Títol A New Lexical Chain Algorithm Used for Automatic Summarization

Ponent Edgar Gonzàlez

Lloc Omega-S208

Dia 19 Octubre 2009

Horari 10:00h - Café

10:15h - Presentació

Abstract Lexical chains are widely used as a representation of text for Natural Language Processing tasks. However, efficient algorithms for the construction of lexical chains often resort to local decisions. We propose a new algorithm for Lexical Chaining, based on a global function optimization through Relaxation Labelling. A preliminary evaluation of the performance of our approach has been performed on a Catalan agency news corpus. The comparison to an efficient state-of-the-art algorithm for Lexical Chaining gives promising results. The resulting lexical chainer has been used for a complete multilingual Automatic Summarization system, available on-line

 

Es tracta d'un assaig de la presentació que l'Edgar farà uns dies després al CCIA 2009.
