Enhancing Exploration with a Faceted Browser through Summarization

Abstract

An enhanced faceted browsing system has been developed to support users' exploration of large multi-tagged document collections. It provides summary measures of document result sets at each step of navigation through a set of representative terms and a diverse set of documents. These summaries are derived from pre-materialized views that allow for quick calculation of centroids for various result sets. The utility and efficiency of the system is demonstrated on the New York Times Annotated Corpus.
