Cleaned it up. Likely to be the final version unless I figure out image processing. That may be an entirely different presentation though.
Presentation given for BarcampNOLA7.
Touched on a variety of topics like natural language processing, sentiment analysis, and ethics. Chose the context of Twitter since I'm more familiar with text processing than image processing. Twitter has some unique problems that make it not straightforward to take the data that is covered here.
Overall, the presentation went longer than expected (The time frame was 15-30 min). Didn't have much time for discussion, although one spawned about the inaccuracy of sentiment analysis. No questions, though I blame the length of the presentation. I also was expecting the room to be mostly computer programmers, but there were some business people, sales, and marketing.
Next time I present, I would give myself more time (45 seems more reasonable) to elaborate on important topics I had to skim through (ethics, programming algorithms, consumer psychology and irrational behavior).
