TF-IDF

🚀 Term Frequency - Inverse Document Frequency

This is an algorithm for generating keywords (tags) for a document.

Concept

We can split the algorithm into two parts:

• TF (= term frequency): how often does a word occur in one document
• IDF (= inverse document frequency): the higher this score, the less frequently the term occurs in other documents (words such as 'a' or 'the' get a low IDF score)
