L'utilisation de schémas de discours pour améliorer la pertinence et la cohérence discursive dans le cadre du résumé automatique de blogs

Shamima Mithun, Leila Kosseim
2012 Document Numérique  
To address these two issues, we propose a domain-independent query-based summarization approach for opinionated documents that uses intra-sentential discourse structures in the framework of schemata.  ...  Finally post-schema heuristics that work at the inter-sentence level are used to improve coherence further.  ...  Opinion (sentiment) information is typically used to rank blog sentences for summarization, but this task can possibly add more noise to the blog sentence ranking process if not done properly.  ...

Dimensions of Argumentation in Social Media [chapter]

Jodi Schneider, Brian Davis, Adam Wyner
