D-STAG : a discourse analysis formalism based on synchronous TAGs D-STAG : un formalisme d'analyse automatique de discours fondé sur les TAG synchrones

We propose D-STAG, a new formalism for the automatic analysis of the discourse structure of texts. The analyses computed by D-STAG are hierarchical discourse structures annotated with discourse relations, that are compatible with discourse structures computed in SDRT. The discourse analysis extends the sententiall analysis, without modifying it, which makes conceivable the realization of a discourse analyzer.
