Here is some experimental python3 code to download raw ICEWS files, clean them in line with this, and then, possibly, de-deduplicate and aggregate event counts.
Code is still experimental, and might be buggy. It needs a lot of commenting right now. You should probably spot check any results.
There's a blog post coming, at some point.
/text_to_CAMEO-master contains the original code from Phil Schrodt.
