In 21st Century, Data is considered as New Oil. Given the spurt of Globalisation followed by Digitization, the size of Data has grown to an extent where classification of Text has become an exacting task. In the myriad of uncertainties task of text classification using Machine Learning can be enriched using various pre-processing techniques like stemming, lemmatization but usage of “Term Frequency”- ‘Inverse Document Frequency’(TF-IDF) helps further to refinement of text data as TF-IDF produces feature values for training a classifier. To further improvise the classification process, comparison amid the machine learning classification algorithms has been presented in the paper.
