1. A computer-implemented method for summarizing documents, comprising the following steps:

  • counting how frequently content words appear in a document;

    scoring individual sentences according to their respective content words, wherein sentences which contain more content words that appear more frequently in the document are ranked higher than sentences which contain fewer high-frequency content words and than sentences which contain content words that appear less frequently in the document;

    performing a cue-phrase analysis by comparing words and phrases in the sentences with a pre-compiled list of words and phrases and setting conditions on use of sentences that contain any words or phrases on the list; and

    creating a summary which contains higher ranked sentences and which may include conditioned sentences in an event that the conditions are satisfied.
