Additionally, we should assign more weight to translation pairs that fulfil the strict criteria in sub-corpora of larger size K. For instance, if we detect that two words have identical frequency distributions and have fulfilled all the criteria from Subsection 2.2 in a sub-corpus consisting of a few millions items, that evidence should be more important than detecting that the two words could be extracted from a sub-corpus comprising only a few sentences.
for each potential translation pair t i j we assign a corresponding overall score c t i j .
