Text analytics with Python
Preview of hands-on experience using Python and Python Libraries to analyze sample tweets Goal is not to teach programming, but to illustrate in a hands-on how these processes work Understand where and how they may be useful Potential use cases Roughly what is involved in analyzing

On to text… Can use similar approach to analyze text, where your expertise identifies the type of categorization OR one where you let the computer do more of the exploring—’unsupervised machine learning’ Haven’t predefined what is right—doing ‘unsupervised learning’ to see what groupings are But we still involve human judgment, as you will see Example analysis of tweets re Haiti and Cholera
