Or any open source project which utilize collective intelligence extensively?.
回答1:
There's a new book out from Manning, "Collective Intelligence in Action". There are also code samples available written in Java. I also recommend the Toby Segaran book. Coming from a Java background I was able to follow the Python code without a problem.
回答2:
Take a look at the book Collective Intelligence by Toby Segaran. It covers lots of topics, such as how Amazon generates recommendations etc etc. There's lots of source code in the book written in Python, which should be easy to port to Java/.Net
回答3:
look up weka (java) and the Datamining book by Franke and Witten
