Resumo


This paper describes how discursive knowledge, given by the discursive theories RST (Rhetorical Structure Theory) and CST (Cross-document Structure Theory), may improve the automatic evaluation of local coherence in multi-document summaries. Two of the main coherence models from literature were incremented with discursive information and obtained 91.3% of accuracy, with a gain of 53% in relation to the original results.
