MS bought Powerset in order to bring Bing to market (just like they bought QDOS to sell to IBM as MSDOS).<p>PowerSet uses:<p>Natural language parser from Xerox Parc <a href="http://news.cnet.com/8301-13953_3-9940887-80.html" rel="nofollow">http://news.cnet.com/8301-13953_3-9940887-80.html</a><p>Apache <a href="http://mail-archives.apache.org/mod_mbox/hadoop-core-user/200808.mbox/%3CC4BDF07E.5195%25michael@powerset.com%3E" rel="nofollow">http://mail-archives.apache.org/mod_mbox/hadoop-core-user/20...</a><p>Puppet server farm admin tools <a href="http://reductivelabs.com/trac/puppet/wiki/WhosUsingPuppet" rel="nofollow">http://reductivelabs.com/trac/puppet/wiki/WhosUsingPuppet</a><p>Dell servers running Linux <a href="http://lists.us.dell.com/pipermail/linux-poweredge/2007-September/032788.html" rel="nofollow">http://lists.us.dell.com/pipermail/linux-poweredge/2007-Sept...</a><p>Wikipedia entry (as indexed by PowerSet) : <a href="http://www.powerset.com/explore/semhtml/Powerset_(company)?query=what+technologies+does+powerset+use" rel="nofollow">http://www.powerset.com/explore/semhtml/Powerset_(company)?q...</a><p>I'm sure there are more smoking guns out there.
