L’objectif de ce mémoire est de mettre en lumière la mise en forme, la réception et la transmission de 2S 7,1-17 à l’intérieur du débat qui a présentement cours autour de la rédaction deutéronomiste, ainsi que de vérifier le lien possible de ce texte avec l’évolution de la pensée théologique juive issue de l’édition deutéronomiste. Notre recherche commence par établir un texte hébreu de travail fiable grâce à la critique textuelle. L’analyse syntaxique nous permet ensuite de proposer une traduction qui soit la plus fidèle possible au texte hébreu retenu afin de mieux comprendre le sens du texte dans sa langue originale. Nous abordons, dans le troisième chapitre, la question des différentes sources littéraires ayant pu servir à la composition du texte de 2S 7,1-17. L’exploration plus détaillée de quelques pistes qui sont apparues à la suite de la critique des sources et de la réception du texte de 2S 7,1-17 par le(s) Chroniste(s), nous permet de constater qu’à l’intérieur des traditions textuelles hébraïques, la prophétie de Nathan a évolué de façon significative dans le parcours des différentes traditions de relecture. À partir des quatres étapes de recherches, nous dégageons les éléments qui pourraient être mis en lien avec les théories existantes dans le cadre de l’histoire deutéronomiste et mettons en lumière les forces et les faiblesses des solutions proposées. Les résultats de la recherche nous permettent de penser que l’intégration de la prophétie de Nathan dans la trame historique s’expliquerait par la nécessité d’éclairer une suite d’événements selon diverses perspectives théologiques. Ce n’est qu’à partir des conditions exiliques que nous aurions le texte de 2S 7,1-17 le plus tardif offrant une réflexion sur la première histoire d’Israël. Dans ce sens, la prophétie de Nathan prendrait toute sa valeur et son extension bien au-delà de la seule histoire personnelle de David ou de Salomon. / The principal objective of this thesis is to elucidate the source materials, the reception and the transmission of 2S 7,1-17 inside the debate concerning the Deuteronomic History, as well as to verify the possible link of the text with the evolution of the Jewish theology coming from the Deuteronomic edition. Our research begins with textual criticism in order to establish a reliable text in the Hebrew language. Then a syntactic analysis allows us to propose an accurate translation and to better understand the meaning of the text in its original language. Taking into account the results from these two first chapters, we then deal with the question concerning the different literary sources which lie behind the text of 2S 7,1-17. A more detailed exploration of some issues ensuins the source criticism and the study of the reception of 2S 7,1-17 by the Chronicler(s), show that inside the Hebrew literal traditions, the prophecy of Nathan evolved significantly in different traditions. Based on the four steps of research, we identify the elements that could be linked with the theories existing in the debate of the Deuteronomic History, and highlight the forces and the weaknesses of the proposed solutions. The research results allow us to think that the integration of the prophecy of Nathan into history could be explained by the necessity to clarify a sequence of events according to the diverse theological perspectives. It is in the conditions of the Exile that we have the latest text of 2S 7,1-17 offering a reflection on the first history of Israel. In this meaning, the prophecy of Nathan takes all its value and its extension beyond only the personal history of David or of Solomon.

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. / Semantic role annotation is a process that aims to assign labels such as Agent, Patient, Instrument, Location, etc. to actants or circumstants (also called arguments or adjuncts) of predicative lexical units. This process often requires the use of rich lexical resources or corpora in which sentences are annotated manually by linguists. The automatic approaches (statistical or machine learning) are based on corpora. Previous work was performed for the most part in English which has rich resources, such as PropBank, VerbNet and FrameNet. These resources were used to serve the automated annotation systems. This type of annotation in other languages for which no corpora of annotated sentences are available often use FrameNet by projection. Although a resource such as FrameNet is necessary for the automated annotation systems and the manual annotation by linguists of a large number of sentences is a tedious and time consuming work. We have proposed an automated system to help linguists in this task so that they have only to validate annotations proposed. Our work focuses on verbs that are more likely than other predicative units (adjectives and nouns) to be accompanied by actants realized in sentences. These verbs are specialized terms of the computer science and Internet domains (ie. access, configure, browse, download) whose actantial structures have been annotated manually with semantic roles. The actantial structure is based on principles of Explanatory and Combinatory Lexicology, LEC of Mel’čuk and appeal in part (with regard to semantic roles) to the notion of Frame Element as described in the theory of frame semantics (FS) of Fillmore. What these two theories have in common is that they lead to the construction of dictionaries different from those resulting from the traditional theories. These manually annotated verbal units in several contexts constitute the specialized corpus that our work will use. Our system designed to assign automatically semantic roles to actants is based on rules and classifiers trained on more than 2300 contexts. We are limited to a restricted list of roles for certain roles in our corpus have not enough examples manually annotated. In our system, we addressed the roles Patient, Agent and destination that the number of examples is greater than 300. We have created a class that we called Autre which we bring to gether the other roles that the number of annotated examples is less than 100. We subdivided the annotation task in the identification of participant actants and circumstants and the assignment of semantic roles to actants that contribute to the sense of the verbal lexical unit. We parsed, with Syntex, the sentences of the corpus to extract syntactic informations that describe the participants of the verbal lexical unit in the sentence. These informations are used as features in our learning model. We have proposed two techniques for the task of participant detection: the technique based in rules and machine learning. These same techniques are used for the task of classification of these participants into actants and circumstants. We proposed to the task of assigning semantic roles to the actants, a partitioning method (clustering) semi supervised of instances that we have compared to the method of semantic role classification. We used CHAMELEON, an ascending hierarchical algorithm.

L’analyse sémiotique de l’architecture domestique a pour but de voir comment se manifestent, à travers le langage architectural, les comportements codés qui remplacent la communication linguistique, en postulant qu'il y a un déterminisme de l'architecture par les valeurs macro-sociales, et que le signe architectural doit être considéré comme un marqueur anthropologique. L’approche pluridisciplinaire qui allie des champs aussi divers que l’architecture, la sémiologie et l’anthropologie, a pour ambition de contribuer d’une part, à la sémiotique de l’architecture en proposant une méthodologie pour l’analyse et le découpage d’un corpus architectural, et d’une autre, d’élargir le champ de la géographie urbaine à de nouvelles disciplines, et enfin, de proposer une lecture inédite du paysage urbain à Beyrouth à travers l’étude comparative de deux typologies architecturales. L’approche sémiotique proposée peut être appliquée en tant qu’outil de la géographie urbaine à des corpus architecturaux ou des pans du tissu urbain afin d’appréhender les mécanismes de production et d’obsolescence des formes, et par extension de la ville. / The purpose of a semiotic analysis of architecture is to see how non verbal codes manifest themselves through the architectural language, based upon the idea that such a language is conditioned by macro-social values, and therefore the architectural sign should be considered as an anthropological marker. This multi-disciplinary approach combining different fields such as architecture, semiotics and anthropology, is aimed on one hand at contributing to semiotics by proposing a methodology for the analysis of an architectural corpus, and on the other hand, to broadening the field of urban geography to new disciplines, and finally, to providing a new analysis of Beirut’s urban fabric through the comparative case study of two architectural typologies. The proposed semiotic approach can be applied as a tool of urban geography to architectural corpuses and urban fabrics in order to understand the mechanisms of production and obsolescence of form.

This study delves into the syntactic notion of subject relation in Shona with the aim of characterizing and defining it. This is done through analysing data collected from two of the Shona speaking provinces in Zimbabwe, namely, Harare and Masvingo. The data collection procedures involved the tape recording of oral interviews as well as doing selective listening to different speeches. The data were then analysed using the projection principle, noun phrase movement transformational rule as well as the selectional principles established for the subject relation in the other well researched natural languages. The research found out that there is no one single rule that can be used to determine the subject of every possible Shona sentence. One has to make use of all the seven selectional principles established in the well-researched natural languages. The research managed to assess the applicability of the selectional rules in different sentences. The rules were then ranked according to their reliability in determining the subjects of each of the various Shona sentences. It also came to light that the Shona subject relation has a number of sub-categories as a result of the various selectional rules involved in determining them. These were also ranked in a hierarchy of importance as they apply in the language. For instance, whilst some are assigned to their host words at the deep structure or underlying level of syntax, some are assigned at the surface structure level and can be shifted easily. It also emerged that the freedom of the subject relation in the language varies with the sub-category of the relation. It came to light as well that in Shona both noun phrases (NPs) and non-NPs are assigned the subject role. / African Languages / D. Litt. et Phil. (African Languages)

Cette étude a pour objectif la description syntaxique et sémantique des constructions transitives non locatives à un complément d'objet direct en grec moderne : N0 V N1. Nous nous sommes appuyée sur le cadre théorique de la grammaire transformationnelle de Zellig S. Harris et sur le cadre méthodologique du Lexique-Grammaire, défini par Maurice Gross et développé au Laboratoire d'Automatique Documentaire et Linguistique. À partir de 16 560 entrées verbales morphologiques, nous procédons à la classification des constructions transitives non locatives, à partir de 24 classes distinctes, sur la base de critères formels posés. Un inventaire de 2 934 emplois verbaux à construction transitive non locative à un complément d'objet direct a été ainsi produit et scindé en neuf classes. Parmi ces emplois, 1 884 sont formellement décrits dans 9 tables de lexique-grammaire établies : plus précisément, il s'agit de celles qui impliquent des constructions à un complément d'objet direct illustrant les concepts « apparition » (table 32GA), « disparition » (32GD), objet « concret » (32GC), « partie du corps » (32GCL), substantif « humain » (32GH), substantif avec « pluriel obligatoire » (32GPL). En outre, la transformation passive est largement interdite pour les emplois verbaux recensés dans la table 32GNM, alors que les tables 32GCV et 32GRA regroupent des verbes acceptant une transformation à verbe support. Nous présentons l'application des données linguistiques recensées dans le traitement automatique des langues naturelles (TALN), avec la conversion automatique des tables en automates à états finis récursifs, suivie de nos suggestions sur leur applicabilité à la traduction en français et à l'enseignement du grec moderne (langue maternelle ou étrangère) : acquisition/apprentissage / The current research aims to provide a syntactic and semantic analysis of Modern Greek transitive non-locative constructions with one direct object: N0 V N1. Our study is based on the syntactic framework of the Transformational Grammar defined by Zellig S. Harris. We followed the Lexicon-Grammar methodology framework developed by Maurice Gross and elaborated at the LADL (Laboratoire d'Automatique Documentaire et Linguistique). Based on 16 560 morphological verbal entries, we proceeded to the classification of transitive non-locative constructions. On the basis of formal criteria we divided them into 24 distinct classes that formed an inventory of 2 934 transitive non-locative verbal uses with one direct object. Among them, 1 884 verbal uses were split into nine classes and they were formally described in 9 lexicon-grammar tables established for this purpose. More precisely, these structures include a direct object referring to the following concepts: “appearance” (32GA table), “disappearance” (32GD), “concrete” object (32GC), “body part” (32GCL), “human” object (32GH), and “obligatory plural” (32GPL). Likewise, the passive transformation is largely blocked in the 32GNM table, while the 32GCV and 32GRA tables regroup verbs accepting a support verb transformation. We present the linguistic data application in Natural Language Processing (NLP), by means of automatic tables conversion into recursive transition network automata. Moreover, we set forth our remarks on their applicability in translation from Modern Greek to French as well as in language learning/teaching (Modern Greek as first or second language)

The main goal of this master thesis is introduction and investigation of extended version of jumping automata and grammars. New versions are primarily focused on bioinformatic applications - DNA computing. This thesis examine their power and other properties of new models and makes comparison with existing computer science models. Then thesis demontrates practical applications, specifically amino acid and protein detections inside DNA sequence and makes comparision with existing tools in DNA computing for example Mark´s probabilistic models.

This PhD thesis deals with the use of structural methods of objects identification for industrial robots operation. First, the present state of knowledge in the field is described, i.e. the whole process of objects recognition with the aid of common methods of the syntactic analysis. The main disadvantage of these methods is that is impossible to recognize objects whose digitalized image is corrupted in some ways (due to excessive noise or image disturbances), objects are therefore deformed. Further, other methods for the recognition of deformed objects are described. These methods use structural description of objects for object recognition, i.e. methods which determine the distance between attribute descriptions of images. The core part of this PhD thesis begins in Chapter 5, where deformation grammars, capable of description of all possible object deformations, are described. The only complication in the analysis is the ambiguity of the deformation grammar, which lowers the effectiveness of the analysis. Further, PhD thesis deals with the selection and modification of a proper parser, which is able to analyze a deformation grammar effectively. Three parsers are described: the modified Earley parser, the modified Tomita parser and the modified hybrid LRE(k) parser. As for the modified Earley’s parser, ways of its effective implementation are described. One of the necessary parts of the object recognition is providing the invariances, which this PhD thesis covers in detail, too. Finally, the results of described algorithms are mentioned (successfulness and speed of deformed objects recognition) and suggested testing environment and implemented algorithms are described. In conclusion, all determined possibilities of deformation grammars and their results are summarized.

[pt] Esta tese investiga os fatores semânticos e sintáticos que afetam a codificação do objeto direto anafórico (ODA) no português brasileiro (PB). O ODA pode ser um DP pleno [+ definido], um clítico acusativo, um pronome tônico ou um elemento nulo (cuja natureza é controversa na teoria linguística). Busca-se: (i) avaliar como fatores semânticos (animacidade, especificidade e gênero conceitual), sintáticos (função sintática) e pertinentes à interface sintaxe/semântica (papel temático) afetam a codificação da retomada, em diferentes contextos sintáticos (sentenças simples e ilha sintática) e/ou discursivos (respostas a perguntas QU e complementação de narrativas curtas ou conversas informais); (ii) verificar a influência da escolarização nas estratégias de codificação do ODA; e (iii) discutir a natureza das formas nulas produzidas. O aporte teórico parte da concepção de língua veiculada no Programa Minimalista (CHOMSKY,1995. 2005) e da perspectiva de produção trazida do modelo de computação gramatical em tempo real (CORRÊA, 2006; 2008; CORRÊA; AUGUSTO, 2007; em diante) no tratamento das questões ligadas à acessibilidade relativa do antecedente a ser retomado (ARIEL, 2001; ARNOLD, 2010; BOCK; WARREN, 1985; SANDERS; GERNSBACHER, 2004), quando da codificação gramatical do enunciado (LEVELT, 1989). Parte-se da hipótese de que a produção de ODAs é função das condições de processamento às quais o falante está submetido e que propriedades semânticas e sintáticas do antecedente afetam sua acessibilidade relativa, impondo restrições à codificação de sua retomada. Seis experimentos de produção eliciada são reportados. O contexto sintático influenciou a acessibilidade dos antecedentes, retomados predominantemente por DPs completos entre sentenças no discurso; e por formas mínimas (pronominais e elementos nulos), quando em sentenças complexas. Os efeitos de animacidade e de especificidade sugerem que o pronome tônico seja default para antecedentes acessíveis [+animado; +específico], enquanto o nulo o é para [-animados; mais ou menos específico], corroborando achados da literatura com produção espontânea. O gênero conceitual não foi decisivo para a retomada anafórica, mas pareceu aumentar a especificidade de antecedentes cujo gênero conceitual era conhecido. O papel temático, por si só, não é decisivo para a forma da retomada anafórica. Entretanto, a possibilidade de o elemento nulo recuperar um fato/evento descrito anteriormente o compatibiliza com uma alternativa ao clítico sentencial. O grau de escolaridade dos participantes elevou as taxas de clíticos acusativos, especialmente com antecedentes [+animado] (como alternativa aos pronomes tônicos), evidenciando a interferência da língua escrita sobre a língua falada, bem como a produtividade dessa forma para falantes com alto grau de escolaridade. A função sintática do antecedente não interferiu no ODA. A ocorrência do elemento nulo em contextos de ilha corrobora a visão de que este não seja uma variável no PB. À luz do modelo de computação em tempo real, considera-se que as condições de acesso do antecedente determinam a natureza da forma nula: se a representação da estrutura sintática do antecedente se mantiver ativa na memória de trabalho, este pode ser recuperado como uma elipse, a ser restaurada na interface semântica; se apenas seus traços phi ou a representação semântica de seu antecedente são acessíveis, ODA é codificado como pro. / [en] This thesis investigates the semantic and syntactic factors that affect the encoding of the anaphoric direct object (ADO) in Brazilian Portuguese (BP). The ADO can be a full DP [+definite], an accusative clitic, a stressed pronoun, or a null element (whose nature is controversial in linguistic theory). This research aims to: (i) investigate how the semantic properties (animacy, specificity and conceptual genre) of the antecedent, its syntactic function and factors pertaining to the syntax/semantic interface (thematic role) affect the encoding of the ADO in different syntactic contexts (simple sentences and syntactic island) and/or discourse (answers to WH-questions and continuations of short narratives or informal conversations); (ii) verify the influence of schooling in the strategies of ADO encoding; and (iii) discuss the nature of the null forms produced. The theoretical background incorporates the conception of language conveyed in the Minimalist Program (CHOMSKY, 1995; 2005) and an approach to issues regarding the relative accessibility of the antecedent to be resumed (ARIEL, 2001; ARNOLD, 2010; BOCK; WARREN, 1985; SANDERS; GERNSBACHER, 2004) in the grammatical encoding of a sentence (LEVELT, 1989), in the light of an on-line model of grammatical computation (CORREA, 2006; 2008; CORREA; AUGUSTO, 2007) The working hypothesis is that the production of the ODA is a function of particular processing conditions and that the semantic and syntactic properties of the antecedent affect its relative accessibility, imposing restrictions on its resumption. Six elicited production experiments are reported. The syntactic context influenced the accessibility of the antecedents, predominantly recovered by full DPs, when between-sentences in the discourse; and by minimal forms (pronominals and null elements) in complex sentences. The effects of animacy and of specificity corroborate spontaneous production data, suggesting that the full pronoun is the default option for [+animated; +specific], while the null form is the default option for [-animated; +- specific] antecedents. The conceptual genre of the antecedent was not decisive for a particular form of encoding, but it seemed to enhance the specificity of the antecedent whose conceptual gender was known. The thematic role, by itself, does not determine the form of anaphoric resumption. However, the possibility of the null resumption of an fact/event previously mentioned makes it compatible with an alternative to the sentential clitic. Schooling increased the rates of accusative clitics, especially with [+animated] antecedents (as an alternative to tonic pronouns), showing the interference of the written language on the spoken language, as well as the productivity of this form for educated speakers. The syntactic function of the antecedent did not affect ADO production. The occurrence of the null element in island contexts corroborates the view that the null element is not a variable in BP. It is argued, in the light of the on-line model, that the accessibility of the antecedent determines the nature of null element: if the representation of the syntactic structure of the antecedent is still active in working memory, it can be retrieved as an ellipsis, to be restored at the semantic interface; if it is the phi features of the antecedent or the semantic representation of its referent that remain available, ADO is encoded as a pro.
