I have some expertise with Apache Hadoop and was wondering if I could use it in processing the datasets which are made available here. I am mainly looking at Addresses, business license and crime reports data sets. I plan to cluster the crime reports and recommend areas which are less susceptible to crime. I am running short of ideas. If anybody can give me some more interesting ideas involving other data sets, I will be able to implement them using Hadoop. My main goal here is to use Hadoop on the real world data sets and develop something useful for the common man.
