Managing Web Services Communities: a Cache for Queries Optimisation

With the advance of Web Services technologies and the mergence of Web Services into the information space, tremendous opportunities for empowering users and organizations appear in various application domains including electronic commerce, travel, intelligence information gathering and analysis, health care, digital government, etc. However, the technology to organize, search, integrate these Web Services has not kept pace with the rapid growth of the available information space. The number of Web Services to be integrated may be large and continuously changing. The ubiquitous need for Web Services integration across heterogeneous information sources pushed Web Services providers to join each others into Web Services Communities. Different approaches related to the specification, management and querying of a community were proposed. Whoever, current approaches for managing and querying Web Services Communities’ lack of a general formal and clear design. Hence, we propose a framewok which enables the community management then allows community members to share reusable fragments of kow-how in order to optimize query processing among communities .To demonstrate the viability of our approach, we propose a health care community infrastructure for supporting a community management and querying as well as a prototype application that utilizes communities.
