Extraposition: A Case Study in German Sentence Realization

We profile the occurrence of clausal extraposition in corpora from different domains and demonstrate that extraposition is a pervasive phenomenon in German that must be addressed in German sentence realization. We present two different approaches to the modeling of extraposition, both based on machine learned decision tree classifiers. The two approaches differ in their view of the movement ope...

Machine-learned contexts for linguistic operations in German sentence realization

We show that it is possible to learn the contexts for linguistic operations which map a semantic representation to a surface syntactic tree in sentence realization with high accuracy. We cast the problem of learning the contexts for the linguistic operations as classification tasks, and apply straightforward machine learning techniques, such as decision tree learning. The training data consist ...

Complementizers and Finite Verbs in German Sentence Structure

In this paper, 1 we discuss a new approach to the analysis of the verb second phenomenon in German. The analysis builds on empirical generalizations previously studied in the GB framework. It accounts for the movement of nite verbs without lexical rules, traces or a feature inv(erted), and it eliminates the Head-Filler-Schema for unbounded dependencies. We show that a lexical theory of the elem...

Measures for Term and Sentence Relevances: an Evaluation for German

Terms, term relevances, and sentence relevances are concepts that figure in many NLP applications, such as Text Summarization. These concepts are implemented in various ways, though. In this paper, we want to shed light on the impact that different implementations can have on the overall performance of the systems. In particular, we examine the interplay between term definitions and sentencesco...
