[rdfweb-dev] Paper on Trust Networks on the Semantic Web from MINDSWAP

[Graham Klyne]

Nice paper -- it's useful to find a range of references to work underlying 
the FOAF idea documented, and a number of other interesting references.

My one issue is the trust metric: there's no evidence I can see that this 
corresponds to actual measures of trust as applied by people. I guess 
that's ultimately a tricky area for social science research; I find I am 
wary of any approach that attempts to reduce trust to a simple scalar 
metric, as that implies a total ordering, which I don't think is the 
case. I think these issues are somewhat acknowledged in your suggestions 
for further work.

There's a lot of trust-related work from Morris Sloman's group at Imperial 
College, London. In particular, a useful survey paper they have done at 
[1]. I am also wondering if the techniques you describe could be applied 
to "subjective logic" [2], which some folks are looking at as a way to 
quantify and compose trust.
