Term Frequency

Term Frequency (TF) refers to how often a specific word appears within a given document or text. It’s a way to measure the importance of a word in that document, with higher frequency indicating greater relevance to the content. For instance, if the word "sales" appears 10 times in a report, its term frequency is higher compared to a word that only appears once. TF is often used in text analysis and search engines to identify key topics or keywords, helping to understand what the document is mainly about.
