The need to manage heterogeneous resources, over heterogeneous systems requires a cognitive approach. We propose a cognitive framework based on semantic virtualization of the main internet entities: actors, resources and applications. By means of dynamic generic enablers and proper interfaces, the cognitive framework can operate over heterogeneous environments, translating them into semantic-enriched homogeneous metadata. This virtualization allows the cognitive framework to manage the available resources using advanced, technology independent algorithms. A key role is played by the interfaces which, as the paper shows, can introduce a further cognition level. Keywords: Future Internet, Cognitive paradigms, QoS, QoE, Generic Enablers, FI- WARE. 1. Introduction Future Internet design is one of the current priorities established by the UE. The FI- WARE FP7 project is currently trying to address the issues raised by such design. In this respect, this paper, starting from the FI-WARE proposal, presents some concepts which can be considered as a preliminary contribution to evolve the issues introduced in such proposal. First of all, a definition of the entities involved in the Future Internet, as well as of the Future Internet target, can be as follows:  Actors represent the entities whose requirement fulfillment is the goal of the Future Internet; for instance, Actors include users, developers, prosumers, network providers, service providers, content providers, etc.  Resources represent the entities that can be exploited for fulfilling the Actors' requirements; example of Resources include services, contents, terminals, devices, middleware functionalities, storage, computational, connectivity and networking capabilities, etc.
