1. A system of automatically discovering terms in a document that are relevant to a given target topic, comprising:

  • a new terms discoverer for identifying the terms in the document;

    a candidate terms discoverer for identifying potentially relevant terms from the terms identified by the new terms discoverer;

    the candidate terms discoverer comprising;

    an association module that performs a statistical analysis, regardless of an occurrence frequency of the terms within a single document; and

    a filtering module that filters association rules with relevance that surpasses a user specified threshold; and

    a relevant terms discoverer that identifies relevant terms by applying the association rules to the potentially relevant terms identified by the candidate terms discoverer, to refine a relevance of the potentially relevant terms by filtering false relevance.
