Abstract:
A peer-to-peer (P2p) trust framework is being developed
that takes into account not only directly verifiable information,
but also, as its new contribution, information that could
be regarded as word-of-mouth advertising or hearsay. By supplying
this sort of information, it is intended to both broaden
the available knowledge of nodes at the fringes of the networks
- i.e. not-highly connected entities, such as a casual online
shopper - and explicitly expand existing trust models to further
mimic real-life social behavior. Furthermore, dynamic effects
of complex networks in the dissemination of reputation information
for trust-decision making in social networks are leveraged.
A formalization for the inclusion of so-called 'weak reputation'
is presented, and prototypically implemented through
the use of fuzzy logic mechanisms. Preliminary simulation results
showing the general practicability of the concept are presented.
