Term Frequency (TF) Where: frtd = raw frequency of term t in document d Document Frequency – DF Global term weighting method, where terms occurring in more documents are considered as more relevant. DFt=∑d 1n 1t ∈d0t i / nd Term Frequency – Inverse Document Frequency – TF-IDF The most common weight computation schema applied with Vector Space Model is the…
