The TITech Summarization System at TAC-2009

چکیده
This paper presents the TITech summarization system participating in TAC2009. Specifically, we discuss our results for the Update track. We propose a new method for creating summaries by ordering sentences. After a draft summary is obtained, we conduct agglomerative hierarchical clustering on the sentences of the draft summary based on sentence associativity. Then we use a probabilistic method to adjust the order of these draft summaries. We submitted two runs: the results that sentence order is decided by utilizing chronological information, and the results of our proposed method.

Description of the LIPN Systems at TAC2009
The Text Analysis Conferences (TAC) offer a unique occasion to show innovative approaches to text summarization. As a first incursion into this new research area, LIPN participated in the Update Summarization task of TAC 2008. The LIPN wanted to improve the results obtained during TAC 2008 and to confirm that the changes made to its summarization system really enhanced the quality of the automa...

In this paper, we presents the results obtained by using a probabilistic summarization framework for the TAC 2009 update summarization task, which has the merits of combining the sentence generative probability and the sentence prior probability for sentence ranking systematically. Especially, each sentence of a document to be summarized is treated as a probabilistic generative model for predic...

This paper presents our extractive summarization systems at the update summarization track of TAC 2009. This system is based on our newly developed document summarization framework under the theory of conditional information distance among many objects. The best summary is defined in this paper to be the one which has the minimum information distance to the entire document set. The best update ...
متن کاملObtaining Uncertainty to Generate Summarization
This paper describes Huazhong Normal University’s participation in TAC 2010. For the guided summarization task, we use a better basic summarization system which makes many improvements to the method we used in TAC 2009. Our system is based on uncertainty methods, including cloud. Our teams IDs are 6 and 23, and they are among the best of all the 43 automatic summarization systems in TAC 2010.
متن کاملThe ICSI/UTD Summarization System at TAC 2009
We describe improvements to our 2008 system that result in a top-performing summarization system. The motivating ideas are (1) improve sentence boundary detection to avoid damaging errors in preprocessing; (2) prune sentences that are unlikely to work well in a summary; (3) leverage sentence position to improve update summarization; (4) focus on high-precision sentence compression to improve re...
