The present work provides a comprehensive overview of causativity - its definition, classification and characteristics - in a typological perspective. It outlines the development of causativity in English, from Indo-European to Present Day English with main emphasis on the Old English period and the factors that had led to the state of causative verbs at that time. In Research Part, it inquires into the possible competition between morphological and syntactic causatives and its future after- effects with respect to the described typology. Key words: causation, causativity, causative verb, causative opposition, morphological causative verb, syntactic causative expression, labile causative opposition, Old English

Notre thèse s'adresse aux francophones qui veulent apprendre l'arabe, son lexique, sa syntaxe et sa sémantique. L'une des difficultés majeures que rencontre l'apprenant dès qu'il entre en contact avec notre langue, est le traitement des aspects et des temps, localement et dans l'ensemble de l'énoncé. Dans le cadre, d'une description des aspects et des temps nous sommes contraints de faire une étude générale de la morphologie verbale et des catégories grammaticales de l'arabe standard. Mais nous devons aussi travailler sur les mêmes structures en français qui est la langue source de nos apprenants afin de mettre en regard les deux systèmes linguistiques. Le second visage de ce travail est nettement plus technologique. Nous avons insisté sur les interfaces des leçons que nous présentons sur Internet afin de montrer comment elles participent de façon active à la compréhension des contenus par les apprenants. / Our thesis is intended for francophones wishing to learn Arab, its lexicon, its syntax and its semantics. One of the main difficulties which the learner encounters as soon as he enters into contact with our language is the treatment of aspects and of tenses, bath locally and throughout the whole statement or text. The description of aspects and tenses requires us to make a general study of the verbal morphology of the grammatical structures of standard Arab. But we are also brought to work on the same structures in French which is the source language of the learners in order to make a comparative study of the two language-systems. The second face of this work is considerab1y more technical. We have insisted on the interfaces of the lessons that we present on Internet in order to show how they contribute in an active way to the understanding of the contents by the learners

This diploma thesis deals with explicitness and semantic explicitations in translation. Its goal is to confirm or disprove the explicitation hypothesis of S. Blum-Kulka, according to which translated texts are more explicit than their originals, regardless of the language of translation. The thesis is divided into two parts. The theoretical part focuses on the definition of explicitness and explicitation, presents explicitation from the point of view of terminology, translation universals, the cognitive process of translating and the contribution of corpus linguistics to the research of different forms of explicitation. The theoretical part also contains division of explicitation into different types and its classification among other translation procedures. The empirical part is based on a detailed analysis of excerpts obtained from French and Czech belletristic originals and their translations through which the semantic explicitations are researched. The analysis is concluded by a summary of all obtained results and by their confrontation with the explicitation hypothesis.

Dans cette thèse, nous présentons une analyse syntaxique du vietnamien de Hô-Chi-Minh-Ville, dans la lignée de la syntaxe fonctionnelle mise en place par André Martinet et développée par la suite par ses continuateurs. Dans un premier temps, nous nous sommes intéressée au degré d’opposition verbo-nominal en vietnamien : nous proposons tout d’abord une synthèse des travaux menés à ce sujet, avant d’exposer notre analyse en classes, en nous appuyant sur des critères strictement syntaxiques. Une étude syntaxique détaillée des modalités (déterminants non déterminables) – les modalités nominalisantes, les modalités de degré, les modalités prédicatives et les modalités injonctives – a été nécessaire. Ces unités permettent de distinguer des comportements différents, et l’identification des grandes classes lexicales du vietnamien : nominaux, adjectifs, modaux et verbaux. Il apparait que ces classes d’unités s’organisent en un continuum, avec à un pôle les nominaux, à l’autre les verbaux. Dans un second temps, l’analyse porte sur les différents types de structures prédicatives du vietnamien. La variété des constructions – nucléaires et connectives – est au centre de l’étude, ainsi que l’identification des différentes fonctions. Enfin, nous exposons une analyse des “séries verbales”, phénomène très courant en vietnamien, mais décrivant en fait des réalités très diverses. Tout au long de l’analyse, nous accordons une importance particulière à la variation et aux zones de changements (réanalyses, lexicalisations, grammaticalisations), faisant état de la dynamique des différentes structures et de la langue elle-même. / We present here a syntaxic analysis of the Vietnamese language spoken in Ho Chi Minh City, in line with the functional syntax introduced by André Martinet and developed later by his followers. In a first part, we examined the extent of noun/verb opposition in Vietnamese. After a synthesis of work on this subject, we present our own analysis of the lexical classes, relying on strictly syntactic criteria. A detailed study of the syntactic modalités (undeterminable determinants) - nominalizing undeterminable determinants, undeterminable determinants of degree, predicative undeterminable determinants and injunctive undeterminable determinants - was necessary. These units are used to distinguish different behaviors, and leads to the identification of major lexical classes in Vietnamese: nominals, adjectives, modals and ‘verbals’. It appears that these classes of units are organized along a continuum. In a second part, the analysis focuses on the different types of predicative structures in Vietnamese. The variety of structures - nuclear and connective - is central to the study as well as the identification of the different functions. Finally, we present an analysis of "serial verb constructions" very common in Vietnamese, but actually reflecting very different realities. Throughout this study, we pay particular attention to the variation and change (reanalysis, lexicalizations, grammaticalizations), referring to the dynamics of the various structures and of the Vietnamese language itself.

De nombreux chercheurs se sont intéressés aux particularités lexicales et pragmatico-discursives du langage que les parents adressent à leur jeune enfant. La revue de la littérature sur ce point montre qu’il existe tantôt des différences tantôt des ressemblances entre les mères et les pères. Cependant, les caractéristiques syntaxiques du langage qu’adressent les parents à leur enfant font rarement l’objet d’études. Par ailleurs, les études portant sur les effets du dialogue, des genres de discours déployés durant celui-ci et des activités dans lesquelles interagissent les dyades parent-enfant sur le développement syntaxique de l’enfant sont encore peu développées.Cette thèse s’articule ainsi autour de trois objectifs : i) mieux cerner les différences et les similitudes qui existent dans le langage maternel et paternel aux niveaux syntaxique et pragmatico-discursif, et d’en observer l’influence sur le langage de l’enfant, ii) évaluer l’effet de l’activité en cours sur les productions et les conduites de dyades mère-enfant et père-enfant, iii) interroger les liens qui existent entre dimension syntaxique et dimension pragmatico-discursive dans le processus d’acquisition du langage.Sept enfants francophones natifs, âgés de 3 à 4 ans, et leurs parents ont été observés dans deux activités : un jeu symbolique et un jeu de cartes illustrées. Leurs productions ont été analysées au niveau syntaxique, tout en considérant certaines propriétés discursives et pragmatiques liées aux usages de ces productions (statut de l’interlocuteur de l’enfant, types d’activité et aspects pragmatico-discursifs). Nos résultats suggèrent que le statut de l’interlocuteur de l’enfant, associé aux types d’activités et aux spécificités du dialogue, constituent un faisceau de variables qu’il convient de considérer si l’on veut mieux décrire les usages syntaxiques des enfants et la variabilité de ceux-ci. / Many researchers have studied lexical and pragmatic-discursive particularities of the language that parents use to address their young child. A literature review shows that there are both differences and similarities between mothers and fathers. However, characteristics of the language that parents use for addressing their child have rarely been studied. Moreover, there is a paucity of studies examining the effects on the child’s syntactic development of dialogue, speech genres and activities during which parent-child dyads interact.This thesis has three goals: i) improve understanding of differences and similarities in the syntactic and pragmatic-discursive aspects of maternal and paternal language and their effect on the child’s language, ii) evaluate the effect of the ongoing activity on the production and the use of mother-child and father-child dyads, iii) investigate the relation between syntactic and pragmatic-discursive dimensions during the language learning process.Seven 3-4 years old native French-speaking children and their parents were observed during two activities: a symbolic play and a picture card game. The syntactic dimensions of their productions were analyzed while considering certain discursive and pragmatic properties related to the use of these productions (status of the child’s interlocutor, type of activity and pragmatic-discursive aspects). Our results suggest that the status of the child’s interlocutor, associated with the type of activity and the dialogue’s specificities, form a body of variables that should be taken into account in order to better describe children’s syntactic uses and their variability.

Na última década métodos sintáticos vêm sendo bastante empregados para reconhecimento de padrões em imagens. Uma revisão sistemática sobre o assunto indicou que há trabalhos sobre a utilização de gramáticas para reconhecimento de objetos específicos em imagens, reconhecimento de texturas, construção de objetos, segmentação de imagens, mudança de escala de imagens e reconhecimento de layouts de páginas e documentos. Foi percebido que apenas alguns dos trabalhos analisados apresentavam métodos de inferência gramatical. Percebida essa lacuna, este trabalho teve como objetivo avaliar a utilização de gramáticas estocásticas inferidas a partir de amostras de treinamento que continham as estruturas de quadtrees das imagens no problema de classificação de imagens. Para atingir tal objetivo foram utilizados e adaptados dois algoritmos de inferência gramatical e um algoritmo de estimação de probabilidades responsável por transformar as gramáticas livres de contexto inferidas em gramáticas livres de contexto estocásticas. Os resultados obtidos mostram que as técnicas propostas podem ser utilizadas na classificação de figuras geométricas. Entretanto, embora o desempenho com quadtrees não tenha sido excelente, ficou claro que o uso de gramáticas pode ser uma abordagem interessante para a classificação de imagens. / In the last decade syntactic methods have been widely used for pattern recognition in images. A systematic review on this subject indicated that there are works about the usage of grammars for recognizing specific objects in images, recognition of textures, construction of objects, image segmentation, image scaling, and recognition of layouts in documents. It was noticed that only some of the analyzed studies showed methods of grammatical inference. Perceived this gap, this study aimed to evaluate the usage of stochastic grammars inferred from training samples containing structures of quadtrees of images in image classification problem. To achieve this goal it was used and adapted two algorithms for grammatical inference and one algorithm of probability estimation responsible for transforming the inferred context-free grammars in stochastic context-free grammars. The results show that the proposed techniques can be used in the classification of geometric figures. However, although the performance with quadtrees has not been excellent, it was clear that the use of grammars can be an interesting approach for image classification.

Na atualidade, o interesse pelo uso de ontologias tem sido incrementado. No entanto, o processo de construção pode ser custoso em termos de tempo. Para uma ontologia ser construída, precisa-se de um especialista com conhecimentos de um editor de ontologias. Com a finalidade de reduzir tal processo de construção pelo especialista, analisamos e propomos um método para realizar aprendizado de ontologias (AO) de forma supervisionada. O presente trabalho consiste em uma abordagem combinada de diferentes técnicas no AO. Primeiro, usamos uma técnica estatística chamada C/NC-values, acompanhada da ferramenta Cogroo, para extrair os termos mais representativos do texto. Esses termos são considerados por sua vez como conceitos. Projetamos também uma gramática de restrições (GR), com base na informação linguística do Português, com o objetivo de reconhecer e estabelecer relações entre conceitos. Para poder enriquecer a informação na ontologia, usamos a análise de conceitos formais (ACF) com o objetivo de identificar possíveis superconceitos entre dois conceitos. Finalmente, extraímos ontologias para os textos de três temas, submetendo-as à avaliação dos especialistas na área. Um web site foi feito para tornar o processo de avaliação mais amigável para os avaliadores e usamos o questionário de marcos de características proposto pelo método OntoMetrics. Os resultados mostram que nosso método provê um ponto de partida aceitável para a construção de ontologias. / Nowadays, the interest in the use of ontologies has increased, nevertheless, the process of ontology construction can be very time consuming. To build an ontology, we need a domain expert with knowledge in an ontology editor. In order to reduce the time needed by the expert, we propose and analyse a supervised ontology learning (OL) method. The present work consists of a combined approach of different techniques in OL. First, we use a statistic technique called C/NC-values, with the help of the Cogroo tool, to extract the most significant terms. These terms are considered as concepts consequently. We also design a constraint grammar (CG) based in linguistic information of Portuguese to recognize relations between concepts. To enrich the ontology information, we use the formal concept analysis (FCA) in order to discover a parent for a set of concepts. In order to evaluate the method, we have extracted ontologies from text on three different domains and tested them with corresponding experts. A web site was built to make the evaluation process friendlier for the experts and we used an evaluation framework proposed in the OntoMetrics method. The results show that our method provides an acceptable starting point for the construction of ontologies.

Dans la première partie de ce manuscrit nous étudions les fonctions rationnelles, c'est-à-dire définies par des transducteurs unidirectionnels. Notre objectif est d'étendre aux transductions les nombreuses correspondances logique-algèbre qui ont été établies concernant les langages, notamment le célèbre théorème de Schützenberger-McNaughton-Papert. Dans le cadre des fonctions rationnelles sur les mots finis, nous obtenons une caractérisation à la Myhill-Nerode en termes de congruences d'indice fini. Cette caractérisation nous permet d'obtenir un résultat de transfert, à partir d'équivalences logique-algèbre pour les langages vers des équivalences pour les transductions. En particulier nous montrons comment décider si une fonction rationnelle est définissable en logique du premier ordre. Sur les mots infinis, nous pouvons également décider la définissabilité en logique du premier ordre, mais avec des résultats moins généraux.Dans la seconde partie nous introduisons une logique pour les transductions et nous résolvons le problème de synthèse régulière : étant donnée une formule de la logique, peut-on obtenir un transducteur bidirectionnel déterministe satisfaisant la formule ? Les fonctions réalisées par des transducteurs bidirectionnels déterministes sont caractérisés par plusieurs modèles différents, y compris par les transducteurs MSO, et ont ainsi été nommées transductions régulières. Plus précisément nous fournissons un algorithme qui produit toujours une fonction régulière satisfaisant une spécification donnée en entrée.Nous exposons également un lien intéressant entre les transductions et les mots avec données. Par conséquent nous obtenons une logique expressive pour les mots avec données, pour laquelle le problème de satisfiabilité est décidable. / In the first part of this manuscript we focus on the study of rational functions, functions defined by one-way transducers.Our goal is to extend to transductions the many logic-algebra correspondences that have been established for languages, such as the celebrated Schützenberger-McNaughton-Papert Theorem. In the case of rational functions over finite words, we obtain a Myhill-Nerode-like characterization in terms of congruences of finite index. This characterization allows us to obtain a transfer result from logic-algebra equivalences for languages to logic-algebra equivalences for transductions. In particular, we show that one can decide if a rational function can be defined in first-order logic.Over infinite words, we obtain weaker results but are still able to decide first-order definability.In the second part we introduce a logic for transductions and solve the regular synthesis problem: given a formula in the logic, can we obtain a two-way deterministic transducer satisfying the formula?More precisely, we give an algorithm that always produces a regular function satisfying a given specification.We also exhibit an interesting link between transductions and words with ordered data. Thus we obtain as a side result an expressive logic for data words with decidable satisfiability.

Le principal objectif de cette thèse est d'étudier l'incidence des erreurs prépositionnelles sur l'intelligibilité de productions en L2 anglais par des apprenants francophones. Après un résumé des caractéristiques sémantiques et morpho-syntaxiques des prépositions en anglais et en français, nous abordons les questions liées à l'acquisition d'une langue seconde en général et à l'acquisition des prépositions en particulier, afin d' identifier les facteurs qui peuvent rendre leur acquisition problématique en L2. Nous proposons également des solutions pédagogiques pour améliorer l'apprentissage des prépositions en anglais. Afin de mesurer l'intelligibilité, nous analysons un corpus de productions orales et écrites contenant des emplois erronés, répartis entre erreurs lexciales et erreurs lexico- grammaticales (additions, omissions ou substitutions). Les résultats de cette analyse permettent de voir dans quelle mesure les erreurs prépositionnelles affectent l'intelligibilité du message. / The main objective of our thesis paper is to examine the intelligibility of erroneous prepositional uses produced by French learners of English. We begin with an overview of the semantico-syntactic properties of English and French prepositions. Then we give an account of second language acquisition theories, and we highlight the acquisition of English prepositions by listing a number of reasons that are likely to make them problematic for L2 learners. We also propose certain effective pedagogical approaches to teaching English prepositions/particles. To measure intelligibility, we assess an oral and a written corpus containing L2 erroneous constructions. Our error tagset is divided into lexical and lexico-grammatical errors (addition, omission and substitution). The results of our corpus analysis allow us to observe the extent to which erroneous spatial prepositions may affect the intelligibility of the transferred message.
