A Query-Focused Multi-Document Summarizer Based on Lexical Chains

By Jing Li, Le Sun, Chunyu Kit and Jonathan Webster


This paper presents our work on queryfocused multi-document summarization with the enhanced IS_SUM system. We focus on improving its lexical chain algorithm for efficiency enhancement, applying the WordNet for similarity calculation and adapting it to query-focused multi-document summarization. We present its performance in terms of its official DUC2007 evaluation results together with some other improvements.
