DOCUMENT SUMMARIZATION USING NOUN AND SENTENCE RANKING

摘要

Systems and methods are provided for summarization of electronic text documents. Nouns and sentences are identified in a text document, and the most-prevalent nouns are further identified based on frequency. The sentences in the document are scored based on assigning points based on cumulative presence or absence of each of the most-prevalent nouns. A tag cloud consisting of the most-prevalent nouns is displayed together with the highest-scoring sentences, thereby providing context for the nouns in the tag cloud.
