Tf*idf is a numerical statistic used in information retrieval to
represent how important a specific word or phrase is to a given document.
TF*IDF Example
Consider a document containing 100 words wherein the word SEO appears 3 times.
The term frequency (i.e., tf) for SEO is then (3 / 100) = 0.03.
Now, assume we have 10 million documents and the word SEO appears in one thousand of these. Then, the inverse document frequency (i.e., idf) is calculated as log(10,000,000 / 1,000) = 4.
Thus, the Tf-idf weight is the product of these quantities: 0.03 * 4 = 0.12.
