    Any of the following references are excellent sources on this:

    @Book{Oakes:1998:SCL,
      author = {Oakes, Michael P.},
      title = {Statistics for Corpus Linguistics},
      publisher = {Edinburgh University Press},
      year = {1998},
      isbn = {0748608176}
    }

    @Book{Manning:1999:FSN,
      author = {Christopher D. Manning and Hinrich Sch\"utze},
      title = {Foundations of Statistical Natural Language Processing},

    }

    To briefly quote from Charniak, p. 122:

    "The t-score is a standard is a standard test to see if the results
    could be expected on the basis of chance."
