- Weeks, 2001. Understanding Trust Management
Systems. Crucial paper for understanding much recent work on
trust-metrics. Presents framework, motivates it with examples, and shows
be modelled using it.
- Carbone, Nielsen and Sassone, 2003. A Formal Model
for Trust in Dynamic Networks.. Proposes a simple domain-
theoretic formalisation of what a model of trust is that provides the basis for
some significant later work.
- Twigg and Dimmock, 2003. Attack-Resistance of Computational
Trust Models. Synthetic exposition of several trust-metrics that
have some degree of attack resistance. Good exposition of Raph's metric,
gives alternate proof of attack resistance by order-theoretic reasoning.
- Moreton and Twigg, 2003. Trading in Trust, Tokens, and Stamps. Proposes system
adding trust trading to trust-metrics by stamps, and argues for advantages
this system. Interesting for Advogato: could provide a more principled
means of bringing in new members than just rejigging weights.
- Ziegler and Lausen, 2005. Propagation Models for Trust
and Distrust in Social Networks. Motivates criteria for success of
trust-metrics when applied to social networks, including attack resistance.
Proposes a new algorithm, which they call Appleseed and which is
based on the spreading activation technique, which they
compare to Raph's version. This work is based in part on Ziegler's PhD thesis,
Decentralized Recommender Systems.
I'm curious as to the origin of Raph's talk of "good", "bad", and "confused"
nodes. Is it his novel usage, or did he get it from elsewhere?
I'm amused also to read references sections that cite
trust -metrics thesis as if it was a successfully defended one. Folks who run
the thesis he did write will no doubt conclude he is one of the select few who
wrote two PhDs concurrently...
