This thesis offers a corpus-based contrastive analysis of the tense and
aspect systems of English and Spanish. The corpora employed were the Corpus
de Referencia del Español Actual (CREA) for Spanish and the British
National Corpus (BNC) for English, and the theoretical framework used in
the analysis of data was that of the Systemic-Functional Grammar. The
results of the analysis were applied to the design of linguistic resources
for the automatic generation of tense and aspect in English and Spanish
texts. These linguistic resources were developed with the grammar
development environment KPML.
