Towards Interactive Information Access based on Document Structures

Abstract

A framework is examined, in which the users interactively access documents, like scientific papers, with a physical structure appearing in the layout and a logical structure based on their contents. It supports effective and flexible use of the documents by allowing the users to retrieve relevant logical units through specification of their contents and/or roles in the document, and to browse those units and their contexts by strolling across both logical and physical structures. The whole framework and a method of document analysis that reconstructs the logical structure of a document and constructs its representation are mainly discussed in this paper.
