Distributed PeCo-Mediator: finding partners via personal connections

In this paper, we describe the distributed PeCo-Mediator which supports a user to find a partner by using personal connections (PeCo). We have already proposed the PeCo-Mediator which allows members to share and use their PeCo. PeCo-Mediator is very practical for use in some small groups. However, in an organizational use there are some problems: (1) the user are reluctant to offer his/her personal details because they are private information; (2) since this system only supports the user in finding candidate partners, the user has to negotiate with them using the connection offered. Distributed PeCo-Mediator has two sub-systems: a PeCo-Collector for maintaining the individual PeCo in his/her own site, and a PeCo-Agent for supporting the negotiation between his/her and the candidate. It improves the privacy of users and also facilitates to find a cooperative and capable partner
