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
. I am also wondering if the techniques you describe could be applied
to "subjective logic" , which some folks are looking at as a way to
quantify and compose trust.
(I have a slightly later version dated Jan 2001 but an unable to find
a URL for it.)
