Term Frequency is abbreviated as TF-IDF. Records with an inverse Document Frequency. It’s the process of determining how relevant a word in a series or corpus is to a text. The meaning of a word grows in proportion to how many times it appears in the text, but this is offset by the corpus’s word frequency (data-set).
