Interesting remark by Marissa. Google has been working on automatic translation in general but also want to work on query translation. In the past I worked on this topic and participated in one of the conferences in this area, CLEF.in reference to:
""Imagine what it would be like if there was a tool built into the search engine which translated my search query into every language and then searched the entire world’s websites," she says. "And then invoked the translation software a second and third time – to not only then present the results in your native language, but then translated those sites in full when you clicked through.”"
