However, when the corpus is the entire web, direct IDF calculation is impossible and values must instead be estimated. Most available datasets provide values for term count (TC) meaning the number of times a certain term occurs in the entire corpu...

Using Suffix Arrays to Compute Term Frequency and Document Frequency for All Substrings in a Corpus

Bigrams and trigrams are commonly used in statistical natural language processing; this paper will describe techniques for working with much longer ngrams. Suffix arrays were first introduced to compute the frequency and location of a substring (ngram) in a sequence (corpus) of length N . To compute frequencies over all N(N+1)/2 substrings in a corpus, the substrings are grouped into a manageab...
