ABSTRACT:
A summary is automatically formed by selecting regions of a document. Each selected region includes at least two members of a seed list. The seed list is formed from a predetermined number of the most frequently occurring complex expressions in the document that are not on a stop list. If the summary is too long, the region-selection process is performed on the summary to produce a shorter summary. This region-selection process is repeated until a summary is produced having a desired length. Each time the region selection process is repeated, the seed list members are added to the stop list and the complexity level used to identify frequently occurring expressions is reduced.
