Integration of an XML electronic dictionary with linguistic tools for natural language processing

This study proposes the codification of lexical information in electronic dictionaries, in accordance with a generic and extendable XML scheme model, and its conjunction with linguistic tools for the processing of natural language. Our approach is different from other similar studies in that we propose XML coding of those items from a dictionary of meanings that are less related to the lexical units. Linguistic information, such as morphology, syllables, phonology, etc., will be included by means of specific linguistic tools. The use of XML as a container for the information allows the use of other XML tools for carrying out searches or for enabling presentation of the information in different resources. This model is particularly important as it combines two parallel paradigms-extendable labelling of documents and computational linguistics-and it is also applicable to other languages. We have included a comparison with the labelling proposal of printed dictionaries carried out by the Text Encoding Initiative (TEI). The proposed design has been validated with a dictionary of more than 145000 accepted meanings.

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.
