Abstract

This paper presents a formalization of rules on plural formation in Spanish to be used in the processing of specialized terminology, as it is frequently the case that terms are not found in dictionaries of general language and therefore they cannot be lemmatized or POS-tagged. The absence of terms in general dictionaries has negative effects in tasks such as terminology extraction, particularly in the case of morphologically rich languages. We attack the problem by cascading through multiple trasnfser rules, regular expressions and lexical aquisition from large corpora. Results show significant reduction of the error rate of two POS-taggers: TreeTagger and UDPipe. We offer an open-source implementation which works as a post-process, cleaning up after the tagger.
