Noun phrase chunking is an important and useful task in many natural language processing
applications. It is studied well for English, however with Vietnamese it is still an open problem. This paper
presents a Vietnamese Noun Phrase chunking approach based on Conditional random fields (CRFs) models.
We also describe a method to build Vietnamese corpus from a set of hand annotated sentences. For
evaluation, we perform several experiments using different feature settings. Outcome results on our corpus
show a high performance with the average of recall and precision 82.72% and 82.62% respectively. ?? 2009
