  We present an easy-to-use and fast toolkit, namely VnCoreNLP---a Java NLP
annotation pipeline for Vietnamese. Our VnCoreNLP supports key natural language
processing (NLP) tasks including word segmentation, part-of-speech (POS)
tagging, named entity recognition (NER) and dependency parsing, and obtains
state-of-the-art (SOTA) results for these tasks. We release VnCoreNLP to
provide rich linguistic annotations to facilitate research work on Vietnamese
NLP. Our VnCoreNLP is open-source and available at:
