Plural semantics for natural language understanding : a computational proof-theoretic approach
(2005)
The semantics of natural language plurals poses a number of intricate problems – both from a formal and a computational perspective. In this thesis I investigate problems of representing, disambiguating and reasoning with plurals from a computational perspective. The work defines a computationally suitable representation for important plural constructions, proposes a tractable resolution algorithm for semantic plural ambiguities, and integrates an automatic reasoning component for plurals. My solution combines insights from formal semantics, computational linguistics and automated theorem proving and is based on the following main ideas. Whereas many existing approaches to plural semantics work on a model-theoretic basis using higher-order representation languages I propose a proof-theoretic approach to plural semantics based on a flat firstorder semantic representation language thus showing that a trade-off between expressive power and logical tractability can be found. The problem of automatic disambiguation of plurals is tackled by a deliberate decision to drastically reduce recourse to contextual knowledge for disambiguation but rely instead on structurally available and thus computationally manageable information. A further central aspect of the solution lies in carefully drawing the borderline between real ambiguity and mere indeterminacy in the interpretation of plural noun phrases. As a practical result of my computational proof-theoretic approach to plural semantics I can use my methods to perform automated reasoning with plurals by applying advanced firstorder theorem provers and model-generators available off-the shelf. The results are prototypically implemented within the two logic-oriented natural language understanding applications DRoPs and Attempto. DRoPs provides an automatic plural disambiguation component for uncontrolled natural language whereas Attempto works with a constructive disambiguation strategy for controlled natural language. Both systems provide tools for the automated analysis of technical texts allowing users for example to automatically detect inconsistencies, to perform question answering, to check whether a conjecture follows from a text or to find equivalences and redundancies.

In 2015, the last work of Günter Grass appeared: Vonne Endlichkait (On Finiteness). This offers the opportunity to recall the highly personal style of this great German author. The whole book can be described as an artistic triad, consisting of short prose pieces, poems and drawings, most of them dealing with old age and death. The following linguistic and literary aspects are dealt with: genres and text types, the semiotic relations between prose, poetry and drawings, allusions to poets and philosophers, the representation of spoken and dialect German, syntactic constructions, semantics, and especially metaphorical processes. Finally, the article discusses some stylistic features which are typical of Grass's writing.
The research focuses on the narrative verbalization of mental reactions to the official announcement of 9 November 1989 stating that citizens of the GDR were henceforth permitted to travel to the West. This announcement differs from the type of unexpected information which is readily believable and comprehensible, to which we respond with interjections (change-of-state tokens: oh, ach, ach so) and certain formulations (das glaub ich, ich verstehe). Respondents from both East and West Berlin represented in the "Wende-Korpus" reacted from the cognitive perspective with mistrust and incomprehension, and from the emotional perspective with surprise, which was reflected both in syntactic structure and in the frequent use of metaphors. The report was more frequently interpreted as a joke than as a real event.
Článek ukazuje příklad užití určitých klíčových metod a konceptů při analýze dialogů v literárním textu. Pro analýzu byl vybrán krátký, ale dramatický dialog mezi manželským párem v povídce Christopha Heina (1989) "Die Vergewaltigung". Navrhujeme, aby analýza zahrnovala pět kroků: 1. procedurální organizace dialogu (střídání mluvčích atd.), 2. témata a způsob, jak jsou nová témata zaváděna, 3. řečové akty (ne pouze ilokuce), 4. vytváření sociální identity a sociálních vztahů mezi účastníky, 5. interaktivní modalita. Na závěr je poukázáno na rozdíly mezi dialogy v literárních textech a jejich ekvivalenty v reálném životě.
O objetivo deste trabalho é divulgar e analisar os resultados de uma pesquisa realizada em três instituições paulistanas nas quais se ensina/aprende alemão como língua estrangeira. A pesquisa teve como objetivo geral investigar as crenças que alunos de língua alemã mantêm em relação a seu processo de aprendizagem. O corpus, coletado a partir de questionários e entrevistas, revelou muitas dessas crenças, referentes, por exemplo, à aprendizagem de gramática. Os resultados também apontam para a existência de uma relação entre as crenças e a adoção de determinadas estratégias de aprendizagem. Durante a análise, buscou-se identificar possíveis origens para as crenças detectadas, bem como os efeitos potenciais das mesmas sobre a aprendizagem da língua alemã. No presente artigo, algumas das crenças constatadas no estudo serão descritas e analisadas em relação a pressupostos teóricos e metodológicos da didática de línguas estrangeiras para o ensino de gramática.
Organized by Sabine Schulte im Walde (University of Stuttgart) and Eva Smolka (University of Konstanz) as part of the 39th Annual Conference of the German Linguistic Society (DGfS) held at the Saarland University in Saarbrücken, Germany, the workshop aimed “to shed light on the interaction of constituent properties and compound transparency across languages and disciplines integrating linguistic, psycholinguistic, corpus-based and computational studies”. The workshop brought together researchers from linguistics, psycholinguistics, and natural language processing and comprised 11 contributed talks, framed by two invited talks by Gary Libben and Marco Marelli. Most of the slides are available from the workshop’s homepage at “http://www.ims.uni-stuttgart.de/events/dgfs-mwe-17/program.html”.
