Zusammenfassung
This paper pursues two related goals: First, we establish a conceptual link between chunk-based syntactic structures as typically assumed in shallow parsing approaches, as opposed to principle-based syntactic structures as assumed in theoretical linguistics research. This conceptual link emerges from the study of configurational vs. non-configurational languages, and the observation of diverse strategies for ambiguity resolution across this spectrum of (non-)configurational language types.
Second, we show how shallow analyses as usually employed in practical NLP applications can be defined to deliver full-fledged syntactic representations, by designing an architecture for f-structure projection from chunk-based syntactic analysis.
In line with our two-fold goal we will show that principles for f-structure projection from chunks are similar -- modulo specific attachment constraints -- to the analysis of non-configurational languages. Our investigation offers theoretical insight into the kind of abstraction (i.e. underspecification) employed in shallow analysis, and how it can be formalised.
