Understanding TF IDF (term frequency - inverse document frequency)

tf-idf stands for Term Frequency - Inverse Document Frequency. It is a 2 dimensional data matrix where each term denotes the relative frequency of a particular word in a particular document as compared to other documents. This is a widely used metric in Text Mining and Information retrieval
