![]() ![]() TF-IDF use two statistical methods, first is Term Frequency and the other is Inverse Document Frequency. The tf-idf value increases in proportion to the number of times a word appears in the document but is often offset by the frequency of the word in the corpus, which helps to adjust with respect to the fact that some words appear more frequently in general. Let’s take an example, we have a string or Bag of Words (BOW) and we have to extract information from it, then we can use this approach. It is one of the most important techniques used for information retrieval to represent how important a specific word or phrase is to a given document. TF-IDF which stands for Term Frequency – Inverse Document Frequency. Now, you are searching for tf-idf, then you may familiar with feature extraction and what it is.
