In Section 4, we implement some of the existing models and compare their performance on our test set.
of these operations, we have, for each query q ∈ Q, a set of triplets (l, f l , c u,l ) where l is a language, f l is the count of clicks for l (which we obtained through the urls in language l), and c u,l is the count of unique urls in language l. The resulting table T 3 associates queries with languages, but also contains a lot of noise.
