ABSTRACT

Natural languages are the most important aspect of human life for communication. Natural Language Processing (NLP) is an important research area and application in computer science and computational linguistics, which explores how a computer can be used to understand and manipulate the text or speech of natural languages to do useful things. A small number of research or applications of NLP has been done for North-East (NE) languages in India. In this paper, we discuss the five most important as well as one of the major applications of NLP which are developed for NE natural languages and frequently used in human life namely, Electronic Dictionary (E-dictionary), Machine Translation (MT), Part of Speech Tagging (POST), Wordnet and Word Sense Disambiguation (WSD). These applications are very helpful and form an intermediate and necessary step towards implementation of higher applications of NLP. Since NE is a multilingual region in India; therefore these applications will be basically helpful for NE people as well as other people of India and abroad. The main purpose of this paper is to explore the importance, techniques, features of E-dictionary, MT, POST, Wordnet and WSD and to review the existing works of these applications developed for NE natural languages in India.
