{wiki=Tf–idf}
TF-IDF stands for Term Frequency-Inverse Document Frequency. It's a statistical measure used primarily in information retrieval and text mining to evaluate the importance of a word in a document relative to a collection of documents, or corpus. The idea behind TF-IDF is to highlight words that are more significant in a particular document while downplaying words that appear frequently across many documents, which might not be as meaningful or informative.
