In this paper we present the development of a text simplification system for Spanish. Text simplification is the adaptation of a text for the special needs of certain groups of readers, such as language learners, people with cognitive difficulties, and elderly people, among others. There is a clear need for simplified texts, but manual production and adaptation of existing text is labour-intensive and costly. Automatic simplification is a field which attracts growing attention in Natural Language Processing, but, to the best of our knowledge, there are no existing simplification tools for Spanish. We present a corpus study which aims to identify the operations a text simplification system needs to carry out in order to produce an output similar to what human editors produce when they simplify news texts. We also present a first prototype for automatic simplification, which shows that the most important simplification operations can be successfully treated. [ABSTRACT FROM AUTHOR]

Grammar studies have focused lately on speech instead of on written language, being the latter the most traditional approach. This situation confronts us with the necessity of a new definition for some grammar concepts. This paper proposes a new definition for the concept of sentence so that it can be used for spoken Spanish analysis. Already existing definitions are evaluated and discarded because they do not fit with many normal speech structures. Besides, they usually are confusing regarding syntactic, prosodic and pragmatic features. We propose a new definition only based on grammar and semantic features. Conclusions show that this approach allows the syntactic analysis of speech in a much more accurate way. [ABSTRACT FROM AUTHOR]

Abstract: Since the comparative work by , we know that similar information packagings may resort to completely different formal mechanisms across languages. For instance, right-dislocation (RD) is a highly productive backgrounding strategy in Catalan, but a marginal one in English, resorting in stress shift. To our current understanding, one might take this situation to be a casual state of affairs, or rather, one may raise the stronger hypothesis that understandable and definable factors exist underlying crosslinguistic variation at the syntax/information structure interface. This enterprise has been partially pursued for typologically distant languages (e.g. Catalan vs. English vs. Finnish vs. Turkish), but unlike much recent work in syntax () very little or no attention has been paid to a microparametric comparative point. Crucially, a finer-grained comparison of closely related languages may shed light on the current hypotheses concerning the syntax/information structure interface. In this paper I will pursue this task, concentrating on the role of RD in two genetically related Romance languages: Catalan, and Spanish. My first goal is to quantify the degree of productivity of RD in these two kindred languages through a corpus based analysis. The second goal is to determine the range of formal mechanisms that Spanish resorts to in order to fulfil the discourse roles typically associated with RD in Catalan. Finally, my third goal will consist of putting forward a hypothesis to explain the factors that determine the quite different discourse management of the formal mechanisms available in these two languages.
