[Corpora-List] Google's translations

Thu Mar 11 13:18:27 UTC 2010

I have three comments:

1. The text by Kant contains a lot of anaphoric pronouns. From Google's
translation it is obvious that their system does not perform any pronoun
resolution (or at least none that works better than a random baseline).
However, there exist German to English translation engines on the market
that incorporate such components.

2. Consider the following extract from Kant's text:

"wo [jedermann]SUBJ, [der sonst in allen übrigen Dingen unwissend
ist]REL_CL,
[sich]REFLX [ein entscheidendes Urteil]OBJ [anmaßt]PRED"

A simple relative clause separates subject from object and predicate. The
completely garbled translation that Google delivers can serve as a textbook
example to illustrate how n-gram models (even 9-grams in this case) of
syntax fail to cope with long range dependencies.

3. Another interesting experiment is to let Google translate the German word
"Ufer" (meaning "bank", but only in the waterside sense) into Czech. This
gives "banky", which means "bank", but only in its financial sense. This can
be explained by the observation that Google always uses English as
interlingua (Ufer --> bank --> banky). If you directly translate e.g.
Spanish to French you will get exactly the same result as when you first
translate Spanish into English, and then translate the English output into
French.
Obviously, even for Google it is too costly to generate and maintain 52 * 51
= 2651 translation models for all the supported language pairs. Or is it
that they have found that X to English to Y always performs better than X to
Y because there is so much more data available between English and X or Y
than between X and Y?
