Multidocument Summarization with GISTexter

Proceedings of the Third International Conference on Language Resources and Evaluation (LREC 2002)

Abstract

This paper presents the architecture and the multidocument summarization techniques implemented in the GISTEXTER system. The paper presents an algorithm for producing incremental multi-document summaries if extraction templates of good quality are available. An empirical method of generating ad-hoc templates that can be populated with information extracted from texts by automatically acquired extraction patterns is also presented. The results of GISTEXTER in the DUC-2001 evaluations account for the advantages of using the techniques presented in this paper.
