This dissertation purposes to answer the question of whether or not the verb system of Black English in Dallas has the same features as those that characterize Black English in other sections of the country. Specifically, it describes in detail the use of the verb "be" within the speech of blacks in the Dallas metropolitan area and accounts for these usages formally within the framework of a transformational-generative grammar of the type proposed by Noam Chomsky.

Neste estudo apresentamos as origens da Programação Neurolingüística (PNL), seus principais fundamentos, pressupostos teóricos e objetivos; analisamos o “metamodelo”, sua relação com a linguagem e sua exploração por meio do processo de “modelagem”, a partir do enfoque presente na obra A estrutura da magia I: um livro sobre linguagem e terapia, de Richard Bandler e John Grinder, idealizadores da PNL. Examinamos as transformações obtidas mediante o processo de derivação, com base na Gramática Gerativo-Transformacional de Noam Chomsky, objetivando verificar sua relação com o “metamodelo”. Explorando o discurso do Sujeito submetido ao processo de “modelagem”, verificamos em que medida os novos conteúdos semânticos revelados pelas transformações poderiam influenciá-lo, a ponto de mudar sua visão de mundo. Para esta análise, investigamos ainda as teorias clássicas da Argumentação, em especial os conceitos de convicção e persuasão, constatando que a “modelagem” oferece ao Sujeito recursos para ampliar seu repertório lingüístico, apreender novos significados a partir de seus próprios enunciados e, por meio da deliberação consigo mesmo, convencer-se e persuadir-se. / This study aims at presenting the origins of the Neuro-Linguistic Programming (NLP), its main ideas, theoretical presuppositions and goals. Furthermore, it will be analyzed the meta-model, its relationship with language and its exploitation through the modeling process, all based on the book The structure of magic I: a book about language and therapy, by Richard Bandler and John Grinder, the founders of NLP. Moreover, it will be examined the transformations obtained from the derivation process, based on Noam Chomsky´s Transformational-generative grammar, with the goal of verifying its relationship with the meta-model. When exploiting the subject´s discourse submitted for the process of modeling, it will be verified in which way the new semantic contents revealed by the transformations could influence that subject and made him alter his vision of the world. For this analysis, it will be investigated also the classic theories of Argumentation, especially the conviction and persuasion concepts. It will also be verified that the process of modeling can offer resources to the subject, for him to enhance his linguistic vocabulary, to learn new meanings from his own sentences and to be able to persuade and convince himself through deliberating with his inner self.

Cette thèse se situe à l’intersection des domaines de la recherche en linguistique et du traitement automatique de la langue. Ces deux domaines se croisent pour la construction d’outils de traitement de texte, et des applications industrielles intégrant des solutions de désambiguïsation et d’interprétation de la langue.Une tâche difficile et très peu abordée et appliqué est arrivée sur les travaux de l’entreprise Techlimed, celle de l’analyse automatique des textes écrits en arabe. De nouvelles ressources sont apparues comme les lexiques de langues et les réseaux sémantiques permettant à la création de grammaires formelles d’accomplir cette tâche.Une métadonnée importante pour l’analyse de texte est de savoir « qu’est-ce qui est dit, et que signifie-t-il ? ». Le domaine de linguistique computationnelle propose des méthodes très diverses et souvent partielle pour permettre à l’ordinateur de répondre à de telles questions.L’introduction et l’application des règles de grammaire descriptives de langues dans les langages formels spécifiques au traitement de langues par ordinateur est l’objet principal de cette thèse.Au-delà de la réalisation d’un système de traitement et d’interprétation de textes en langue arabe, basé aussi sur la modélisation informatique, notre intérêt s’est porté sur l’évaluation des phénomènes linguistiques relevés par la littérature et les méthodes de leur formalisation en informatique.Dans tous les cas, nos travaux de recherche ont été testés et validés dans un cadre expérimental rigoureux autour de plusieurs formalismes et outils informatiques.Nos expérimentations concernant l'apport de la grammaire syntaxico-sémantique, a priori, ont montré une réduction importante de l’ambiguïté linguistique dans le cas de l'utilisation d’une grammaire à état fini écrite en Java et une grammaire générativetransformationnelle écrite en Prolog, intégrant des composants morphologiques, syntaxiques et sémantiques.La mise en place de notre étude a requis la construction d’outils de traitement de texte et d’outils de recherche d’information. Ces outils ont été construits par nos soins et sont disponible en Open-source.La réussite de l’application de nos travaux à grande échelle s’est conclue par la condition d’avoir de ressources sémantiques riches et exhaustives. Nous travaux ont été redirigés vers une démarche de production de telles ressources, en termes de recherche d’informations et d’extraction de connaissances. Les tests menés pour cette nouvelle perspective ont étéfavorables à d’avantage de recherche et d’expérimentation. / This thesis lies at the frontier of the fields of linguistic research and the automatic processing of language. These two fields intersect for the construction of natural language processing tools, and industrial applications integrating solutions for disambiguation and interpretation of texts.A challenging task, briefly approached and applied, has come to the work of the Techlimed company, that of the automatic analysis of texts written in Arabic. Novel resources have emerged as language lexicons and semantic networks allowing the creation of formal grammars to accomplish this task.An important meta-data for text analysis is "what is being said, and what does it mean". The field of computational linguistics offers very diverse and, mostly, partial methods to allow the computer to answer such questions.The main purpose of this thesis is to introduce and apply the rules of descriptive language grammar in formal languages specific to computer language processing.Beyond the realization of a system of processing and interpretation of texts in Arabic language based on computer modeling, our interest has been devoted to the evaluation of the linguistic phenomena described by the literature and the methods of their formalization in computer science.In all cases, our research was tested and validated in a rigorous experimental framework around several formalisms and computer tools.The experiments concerning the contribution of syntaxico-semantic grammar, a priori, have demonstrated a significant reduction of linguistic ambiguity in the case of the use of a finite-state grammar written in Java and a transformational generative grammarwritten in Prolog, integrating morphological, syntactic and semantic components.The implementation of our study required the construction of tools for word processing, information retrieval tools. These tools were built by us and are available in Open-source.The success of the application of our work in large scale was concluded by the requirement of having rich and comprehensive semantic resources. Our work has been redirected towards a process of production of such resources, in terms of informationretrieval and knowledge extraction. The tests for this new perspective were favorable to further research and experimentation.
