We used two wonderful pieces of software to analyze our communities:
LibSVM is a free SVM toolkit that includes scripts for people who
know nothing about SVMs or classification. It allows for probabilistic classification, one-class classification, and a selection of kernels.
WEKA is a toolkit for performing general data mining tasks using machine learning methods.
It contains methods for clustering, classifying, and feature selection. Its feature selection tools in particular were very helpful to us.
