This thesis gives formal definitions of discourse-givenness, coreference and reference, and reports on experiments with computational models of discourse-givenness of noun phrases for English and German. Definitions are based on Bach's (1987) work on reference, Kibble and van Deemter's (2000) work on coreference, and Kamp and Reyle's Discourse Representation Theory (1993). For the experiments, the following corpora with coreference annotation were used: MUC-7, OntoNotes and ARRAU for Englisch, and TueBa-D/Z for German. As for classification algorithms, they cover J48 decision trees, the rule based learner Ripper, and linear support vector machines. New features are suggested, representing the noun phrase's specificity as well as its context, which lead to a significant improvement of classification quality. / Die vorliegende Arbeit gibt formale Definitionen der Konzepte Diskursgegebenheit, Koreferenz und Referenz. Zudem wird über Experimente berichtet, Nominalphrasen im Deutschen und Englischen hinsichtlich ihrer Diskursgegebenheit zu klassifizieren. Die Definitionen basieren auf Arbeiten von Bach (1987) zu Referenz, Kibble und van Deemter (2000) zu Koreferenz und der Diskursrepräsentationstheorie (Kamp und Reyle, 1993). In den Experimenten wurden die koreferenzannotierten Korpora MUC-7, OntoNotes und ARRAU (Englisch) und TüBa-D/Z (Deutsch) verwendet. Sie umfassen die Klassifikationsalgorithmen J48 (Entscheidungsbäume), Ripper (regelbasiertes Lernen) und lineare Support Vector Machines. Mehrere neue Klassifikationsmerkmale werden vorgeschlagen, die die Spezifizität der Nominalphrase messen, sowie ihren Kontext abbilden. Mit Hilfe dieser Merkmale kann eine signifikante Verbesserung der Klassifikation erreicht werden.

This dissertation investigates the interrelation between information structure and discourse structure. Information-structurally backgrounded material is here generally treated as being anaphoric in a very strict sense. It is argued that, apart from having more descriptive content, elements from the sentence background are not different from other types of anaphora: they are subject to the same locality restrictions and they must correspond to the same semantic types. The treatment of the sentence background as a monolithic and atomic unit is refuted. Instead it is argued that sentence backgrounds may be built up from smaller units which are linguistically realise as links and tails (in the sense of Vallduví, 1992). It is shown that links and tails play different roles with respect to the structure of discourse: linguistically realised links have to be bound by a discourse topic, while tails have to be bound by other salient referents within the discourse environment. / Este trabajo investiga la interrelación entre la estructura informativa y la estructura del discurso. El material del trasfondo lingüístico (background) de la oración se trata como una serie de elementos anafóricos en sentido estricto. Aunque tengan más contenido descriptivo, comparten las mismas características con otros tipos de anáfora en términos de restricciones de localidad y del tipo semántico. Se rechaza un tratamiento del background de la oración como una unidad atómica. En este trabajo se argumenta que el background se puede construir a partir de elementos más fundamentales, llamados links y tails (siguiendo Vallduví, 1992). Links y tails juegan un papel muy distinto con respecto a la estructura del discurso: los constituyentes realizados como links tienen que estar ligados por un tópico discursivo, mientras que los constituyentes realizados como tails necesitan estar ligados por otros referentes discursivos que estén salientes en el entorno del discurso.

Le présent travail propose d’examiner le projet phénoménologique de Jean-Luc Marion en le caractérisant comme une herméneutique de l’amour. Il s’agit, ce faisant, de trouver au sein des possibles de la phénoménologie de la donation une réponse aux deux principales objections qu’elle a reçu : l’objection herméneutique (Greisch, Grondin et autres) et l’objection théologique (Janicaud, Benoist et autres). En suivant le modèle de la phénoménologie du jeune Heidegger, la phénoménologie de la donation opère comme une herméneutique en tant qu’elle doit déchiffrer le sens énigmatique du phénomène saturée et elle ne le fait qu’en s’appropriant philosophiquement d’une idée théologique : l’idée de l’amour. L’amour en tant que Grundstimmung fonctionne comme puissance de phénoménalisation de la donation. / The present work aims to examine Marion’s phenomenological project by characterizing it as a hermeneutics of love. In doing so, I will try to find within the possibilities of the phenomenology of donation an answer to the two main objections it has received: the hermeneutic objection (Greisch, Grondin, and others) and the theological objection (Janicaud, Benoist, and others). Following the young Heidegger’s phenomenology, the phenomenology of givenness operates as a hermeneutics insofar as it must decipher the enigmatic sense of the saturated phenomenon and it does so only by philosophically appropriating a theological

This study aims to articulate on the basis of Jean-Luc Marion's philosophy a mystical interpretation of subjectivity. The first chapter follows Marion's reading of the history of metaphysics, in order to set-up the transcendental conditions of the mutual exclusion of God and the self. The second chapter takes up Marion's alternative to expand the field of philosophical rationality which metaphysics had limited. Marion proposes a phenomenology of givenness to overcome the limits of metaphysical thought. The final chapter attempts to establish a link between mysticism, understood in the specific sense of the primacy of the Good over Being, and the gifted, or the new figure of subjectivity. keywords : Jean-Luc Marion, history of metaphysics, phenomenology of givenness, saturated phenomenon, mystical theology
