Current implementations tend, however, to rely on a hard-wired similarity metric that cannot adapt. This constitutes a strong limitation in the face of evolving needs. In this paper, we propose a framework to develop dynamically adaptive decentralised recommendation systems. Our proposal supports a decentralised form of adaptation, in which individual nodes can independently select, and update their own recommendation algorithm, while still collectively contributing to the overall system's mission. %G English %Z TC 6 %Z WG 6.1 %2 https://inria.hal.science/hal-01138365v2/document %2 https://inria.hal.science/hal-01138365v2/file/similitude_dais2015.pdf %L hal-01138365 %U https://inria.hal.science/hal-01138365 %~ INSTITUT-TELECOM %~ UNIV-RENNES1 %~ CNRS %~ INRIA %~ UNIV-UBS %~ INSA-RENNES %~ INRIA-RENNES %~ IRISA %~ IRISA_SET %~ INRIA_TEST %~ TESTALAIN1 %~ IFIP-LNCS %~ IFIP %~ CENTRALESUPELEC %~ IRISA-D1 %~ INRIA2 %~ IFIP-TC %~ IFIP-WG %~ IFIP-TC6 %~ IFIP-WG6-1 %~ IFIP-DAIS %~ UR1-HAL %~ UR1-MATH-STIC %~ UR1-UFR-ISTIC %~ IFIP-DISCOTEC %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INRIA-RENGRE %~ IFIP-LNCS-9038 %~ INSTITUTS-TELECOM %~ ANR %~ UR1-MATH-NUM %~ INRIA-ROYAUMEUNI
