Hernan Galperin from DIRSI had organized a session entitled Data for development: the good, the bad and the ugly. Martin Hilbert was originally featured as the star speaker who would tell the audience about the wonders of big data. Well, he did not turn up. So it was left to LIRNEasia, where we actually get our hands dirty analyzing big data of relevance to our primary clients, the poor of the developing world, to talk about big data. The slides are here.
