Term Frequency-Inverse Document Frequency (TF-IDF) is a statistical measure used to evaluate the importance of a word in a document relative to a collection of documents (corpus). It combines two components: term frequency, which counts how often a term appears in a document, and inverse document frequency, which assesses how common or rare a term is across the corpus.
