This Web service tags morpholexically any Spanish word and it gets the corresponding forms starting from a canonical form and from the flexion asked for. In the verbs, it deals with the simple and compound conjugation, the enclitic pronouns, the flexion of the participle like verbal adjective and the diminutive of the gerund. With the nonverbal forms, this web service considers: gender and number, heteronomy for change of sex, superlative degree, adverbiation and the appreciative derivation. In the tag and in the generation the prefixation is taken into account. It allows the manipulation of morpholexical relationships. It offers a global vision of the behavior and productivity of the Spanish words in the principal processes of formation (sufixation, prefixation, parasinthesis, suppression, regression, zero-modification, apocopation, metathesis and others which are unclassifiable and that generate alternative graphical forms). It includes the principal Spanish lexicographic repertoires. It considers 151103 canonical forms that produce more than 4900000 flexioned and derived forms and about 90000 morpholexical relationships are established.

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
