Synthèse de flux de messages en temps réel

Monitoring stream of social media posts has attracted significant attention in the last view years. Real time summarization in microblog aims at providing new relevant and non redundant information about an event as soon as it occurs. In this paper, we propose a novel continuous summarization approach in which information updates are pushed in real time. The decision to select/ignore incoming information is based on its informativeness and redundancy scores. The on-hand post is added to a summary only if the aforementioned scores are above a parametric free threshold. Our strategy was evaluated on a TREC Temporal Summarization 2014 data-set and it was compared with a well known baselines. The results reveal that our method outperforms all baselines and runs of the aforementioned task. The generated summaries are shorter and have higher precision than summaries generated by the baselines. MOTS-CLÉS : filtrage temps réel, résumé temporal, informativité, redondance,
