Yandex Personalises Search

Yandex Personalises Search

MOSCOW, Dec. 12, 2012 (GLOBE NEWSWIRE) -- Yandex (Nasdaq:YNDX), one of the
largest European internet companies operating Russia's most popular search
engine and most visited website, has implemented search personalisation. Now
one of Europe's leading search engines will fetch search results and make
search suggestions based on the individual interests and preferences of each
of its users. Having searched for 'Harry Potter' on Yandex, a book lover will
see links to the book on top of the search results, while those who prefer the
film or the game will be directed to results related to their respective
interests. Personalised search is part of Yandex's new search platform,
Kaliningrad.

To understand the search intentions of its users, Yandex analyses their online
behaviour including their search history, clicks on search results and their
language preferences. The search engine uses this information to make search
suggestions and rank search results individually tailored for each user. A
football fan, for instance, will see in his personal search suggestions other
related queries typically made by football fans, while someone who enjoys
watching films online, will be offered links to streaming websites among other
search results. Personalised search significantly improves the quality of the
search experience for the user – they instantly reach their search goal and
save their time.

"Different people using similar key words in their searches are often looking
for something different. We found a way to apply our knowledge of each user to
offer them the best possible search result for their personal search
intentions. Personalised search individually tunes results for each and every
user based on what it knows about them from previous actions the user
performed online. It improves the quality of search results for about 75-80%
search queries," says Denis Rogachevsky, lead developer for Personalised
Search at Yandex.

Search personalisation is enabled by default for every active user of Yandex
Search. The more searches the user makes, the better results they receive. The
personalised search feature can be easily disabled in the search engine's
settings.

The current personalised search engine was preceded by the company's search
platform Reykjavik, launched last year, which delivered search results based
on the user's language preferences. After that, Yandex released a number of
products that made the search experience for its users more personalised – the
search engine started to add the user's previous searches and frequently
visited web sites to their search suggestions. Each of these innovations
became part of Yandex's personalised search engine and was implemented in its
latest edition – the Kaliningrad search platform.
