Towards Topic Driven Access to Full Text Documents

摘要

We address the issue of providing topic driven access to full text documents. The methodology we propose is a combination of topic segmentation and information retrieval techniques. By segmenting the text into topic driven segments, we obtain small and coherent documents that can be used in two ways: as a basis for automatically generating hypertext links, and as a visualization aid for the reader who is presented with a small set of focused and restricted text snippets. In the presence of a concept hierarchy, or ontology, information retrieval techniques can be used to connect the segments obtained to concepts in the ontology. In this paper we concentrate on the text segmentation phase: we describe our approach to segmentation, discuss issues related to evaluation, and report on preliminary results.
