Another feature of the “Queen” is that it takes into account also the meaning of other keywords for which people to pass it. “To the neural network can evaluate the semantic proximity of the query and the document she needs a huge amount of examples . Such examples give an impersonal search stats: what sites people go on requests and how much time you spend there. So if a person went to the page and was looking at it a while, most likely, it is close in meaning to the query. Using the search statistics of millions of people, “Yandex” learning to understand the semantic connection. For example, he will understand that the query “painting where the sky twisted”, it is about the painting by van Gogh, and the query “lazy cat from Mongolia” – Pallas” – said in a press release.

For us in “Yandex” today’s launch is as important technological breakthrough towards the dream of search that understands the users,” – said at the presentation of the new version of the search head of the relevance of linguistics of “Yandex” Alexander Safronov.
