Incremental Processing and Syntactic Disambiguation of Extrapositions

Extrapositions are discontinuous constructions of German where constituents are extraposed into the Nachfeld. This paper describes an incremental parsing strategy for the syntactic disambiguation of different kinds of extrapositions. The proposed model proceeds on the assumption that extrapositions will be modeled by the discourse analysis. Parallelism constraints between the source sentence and the extraposed constituents are claimed to govern all possible interpretations induced by extrapositions.
