TF-IDF (Term Frequency, Inverse Document Frequency) is a basic technique to compute the relevancy of a document with respect to a particular term. "Term" is a generalized element contains within a document. A "term" is a generalized idea of what a document contains. (e.g. a term can be a word, a phrase, or a concept).
