WS community as a mean to provide an ontological organization of WSs that share the same domain of interest has realized this kind of fancy in the sense that providers can work together to compete against others outside the community. Service selection in WS community is different from the traditional service selection, since WS community should take into account its own benefits. Therefore, we propose a hybrid approach to make service selection in WS community. The approach considers the profits of both WS community and the services within it. The experimental evaluation shows that the approach has a great advantage over other approach without consideration of community＇s benefits.展开更多
