kairos_sentiment

Sentiment analyzer for streaming twitter into KairosDB (with Cassandra) using Alchemy API

The Basics

Stream twitter firehose, choosing to filter OR sample by both user and term. Stuff it into KairosDB (backed by your choice of RAM, Cassandra, H2, HBase). Animate real-time graph using Dataframes (from pandas) --- NOT COMPLETE.

Some more in-depth

I originally started looking through TWEEPY and TWYTHON. I chose tweepy simply because it worked really quick and this was all started as a hack, not a serious project. The code is still there for both, but I would recommend using tweepy as I did.

I really should make a configuration file that contains all the keys, secrets, etc... that you'll require to run this and allow it to just be included where it needs to be. That's very easy to do, but I'm being lazy about it.

I used several animated matplotlib examples and hacked away at them. I finally settled and stuck some code (of my own) into pandas.py, although it's really not a subplots animation at all. It gives you ONE static graph when you call it.

This was overall more about messing around with matplotlib (since it had been a while), doing some animations with it and learning about pandas (since I really like R).

TO-DO

Figure out how to animate the pandas dataframes that get retunred. I messed around with it for a few hours, couldn't quite figure it out, so I left it, since the KairosDB GUI provides graphing for what I wanted anyway. I urge someone to educate me about how to do that if they know (couldn't find an answer).

I would assume it has something to do with manipulating different Axes subplots, but I didn't really look into it.
