Has machine translation improved? some historical comparisons.
John G. B. Hutchins · 2003
The common assertion that MT systems have improved over the last decades is examined by informal comparisons of translations produced by operational systems in the 1960s, 1970s and 1980s and of translations of the same source texts produced by some currently available commercial and online systems. The scarcity of source and target texts for earlier systems means that the conclusions are consequently tentative and preliminary.
