http://www.mriquestions.com/meaning-of-weighting.html WebThe TF-IDF based IR system first builds an inverted index with TF and IDF values of terms. TF-IDF is superior in pre-season recall compared to other weighted schemes and it is treated as the de facto method for comparing higher performance. TF-IDF is used as a dominant weighting scheme for system, and also widely used in text mining application.
