O uso de corpora na análise da representação do discurso em tradução

Este artigo apresenta uma pesquisa sobre a representação do discurso ficcional embasado na gramática sistêmico - funcional proposta por Halliday e na Lingüística de Corpus, utilizando-se o software WordSmith Tools. A análise focaliza a metafunção ideacional, realizada pelo sistema de transitividade, focalizando os processos mentais e a relação lógico - semântica da projeção. O objetivo da pesquisa foi observar como os pensamentos das personagens de um corpus ficcional são representados através dos verbos de elocução THINK e PENSAR, buscando descrever padrões textuais nos três romances que compõem o corpus.

Qual a função dos corpora na descrição do léxico?

Variação das unidades fraseoterminológicas da culinária entre português brasileiro e português europeu

A criação de uniões, como a União Europeia e o Mercosul, o aumento do intercâmbio de mercadorias, de informações e conhecimentos, etc. estabelece novos trabalhos na área da Terminologia Científica e Técnica, tanto bilíngue como monolíngue, inclusive entre variantes de uma mesma língua, como o Português Brasileiro (PB) e o Português Europeu (PE), o que torna relevante o conhecimento das variantes fraseoterminológicas entre duas normas linguísticas para o especialista e para o tradutor. Sendo a Culinária uma área que proporciona vários tipos de intercâmbios, como linguístico, cultural, mercantil, etc. e, dessa forma, necessitando trocar conhecimentos, nosso estudo propõe, através de uma perspectiva interdisciplinar que engloba a Terminologia, numa ótica variacionista, a Fraseologia e a Linguística de Corpus, estabelecer critérios para identificar, emparelhar, contrastar e descrever as unidades fraseoterminológicas (UFT) da Culinária do PB e do PE, almejando, por conseguinte, estruturá-las numa ferramenta que seja útil aos especialistas, estudantes e tradutores dessa área. O desenvolvimento deste trabalho está organizado em sete capítulos. O primeiro, apresenta a Culinária, traçando um panorama histórico dessa área, e estabelece o mapa conceitual da Culinária que, além de servir para a organização das relações conceituais no dicionário, limita o universo da pesquisa. O segundo aborda a variação em Terminologia, bem como as principais tendências da Terminologia que aceitam a variação terminológica. O terceiro explana a Fraseologia, desde a língua corrente até à língua de especialidade, e estabelece os critérios para recolha dos candidatos a UFT da Culinária. O quarto apresenta brevemente a Linguística de Corpus e traça os caminhos seguidos para a constituição dos dois corpora textuais da Culinária, compostos de receitas culinárias e técnicas de preparo, os quais serviram para o levantamento da terminologia. O quinto trata da coleta e organização das unidades fraseoterminológicas da Culinária em PB bem como das respectivas variantes em PE e seu armazenamento em Base de Dados. O sexto, analisa a variação entre os pares de UFT selecionados para esse fim, descreve os contrastes detectados, e apresenta uma tipologia contrastiva dessas UFT variantes entre PB e PE. O sétimo apresenta o projeto do Dicionário Fraseológico Contrastivo de Culinária: Português Brasileiro - Português Europeu, descrevendo suas partes e o sistema de remissivas. Com base nas reflexões teóricas e na análise dos dados recolhidos, pudemos, além de identificar, emparelhar e descrever as diferentes formas assumidas do discurso da Culinária pelas UFT, chegar a um projeto de dicionário fraseoterminológico, cuja microestrutura possibilitará, mais que compreender o significado da UT, encontrar elementos para produzir um texto, visando, desse modo, as necessidades reais de tradutores e redatores, que carecem de recursos para o uso adequado das UFT presentes nas línguas de especialidade. Os resultados obtidos reafirmam que a variação terminológica é um fenômeno inerente aos domínios de especialidade, assim como às línguas naturais em que estão inseridas e, portanto, não deve ser ignorado na hora de elaborar dicionários terminológicos.

How can clusters help in the product type choice? The case of a specialized retail store

This work project (WP) is a study about a clustering strategy for Sport Zone. The general cluster study’s objective is to create groups such that within each group the individuals are similar to each other, but should be different among groups. The clusters creation is a mix of common sense, trial and error and some statistical supporting techniques. Our particular objective is to support category managers to better define the product type to be displayed in the stores’ shelves by doing store clusters. This research was carried out for Sport Zone, and comprises an objective definition, a literature review, the clustering activity itself, some factor analysis and a discriminant analysis to better frame our work. Together with this quantitative part, a survey addressed to category managers to better understand their key drivers, for choosing the type of product of each store, was carried out. Based in a non-random sample of 65 stores with data referring to 2013, the final result was the choice of 6 store clusters (Figure 1) which were individually characterized as the main outcome of this work. In what relates to our selected variables, all were important for the distinction between clusters, which proves the adequacy of their choice. The interpretation of the results gives category managers a tool to understand which products best fit the clustered stores. Furthermore, as a side finding thanks to the clusterization, a STP (Segmentation, Targeting and Positioning) was initiated, being this WP the first steps of a continuous process.

Antiepileptika bei Frauen im gebärfähigen Alter und in der Schwangerschaft : Vergleich der Fachinformationen in Deutschland und der Schweiz mit dem aktuellen Wissensstand [Antiepileptics in women of childbearing age and during pregnancy : Comparison of specialized information with the current state of knowledge in Germany and Switzerland].

BACKGROUND: Healthcare professionals regularly read the summary of product characteristics (SmPC) as one of the various sources of information on the risks of drug use in women of childbearing age and during pregnancy. The aim of this article is to present an overview of the teratogenic potential of various antiepileptic drugs and to compare these data with the information provided by the SmPCs. METHODS: A literature search on the teratogenic risks of 19 antiepileptic agents was conducted and the results were compared with the information on the use in women of childbearing age and during pregnancy provided by the SmPCs of 38 commercial products available in Switzerland and Germany. RESULTS: The teratogenic risk is discussed in all available SmPCs. Quantification of the risk for birth defects and the numbers of documented pregnancies are mostly missing. Reproductive safety information in SmPCs showed poor concordance with risk levels reported in the literature. Recommendations concerning the need to monitor plasma levels and possibly perform dose adjustments during pregnancy to prevent treatment failure were missing in five Swiss and two German SmPCs. DISCUSSION: The information regarding use in women of childbearing age and during pregnancy provided by the SmPCs is heterogeneous and poorly reflects the current state of knowledge. Regular updates of SmPCs are warranted in order for these documents to be of reliable use for health care professionals.

Opioid poisoning and availability of specialized medical care in Ontario, 2002-2006

The prescription of opioid analgesics has risen sharply in North America over the past two decades. This increase has been accompanied by a rise in overdoses. The present study draws on administrative data collected from emergency department contacts to describe the epidemiology of opioid overdose in Ontario b~tween 2002 and 2006 and to examine the role of regional variation in availability of specialist care. The number of poisonings increased from 1250 (10.9 per 100,000) in FY2002 to 1816 (15.2 per 100,000) in FY2005. Local concentration of specialist physicians was significantly associated with the incidence of opioid overdose, inversely at most levels of availability, but positively at very high levels. Regional variation in incidence was also associated with demographics, median family income, and the rate of other drug poisonings. Policy options for limiting opioid-related harms are limited, but improvements in monitoring and clinical management may prove valuable.

What are the components of humanized childbirth in a highly specialized hospital? : an organizational case study

Many studies have focused on the concept of humanization of birth in normal pregnancy cases or at low obstetric risk, but no studies, at our knowledge, have so far specifically focused on the humanization of birth in both high-risk, and low risk pregnancies, in a highly specialized hospital setting. The present study thus aims to: 1) define the specific components of the humanized birth care model which bring satisfaction to women who seek obstetrical care in highly specialized hospitals; and 2) explore the organizational and cultural dimensions which act as barriers or facilitators for the implementation of humanized birth care practices in a highly specialized, university affiliated hospital in Quebec. A single case study design was chosen for this thesis. The data were collected through semi-structured interviews, field notes, participant observations, selfadministered questionnaire, relevant documents, and archives. The samples comprised: 11 professionals from different disciplines, 6 administrators from different hierarchical levels within the hospital, and 157 women who had given birth at the hospital during the study. The performed analysis covered both quantitative descriptive and qualitative deductive and inductive content analyses. The thesis comprises three articles. In the first article, we proposed a conceptual framework, based on Allaire and Firsirotu’s (1984) organizational culture theory. It attempts to examine childbirth patterns as an organizational cultural phenomenon. In our second article, we answered the following specific question: according to the managers and multidisciplinary professionals practicing in a highly specialized hospital as well as the women seeking perinatal care in this hospital setting, what is the definition of humanized care? Analysis of the data collected uncovered the following themes which explained the perceptions of what humanized birth was: personalized care, recognition of women’s rights, humanly care for women, family-centered care,women’s advocacy and companionship, compromise of security, comfort and humanity, and non-stereotyped pregnancies. Both high and low risk women felt more satisfied with the care they received if they were provided with informed choices, were given the right to participate in the decision-making process and were surrounded by competent care providers. These care providers who humanly cared for them were also able to provide relevant medical intervention. The professionals and administrators’ perceptions of humanized birth, on the other hand, mostly focused on personalized and family-centered care. In the third article of the thesis, we covered the dimensions of the internal and external components of an institution which can act as factors that facilitate or barriers that prevent, a specialized and university affiliated hospital in Quebec from adopting a humanized child birthing care. The findings revealed that both the external dimensions of a highly specialized hospital -including its history, society, and contingency-; and its internal dimensions -including culture, structure, and the individuals present in the hospital-, can all affect the humanization of birth care in such an institution, whether separately, simultaneously or in interaction. We thus hereby conclude that the humanization of birth care in a highly specialized hospital setting, should aim to meet all the physiological, as well as psychological aspects of birth care, including respect of the fears, beliefs, values, and needs of women and their families. Integration of competent and caring professionals and the use of obstetric technology to enhance the level of certainty and assurance in both high-risk and low risk women are both positive factors for the implementation of humanized care in a highly specialized hospital. Finally, the humanization of birth care approach in a highly specialized and university affiliated hospital setting demands a new healthcare policy. Such policy must offer a guarantee for women to have the place of birth, and the health care professional of their choice as well as those, which will enable women to make informed choices from the beginning of their pregnancy.

Annotation syntaxico-sémantique des actants en corpus spécialisé

L’annotation en rôles sémantiques est une tâche qui permet d’attribuer des étiquettes de rôles telles que Agent, Patient, Instrument, Lieu, Destination etc. aux différents participants actants ou circonstants (arguments ou adjoints) d’une lexie prédicative. Cette tâche nécessite des ressources lexicales riches ou des corpus importants contenant des phrases annotées manuellement par des linguistes sur lesquels peuvent s’appuyer certaines approches d’automatisation (statistiques ou apprentissage machine). Les travaux antérieurs dans ce domaine ont porté essentiellement sur la langue anglaise qui dispose de ressources riches, telles que PropBank, VerbNet et FrameNet, qui ont servi à alimenter les systèmes d’annotation automatisés. L’annotation dans d’autres langues, pour lesquelles on ne dispose pas d’un corpus annoté manuellement, repose souvent sur le FrameNet anglais. Une ressource telle que FrameNet de l’anglais est plus que nécessaire pour les systèmes d’annotation automatisé et l’annotation manuelle de milliers de phrases par des linguistes est une tâche fastidieuse et exigeante en temps. Nous avons proposé dans cette thèse un système automatique pour aider les linguistes dans cette tâche qui pourraient alors se limiter à la validation des annotations proposées par le système. Dans notre travail, nous ne considérons que les verbes qui sont plus susceptibles que les noms d’être accompagnés par des actants réalisés dans les phrases. Ces verbes concernent les termes de spécialité d’informatique et d’Internet (ex. accéder, configurer, naviguer, télécharger) dont la structure actancielle est enrichie manuellement par des rôles sémantiques. La structure actancielle des lexies verbales est décrite selon les principes de la Lexicologie Explicative et Combinatoire, LEC de Mel’čuk et fait appel partiellement (en ce qui concerne les rôles sémantiques) à la notion de Frame Element tel que décrit dans la théorie Frame Semantics (FS) de Fillmore. Ces deux théories ont ceci de commun qu’elles mènent toutes les deux à la construction de dictionnaires différents de ceux issus des approches traditionnelles. Les lexies verbales d’informatique et d’Internet qui ont été annotées manuellement dans plusieurs contextes constituent notre corpus spécialisé. Notre système qui attribue automatiquement des rôles sémantiques aux actants est basé sur des règles ou classificateurs entraînés sur plus de 2300 contextes. Nous sommes limités à une liste de rôles restreinte car certains rôles dans notre corpus n’ont pas assez d’exemples annotés manuellement. Dans notre système, nous n’avons traité que les rôles Patient, Agent et Destination dont le nombre d’exemple est supérieur à 300. Nous avons crée une classe que nous avons nommé Autre où nous avons rassemblé les autres rôles dont le nombre d’exemples annotés est inférieur à 100. Nous avons subdivisé la tâche d’annotation en sous-tâches : identifier les participants actants et circonstants et attribuer des rôles sémantiques uniquement aux actants qui contribuent au sens de la lexie verbale. Nous avons soumis les phrases de notre corpus à l’analyseur syntaxique Syntex afin d’extraire les informations syntaxiques qui décrivent les différents participants d’une lexie verbale dans une phrase. Ces informations ont servi de traits (features) dans notre modèle d’apprentissage. Nous avons proposé deux techniques pour l’identification des participants : une technique à base de règles où nous avons extrait une trentaine de règles et une autre technique basée sur l’apprentissage machine. Ces mêmes techniques ont été utilisées pour la tâche de distinguer les actants des circonstants. Nous avons proposé pour la tâche d’attribuer des rôles sémantiques aux actants, une méthode de partitionnement (clustering) semi supervisé des instances que nous avons comparée à la méthode de classification de rôles sémantiques. Nous avons utilisé CHAMÉLÉON, un algorithme hiérarchique ascendant.

Criteria for the validation of specialized verb equivalents : application in bilingual terminography

Multilingual terminological resources do not always include valid equivalents of legal terms for two main reasons. Firstly, legal systems can differ from one language community to another and even from one country to another because each has its own history and traditions. As a result, the non-isomorphism between legal and linguistic systems may render the identification of equivalents a particularly challenging task. Secondly, by focusing primarily on the definition of equivalence, a notion widely discussed in translation but not in terminology, the literature does not offer solid and systematic methodologies for assigning terminological equivalents. As a result, there is a lack of criteria to guide both terminologists and translators in the search and validation of equivalent terms. This problem is even more evident in the case of predicative units, such as verbs. Although some terminologists (L‘Homme 1998; Lerat 2002; Lorente 2007) have worked on specialized verbs, terminological equivalence between units that belong to this part of speech would benefit from a thorough study. By proposing a novel methodology to assign the equivalents of specialized verbs, this research aims at defining validation criteria for this kind of predicative units, so as to contribute to a better understanding of the phenomenon of terminological equivalence as well as to the development of multilingual terminography in general, and to the development of legal terminography, in particular. The study uses a Portuguese-English comparable corpus that consists of a single genre of texts, i.e. Supreme Court judgments, from which 100 Portuguese and 100 English specialized verbs were selected. The description of the verbs is based on the theory of Frame Semantics (Fillmore 1976, 1977, 1982, 1985; Fillmore and Atkins 1992), on the FrameNet methodology (Ruppenhofer et al. 2010), as well as on the methodology for compiling specialized lexical resources, such as DiCoInfo (L‘Homme 2008), developed in the Observatoire de linguistique Sens-Texte at the Université de Montréal. The research reviews contributions that have adopted the same theoretical and methodological framework to the compilation of lexical resources and proposes adaptations to the specific objectives of the project. In contrast to the top-down approach adopted by FrameNet lexicographers, the approach described here is bottom-up, i.e. verbs are first analyzed and then grouped into frames for each language separately. Specialized verbs are said to evoke a semantic frame, a sort of conceptual scenario in which a number of mandatory elements (core Frame Elements) play specific roles (e.g. ARGUER, JUDGE, LAW), but specialized verbs are often accompanied by other optional information (non-core Frame Elements), such as the criteria and reasons used by the judge to reach a decision (statutes, codes, previous decisions). The information concerning the semantic frame that each verb evokes was encoded in an xml editor and about twenty contexts illustrating the specific way each specialized verb evokes a given frame were semantically and syntactically annotated. The labels attributed to each semantic frame (e.g. [Compliance], [Verdict]) were used to group together certain synonyms, antonyms as well as equivalent terms. The research identified 165 pairs of candidate equivalents among the 200 Portuguese and English terms that were grouped together into 76 frames. 71% of the pairs of equivalents were considered full equivalents because not only do the verbs evoke the same conceptual scenario but their actantial structures, the linguistic realizations of the actants and their syntactic patterns were similar. 29% of the pairs of equivalents did not entirely meet these criteria and were considered partial equivalents. Reasons for partial equivalence are provided along with illustrative examples. Finally, the study describes the semasiological and onomasiological entry points that JuriDiCo, the bilingual lexical resource compiled during the project, offers to future users.

Élaboration d'un corpus étalon pour l'évaluation d'extracteurs de termes

Ce travail porte sur la construction d’un corpus étalon pour l’évaluation automatisée des extracteurs de termes. Ces programmes informatiques, conçus pour extraire automatiquement les termes contenus dans un corpus, sont utilisés dans différentes applications, telles que la terminographie, la traduction, la recherche d’information, l’indexation, etc. Ainsi, leur évaluation doit être faite en fonction d’une application précise. Une façon d’évaluer les extracteurs consiste à annoter toutes les occurrences des termes dans un corpus, ce qui nécessite un protocole de repérage et de découpage des unités terminologiques. À notre connaissance, il n’existe pas de corpus annoté bien documenté pour l’évaluation des extracteurs. Ce travail vise à construire un tel corpus et à décrire les problèmes qui doivent être abordés pour y parvenir. Le corpus étalon que nous proposons est un corpus entièrement annoté, construit en fonction d’une application précise, à savoir la compilation d’un dictionnaire spécialisé de la mécanique automobile. Ce corpus rend compte de la variété des réalisations des termes en contexte. Les termes sont sélectionnés en fonction de critères précis liés à l’application, ainsi qu’à certaines propriétés formelles, linguistiques et conceptuelles des termes et des variantes terminologiques. Pour évaluer un extracteur au moyen de ce corpus, il suffit d’extraire toutes les unités terminologiques du corpus et de comparer, au moyen de métriques, cette liste à la sortie de l’extracteur. On peut aussi créer une liste de référence sur mesure en extrayant des sous-ensembles de termes en fonction de différents critères. Ce travail permet une évaluation automatique des extracteurs qui tient compte du rôle de l’application. Cette évaluation étant reproductible, elle peut servir non seulement à mesurer la qualité d’un extracteur, mais à comparer différents extracteurs et à améliorer les techniques d’extraction.

Analyse comparative de l'équivalence terminologique en corpus parallèle et en corpus comparable : application au domaine du changement climatique

Les travaux entrepris dans le cadre de la présente thèse portent sur l’analyse de l’équivalence terminologique en corpus parallèle et en corpus comparable. Plus spécifiquement, nous nous intéressons aux corpus de textes spécialisés appartenant au domaine du changement climatique. Une des originalités de cette étude réside dans l’analyse des équivalents de termes simples. Les bases théoriques sur lesquelles nous nous appuyons sont la terminologie textuelle (Bourigault et Slodzian 1999) et l’approche lexico-sémantique (L’Homme 2005). Cette étude poursuit deux objectifs. Le premier est d’effectuer une analyse comparative de l’équivalence dans les deux types de corpus afin de vérifier si l’équivalence terminologique observable dans les corpus parallèles se distingue de celle que l’on trouve dans les corpus comparables. Le deuxième consiste à comparer dans le détail les équivalents associés à un même terme anglais, afin de les décrire et de les répertorier pour en dégager une typologie. L’analyse détaillée des équivalents français de 343 termes anglais est menée à bien grâce à l’exploitation d’outils informatiques (extracteur de termes, aligneur de textes, etc.) et à la mise en place d’une méthodologie rigoureuse divisée en trois parties. La première partie qui est commune aux deux objectifs de la recherche concerne l’élaboration des corpus, la validation des termes anglais et le repérage des équivalents français dans les deux corpus. La deuxième partie décrit les critères sur lesquels nous nous appuyons pour comparer les équivalents des deux types de corpus. La troisième partie met en place la typologie des équivalents associés à un même terme anglais. Les résultats pour le premier objectif montrent que sur les 343 termes anglais analysés, les termes présentant des équivalents critiquables dans les deux corpus sont relativement peu élevés (12), tandis que le nombre de termes présentant des similitudes d’équivalence entre les corpus est très élevé (272 équivalents identiques et 55 équivalents non critiquables). L’analyse comparative décrite dans ce chapitre confirme notre hypothèse selon laquelle la terminologie employée dans les corpus parallèles ne se démarque pas de celle des corpus comparables. Les résultats pour le deuxième objectif montrent que de nombreux termes anglais sont rendus par plusieurs équivalents (70 % des termes analysés). Il est aussi constaté que ce ne sont pas les synonymes qui forment le groupe le plus important des équivalents, mais les quasi-synonymes. En outre, les équivalents appartenant à une autre partie du discours constituent une part importante des équivalents. Ainsi, la typologie élaborée dans cette thèse présente des mécanismes de l’équivalence terminologique peu décrits aussi systématiquement dans les travaux antérieurs.

The Challenges of didactics on scholar inclusion: specialized teachers perceptions

This study is a section of the GP-FOREESP - Formation of Human Resources and Learning in Special Education Group’s agenda. This Group is engaged in the development of researches with the intent to contribute on the process to universalize the access to school as well as on the improvement of education system that is currently available to the target population of Special Education. Nowadays, the inclusion process subject has been prioritized by that research group, as they consider that, along with other reasons, the efforts to establish an inclusive education system would be the unique alternative to solve the problem regarding the access to school, which is currently limited, and also to improve the quality on special education, since the level presented in the country is low. Guided by such premise, the present work is a supplementary project developed within the group extent to generate knowledge on school inclusion matter
