Summarizing through sense concentration and Contextual Exploration rules: the CHORAL system at TAC 2009
نویسندگان
چکیده
This paper presents LIC2M’s second participation in TAC evaluation campaign (Update Summarization task). Two runs were submitted: simple summarization through sense concentration and combined summarization through sense concentration and Contextual Exploration rules. The sense concentration feature is based on the unsupervised recognition of word senses from a large corpus. Contextual Exploration feature is based on journalistic discourse analysis, which results on a set of rules in order to annotate meaningful sentences in press releases.

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 کاملSummarizing with Roget's and with FrameNet
We submitted runs from two different systems for the update summary task at TAC 2009. The first system refined its use of Roget’s Thesaurus, moving beyond 2008’s semantic relatedness to compute an entropy-based uniqueness measure, with improved results in summary construction. The other system, our first use of deeper semantic knowledge, represents sentences as FrameNet types in a conceptual gr...

متن کاملImproving Search and Rescue Using Contextual Information
Search and rescue (SAR) is a challenging application for autonomous robotics research. The requirements of this kind of application are very demanding and are still far from being met. One of the most compelling requirements is the capability of robots to adapt their functionalities to harsh and heterogeneous environments. In order to meet this requirement, it is common to embed contextual know...
