Resumen:
Spanish unstressed pronouns, also known as clitics in the generative grammar literature, constitute a domain of morphological, syntactic and semantic phenomena thoroughly studied from the perspective of both formal and functional approaches to the study of language. Despite this coverage, there are still gaps which deserve our attention, particularly from the viewpoint of Computational Linguistics. Thus, for example, Castel (1994: Ch. V) is a formalization of Perlmutter (1971)’s generalization Se II I III on Spanish clitics word order in terms of a unification categorial grammar (Zeevat et al. 1987). However, since the resulting grammar is not implemented computationally, it is very difficult, if not impossible, to evaluate the consequences of the account. In this paper, I purport to remedy this limitation by redefining River Plate Spanish clitics in the framework of OpenCCG (Bozºahin et al. 2006), which is an (open source) computational implementation of Combinatory Categorial Grammar (Steedman 2000). The constraint Se II I III is here decomposed into feature configurations reflecting clitic co-ocurrence restrictions. Clitics, in turn, are lexically specified as functors of type S<1>$1/(S<2>$1|NP), where the feature structure of S<2> contains the relevant co-ocurrence restrictions which define the combinatory potential of a given clitic.clitics in the generative grammar literature, constitute a domain of morphological, syntactic and semantic phenomena thoroughly studied from the perspective of both formal and functional approaches to the study of language.
