L'objectif de cette thèse est d'étudier le développement du système lexico-sémantique chez les enfants monolingues et bilingues. La question posée est la suivante : quand et comment les significations des mots commencent à être reliées entre elles et à s'intégrer dans un système sémantique interconnecté. Dans un premier temps, trois études ont été menées chez des enfants monolingues français. L'Etude 1, a pour but d'observer si les mots sont organisés selon des liens taxonomiques (e.g., cochon - cheval). L'Etude 2 explore si l'effet d'amorçage sémantique est sous-tendu par des mécanismes cognitifs, comme les processus d'activation automatique et contrôlé. Puis enfin, l'Etude 3 observe si les mots sont organisés en fonction de leur distance de similarité sémantique (e.g., vache - mouton versus vache - cerf). Dans un deuxième temps, deux études ont été conduites chez des enfants apprenant deux langues simultanément. L'Etude 4 vise à déterminer si les mots sont taxonomiquement liés dans chacune des langues. L'Etude 5 explore si les mots présentés dans une langue activent leurs représentations sémantiques dans l'autre langue et vice versa. Dans le but de répondre à ces questions, le traitement lexico-sémantique a été étudié en utilisant deux techniques : l'eye-tracking et les potentiels évoqués (PEs). Ces deux techniques enregistrent lors de la présentation des mots des réponses comportementales (Etude 3) et neuronales (Etude 1, 2, 4 et 5) de haute résolution temporelle. Les Etudes 1 et 2 montrent que chez les monolingues les mots sont liés taxonomiquement à l'âge de 18 et 24 mois. Durant le développement du langage, les deux processus d'activation automatique et contrôlé sont impliqués dans le traitement des mots (Etude 2). L'Etude 3 montre qu'à 24 mois, les mots sont organisés dans le système lexico-sémantique en développement selon la distance des similarités sémantiques. L'Etude 4 montre que chez les enfants bilingues, le traitement sémantique ne diffère pas selon les deux langues, mais la topographie des PEs varie selon la langue traitée. L'Etude 5 montre que les mots présentés dans une langue activent leurs représentations sémantiques dans la deuxième langue et vice versa. Toutefois, la topographie des PEs est modulée selon la direction de traduction. Ces résultats suggèrent que l'acquisition de deux langues, bien qu'elle soit très précoce, requière deux ressources neuronales bien distinctes, sous-tendant ainsi le traitement lexico-sémantique des langues dominante et non-dominante. / The present doctoral research explored the developing lexical-semantic system in monolingual and bilingual toddlers. The question of how and when word meanings are first related to each other and become integrated into an interconnected semantic system was investigated. Three studies were conducted with monolingual French learning children which aimed at exploring how words are organized, that is, according to taxonomic relationships (e.g., pig - horse) and to semantic similarity distances between words (e.g., cow - sheep versus cow - deer), and whether cognitive mechanisms, such as automatic activation and controlled processes, underlie priming effects. An additional two studies conducted with children learning two languages simultaneously, aimed at determining, first, whether taxonomically related word meanings, in each of the two languages, are processed in a similar manner. The second goal was to explore whether words presented in one language activate words in another language, and vice versa. In an attempt to answer these questions, lexical-semantic processing was explored by two techniques: eye-tracking and event-related potentials (ERPs) techniques. Both techniques provide high temporal resolution measures of word processing but differ in terms of responses. Eye-movement measurements (Study III) reflect looking preferences in response to spoken words and their time-course, whereas ERPs reflect implicit brain responses and their activity patterns (Study I, II, IV, and V). Study I and II revealed that words are taxonomically organized at 18 and 24-month-olds. Both automatic and controlled processes were shown to be involved in word processing during language development (Study II). Study III revealed that at 24-month-olds, categorical and feature overlap between items underpin the developing lexical-semantic system. That is, lexical-items in each semantic category are organized according to graded similarity distances. Productive vocabulary skills influenced word recognition and were related to underlying cognitive mechanisms. Study IV revealed no differences in terms of semantic processing in the bilinguals¿ two languages, but the ERP distribution across the scalp varied according to the language being processed. Study V showed that words presented in one language activate their semantic representations in the second language and the other way around. The distribution of the ERPs depended, however, on the direction of translation. The results suggest that even early dual language experience yields distinct neural resources underlying lexical-semantic processing in the dominant and non-dominant languages during language acquisition.

A comunicação multilíngue é uma tarefa cada vez mais imperativa no cenário atual de grande disseminação de informações em diversas línguas. Nesse contexto, são de grande relevância os sistemas de tradução automática, que auxiliam tal comunicação, automatizando-a. Apesar de ser uma área de pesquisa bastante antiga, a Tradução Automática ainda apresenta muitos problemas. Um dos principais problemas é a ambigüidade lexical, ou seja, a necessidade de escolha de uma palavra, na língua alvo, para traduzir uma palavra da língua fonte quando há várias opções de tradução. Esse problema se mostra ainda mais complexo quando são identificadas apenas variações de sentido nas opções de tradução. Ele é denominado, nesse caso, \"ambigüidade lexical de sentido\". Várias abordagens têm sido propostas para a desambiguação lexical de sentido, mas elas são, em geral, monolíngues (para o inglês) e independentes de aplicação. Além disso, apresentam limitações no que diz respeito às fontes de conhecimento que podem ser exploradas. Em se tratando da língua portuguesa, em especial, não há pesquisas significativas voltadas para a resolução desse problema. O objetivo deste trabalho é a proposta e desenvolvimento de uma nova abordagem de desambiguação lexical de sentido, voltada especificamente para a tradução automática, que segue uma metodologia híbrida (baseada em conhecimento e em córpus) e utiliza um formalismo relacional para a representação de vários tipos de conhecimentos e de exemplos de desambiguação, por meio da técnica de Programação Lógica Indutiva. Experimentos diversos mostraram que a abordagem proposta supera abordagens alternativas para a desambiguação multilíngue e apresenta desempenho superior ou comparável ao do estado da arte em desambiguação monolíngue. Adicionalmente, tal abordagem se mostrou efetiva como mecanismo auxiliar para a escolha lexical na tradução automática estatística / Crosslingual communication has become a very imperative task in the current scenario with the increasing amount of information dissemination in several languages. In this context, machine translation systems, which can facilitate such communication by providing automatic translations, are of great importance. Although research in Machine Translation dates back to the 1950\'s, the area still has many problems. One of the main problems is that of lexical ambiguity, that is, the need for lexical choice when translating a source language word that has several translation options in the target language. This problem is even more complex when only sense variations are found in the translation options, a problem named \"sense ambiguity\". Several approaches have been proposed for word sense disambiguation, but they are in general monolingual (for English) and application-independent. Moreover, they have limitations regarding the types of knowledge sources that can be exploited. Particularly, there is no significant research aiming to word sense disambiguation involving Portuguese. The goal of this PhD work is the proposal and development of a novel approach for word sense disambiguation which is specifically designed for machine translation, follows a hybrid methodology (knowledge and corpus-based), and employs a relational formalism to represent various kinds of knowledge sources and disambiguation examples, by using Inductive Logic Programming. Several experiments have shown that the proposed approach overcomes alternative approaches in multilingual disambiguation and achieves higher or comparable results to the state of the art in monolingual disambiguation. Additionally, the approach has shown to effectively assist lexical choice in a statistical machine translation system

In this work, we test two novel methods of using word embeddings to detect lexical semantic change, attempting to overcome limitations associated with conventional approaches to this problem. Using a diachronic corpus spanning over a hundred years, we generate word embeddings for each decade with the intention of evaluating how meaning changes are represented in embeddings for the same word across time. Our approach differs from previous works in this field in that we encode words as probabilistic Gaussian distributions and bimodal probabilistic Gaussian mixtures, rather than conventional word vectors. We provide a discussion and analysis of our results, comparing the approaches we implemented with those used in previous works. We also conducted further analysis on whether additional information regarding the nature of semantic change could be discerned from particular qualities of the embeddings we generated for our experiments. In our results, we find that encoding words as probabilistic Gaussian embeddings can provide an enhanced degree of reliability with regard to detecting lexical semantic change. Furthermore, we are able to represent additional information regarding the nature of such changes through the variance of these embeddings. Encoding words as bimodal Gaussian mixtures however is generally unsuccessful for this task, proving to be not reliable enough at distinguishing between discrete senses to effectively detect and measure such changes. We provide potential explanations for the results we observe, and propose improvements that can be made to our approach to potentially improve performance.

Esta tese, com o intuito de contribuir para uma reflexão em torno da história da formação da língua portuguesa no Brasil, propõe como objetivo geral realizar um estudo do léxico no município de Cáceres-MT, tendo como base a discussão sobre manutenção, tendência à manutenção, desuso, tendência ao desuso e neologismo semântico de unidades lexicais extraídas de um manuscrito oitocentista. Os objetivos específicos são os seguintes: (i) compreender a história social da Capitania de Mato Grosso e do município de Cáceres, a partir das informações constantes no manuscrito Memoria, e aspectos que envolvam as condições de produção do documento e a biografia do autor; (ii) levantar o léxico do manuscrito, com recorte nos substantivos e adjetivos para servir de base na seleção das unidades lexicais a serem testadas in loco, e investigar a acepção registrada no documento das unidades lexicais, caracterizando, assim, o léxico do período oitocentista; (iii), fazer um cotejo lexicográfico abrangendo dicionários gerais dos séculos XVIII ao XXI; (iv) testar e identificar, a partir do corpus oral constituído por meio de pesquisa de campo na região urbana cacerense, o grau de manutenção, tendência à manutenção, desuso, tendência ao desuso e neologismo semântico em relação às unidades lexicais e suas respectivas acepções registradas no manuscrito. Dessa forma, toma-se como corpus de língua escrita de análise o manuscrito oitocentista Memoria sobre o plano de guerra offensiva e deffensiva da Capitania de Matto Grosso e, a partir das unidades lexicais selecionadas e extraídas dele, realizou-se a pesquisa de campo para o recolhimento do corpus de língua oral. Antes dessa recolha, tendo como base teórico-metodológica as disciplinas de Dialetologia e de Geolinguística, selecionou-se a localidade (município de Cáceres - MT) e os informantes (total de dezesseis); elaborou-se o questionário semântico-lexical, considerando fundamentalmente a proposta apresentada pelo Comitê Nacional do Projeto ALiB (2001); e realizou-se a pesquisa de campo e as transcrições das entrevistas. Para análise de natureza semântico-lexical dos corpora, recorreu aos estudos lexicográficos e lexicológicos. Tomando por base os resultados do estudo realizado, constatou-se que na realidade linguística do informante cacerense encontram-se unidades que já integravam o léxico oitocentista da língua portuguesa escrita no Brasil, ou seja, há uma memória semântico-lexical que se mantém no sistema lexical, provavelmente, devido às condições sócioculturais do município de Cáceres, Mato Grosso, cuja população, em grande parte, por quase duzentos anos, viveu na área rural. Todavia, vislumbrou-se um certo equilíbrio entre a manutenção do léxico oitocentista sem deixar de lado a inovação e o mecanismo polissêmico constitutivo do léxico. / This thesis aims to contribute for a reflection on the history of Brazilian Portuguese language formation by proposing a study on the lexicon in the municipality of Cáceres, State of Mato Grosso, based on a discussion on the maintenance, the tendency to maintain, the disuse, the tendency to disuse and the semantic neologism of lexical units extracted from an eighthundredth manuscript. The specific goals of the study are the following: (i) understand the social history of the Mato Grosso Captainship and the municipality of Cáceres from the information available in the manuscript Memoria, and from aspects involving the conditions of production of the document and the authors biography; (ii) survey the lexicon of the manuscript, taking nouns and adjectives as the basis in the selection of lexical units to be tested in loco and investigate the meaning of lexical units registered in the document, thus characterizing the lexicon of the eight-hundredth period; (iii) carry out a lexicographical comparison including general dictionaries from the 18th to 21th centuries; (iv) test and identify, from the oral corpus built through the field work in the urban region of Cáceres, the degree of maintenance, the tendency to maintain, the disuse, the tendency to disuse and the semantic neologism regarding the lexical units and their respective meanings recorded in the manuscript. FFIn In order to achieve these goals, we take the eight-hundredth manuscript Memoria sobre o plano de Guerra offensive e deffensiva da Capitania de Matto Grosso [Memoir on the Offensive and Defensive War Plan of Matto Grosso Captainship] as a written language corpus for analysis and from the lexical units extracted and selected from this work we carried out field work to collect an oral language corpus. Before collecting this material, the courses Dialectology and Geolinguistics were used as theoretical and methodological basis for the selection of the site (municipality of Cáceres, State of Mato Grosso) and the informants (a total of sixteen). We then prepared a semantic-lexical questionnaire essentially considering the proposal presented by the National Project Committee (ALiB, 2001) and carried out the field research and the transcription of the interviews. Lexicographical and lexicological studies were used in the analysis of the lexical-semantic nature of the corpora. Building on the results of the study, we found out that the linguistic reality of the Cáceres informant showed units already comprised in the eight-hundredth lexicon of written Portuguese language in Brazil, that is, there is a semantic-lexical memory remaining in the lexical system, probably due to the sociocultural conditions of the municipality of Cáceres, State of Mato Grosso, where, for almost two hundred years, most of the population lived in the rural area. Nonetheless, a certain balance between the maintenance of the eight-hundredth lexicon was conceived without leaving aside innovation and the polysemic mechanism constituting the lexicon.

Esta tese teve como objetivo identificar a norma semântico-lexical de cinco municípios da Região Norte do Alto Tietê- ReNAT, no estado de São Paulo,e pauta-se pelos estudos dialetológicos, geolinguísticos e sociogeolinguísticos. O local da pesquisa, a antiga Vila de Nossa Senhora da Conceição dos Guarulhos, é atualmente uma região composta por cinco municípios: Guarulhos, Arujá, Santa Isabel, Mairiporã e Nazaré Paulista. Está situada na Região Metropolitana de São Paulo, com exceção do quinto município, Nazaré Paulista, localizado na microrregião de Atibaia. A origem da região composta pelos cinco municípios, corpus do trabalho, remonta à época da fundação de São Paulo. Três municípios estão situados na região do Alto Tietê, ao norte do rio que leva o mesmo nome, por isso é denominada ReNAT. A vila era inicialmente povoada pelos índios Maromomis. A tese fundamentou-se nos trabalhos linguísticos voltados para a Dialetologia, a Geolinguística a Sociolinguística variacionista, a Sociolinguística interacional, a Semântica e a Lexicologia. Além do tratamento quantitativo dos dados, conforme a proposta de Muller, privilegiou a abordagem dos aspectos semânticos-lexicais a partir de Pottier e Rastier, e baseou-se na concepção de norma de Coseriu. Assim, de acordo com os procedimentos teórico-metodológicos atuais da Geolinguística e da Sociogeolinguística, aplicaram-se as 202 questões do questionário Semântico-Lexical (QSL) do projeto ALiB e, também, 31 questões do Questionário Semântico-Lexical do Projeto Estudo sociogeolinguístico do Município de São Paulo, elaborado pelo Grupo de Pesquisa em Dialetologia e Geolinguística (GPDG) da Universidade de São Paulo. As entrevistas foram desenvolvidas in loco, ou seja, nos seis pontos da pesquisa, localizados nos cinco municípios. As 233 questões, dos dois questionários, foram aplicadas a 24 sujeitos-entrevistados de ambos os gêneros masculino e feminino em duas faixas etárias, quais sejam: 18 a 30 anos e 50 a 65 anos. Os resultados estão apresentados em gráficos ou tabelas com informações de frequências absoluta e relativa. A esses dados, seguiu-se a análise interpretativa dos resultados de cada questão. As respostas dos sujeitos-entrevistados, bem como a localização destes estão registradas em 233 cartogramas linguísticos. Acredita-se que as palavras refletem a história dos sujeitos, confirmando que para a expressão linguística são exigidos fatores internos e estes estão associados a fatores externos à linguagem. Assim, a língua, conforme o espaço, variação diatópica, sofre variações. Toda a dinamicidade da língua é evidenciada sobretudo no léxico, nível linguístico que melhor expressa a mobilidade das estruturas sociais, o qual reflete a maneira como a sociedade vê e representa o mundo. Ao final da pesquisa, mostrou-se o quadro da diversidade linguística na região, constatando-se a variação semântico-lexical na ReNAT. Enfim, a tese registrou a realidade linguística dos cinco municípios que compõem a região pesquisada, com relação ao léxico utilizado pelos sujeitos-entrevistados. Sabe-se que a área pesquisada tem dimensões pequenas, mas, ainda assim, revela sua importância para os estudos sociogeolinguísticos, pois expressa a situação real de uso da linguagem do sujeito num espaço e momento determinado, e também denota as características sócio-histórico-culturais de uma comunidade linguística. / This thesis aims to identify the semantic and lexical norm of five counties of the North region of the High Tietê- ReNAT, in the state of São Paulo, and it is based on the dialectological, geolinguistic and sociogeolinguistic studies. The premise of the research, which is the ancient Vila de Nossa Senhora da Conceição dos Guarulhos, is currently composed of five counties: Guarulhos, Arujá, Santa Isabel, Mairiporã and Nazaré Paulista. It is located in the Great São Paulo area, except for Nazaré Paulista, that is situated in the micro region of Atibaia. The origin of the region composed of five counties, the corpus of this research goes back to the epoch of the foundation of São Paulo. Three counties are situated in the region of High Tietê, to the north of the river which takes the same name, that is why it is called ReNAT. This thesis has its fundamentals on the linguistic works featured by the dialectological and sociogeolinguistic studies focusing on the semantic and lexical aspect. The theory has been based on linguistic studies which have helped develop essays on Dialectology, Geolinguistic; Variational, Sociolinguistc; Interactional Sociolinguistic, Semantics and Lexicology. Besides the quantitative treatment of data, as of the studies of Muller, we have prioritized the approach of the lexical and semantic aspects, based on Pottier and Rastier, stemming from the conception of norm by the theory of Coseriu. Based on the recent methodological procedures of Geolinguistic and Sociogeolinguistic, 202 questions of the Semantic-Lexical (QSL) questionnaire of the ALIB project have been applied as well as the 31 questions of the questionnaire lexical-semantic of the Atlas of the São Paulo city (ALESP), created by the Grupo de Pesquisa em Dialetologia e Geolinguistica(GPDG) of the University of São Paulo. The interviews have been carried out in loco, that is, on the 6 places of research where the five counties belong to. The 233 questions of the 2 questionnaires were applied to 24 subjects of both genre- male and female- in two age brackets: from 18 to 30 and 50 to 65 years old. The results are presented in tables, graphs with information of absolute and relative frequency. To this data, followed the interpretative analysis of the results of each question. The answers of the interviewee- subjects are registered in 233 linguistic cartograms. It is believed that the words reflect the story of the individuals, confirming that to the linguistic expression are demanded the internal factors which are associated to the external factors of the language. Thus, language according to space, suffers variation and all this dynamism is evidenced on the lexicon- the linguistic level that better expresses the mobility of the social structures, which reflects the way the society sees and represents the world. A the end of this research, we have shown the picture of linguistic diversity of the aimed region by proving the variation of the ReNAT. At last, this research has registered the linguistic reality of the five counties that compose the region as to the lexicon used by the subjects interviewed. The studied area has small dimensions, but, even so, it reveals great importance to socio-geo-linguistic studies , for, they express the real usage of language in a certain space and time as well as the socio-historical and cultural features of a linguistic community.

The aims of this study were to examine a) whether the family-centered intervention method Auditory Verbal Therapy (AVT) has had an effect on the levels of empowerment of caregivers of children with CI; and b) whether the parents feeling most empowered have a continual habit of reading frequently with their child and have children who achieve higher scores on lexical-semantic tasks; c) whether the empowerment questionnaire “Att vara förälder” (“Being a parent”) is an appropriate assessment tool to evaluate intervention intending to empower the caregivers of children with hearing impairment. Vocabulary was used as a way to gauge the effectiveness of the method. Perceived empowerment of 23 parents was assessed with “Att vara förälder” (“Being a parent”) along with an informal conversation about the questionnaire. In addition, lexical-semantic ability of 11 children (age 5;1-11;8) was assessed with the BNT and the Semantic Feature Test for evaluation if the level of empowerment would affect vocabulary level. Overall the caregivers reported high levels of empowerment. Duration of intervention (range 6 months – 2 years or more) and levels of empowerment corresponded significantly positive. Further, a more active parent scored higher on empowerment than did the parent less active in intervention, as indicated by the self-reports. Qualitative data from the conversation revealed that many of the parents felt that the AVT intervention had helped them to feel more empowered. The results for lexical-semantic ability showed a large variability in the group, not significantly correlated to parents’ level of empowerment. The children older than eight years performed at stanine 5 and over on the BNT. The younger children did not score above stanine 4. In conclusion, the present study represents a first step towards applying empowerment as an instrument for the evaluation of family-centered intervention. Based on our results we argue that all children receiving a CI and their families would benefit from being provided with the possibility for prolonged intervention periods. / Syftet med denna studie var att undersöka a) om den familjebaserade interventionsmetoden Auditory Verbal Therapy (AVT) har haft effekt på känslan av empowerment hos föräldrar till barn med CI; och b) om de föräldrar med högst känsla av empowerment har som vana att ofta läsa för sina barn och har barn som presterar högt på testning av ordförråd; c) om enkäten ”Att vara förälder” är ett användbart verktyg för att utvärdera intervention som har som mål att öka känslan av empowerment hos vårdnadshavare till barn med hörselnedsättning. Bedömning av ordförråd användes som ett sätt att undersöka metodens effektivitet. 23 föräldrar fyllde i en empowerment-enkät ”Att vara förälder” och deltog sedan i ett informellt samtal med författarna till studien. Vidare bedömdes lexikal-semantisk förmåga hos 11 barn (ålder 5;1-11;8) med BNT och Särdragstestet med syfte att undersöka om nivån av empowerment påverkar ordförråd. Överlag hade vårdgivarna en hög känsla av empowerment. Interventions-längd (mellan 6 månader – 2 år eller mer) korrelerade signifikant positivt med empowerment. Därutöver framkom att den i interventionen mer aktiva föräldern erhöll ett högre resultat avseende empowerment, jämfört med den föräldern som varit mindre aktiv, enligt självskattningsdata. Kvalitativa data från det informella samtalet tydliggjorde att föräldrarna upplever att interventionen med AVT har förstärkt deras känsla av empowerment. Resultaten varierade stort vad gällde lexikal-semantisk förmåga, vilket inte korrelerade statistiskt med föräldrarnas nivå av empowerment. Barnen äldre än åtta år presterade stanine 5 eller över. De yngre barnen presterade inte över stanine 4. Sammanfattningsvis representerar denna studie ett första steg i ledet att implementera empowerment som ett utvärderingsinstrument i familjebaserad intervention. Baserat på resultaten i vår studie dras slutsatsen att alla barn som får CI skulle, tillsammans med sina familjer, gagnas av att få möjligheten till en långvarig familjebaserad interventionsinsats.

Esta tesis describe la variación conceptual en terminología. Entendemos por variación conceptual el proceso cognitivo que conduce a cambios graduales en un concepto y se manifiesta lingüística y semánticamente en grados diferentes de equivalencia entre los sentidos de una unidad léxica o entre los sentidos de sus variantes léxico-semánticas. Este estudio se basa en los fundamentos de la Teoría Comunicativa de la Terminología (TCT) (Cabré, 1999), en la teoría del término (Averboukh, 2005) y en la teoría de variación léxico-semántica (Karcevski, 1926 en Zviagintsev (ed.), 1965; Kury³owicz, 1955; Vinogradov, 1944; Smirnitsky, 1954; Ajmanova, 1957/2004; Nikitin 1974; Shmelev 1973/2008; Ufimtseva: 1986/2002; Solntsev, 1984, 1998, entre otros). Es un trabajo teórico, descriptivo y cualitativo que combina los postulados de la lingüística estructural y cognitiva y dos perspectivas del análisis del léxico: la semasiológica y la onomasiológica. La parte empírica de este estudio se basa en el método de estudio de casos e incluye el análisis de tres tipos de casos. En el caso A se comprueba que la situación prototípica de una acción nombrada por una unidad léxica nominal deverbal se proyecta en otros tipos de situaciones, conservando el Esquema nuclear o concepto básico. En el caso B se constata que una unidad léxica potencialmente polisémica actualiza diferentes significados y sentidos en el discurso especializado con dos tipos de relación entre ellos: intersección (polisemia irregular interdominio o intradominio) e inclusión (polisemia regular intradominio o interdominio). Se demuestra también que el comportamiento sintáctico y semántico del término en el discurso puede revelar pistas de la variación conceptual del mismo. Y en el caso C se demuestra que los expertos conceptualizan y categorizan sus objetos de estudio de maneras diversas, usando diversas estrategias cognitivas en los discursos que construyen. / This thesis describes conceptual variation in Terminology. By conceptual variation we understand the cognitive process leading up to gradual changes in a concept and which can be observed in different degrees of equivalence among senses of a lexical unit or among senses of the related lexical-semantic variants in discourse.This study is based on the Communicative Theory of Terminology (Cabré, 1999), the Theory of the Term (Averboukh, 2005), and the Theory of Lexical-Semantic Variation (Karcevski, 1926 in Zviagintsev (ed.), 1965; Kury³owicz, 1955; Vinogradov, 1944; Smirnitsky, 1954; Ajmanova, 1957/2004; Nikitin 1974; Shmelev 1973/2008; Ufimtseva: 1986/2002; Solntsev, 1984, 1998, etc.). It is a theoretical, descriptive, and qualitative study, which combines principles of Structural and Cognitive Linguistics and the semasiological and onomasiological perspectives of lexical analysis. The empirical part of the research consists of three cases following the case study methodology.In Case A, we see that the prototypical situation of an action named by a deverbal noun is mapped onto different kinds of situations preserving the Nuclear Scheme or basic concept. In Case B, it is proven that a potentially polysemic lexical unit activates various meanings and senses in specialized discourse, thus establishing two types of relations between them: intersection (inter- and intradomain irregular polysemy) and inclusion (inter- and intradomain regular polysemy). It is also demonstrated that the syntactic and semantic behaviour of terminological units in discourse can provide clues about conceptual variation. In Case C, it is confirmed that experts conceptualize and categorize their objects of study in different ways and construe their discourse using different cognitive strategies.

Esta tese, com o intuito de contribuir para uma reflexão em torno da história da formação da língua portuguesa no Brasil, propõe como objetivo geral realizar um estudo do léxico no município de Cáceres-MT, tendo como base a discussão sobre manutenção, tendência à manutenção, desuso, tendência ao desuso e neologismo semântico de unidades lexicais extraídas de um manuscrito oitocentista. Os objetivos específicos são os seguintes: (i) compreender a história social da Capitania de Mato Grosso e do município de Cáceres, a partir das informações constantes no manuscrito Memoria, e aspectos que envolvam as condições de produção do documento e a biografia do autor; (ii) levantar o léxico do manuscrito, com recorte nos substantivos e adjetivos para servir de base na seleção das unidades lexicais a serem testadas in loco, e investigar a acepção registrada no documento das unidades lexicais, caracterizando, assim, o léxico do período oitocentista; (iii), fazer um cotejo lexicográfico abrangendo dicionários gerais dos séculos XVIII ao XXI; (iv) testar e identificar, a partir do corpus oral constituído por meio de pesquisa de campo na região urbana cacerense, o grau de manutenção, tendência à manutenção, desuso, tendência ao desuso e neologismo semântico em relação às unidades lexicais e suas respectivas acepções registradas no manuscrito. Dessa forma, toma-se como corpus de língua escrita de análise o manuscrito oitocentista Memoria sobre o plano de guerra offensiva e deffensiva da Capitania de Matto Grosso e, a partir das unidades lexicais selecionadas e extraídas dele, realizou-se a pesquisa de campo para o recolhimento do corpus de língua oral. Antes dessa recolha, tendo como base teórico-metodológica as disciplinas de Dialetologia e de Geolinguística, selecionou-se a localidade (município de Cáceres - MT) e os informantes (total de dezesseis); elaborou-se o questionário semântico-lexical, considerando fundamentalmente a proposta apresentada pelo Comitê Nacional do Projeto ALiB (2001); e realizou-se a pesquisa de campo e as transcrições das entrevistas. Para análise de natureza semântico-lexical dos corpora, recorreu aos estudos lexicográficos e lexicológicos. Tomando por base os resultados do estudo realizado, constatou-se que na realidade linguística do informante cacerense encontram-se unidades que já integravam o léxico oitocentista da língua portuguesa escrita no Brasil, ou seja, há uma memória semântico-lexical que se mantém no sistema lexical, provavelmente, devido às condições sócioculturais do município de Cáceres, Mato Grosso, cuja população, em grande parte, por quase duzentos anos, viveu na área rural. Todavia, vislumbrou-se um certo equilíbrio entre a manutenção do léxico oitocentista sem deixar de lado a inovação e o mecanismo polissêmico constitutivo do léxico. / This thesis aims to contribute for a reflection on the history of Brazilian Portuguese language formation by proposing a study on the lexicon in the municipality of Cáceres, State of Mato Grosso, based on a discussion on the maintenance, the tendency to maintain, the disuse, the tendency to disuse and the semantic neologism of lexical units extracted from an eighthundredth manuscript. The specific goals of the study are the following: (i) understand the social history of the Mato Grosso Captainship and the municipality of Cáceres from the information available in the manuscript Memoria, and from aspects involving the conditions of production of the document and the authors biography; (ii) survey the lexicon of the manuscript, taking nouns and adjectives as the basis in the selection of lexical units to be tested in loco and investigate the meaning of lexical units registered in the document, thus characterizing the lexicon of the eight-hundredth period; (iii) carry out a lexicographical comparison including general dictionaries from the 18th to 21th centuries; (iv) test and identify, from the oral corpus built through the field work in the urban region of Cáceres, the degree of maintenance, the tendency to maintain, the disuse, the tendency to disuse and the semantic neologism regarding the lexical units and their respective meanings recorded in the manuscript. FFIn In order to achieve these goals, we take the eight-hundredth manuscript Memoria sobre o plano de Guerra offensive e deffensiva da Capitania de Matto Grosso [Memoir on the Offensive and Defensive War Plan of Matto Grosso Captainship] as a written language corpus for analysis and from the lexical units extracted and selected from this work we carried out field work to collect an oral language corpus. Before collecting this material, the courses Dialectology and Geolinguistics were used as theoretical and methodological basis for the selection of the site (municipality of Cáceres, State of Mato Grosso) and the informants (a total of sixteen). We then prepared a semantic-lexical questionnaire essentially considering the proposal presented by the National Project Committee (ALiB, 2001) and carried out the field research and the transcription of the interviews. Lexicographical and lexicological studies were used in the analysis of the lexical-semantic nature of the corpora. Building on the results of the study, we found out that the linguistic reality of the Cáceres informant showed units already comprised in the eight-hundredth lexicon of written Portuguese language in Brazil, that is, there is a semantic-lexical memory remaining in the lexical system, probably due to the sociocultural conditions of the municipality of Cáceres, State of Mato Grosso, where, for almost two hundred years, most of the population lived in the rural area. Nonetheless, a certain balance between the maintenance of the eight-hundredth lexicon was conceived without leaving aside innovation and the polysemic mechanism constituting the lexicon.
