"Google is working with technologies such as statistical machine translation, speech recognition and entity detection. The plan is to leverage what Google "owns" on the Web to learn as many words, and consequent word relations, as possible. That, he says, would enable intuitive, cognitive "conversations" to take place between searcher and search engine."

""We are on our way to learning from more than 1 trillion words procured from public Web pages, where others may have a billion," he says, adding, "there's no data like more data."
