  12. Conclusions and future works • We have developed a P2P application (based on JXTA protocols) for DKM that provides functionalities such as: • Seeker • Provider • Broker • Federations management • To be developed: • Community Management: peers can suggest to users to which federations they should join since semantically similar to them (bottom up community formation) • Push information services: peers can advertise services to other peers on the base of semantically relevant interests (targeted advertisement) • Recommendation: peers can listen to other users or other peers requests and suggest where or what to look for (help new comers) • Social Network Monitoring: Knowledge Managers can monitor the formation and evolution of trust networks and corporate languages
