Where to learn about 'Collective Intelligence'?

Which are the good resources for research in Collective Intelligence ?.

I am a Software Developer,for a year now and I am basically working in Java and Flex platforms. I want to now apply for a PHD in 'Collective Intelligence', to make my application stronger I want to read thoroughly about it before applying.

I just need some good tutorials / blogs before dipping into the complexities.... Thanks!!

Indeed, Collective Intelligence is a very broad term. You might have to come down and pick an ideal one of choice. I have done some bit in Semantic Web which is a collective intelligence science. There are tonnes of materials available online. These are some of the informations which might help you out...
