Social networks have emerged from niche existence
to a mass phenomenon. Nowadays, their fundamental
concepts, such as managing personal contacts and sharing
profile information, are increasingly harnessed for businesses
in professional environments. Similar to service-oriented networks,
they allow flexible discovery on demand and loose
coupling of participants. Establishing social links facilitates
cooperation and enables selective sharing of information.
Intuitively, one shares more information with his connected
neighbors and less or even none with unrelated individuals.
Today, information is one of the most important and valuable
goods in business networks. Being informed about ongoing
collaborations and upcoming trends is a key success factor.
Thus, in professional networks, participants aim at strategically
establishing connections to enable reliable information flows.
In this paper, we especially highlight an opportunistic model
that let mediators connect actually unrelated actors in order
to benefit from information mediation. We further discuss a
framework that implements this model for service-oriented
professional virtual communities.
