Seems to be the week for search related innovation, after Google’s Goggle, etc. MS research announced a really interesting project called entity cube.

At the homepage it summarises current hot topics and news

And if you search for someone or an organisation it builds a dynamic page almost like a Wikipedia page about that entity

And even can show a Guanxi map to show the six degrees of separation style results
