Noun phrase chunking with APL2

Abstract

The identification of phrases in a sentence can be useful as a pre-processing step before attempting the full parsing. There is already much literature about finding simple non-recursive non-overlapping Noun Phrases. We have modified the learning paradigm CLOG [4] to produce transformation lists, and we arrived to several interesting conclusions about Noun Phrase chunking. IBM APL2 was used to build a prototype that was later rewritten in C++ for performance purposes.
