Abstract
In a novel approach for retrieving information a set of sub-documents first is established based upon a set of documents. A query is processed which operates on the set of sub-documents, causing a score to be generated for each sub-document. The score for each sub-document is indicative of the relevance of the corresponding sub-document to the query. The scores are reviewed and the best sub-document is retrieved. According to one aspect of the invention, the best sub-document has a score that indicates the highest relevance between the sub-document and the query. According to another aspect of the invention, in response to a user selection, the next best sub-document is identified and retrieved. The sub-documents are also presented to the user in an order based upon the scores. According to another aspect of the invention, the document containing the sub-document having the best score is displayed and automatically scrolled to the location of the sub-document having the best score. Based upon user input, the document is automatically scrolled to the location containing the next best sub-document. If the next best sub-document is contained in another document, that document is automatically loaded.
