Supporting Peer-to-Peer User Communities Julita Vassileva   View Paper (PDF)   Return to P2P and Ubiquitous Abstract The paper describes a design of a peer-to-peer system which is being developed currently to support file and service (help, advise) sharing in research groups and groups of learners. The design addresses some non-technical problems in the deployment of P2P systems, such as coping with free riders, creating closely-knit groups of users sharing common interests and trust. It describes a user modelling approach for servents and presents several approaches for motivating users to participate and contribute to the community.
