EBay uses machine learning techniques to translate listings

Historically, more than half of the sales through eBay Inc.'s online auction site are made overseas. There was a problem, though: Users on the site saw only listings posted in their preferred language. People could change their settings and browse the site in different languages, one at a time. But they had little visibility into products and goods listed in languages other than the selected one. With different sellers posting the same items in a variety of languages, this meant that individual users were only seeing a segment of all the listings for a given product.
