Google Squared
This weekend, I have been spending my time for trying Google Squared. Google Squared works the same as Google Search with a simple query text box but now we can enter the query as a class of entities, e.g. "digital camera" (http://www.google.com/squared/search?q=digital+cameras&suggest=3) or "Information retrieval book" (http://www.google.com/squared/search?q=Information+Retrieval+book). Google Squared amazingly does entity extraction, classification and clustering to return properties of "digital camera" such as "name of camera", "manufacturer", "resolution", etc. The search result will be shown in spreadsheet using AJAX therefore you can add or remove columns as you want.
You may try Google Squared at http://www.google.com/squared/

Tried it, recall is too low. Fail to build meaningful stuff or build anything for a lot of queries.
This type of advanced search functionality is best applied to a specific vertical like cars/phones, to raise user awareness and skills in learning how to use it properly.
