Texplore- exploring expository texts via hierarchical representation
Yaakov Yaari · 1998
Exploring expository texts presents an interest- Jig and important ch_allenge. They are read routinely and extensively in the fore of online newspapers, web-based articles, reports, technical aud academic papers. We present a system, called Texplore, which assists readers in exploring the content of expository texts. The system provides two mech-ms for text exploration, an expandable outline that represents the hierarchical structure of the text, and a concept index, hot-linked to the concept references in the text. The hierarchical structure is discov- ered using lexical cohesion methods combined with hierarchical agglomerative clustering. The list of concepts are discovered by n-gram analysis filtered by part-of-speech patterns. Rather than the common presentation of documents by static abstracts, Texplore provides dynamic presentation of the text's content, where the user controls the level of details.
