Abstract—Web services are considered as an attracting distributed approach of application/services integration over the Internet. As the number of Web Services is exponentially growing and expected to do so for the next decade, the need for categorizing and/or classifying Web Services is very crucial for their success and the success of the underlying Service Oriented architecture (SOA). Categorization aims at systematizing Web Services according to their functionalities and their Quality of Service attributes. Communities of Web Services have been used to gather Web Services based on their functionalities. In fact, Web Services in a community can offer similar and/or complementary services. In this paper, we expand Web Services communities’ classification by adding a new support layer for Quality of Service classification. This is done through Quality of Services specification, monitoring, and adaptation of Web Services within communities. A Web Service might be admitted to a community thanks to its high Quality of Service or might be ejected from a community due to its low Quality of Service. The focus of this paper is on the design and use of a managerial community to monitor and adapt Quality of Web Services (QoWS) of managerial Web Services for other communities, Web Services providers, and Web Services clients.

Index Terms—Web Services, Communities of Web Services, Quality of Web Services (QoWS), Selection of Web Services, QoWS Monitoring, and QoWS Adaptation.
