Powerset gives wings to Wikipedia
I have tested Powerset's first product released two weeks ago. A new idea to reinvents the search and discovery experience for 3 million pages of Wikipedia articles, giving users a better way to digest and navigate content quickly, trying to understand natural language searches and competing with keyword matching engines that dominate search today. 
Powerset differs from Google and other search engines in that it linguistically parses sentences, finding subjects, verbs, objects, synonyms, and other elements, using technology licensed from Xerox PARC. It extracts and indexes concepts, relationships and meanings, rather than keywords.
Instead of being limited to keywords, Powerset allows users to enter phrases, questions or keywords. It works better in English language than Portuguese [or, in this last case, does not work yet]. To prove that, I have done simple tests, "asking" to Poweset and Google two phrases: "First man on the moon", "Quem descobriu o Brasil" and two keywords: "Carmen Miranda".
Regarding the phrase "First man on the moon", the both search engines have resulted good links (see images bellow).
Powerset "understood" some information related with the second phrase, "Quem descobriu o Brasil" (in portuguese) getting result from a Wikipedia page content about Carnival (???), and Google gave me a lot of results to be "explored"...
Finally, when I have asked these search engines only two keywords, "Carmen Miranda", I have gotten a good answer from Google
and a excellent answer from Poweset - all information related with the "artist", in a detailed and compiled way, easy to be understood.
