Yandex Finally Catches the Long-Tailed Queries
March 7, 2017
One of the happiest moments in a dog’s life is when, after having spent countless hours spinning in circles, is when they catch their tail. They wag for joy, even though they are chomping on their own happiness. When search engines were finally programmed to handle long-tailed queries, that is queries with a lot of words such as a question, people’s happiness was akin to a dog catching their tail. Google released RankBrain to handle long-winded ad NLP queries, but Yandex just released their own algorithm to handle questions, “Yandex Launches New Algorithm Named Palekh To Improve Search Results For Long-Tail Queries” from AIRS Association.
Yandex is Russia’s most-used search engine and in order to improve the user experience, they released Palekh to better process long-tail queries. Palekh, like RankBrain, will bring the search engine closer to understanding the natural language or the common vernacular. Yandex decided on the name Palekh, because the Russian city of the same name has a firebird on its coat of arms. The firebird has a long-tail, so the name fits perfectly.
Yandex handles more than 100 million queries per day that fall under the long-tail query umbrella. When asked if Yandex based Palekh on RankBrain, Yandex only responded that the two algorithms are similar in their purposes. Yandex also uses machine learning to build neural networks to build a smarter search engine:
Yandex’s Palekh algorithm has started to use neural networks as one of 1,500 factors of ranking. A Yandex spokesperson told us they have “managed to teach our neural networks to see the connections between a query and a document even if they don’t contain common words.” They did this by “converting the words from billions of search queries into numbers (with groups of 300 each) and putting them in 300-dimensional space — now every document has its own vector in that space,” they told us. “If the numbers of a query and numbers of a document are near each other in that space, then the result is relevant,” they added.”
Yandex is one of Google’s biggest rivals and it does not come as a surprise that they are experimenting with algorithms that will expand machine learning and NLP.

Hi, I do agree your points you’ve presented on this post. Dog are always become one of our friends.For this reason, most people would buy kinds of dog collars to build the link between the pet, such as training dog collar
