaccessible. The automatic planning can be exploited to dynamically compose web services. In this paper, we propose a model of web services composition based on multi-agent planning that integrates automatic substitution process based on communities...
Web services (WSs) can cooperate with each other to provide more valuable WSs. Current approaches for WS cooperation have typically assumed that WSs are always willing to participate in some form of cooperation, and have undermined the fact that WSs are autonomous in this open environment. This assumption, however, becomes more problematic in community-based WS cooperation due to the dynamic nature...
This paper discusses the engineering of communities of Web services with emphasis on the social interactions that arise between these Web services and hence, can put some restrictions on their behaviors. Like service parks, communities gather Web services that offer similar functionalities to users. The social interactions between Web services take place within and across communities and are captured...
This paper discusses some of the research done in the area of communities of Web services. A community allows Web services offering similar functionalities to be grouped together. One challenge that arises as a result of this grouping concerns the assessment of the level of service of the community. We refer to this level of service as Quality of Community (QoC). The QoC is important as it permits...
This paper presents an approach to developing Composite Web Services Marts (CWS-Marts). A CWS-Mart gathers ready-to-use composite Web services that users can invoke any time without going from scratch through the regular steps of discovering, selecting, and composing the necessary component Web services. In addition, this paper presents an architecture that encompasses four levels namely component,...
Community digital management is a key link to enhance the level of community information management. The paper introduces the features and advantages of ASP.NET and AJAX technology, analyzes the overall structure and main function modules of community digital management system, and realizes the community digital management system using of ASP.NET and AJAX technology. The practice shows that, the digital...
Community of Web services (CWS) is a society composed by a number of functionally identical Web services. The communities always aim to increase their reputation level in order to obtain more requests. In this paper, we propose an effective mechanism dealing with reputation assessment for communities of Web services. The proposed mechanism is based on after-service feedbacks provided by the users...
A grid service is a Web service that provides a group of well-defined connections and follows certain standards. Grid service exceptions refer to all kinds of questions that may occur in the request, response and implementation of a grid service. The research of grid service exceptions relies on the grid system structure. This paper discusses the related concepts and theorems in grid service exceptions,...
Functionally similar Web services are grouped as a community to facilitate and speed up the process of Web services discovery. This paper presents a solution to keep the Web service community highly-available to the user or application. The term highly-available refers that the Web service community can continue providing services even when master Web service (i.e., coordinator) fails operationally...
Web services communities can be seen as virtual clusters that agglomerate Web services with the same functionality (e.g., FlightBooking). However, selecting a community to deal with is a challenging task to users and providers. Reputation, besides other selection criteria, has been widely used for evaluating and ranking candidates. Interestingly, the definition of community reputation from the perspective...
This paper discusses how communities of Web services sustain the high availability of Web services engaged in composition scenarios. Availability is the proportion of time that a system is in a functioning condition. Web services offering the same functionality like HotelBooking are gathered into a single community regardless of who developed them, where they are located, and how they function. The...
