I must have missed your query regarding this topic, but you might wish to
look at a paper I wrote with Bruce Croft at SIGIR 1999 about concept
hierarchies, essentially automatic generation of hierarchical thesauri.
Also I did some work with a student of mine called Hideo Joho, who worked
on Marti Hearst's ideas, that work was published in ACM CIKM 2000 and a
poster in the HLT 2001 conference that is somewhat related.
Bruce Croft has a PhD student who is working on aspect of the concept
hierarchies, I think she had a paper at SIGIR 2001, her name is Dawn Lawrie.
