... custom-made parallel corpus by automatically assembling it from documents taken from other parallel corpora. Although the general idea can be applied to any application that uses parallel corpora, ... Once the similarity is computed for each document in the parallel corpora, only the top N most similar documents are kept for training. They are an approximation of the domain(s) of the test ... tuned to a different test corpus as any other parameter. Alternatively, the document score can also be incorporated into the translation model, eliminating the need for thresholding. 4 CLIR Method...
