In Google Inc.’s vision of the future,
people will be able to translate documents instantly into the world’s
main languages, with machine logic, not expert linguists, leading the way.
Google’s approach, called statistical
machine translation, differs from past efforts in that it forgoes language
experts who program grammatical rules and dictionaries into computers.
Instead, they feed documents humans
have already translated into two languages and then rely on computers to
discern patterns for future translations.
While the quality is not perfect,
it is an improvement on previous efforts at machine translation, said Franz
Och, 35, a German who heads Google’s translation effort at its Mountain
View headquarters south of San Francisco.
“Some people that are in machine
translations for a long time and then see our Arabic-English output, then
they say, that’s amazing, that’s a breakthrough,” said Och.“And then
other people who have never seen what machine translation was ... they
read through the sentence and they say, the first mistake here in line
five -- it doesn’t seem to work because there is a mistake there.”
But for some tasks, a mostly correct
translation may be good enough.
Speaking over lunch this week in a
Google cafeteria famed for offering free, healthy food, Och showed a translation
of an Arabic Web news site into easily digestible English.
Two Google workers speaking Russian
at a nearby table said, however, that a translation of a news site from
English into their native tongue was understandable but a bit awkward.
Och, who speaks German, English and
some Italian, feeds hundreds of millions of words from parallel texts such
as Arabic and English into the computer, using United Nations and European
Union documents as key sources.
