A methodology for the enhancement of a hypertext version of a textbook by the automatic insertion of links in the subject index

This paper presents a methodology for the enhancement of a hypertext version of a textbook. The enhancement over the textual version of the textbook is achieved by automatically inserting links between text excerpts of the textbook and the item in the subject index produced by the author of the textbook. These links enable access to parts of the textbook that have not been specifically indexed by the author, but that are semantically related to items in the subject index. Such links are meant to improve the effectiveness of the use of the book in search oriented tasks
