Another blockmodel option is to use programs for formal concept
lattice analysis (a.k.a. "Galois lattice" analysis), such as Galicia
or Toscana (all open-source & cross-platform):
For more details on using such lattices to deal precisely with this
kind of data -- agent groups based on shared terminology -- you could
have a look at "Lattice-based dynamic and overlapping taxonomies: the
case of epistemic communities", CR, P. Bourgine, Scientometrics, 69
(2), to appear 2006. http://camille.roth.free.fr/travaux/dynamicgl.pdf
