The chapter deals with group-oriented service provisioning in next-generation network (NGN). It consists of three parts: the first bringing forth user profile creation and semantic comparison; the second explaining user profile clustering and semantic classification; and the third describing social network creation and analysis. The multi-agent system A-STORM (Agent-based Service and Telecom Operations Management) is presented and elaborated as part of the proof-of-concept prototype which demonstrates provisioning of group-oriented services within NGN. As a group-oriented service, the RESPIRIS (Recommendation-based Superdistribution of Digital Goods within Implicit Social Networks) service is implemented and provisioned by using prototype’s agents. The proposed provisioning scenario is set forth, as well as provisioning process analysis presented.
