    Dear List Members,

    Does anbyody know of attempts to automatically build hierarchical thesauri
    from larga corpora using unsupervised or only minimally supervised methods?
    Most of the work around concentrates on finding related terms (e.g., using
    various clustering algorithms), but apparently there hasn't been much work
    on building hierarchical thesauri, with (at least) the RT, BT and NT
    relations and with all nodes in the hierarchy corresponding to meaningful
    descriptors. Any pointers?

    Thanks in advance,

           Adam P.
