NodeXL: Network Overview, Discovery and Exploration for Excel
It is a bit disheartening to know that the predictive analytics/big data world is moving ahead so quickly just as I am trying to learn how to harness it. But it is also nice to find the many open source data analysis tools – user friendly types – becoming commoditized on the Web of Things. Two came to my attention today: First, a text analysis tool by the data folks at Stanford at http://www.etcml.com/ that among other things can analyze your (or anyone’s) Tweeter feed for positive or negative “feeling.” Second is a neat network analysis/mapping add-in for Excel http://nodexl.codeplex.com/ that I’m going to use to map some learning communities I’m interested in. You should check out their look at politics on Twitter on their website.
I respectfully suggest you “play” with them. šŸ™‚
