The present paper is focused on the study of those relations that auxiliary verbs can establish among themselves when chained in a sequence. Regarding those sequences, which in Spanish can be considerably long, the literature has displayed primarily interest in formulating a set of principles that can predict possible relative orderings among auxiliaries. On the contrary, our paper delves into a less walked path: the description of relations established within an auxiliary chain. We will start from the traditional definition of auxiliary verb as a unit that modifies the ‘main’ or ‘lexical’ verb, and proceed to show that such a conception makes the wrong predictions when it comes to explain those internal relations, for it only accounts for a subset of the cases. This explanatory problem is common to both traditional and more formal models. In our opinion, the distinction between between <em>lexical </em>and <em>functional</em> auxiliaries that we propose in this work, in the context of a dynamic computational model that includes and derives this distinction, allows us to overcome these shortcomings of traditional analyses.

This paper is concerno! with the problem of obtaining a procedure for the automatic generation oftexts, inside a defined domain. In the case of study the domain is composed of sentences which result from a Spanish morphological analysis. One important difficulty in order to develop the automatic generation of texis system is to prepare the input data. In the present work the domain is a group of simple results of morphological analysis in natural language. Input data redundancy has been eliminatcd from such group, the essential information has been extracted and the logical struclurc has been obtained. The possibility to say the same in different ways forces to select the lexicón, to observe the context and to reinforce the control by means of selection criteria with the aim of assuring that the obtained text is correct and formal, objective and concise. The main contribution of this work consists in converting the logical structure into a sentence which represente the information in a cohesive, coherent, comprehensible way and with certain style. IntroducciónDebido a que una de las principales dificultades a la hora de desarrollar la generación automática de textos se halla en la necesidad de preparar los datos de entrada, el presente trabajo modela el espacio de aplicación a partir de un conjunto de resultados simples de análisis morfológico en lenguaje natural, del que se ha eliminado toda redundancia para extraer su información esencial y obtener la estructura lógica de tal información -fase de análisis.La producción textual estudia su obtención automática a partir de la representación interna de la información -fase de generación. La principal aportación de este trabajo radica en pasar de esa estructura lógica a una frase variable -planificada en un único dominio limitado-con la que representar la información de forma cohesionada, coherente, comprensible y con cierto estilo. La posibilidad de decir lo mismo de diferentes formas obliga a seleccionar el léxico, a observar el contexto y a reforzar el control mediante criterios de selección para asegurar que el texto obtenido sea correcto y resulte formal, objetivo y escueto. 245

Resumo: O triunfo electoral do Frente Amplio (FA) uruguaio en outubro de 2004 representaba en aparencia unha ruptura con toda a política económica seguida ata aquela e que desembocou entre os anos 1999 e 2002 nunha grave crise económica. Neste artigo analízase o proceso iniciado coas reformas do FA, partindo da evolución da estrutura produtiva do país, dos cambios na distribución primaria da renda e, finalmente, da distribución secundaria e da pobreza. O traballo conclúe que, en termos de política social, a ruptura foi real e tivo lugar unha importante redución da desigualdade. Porén, e a pesar de recoñecer as limitacións derivadas dun período de análise aínda necesariamente pouco prolongado, os cambios na estrutura produtiva foron menores, o que pon en risco os logros anteriores ante conxunturas económicas menos propicias que as actuais. Palabras clave: Estrutura produtiva / Ciclo político / Desigualdade / Abstract: The electoral victory of the Frente Amplio (FA) in Uruguay in October, 2004, apparently represented a break with the economic policies that had been implemented till then. Those policies were indeed the same that lead the country to its deepest economic crisis between 1999 and 2002. In this article, we analyse the process triggered by those reforms, considering the evolution of the economic structure, the changes in the primary distribution of income and finally the impact on the secondary distribution of income and on poverty. We conclude that the break has been more than apparent in terms of social policies, reducing thereby inequality. However, and although we acknowledge that the span of time is still not too long, we conclude also that the changes in the productive structure are much weaker, thus jeopardizing the previous achievements when faced with worse economic conditions.
