TF-IDF, bir sayfadaki belirli bir anahtar kelimenin önemini ölçmek için kullanılan frekans-ters belge frekansı anlamına gelir. Anahtar kelime yoğunluğunun aksine, sadece terimin sayısına bakmaz; ayrıca daha büyük bir sayfa kümesini analiz eder ve bu veya şu anahtar kelimenin ne kadar önemli olduğunu belirlemeye çalışır.
Örneğin, araba tamirinde, "lastik tamiri" terimi, "turboşarjlı motor tamiri" terimine göre daha önemli olma eğilimindedir - özellikle her arabanın lastikleri vardır ve sadece birkaç arabanın turbo motorları vardır. Bu yüzden, "lastik tamiri" terimi, araba tamiri hakkında konuşan daha büyük bir sayfa kümesinde kullanılmaktadır.
Bu, WebSite Denetimi'ndeki TF-IDF raporunun yakalayabileceği şeydir!
