Today, Oath, the Verizon-owned company born of the merger between AOL and Yahoo, released the source code of a data-crunching tool called Vespa, which has long-powered search and other features across the Yahoo empire. Yahoo also uses Vespa to power related-article recommendations and ad-targeting on many Yahoo-branded sites, including Yahoo News, Yahoo Sports, Yahoo Finance, and its advertising network. Don't Laugh: Yahoo's Open Source AI Has a Secret Weapon Vespa's history traces back to the Norwegian search engine AlltheWeb, which Yahoo acquired in 2004. By making Vespa open source, Oath VP of engineering for big data Peter Cnudde says the company hopes to replicate the benefits it has reaped from supporting Hadoop, an open-source software framework for managing big data.
