Los corpus diacrónicos como instrumento para el estudio del origen y distribución de la concordancia de objeto en español

The article is based on previous research on the genesis and diffusion of object agreement in Spanish, which highlights the advantages of a corpus-driven approach as contrasted with other lines of analysis. We take into account the Spanish historical corpora available and discuss the feasibility of retrieving the necessary data for this type of study. Furthermore, we put forward some proposals about what kind of information (tagging, parsing, etc.) could make the task easier. Lastly, in the light of corpus data, we can see to what extent certain syntactic functions favour particular coding devices and information status, and consider if the various discourse genres registered in the history of the Spanish language are equally representative of these preferences.
