Exploiting Similarities among Languages for Machine Translation

Por • 27 sep, 2013 • Category: Ciencia y tecnología

Dictionaries and phrase tables are the basis of modern statistical machine translation systems. This paper develops a method that can automate the process of generating and extending dictionaries and phrase tables. Our method can translate missing word and phrase entries by learning language structures based on large monolingual data and mapping between languages from small bilingual data. It uses distributed representation of words and learns a linear mapping between vector spaces of languages. Despite its simplicity, our method is surprisingly effective: we can achieve almost 90% precision@5 for translation of words between English and Spanish. This method makes little assumption about the languages, so it can be used to extend and refine dictionaries and translation tables for any language pairs.

Why Are Spy Researchers Building a ‘Metaphor Program’?

«The Metaphor Program will exploit the fact that metaphors are pervasive in everyday talk and reveal the underlying beliefs and worldviews of members of a culture,» declared an open solicitation for researchers released last week. A spokesperson for IARPA declined to comment at the time. IARPA wants some computer scientists with experience in processing language in big chunks to come up with methods of pulling out a culture’s relationship with particular concepts.»They really are trying to get at what people think using how they talk,» Benjamin Bergen, a cognitive scientist at the University of California, San Diego, told me. Bergen is one of a dozen or so lead researchers who are expected to vie for a research grant that could be worth tens of millions of dollars over five years, if the team scan show progress towards automatically tagging and processing metaphors across languages.
