With the evolution of QoS-capable 3G wireless networks, the wireless community has been increasingly looking for a framework that can provide effective network-independent end-toend QoS control. In this article we first construct such a framework and then describe how dynamic SLA-based control can be used to achieve end-to-end QoS in a wired and wireless (UMTS) environment. The proposed framewo...

Recommender systems provide valuable support for users who are searching for products and services in e-commerce environments. Research in the field long focused on algorithms supporting the recommendation of quality&taste products such as news, books, or movies.
