Part Of Speech Tagging and Chunking with HMM and CRF

Abstract

In this paper we propose an approach to Part of Speech (PoS) tagging using a com-bination of Hidden Markov Model and er-ror driven learning. For the NLPAI joint task, we also implement a chunker using Conditional Random Fields (CRFs). The results for the PoS tagging and chunking task are separately reported along with the results of the joint task. 1
