Microsoft strikes search deals with Twitter, Facebook

22.10.2009
Microsoft has reached collaboration agreements with Twitter and Facebook to get their members' public status updates and messages indexed and presented in useful ways on the Bing search engine.

Yusuf Mehdi, senior vice president of Microsoft's Online Audience Business, made the announcement on stage at the Web 2.0 Summit in San Francisco.

The partnership with Twitter has it working with Microsoft to optimize how Bing crawls and indexes "tweets." Microsoft in turn will apply search algorithms to the Twitter messages, so that Bing users will not only be able to see a real-time feed of "tweets" but also rank them by how relevant they are to their query, Mehdi said.

"This is a big deal we've been working on for a long time," Mehdi said.

To rank "tweets" by relevance, a feature Microsoft calls "Best Match," Bing will take into consideration a number of factors, such as who are the authors of the messages based on a "social relevance" score Bing will assign to them, Mehdi said.

Bing will also evaluate the message's quality, noticing, for example, if it contains a link to an online article or Web page. It will also take into consideration how popular the message is by calculating how many times it has been "re-tweeted" by others.
