    That is very interesting, and, well, sad: it does not take too much of one's
    time to read work of people who are supposed to be specialist on language(s)
    , but people from one camp do not seem to care for the other camp.
    The paper of the two scholars is available at
    http://www.arxiv.org/abs/cs.CL/0412098, they say modestly in the abstract
    that" The approach is novel in its unrestricted problem domain, simplicity
    of implementation, and manifestly ontological underpinnings.". The last
    statement is even more interesting in that one of the authors, Rudi
    CilibrasiI, says in the answer to a blog: "There have been several
    philosopher's interested in this research. Somebody else mentioned Derrida
    too. I must confess my philosophical background is weak and I just now tried
    to look up Derrida on the Wikipedia.:
    http://www.magnificentwreckage.com/mt/weblog/archives/2005/03/google_as_an_a
    r.html
    There is something deeply wrong...
    I had a look at the references in the paper, and you cannot say they did not
    refer to linguistic literature (or what they take to be linguistic
    literature): there is a reference to a note on corpora in The Economist.
    Did I say something seems to be wrong?
    Best wishes,
