topic-pov

Code for fitting a topic and point of view (POV) model of collective intelligence processes, using parallel Gibbs sampling. Also includes synthetic data generation for testing and evaluation.

To compile and run:

make
bash test_synth.sh 50 500

You will need the GNU Scientific Library (GSL) headers installed to compile everything. See comments in test_synth.sh for a high-level overview of the inference process.
