This paper presents a proposal for automatic discourse analysis of texts written in Brazilian Portuguese. The corresponding system, named DiZer, takes as input a full text and yields its rhetorical, semantic, and intentional structures. Based on corpus analysis, the underlying research is aimed at verifying the contribution of morphology, syntax, semantics, and statistics to discourse analysis.
