Representing text chunks
Erik F. Tjong Kim Sang, Jorn Veenstra · 1999
Dividing sentences in chunks of words is a useful preprocessing step for parsing, information extraction and information retrieval.(l~mshaw and Marcus, 1995) have introduced a "convenient" data representation for chunking by converting it to a tagging task.In this paper we will examine seven different data representations for the problem of recognizing noun phrase chunks.We will show that the the data representation choice has a minor influence on chunking performance.However, equipped with the most suitable data representation, our memory-based learning chunker was able to improve the best published chunking results for a standard data set.
