An Integrated Architecture for Shallow and Deep Processing
10 Proceedings of ACL-2002, Association for Computational Linguistics 40th Anniversary Meeting, July 7-12, Pages 441-448, Philadelphia, USA, o.A., 2002
We present an architecture for the integration of shallow and deep NLP components which is aimed at flexible combination of different language technologies for a range of practical current and future applications. In particular, we describe the integration of a high-level HPSG parsing system with different high-performance shallow components, ranging from named entity recognition to chunk parsing and shallow clause recognition. The NLP components enrich a representation of natural language text with layers of new XML meta-information using a single shared data structure, called the text chart. We describe details of the integration methods, and show how information extraction and language checking applications for realworld German text benefit from a deep grammatical analysis.
