Question Generation (QG) is the task of generating reasonable questions from a text. It is a relatively new research topic and has its potential usage in intelligent tutoring systems and closed-domain question answering systems. Current approaches include template or syntax based methods. This thesis proposes a novel approach based entirely on semantics.(More)
We are compiling a corpus of Dutch texts annotated with discourse structure and lexical cohesion, containing initially 80 texts from expository and persuasive genres. We are using this resource for corpus-based studies of discourse relations, discourse markers, cohesion, and genre differences. We are also exploring the possibilities of automatic text(More)
Textual coherence versus discourse structure Coherence is one of the most general and most widely discussed concepts in the study of text and discourse In spite or perhaps because of its central status the concept of coherence has many di erent and often incompatible de nitions and connotations For text linguistics or psycholinguistics with their focus on(More)
Prosody, particularly accent, aids comprehension by drawing attention to important elements such as the information that answers a question. A study using ERP registration investigated how the brain deals with the interpretation of prosodic prominence. Sentences were embedded in short dialogues and contained accented elements that were congruous or(More)
What is meaning, what is it for a sign to be meaningful, how can meaning best be analyzed, and in what sense is linguistic meaning proper or unique to language? Cognitive linguistics offers answers to these questions that challenge two traditional dogmas of linguistic theory, philosophy of language and cognitive science. However, although they have(More)
This paper considers linguistic evidence concerning the form of focussed representations of discourse referents and the linguistic means used to access such representations. It is argued that two forms of representation can be distinguished, one of which, explicit focus, is accessed via linguistic representations of discourse referents, whereas the other,(More)
This paper contributes to the question of which degree of complexity is called for in representations of discourse structure. We review recent claims that tree structures do not suffice as a model for discourse structure, with a focus on the work done on the Discourse Graphbank (DGB) of Wolf and Gibson (2005, 2006). We will show that much of the additional(More)
This study investigates the use of Same – a relation that connects the parts of a discontinuous discourse segment – in the Discourse Graphbank (Wolf et al., 2004). Our analysis reveals systematic deviations from the definition of the Same relation and a substantial number of confusions between Same and Elaboration relations. We discuss some methodological(More)
