  Nowadays, with the increasing number of integrated data sources, there is a
real trend to personalize mediation systems to improve user satisfaction. To
make these systems user sensitive, we propose a personalization platform called
2P-Med. 2P-Med allows personalizing any mediation system used in any domain
following a cyclic process. The process includes building and managing adequate
user profiles and sources profiles, content and quality matching, source
selection, adapting the mediator responses to user preferences and handling
user feedbacks. In this paper, we describe 2P-Med architecture and highlight
its main functionalities. We also illustrate the operation of the platform
through personalizing source selection in a travel planning assistant.
