Microsoft Research at DUC2006: Task-Focused Summarization with Sentence Simplification and Lexical Expansion
نویسندگان
چکیده
Our DUC2006 system comprised three main components: a task-focused extractive summarization system, sentence simplification, and lexical expansion of topic words. This paper details each of these components, together with experiments designed to quantify their individual contributions. We include an analysis of our results according to two independent human evaluation methods, the NIST evaluation and the Pyramid evaluation. Our system ranked first in terms of both overall mean score and averaged per-cluster mean ranking out of 22 systems in the Pyramid evaluation, and ranked third out of 35 systems in NIST content responsiveness.

Beyond SumBasic: Task-focused summarization with sentence simplification and lexical expansion
In recent years, there has been increased interest in topic-focused multi-document summarization. In this task, automatic summaries are produced in response to a specific information request, or topic, stated by the user. The system we have designed to accomplish this task comprises four main components: a generic extractive summarization system, a topic-focusing component, sentence simplificat...

متن کاملOn the Effectiveness of using Sentence Compression Models for Query-Focused Multi-Document Summarization
This paper applies sentence compression models for the task of query-focused multi-document summarization in order to investigate if sentence compression improves the overall summarization performance. Both compression and summarization are considered as global optimization problems and solved using integer linear programming (ILP). Three different models are built depending on the order in whi...
