Abstract
A 'domain-general' method for topical segmentation of a document input includes the steps of: extracting one or more selected terms from a document; linking occurrences of the extracted terms based upon the proximity of similar terms; and assigning weighted scores to paragraphs of the document input corresponding to the linked occurrences. In accordance with the present invention, the values of the assigned scores depend upon the type of the selected terms, e.g., common noun, proper noun, pronominal, and the position of the linked occurrences with respect to the paragraphs, e.g., front, during, rear, etc. Upon zero-sum normalization, the assigned scores represent the boundaries of the topical segments of the document input.
