For questions related to TF-IDF(Term Frequency — Inverse Document Frequency) a technique to quantify a word in documents

TF-IDF (Term Frequency-Inverse Document Frequency) is a statistical measure that evaluates how relevant a word is to a document in a collection of documents. This is done by multiplying two metrics: how many times a word appears in a document, and the inverse document frequency of the word across a set of documents i.e, weight based on its term frequency (TF) and inverse document frequency (IDF). The terms with higher weight scores are considered to be more important.
