Wal-Mart Stores, Inc. (NYSE:WMT) has acquired mobile and social ad targeting company OneRiot. OneRiot will be integrated into Walmart Labs. OneRiot recently shifted their business model from a search portal to monetizing its real-time ad network. Now OneRiot provides its social targeting service for mobile ads within apps.

OneRiot has updated their search algorithm to include real-time data for link indexing and ranking.  Some of the search results from the real-time stream are powered by Digg and Twitter.  OneRiot’s Pulse stream uses a similar ranking system as Google PageRank.

The Pulse search algorithm has been around since OneRiot launched, but they have improved it since then.  Pulse’s results will be considered based on domain authority, timeliness, individual reputation, etc.  Pulse accounts for credible Twitter and Digg users.

“We’re also getting a lot of leverage from our Artificial Intelligence systems that constantly ‘learn’ how to improve the way we rank results,” stated the OneRiot Blog recently.

There are many companies out there that believe they have created something revolutionary by building their own social search (i.e. aggregating content from various other searches).  Kosmix is a pretty good example of such a search engine.  But this is the first time I’ve seen someone build social search around Google through the use of a Firefox plugin.  Above is screenshot of the plugin being used.

OneRiot connects Google search results with WebMynd History, Delicious, Fluther, CNN, Google Books, TechCrunch, Dawdle Games, LinkedIn, Scribd, Reddit, Economist, Digg, Youlicit, Y! Shopping, Hacker News, Factiva, BackType, Twitter, YouTube, Wikipedia, Flickr, Amazon Products, and OneRiot Pulse.

WebMynd can also act as a “DVR for the web” by recording your activity and search browsing history.  To download the OneRiot Firefox Plugin, visit the download page here: http://www.webmynd.com/html/oneriot.html.
