Document Classification Using Machine Learning Algorithms - A Review

Automatic classification of text document plays a vital area of research in the field of Text Mining (TM) ever since the explosion of online text information. The sources like digital libraries, emails, blogs, etc., make the rapid evolving growth of text documents in the digital era. In general the categorization of text document includes several field of interest like Information Retrieval (IR), Machine Learning (ML) and Natural Language Processing (NLP). Hence, this paper focuses on various research attempts which employ both supervised and unsupervised ML techniques for classifying a set of text documents into pre-defined category labels.
