Powerset

Last summer I had the chance to visit a pretty cool company called Powerset through a series of free lunches at various companies in the Valley, titled "Lunch 2.0". I started reading their blog which chronicles some of the issues which they are tackling and some oddities about language, which struck me as interesting. Now they've come up with something for their sematics-based search function called "Factz", which links the search to various related Wikipedia articles and shows you where the word came from in the sentence. For example, a search on epigenetics, which I'll be starting some research on soon, links to "Factz" under a subtopic of "factors". Impressively enough, clicking on that actually mentions exactly what I'll be researching - epigenetic phenomenon and their relation to the causes of senescence.

You can also search questions, which seems to be the strong suit of Powerset's search tool over most other mainstream ones. For example, a search of "What did Dwight Howard win" links to Factz about the Slam Dunk contest and the 2008 All-Star Game.

Check it out it's pretty cool!
