Russian search giant Yandex has announced today that it has acquired ‘social newspaper’ service The Tweeted Times as part of a push to integrate more social data into its search results.

The Tweeted Times is similar to Paper.li, in that it generates a ‘newspaper’ on the Web containing stories shared by people you follow on Twitter. It doesn’t appear to do anything particularly unique, and its iPad app faces stiff competition from the likes of Flipboard. The team behind it have joined Yandex to work on boosting its search and content services with information from social networks.

The Tweeted Times will continue to operate post-acquisition. According to CrunchBase, its team, which also operated under the name Semantic Dimension, is based in Moscow, Zurich and San Francsico.

In 2010, Yandex generated 64% of all search traffic in Russia and was the largest Russian Internet company by revenue. It floated on the NASDAQ earlier this year.
