Abstract
A system for generating and displaying point of view and generic gists for use in a document browsing system. Each point of view gist provides a synopsis or abstract that reflects the content of a document from a predetermined point of view or slant. A content processing system analyzes documents to generate a thematic profile for use by the point of view gist processing. The point of view gist processing generates point of view gists based on the different themes or topics contained in a document by identifying paragraphs from the document that include content relating to a theme for which the point of view gist is based. In one embodiment, the user of a document browsing system inputs topics to select a particular point of view gist for a document. A document browsing system may also display point of view gists based on a navigation history of categories selected by a user though use of a document browsing system. In another embodiment, a document browsing system generates and displays generic gists, which include content relating to the document themes.
