Natural Language Processing is an upcoming field in the area of text mining. As text is an unstructured source of information, to make it a suitable input to an automatic method of information extraction it is usually transformed into a structured format. Part of Speech Tagging is one of the preprocessing steps which perform semantic analysis by assigning one of the parts of speech to the given word. In this paper we had discussed various models of supervised and unsupervised technique, experimentally compared the results obtained in models of Supervised CRF and Supervised Maximum Entropy Model. We had also discussed the problem occurring with supervised part of speech tagging.
