Suffixal and Prefixal Morpholexical Relationships of the Spanish

This work is about derivational suffixes, endings and prefixes of the Spanish language, which are useful for the establishment of about 70 000 suffixal and 11 000 prefixal extended morpholexical relationships deduced from a corpus of 134 109 canonical forms. A computational tool is developed capable of solving and answering to any morphological aspect of a Spanish word. The tool encompasses everything related with derivation, prefixation and other nearby aspects. It allows the recognition, the generation and the manipulation of morpholexical relationships of any word and of its related words, includes the recovery of all its lexicogenetical information until arriving at a primitive, the management and the control of the affixes in the treatment of its relationships, as well as the regularity in the established relationship.

The Spanish morphology in internet

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.

Morphoanalysis of Spanish texts: two applications for web pages

The applications described here follow up the works performed in the recent last years by the Data Structures and Computational Linguistics Group at Las Palmas de Gran Canaria University. These works have been developed about computational Linguistics and, as one of their results, some tools for morphologic identification and generation have been released. This work presents the use of those tools as parts of new applications designed to benefit from the great linguistic information flow from Internet. Two kinds of applications are identified, both according to the interactive grade of the linguistics studies to be done, and two prototypes, named DAWeb and NAWeb, are developed with special attention to their architecture in order to maximize the efficiency of both. Analysis modes include: neologism detection, word use (qualitative and quantitative measurements) and some syntax aspects like lexical collocations or prepositional regimes.

Análisis lingüístico y formalización computacional del texto argumentativo (OpinionText TIP)

En algunas ocasiones, el hablante que interviene activamente y de forma escrita en el debate politico y social que tiene lugar en la Red provoca un acto comunicativo fallido, al dar prioridad a su deseo de expresarse sin prestar atencion a los parametros linguisticos y discursivos que dotan de eficacia a estos intercambios. El trabajo que presentamos pretende contribuir a la mejora de las estrategias de comunicacion de los actores sociales. Para ello, desarrollaremos un analisis teorico y aplicado de las estrategias linguisticas y comunicativas definitorias de la argumentacion, que haga posible el diseno y desarrollo de una herramienta informatica, OpinionText TIP, con la que el usuario pueda llevar a cabo un analisis de su propia produccion argumentativa basandose en parametros objetivables y mensurables, de modo que aumenten las posibilidades de que su texto logre la adhesion de sus lectores.
