Towards a unified approach to modality annotation in portuguese

Abstract: This paper introduces the first efforts towards a common ground for modality annotation for Portuguese. We take into account two existing schemes for European and Brazilian Portuguese, already implemented to written texts, and to spontaneous speech data, respectively. We compare the two schemes, discuss their strengths and weaknesses, and, then, introduce our unifying proposal, pointing out the issues which seem to be already pacified and points that should be considered when the scheme starts to be implemented.
