    Dear List members,

    Can anyone point me to a free Text Classification system?
    (More details of what I want it for below.)

    Thank you in advance for any help

    Measuring Corpus homogeneity

    My thesis project is to measure corpus homogeneity. As part of that
    project, I have developed methods for unsupervised classification of
    documents based on text internal evidence. I now want a supervised
    classification system which I can use to evaluate the unsupervised
    classification I have developed.

    To date, the corpus I used for the experiments is made of 107
    documents from the BNC (about 2 million words). The idea is to use the
    BNC Index information and part of the corpus documents to produce a
    training sample and use the rest of the corpus documents as a test
    corpus. I would like to compare the results of the unsupervised
    classification againt those from the supervised classification.
