Categorization in text mining means sorting documents into groups. Automatic document classification uses a combination of natural language processing (NLP) and machine learning to categorize customer reviews, support tickets, or any other type of text document based on their contents.

Simplest way to do text categorization is to use bag-of-words representation. Words/ n-grams of words in each document could be used as features. With this you can represent every document as vector in metric space. Subsequently, you can apply clustering to group documents that are similar in terms of content.

Text classification also known as text tagging or text categorization is the process of categorizing text into organized groups. By using Natural Language Processing (NLP), text classifiers can automatically analyze text and then assign a set of pre-defined tags or categories based on its content.

Supervised text classification is the preferred machine learning technique when the goal of your analysis is to automatically classify pieces of text into one or more defined categories.
