NLP Personality Analysis [improved audio] 

[improved audio version] My talk on NLP and Personality Analysis at the DFW Data Science Meetup on 1/8/18:
Your writing reveals more about you than you think. Characteristics such as intelligence, political orientation, emotional stability, creativity, and job performance can reliably be predicted from even small amounts of text - sometimes even just from punctuation or pronouns. Natural Language Processing (NLP) uses statistical techniques to extract the underlying structural concepts from normal text. One of the most powerful uses of these techniques is to extract the personality characteristics of an author directly from their word choice. This talk will introduce some NLP techniques, show APIs (including IBM Watson) that allow us to extract personality dimensions, discuss the 5-factor (“Big 5”) Personality Model, and illuminate the predictive power that results. Finally, we will look at ways business are beginning to use this analysis and new possibilities - both positive and negative - now opening up due to availability of NLP personality mapping tools.
