Ce mémoire présente une évaluation des différentes méthodes utilisées en lexicographie afin d’identifier les liens lexicaux dans les dictionnaires où sont répertoriées des collocations. Nous avons ici comparé le contenu de fiches du DiCo, un dictionnaire de dérivés sémantiques et de collocations créé selon les principes de la lexicologie explicative et combinatoire, avec les listes de cooccurrents générées automatiquement à partir du corpus Le Monde 2002. Notre objectif est ici de proposer des améliorations méthodologiques à la création de fiches de dictionnaire du type du DiCo, c’est-à-dire, des dictionnaires d’approche qualitative, où la collocation est définie comme une association récurrente et arbitraire entre deux items lexicaux et où les principaux outils méthodologiques utilisés sont la compétence linguistique de ses lexicographes et la consultation manuelle de corpus de textes. La consultation de listes de cooccurrents est une pratique associée habituellement à une approche lexicographique quantitative, qui définit la collocation comme une association entre deux items lexicaux qui est plus fréquente, dans un corpus, que ce qui pourrait être attendu si ces deux items lexicaux y étaient distribués de façon aléatoire. Nous voulons mesurer ici dans quelle mesure les outils utilisés traditionnellement dans une approche quantitative peuvent être utiles à la création de fiches lexicographiques d’approche qualitative, et de quelle façon leur utilisation peut être intégrée à la méthodologie actuelle de création de ces fiches. / This paper presents an evaluation of the various methods used in lexicography in order to identify the lexical bonds in dictionaries where collocations are indexed. We compared the contents of entries of the DiCo, a dictionary of semantic derivatives and collocations created according to the principles of explanatory and combinative lexicology, with the lists of cooccurrents generated automatically from the Le Monde 2002 corpus. Our objective here is to propose improvement in the methodology of creation of dictionary entry of DiCo-like dictionaries, i.e., dictionaries of a qualitative approach, where collocation is defined as the recurring and arbitrary associations between two lexical items and where the principal methodological tools used are the linguistic ability of its lexicographers and the manual consultation of corpus of text. The consultation of lists of cooccurrents is a practice associated traditionally with a quantitative lexicographical approach, which defines collocation as an association between two lexical items, which is more frequent, in a corpus, than what could be expected if these two lexical items were randomly distributed in corpus. We want to evaluate in what respect the tools used traditionally in a quantitative approach can be used for the creation of lexicographical entries of a qualitative approach, and how their use can be integrated into the current methology of creation of these entries.

Cette recherche porte sur la lexicologie, la lexicographie et l’enseignement/apprentissage du lexique. Elle s’inscrit dans le cadre du projet Modélisation ontologique des savoirs lexicographiques en vue de leur application en linguistique appliquée, surnommé Lexitation, qui est, à notre connaissance, la première tentative d’extraction des savoirs lexicographiques — i.e. connaissances déclaratives et procédurales utilisées par des lexicographes — utilisant une méthode expérimentale. Le projet repose sur le constat que les savoirs lexicographiques ont un rôle crucial à jouer en lexicologie, mais aussi en enseignement/apprentissage du lexique. Dans ce mémoire, nous décrirons les méthodes et les résultats de nos premières expérimentations, effectuées à l’aide du Think Aloud Protocol (Ericsson et Simon, 1993). Nous expliquerons l’organisation générale des expérimentations et comment les savoirs lexicographiques extraits sont modélisés pour former une ontologie. Finalement, nous discuterons des applications possibles de nos travaux en enseignement du lexique, plus particulièrement pour la formation des maîtres. / This research is about lexicology, lexicography and vocabulary teaching/learning. It is part of a project called Ontologization of lexicographic abilites for use in the fields of applied linguistics, nicknamed Lexitation, which is, to our knowledge, the first attempt at extracting lexicographic abilities using experimental techniques. The project relies on the assumption that lexicographic abilities play a role in teaching and acquisition of lexical knowledge, and not only in lexicography per se. We will describe the methods and results of our initial set of experiments, that are based on the use of so-called Think Aloud Protocol (Ericsson et Simon, 1993). We will explain how experiments have been set up and how we are currently proceeding with the extraction and modeling of various types of knowledge and strategies used by lexicographers while performing lexicographic tasks. Finally, we will present possible applications of our work in the field of language teaching, more specifically, teachers’ training.

Cette étude porte sur les différentes formalisations du sens linguistique dans le cadre de la théorie Sens-Texte (TST) ; elle s’intéresse notamment à la représentation sémantique, la représentation la plus importante dans la modélisation du sens d’énoncés et d’unités lexicales de la langue. Cette étude a trois objectifs : premièrement, décrire trois formalisations de la représentation sémantique existant dans la TST – les réseaux sémantiques, les définitions lexicographiques et les définitions de la BDéf (des définitions très formalisées) ; deuxièmement, identifier les disparités et les décalages entre les formalisations choisies ; troisièmement, proposer des modifications aux formalisations existantes pour réduire au maximum ces disparités. / This study explores the different formalisations of linguistic meaning as encountered in the Meaning-Text Theory (MST) framework. Its main interest is semantic representation, which is the most important representation in the modeling of the meaning of utterances and lexical units. This study has three objectives: first, describing three existing formalisations of semantic representation in the MST – semantic networks, lexicographical definitions, and BDéf definitions (definitions that are extremely formalized); second, identifying the discrepancies between these formalisations; finally, proposing modifications to these formalisations in order to reduce the disparities as much as possible.

Este estudo apresenta um levantamento de estruturas sintáticas causais e explicativas e sua correlação, respectivamente, com os modos narrativo e argumentativo de organização do texto, evidenciando a frequência de tais construções nos respectivos gêneros textuais: notícia, crônica, editorial e redação de vestibular. Para a coleta de dados, analisam-se 400 (quatrocentos) textos, 100 (cem) de cada gênero supramencionado. Há o confronto de conectivos que, na tradicional escolar, representam formas de expressão da causalidade (sentido restrito) e da explicação, repensando-se aspectos da descrição e do ensino de Língua Portuguesa, com vistas à proficiência discursiva na modalidade escrita. Aponta como principais resultados: a) a existência de três grupos de conectivos explicativos: os exclusivamente causais, os exclusivamente explicativos e os que exercem dupla função; b) a correlação entre os três modos verbais e a explicação, e, no caso da causalidade, uma correlação apenas com os modos verbais Indicativo e Subjuntivo; c) uma correspondência entre causalidade (no sentido estrito) e narração, e entre explicação e argumentação; d) a relação entre Factualidade e as estruturas causais, e entre o ato de fala chamado Justificativa e as orações explicativas, expressando não apenas ordens, pedidos, convites, opiniões e perguntas. Conclui que o estudo dos conectivos causais e explicativos deve estimular a reconstrução do conhecimento e a observância dos elementos verbais (disponíveis na língua) que são responsáveis pela construção dos sentidos. Além disso, que o ensino de Língua Portuguesa deve estar centrado em uma abordagem produtiva, mais funcional, não essencialmente classificatória e conteudista, de forma que a gramática, com a contribuição de estudos do discurso, promova o desenvolvimento de habilidades e competências de produção de textos. Não se propõe com isso que a tradição escolar seja descartada. Ao contrário, é mais uma reflexão, no caso, intradisciplinar, com vistas à construção de uma prática didático-pedagógica em língua materna / This study presents an assessment of causal and explicative syntactic structures and their respective correspondence with the narrative and argumentative modes of text organization, evidencing the frequency of such constructions in the following textual genres: news, chronicle, editorial and students writing in college entrance exams (vestibular). For data gathering, we have analyzed 400 (four hundred) texts, 100 (one hundred) of each aforementioned genres. A comparison is made with connectives which, according to traditional educational practices, represent ways of expressing cause (restrict sense) and explanation, and thus we rethink aspects of Portuguese language description and teaching, with the purpose of improving proficiency in written discourse. The principal findings are: a) the existence of three groups of explicative connectives: those which are solely causal, those which are solely explicative and those that comprise both functions; b) the correlation among the three verb moods and explanation, and, in the case of causality, the correlation only with Indicative and Subjunctive verb moods; c) the relationship between causality (in the strict sense) and narration, and between explanation and argumentation; d) the relationship between factuality and causal structures, and between the act of speech called Justification and explicative sentences, expressing not only orders, requests, invitations, opinions and questions. We conclude that the study of casual and explicative connectives should stimulate the reconstruction of knowledge and the analysis of verbal elements (available in the language), which are responsible for the construction of meanings. In addition, the teaching of Portuguese language should focus on a productive approach, more functional, not essentially based on classifications and contents, so that grammar, with the contribution of discourse studies, may foster the improvement of skills and competences in text writing. We do not propose, with this study, that traditional school teaching should be disregarded. On the contrary, this is only another approach, in this case, intradisciplinary, with the purpose of constructing a didactic-pedagogical practice for Portuguese language as mother tongue

This dissertation presents a qualitative study, whose main research question, analyze how it develops the explanatory universe of two people with total blindness on learning of geometry, from the relations with the knowledge that these individuals established to build knowledge geometric during their school lives. The research is inserted in the line of research: Science, scientific knowledge and techniques in contemporary societies of the Master in Science and Mathematics Teaching, Federal University of Sergipe. Falls into the area of Special Education and Mathematics Education in inclusive perspective. The route chosen in this work was determined by the voices of the two participants, so that through the speech, feelings and actions could explain how to build explanatory universe, which senses and relations with the knowledge established with the mathematical knowledge of geometry. The theoretical references pervade the ways of Inclusive Education (MANTOAN (2006), MANSINI (1994), SASSAKI (1999), SOUZA E SILVA (2005), SOUZA et al. (2005), STAINBACK & STAINBACK (1999), among others; and the relationship of theory and knowledge (CHARLOT 1999, 2000 , 2001 , 2005 and 2009), among others. As data collection instrument was used text production based on technical "balance of knowledge" - developed by the team ESCOL (Paris VIII), organized by Charlot (1999) - and three interview stages, one of which is based on interview technique developed by Pierre explicitness Vermersh (1994). This study was a qualitative approach involving the analysis of the content of the interviews to establish possible situations of similarities or differences between subject’s research participants. The results showed us that the person with total blindness, that does not have the involvement of other organs than sight, has the capacity to build an explanatory universe, with constructions of thought and objects of any geometric mathematical object, provided it has been prepared considering its features. The Relations with the knowledge of these people were based on the need for self-affirmation, considering them able to become independent subjects and citizens of the world. / Esta dissertação apresenta um estudo de natureza qualitativa, que teve como questão norteadora principal, analisar como se desenvolve o universo explicativo de duas pessoas com cegueira total sobre a aprendizagem da geometria, a partir das relações com o saber que esses sujeitos estabeleceram ao construir o conhecimento geométrico durante suas vidas escolar. A pesquisa está inserida na linha de pesquisa: Ciências, saberes científicos e técnicas nas sociedades contemporâneas do Mestrado em Ensino de Ciências e Matemática da Universidade Federal de Sergipe. Se enquadra na área da Educação Especial e Educação Matemática na perspectiva inclusiva. O percurso escolhido neste trabalho foi determinado pelas vozes das duas pessoas participantes da pesquisa, para que, através das falas, sentimentos e ações pudessem explicitar como se constrói o universo explicativo, quais os sentidos e as relações com o saber estabelecidas com o conhecimento matemático de geometria. Os referenciais teóricos perpassam os caminhos da Educação Inclusiva (MANTOAN (2006), MANSINI (1994), SASSAKI (1999), SOUZA E SILVA (2005), SOUZA et al. (2005), STAINBACK & STAINBACK (1999), dentre outros; e da teoria da Relação com o saber (CHARLOT 1999, 2000, 2001, 2005 e 2009), dentre outros. Como instrumento de coleta de dados foram utilizados produção de texto baseado na técnica “balanço do saber” – desenvolvida pela equipe ESCOL (Paris VIII), organizada por Charlot (1999) – e três etapas de entrevista, sendo uma delas baseada na entrevista de explicitação técnica desenvolvida por Pierre Vermersh (1994). Este trabalho teve uma abordagem qualitativa envolvendo a análise dos conteúdos das entrevistas para estabelecer possíveis situações de semelhanças ou diferenças entre os sujeitos participantes da pesquisa. Os resultados nos mostraram que a pessoa com cegueira total, que não possui o comprometimento de outros órgãos que não seja a visão, possui capacidade de construir um universo explicativo, com construções de objetos de pensamento e de qualquer objeto matemático geométrico, desde que tenha sido elaborado considerando suas particularidades. As Relações com o saber dessas pessoas basearam-se na necessidade de auto afirmação, considerando-as capazes de tornarem-se sujeitos independentes e cidadãos do mundo.

Cette recherche porte sur l’interface entre la sémantique lexicale et la syntaxe, et elle s’inscrit dans le cadre du projet de base lexicale DiCo (acronyme pour Dictionnaire de combinatoire) à l’Observatoire de Linguistique Sens-Texte [OLST] de l’Université de Montréal. Le projet découle d'une volonté d'inscrire de façon concise et complète, à même le dictionnaire, le comportement syntaxique typique à chaque unité lexicale. Dans cette optique, nous encodons la cooccurrence des lexies nominales du DiCo avec leurs actants à l'intérieur d'un tableau de régime lexical (aussi connu sous le nom de schéma valenciel, structure argumentale, cadre de sous-catégorisation, structure prédicats-arguments, etc.), en notant entre autres les dépendances syntaxiques de surface impliquées. Dans ce mémoire, nous présentons les propriétés syntaxiques d'une dépendance nominale du français, celle que nous avons nommée attributive adnominale, de façon à exposer une méthodologie d'identification et de caractérisation des dépendances syntaxiques de surface. Nous donnons également la liste des dépendances nominales régies identifiées au cours de ce travail. Par la suite, nous exposons la création d'une base de données de régimes généralisés du français nommée CARNAVAL. Finalement, nous discutons des applications possibles de notre travail, particulièrement en ce qui a trait à la création d'une typologie des régimes lexicaux du français. / This research focuses on the interface between lexical semantics and syntax, and is part of the lexical database project called DiCo (acronym for Dictionnaire de combinatoire) at the Observatoire de Linguistique Sens-Texte [OLST] at the University of Montreal. The project aims to register in a concise and complete way the typical syntactic behavior of each lexical unit directly in the dictionary. To this end, we encode the co-occurrence of the DiCo's nominal lexical units with their actants within a government pattern (also known as valency structure, subcategorization frame, predicate-argument structure, etc.), using, among other things, the surface syntactic dependencies involved. In this dissertation, we present the syntactic properties of a French nominal dependency, the one that we named attributive adnominale, so as to expose a methodology for the identification and the characterization of surface syntactic dependencies. We also give the list of valence-controlled nominal dependencies that were identified in our work. Subsequently, we describe the creation of a database of generalized French government patterns named CARNAVAL. Finally, we discuss possible applications of our work, particularly in regard to the creation of a typology of French government patterns.

En tant que syntagmes sémantiquement non-compositionnels, les locutions sont des unités lexicales à part entière, qui doivent avoir leur propre entrée dans un modèle du lexique. Elles doivent donc recevoir une définition lexicographique, ainsi qu’une description de leurscaractéristiques grammaticales. De plus, en vertu de leur signifiant syntagmatique, les locutionstémoignent – à des degrés divers – d’une flexibilité formelle (passivation, insertion de modificateurs, substitution de certains constituants, etc.).Notre thèse défend l’idée selon laquelle une description des locutions combinant à la fois l’identification des unités lexicales qui les composent et l’identification des relations de dépendance syntaxique qui unissent les unités constituantes, permettra de prédire leurs différents emplois possibles dans la phrase. Une telle description n’est possible que dans un modèle du lexique décrivant précisément la combinatoire des lexies. Notre recherche, basée sur les principes de la Lexicologie Explicative et Combinatoire, exploite et enrichit les données du Réseau Lexical du Français (RL-fr), ressource en cours de développement à l’ATILF.La thèse a deux principaux apports. Le premier est le développement d’un modèle de description lexico-syntaxique relativement fine des locutions du français. Le second est l’identification et l’étude de différentes variations structurales, syntaxiques et lexicales liées à la flexibilité formelle des locutions. Les variations des locutions sont mises en corrélation avec leurs structures lexico-syntaxiques, mais également avec leurs définitions lexicographiques. Ceci nous conduit à introduire la notion de projection structurale, centrale dans le continuum de la flexibilité formelle des locutions / As semantically non-compositional phrases, idioms are lexical units. Consequently, they must have their own entries in a lexical resource, with a lexicographic definition and grammatical characteristics. Furthermore, because of their phrasal signifier, idioms show – to varying degrees – a formal flexibility (passivization, attachment of modifiers, substitution of components,etc.)Our thesis defends the view that a description of idioms that combine identification of their lexical components and identification of dependency links between these components will permit to predict their formal variations. Such a description is possible only in a model of lexicon that describes precisely combinatorial proprieties of lexical units. Our thesis, based on the Explanatory Combinatorial Lexicology’s framework, exploits and enhances the data of the French Lexical Network (fr-LN). This resource is being developed at the laboratory ATILF (Nancy, France).The thesis makes two principal contributions to the study of phraseology. The first contribution is the development of a precise description of idioms’ lexico-syntactic structures. The second contribution is the indentification and the study of structural, syntactic and lexical variations linked to idioms’ formal flexibility. Idioms’ formal variations are correlated with their lexico-syntactic structures, but also with their lexicographic definitions. This work leads us to introduce the notion of structural projection, that plays a central role in the continuum of idiom’s formal flexibility

Des avantages et désavantages cognitifs existeraient chez l’enfant bilingue par rapport à son homologue unilingue, dû à l’activation constante des deux langues chez le bilingue et à son traitement langagier plus complexe. Cette surcharge de traitement affecterait d’ailleurs l’accès lexical des bilingues, qui auraient davantage de « mots sur le bout de la langue ». Puisque le discours pourrait être une mesure d’évaluation moins biaisée que les tests de vocabulaire normés et qui permettrait de saisir les compétences fondamentales lexicales des enfants, le Test of Word Finding in Discourse (TWFD ; German, 1991) a été utilisé afin d’évaluer l’incidence des manifestations des difficultés d’accès lexical (DAL ; répétition, révision, mot vide, commentaire métalinguistique ou métacognitif, substitution, pause ou interjection) dans trois situations discursives (2 narratives, 1 explicative) de 30 enfants québécois entre 7;1 et 10;8 ans (15 unilingues francophones et 15 bilingues simultanés français–anglais, dominants en français. L’alternance codique (code-switching), pertinente par la présence de la population bilingue, a aussi été étudiée. Aucune différence n’a été obtenue entre les enfants unilingues et bilingues pour l’incidence des manifestations des DAL. Davantage de mots vides et de révisions ont par ailleurs été obtenus dans le discours explicatif alors que le taux de pauses était plus élevé dans le discours narratif et ce, pour tous les enfants. L’évaluation de la productivité de langage a montré une différence entre les enfants bilingues et unilingues, où ces derniers ont obtenus des moyennes supérieures pour le nombre d’énoncés total, le nombre de mots total et le nombre de mots différents. Aussi, la longueur moyenne de l’énoncé était en moyenne plus longue, pour tous les enfants, dans le discours explicatif que dans la narration. Enfin, les manifestations du MBL en discours seraient une mesure sensible d’évaluation des enfants typiques bilingues, puisque leurs résultats de production ne diffèrent pas de ceux des unilingues typiques, ce qui pourrait éviter de les surdiagnostiquer avec un trouble de langage. / Cognitive advantages and disadvantages seem to exist in the bilingual child compared to his unilingual counterpart, due to the constant activation of the two languages in the bilingual and to his subsequent more complex language processing. This processing overload seems to affect the lexical access of bilinguals, who would have more words on the “tip of their tongue". Since discourse could be a less biased assessment measure than standardized vocabulary tests and would capture children's basic lexical skills, the Test of Word Finding in Discourse (TWFD ; German, 1991) was used to assess the presence of word-finding difficulties (WFD ; repetition, revision, empty word, metalinguistic or metacognitive comment, substitution, pause or interjection) in three discourse situations (2 narrative, 1 expository) of 30 Quebec children between 7;1 and 10;8 years old (15 unilingual francophones and 15 French-English bilinguals (French dominant)). Code-switching, relevant to the presence of the bilingual population, was also studied. No difference was found between monolingual and bilingual children in the WFD measure for the incidence of WFD. More empty words and revisions were obtained in the expository speech for all children, while the rate of pauses was higher in the narrative speech. The assessment of language productivity showed a difference between bilingual and monolingual children, where the latter obtained higher averages for the total number of utterances, the total number of words and the number of different words. Also, the mean length of utterances was longer in the expository discourse than in the narrative, regardless of languages spoken by the children. Finally, WFD manifestations in discourse could be a sensitive measure of assessment for typical bilingual children, since their production scores did not differ from those of typical monolinguals. This could prevent overidentification of language disorders in this population.
