The cross-language document similarity model requires a bilingual dictionary in the appropriate language pair.
we generated statistical dictionaries for 3 language pairs (from parallel corpora of the following sizes: 11K sentence pairs in English-Kannada, 54K in English-Hindi, and 14K in English-Tamil) using the GIZA++ statistical alignment tool (Och et al., 2003), with 5 iterations each of IBM Model 1 and HMM.
