"Galois lattice" analysis), such as Galicia or Toscana (all open-source & cross-platform): Toscana: http://toscanaj.sourceforge.net/ Galicia: http://www.iro.umontreal.ca/~galicia/ 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.
