Metaweb

from Wikipedia, the free encyclopedia

Metaweb Technologies, Inc. was a US company based in San Francisco , which developed the open content database Freebase . The company was developed by Danny Hillis and Robert Cook as a by-product of Applied Minds in July 2005 and operated in camera until 2007. Google acquired Metaweb in July 2010.

On March 14, 2006, Metaweb received $ 15 million in core funding. Investors included Benchmark Capital , Millennium Technology Ventures and Omidyar Network . Kevin Harvey of Benchmark Capital is a member of the Metaweb Board of Directors. On January 15, 2008, Metaweb announced a $ 42.5 million capitalization, led by Goldman Sachs and Benchmark Capital.

On July 16, 2010, Google acquired Metaweb in exchange for an undisclosed amount.

At the end of 2014, Google announced that it would close its own fact database Freebase in 2015 in favor of the Wikidata project. In order to be able to transfer data to Wikidata more easily, an import tool was provided. By mid-2019, however, of around 10 million data records, only around 528,000 or less than five percent had been transferred to Wikidata.
