The SenSem Corpus: an annotated corpus for Spanish and Catalan with information about aspectuality, modality, polarity and factuality

Abstract In this paper, we present the annotation scheme used in the SenSem corpora (SSC), for Spanish and Catalan, to codify information regarding aspectuality, modality, polarity and factuality. As regards aspectuality, the most relevant contribution is the codification of information about dynamicity, telicity and iterativity. Regarding factuality, we present a more fine-grained annotation of uncertainty as applied to the identification of impossible events, completely uncertain events and neutral uncertain events. Although information about factuality in Spanish has been provided elsewhere, the Catalan SSC is the only corpus to do so for Catalan.
