A Symbolic Summarizer with 2 Steps of Sentence Selection for TAC 2009
نویسندگان
چکیده
RALI developed the system NESS2 for the TAC 2009 summarization task, with the main goal of testing the hypothesis that performing sentence selection in 2 steps improves the quality of the created summaries. The first step selects a number of top sentences, while the second step selects the best combination of the top scored sentences. We use the same small number of linguistic criteria to perform both evaluation steps. The two runs of NESS2, run IDs 8 and 10, ranked well in the competition, especially in linguistic quality and overall responsiveness, and the results show that the second step of sentence selection improves the performance of the system.

Sentence Position revisited: A robust light-weight Update Summarization baseline Algorithm
In this paper, we describe a sentence position based summarizer that is built based on a sentence position policy, created from the evaluation testbed of recent summarization tasks at Document Understanding Conferences (DUC). We show that the summarizer thus built is able to outperform most systems participating in task focused summarization evaluations at Text Analysis Conferences (TAC) 2008. ...

This paper deals with our past and recent research in text summarization. We went from single-document summarization through multidocument summarization to update summarization. We describe the development of our summarizer which is based on latent semantic analysis (LSA). The classical LSA-based summarization model was improved by Iterative Residual Rescaling. We propose the update summarizati...

The paper describes our participation in the Guided and Multilingual Summarization Tasks at the Text Analysis Conference 2011 (TAC’11). We participated in the Guided task with the system from the previous year which combines aspect identification by an event extraction system and automatically learned lexicons with LSA-based summarizer. This year we included temporal analysis to improve sentenc...
متن کاملA Symbolic Summarizer for the Update Task of TAC 2008
NESS, RALI’s summarization system for the TAC 2008’s update task, brings improvements and continuation to our last year’s “all-symbolic” approach. The most distinctive feature of our system is to rely on the syntactical parser FIPS to extract linguistic knowledge from source documents. NESS selects sentences based on linguistic metrics, especially tf · idf scores that measure the relevance of t...
متن کاملThe LIA Update Summarization Systems at TAC 2008 (DRAFT)
For the third participation of the LIA to the DUC–TAC conferences, two summarizers were developed. The first is based on the SMMR sentence scoring algorithm described in (Boudin et al., 2008). The second summarizer is a fusion between two sentence scoring methods: SMMR and a variable length insertion gap n-term model (Favre et al., 2006; Boudin et al., 2007). We compare our two summarizers usin...
