This course gives you a rare glimpse into how some of the top technology start-ups are using intelligent software like NLP (natural language processing) to understand what their customers write without having humans actually go through what's written. This course is based on a private talk given by one of the engineers who works at FourSquare. The talk covers many topics like how the engineers at FourSquare determine text sentiment, how they deal with time issues related to when certain text was written, how they detect and deal with spam, and much more. This course will take about an hour to complete. It is all video, which is Udemy's preferred course lecture type. If you have any questions about the course, send me a direct message and I will get back to you within 24 hours. This course is intended for software engineers who are interested in learning NLP, and want to know about some of the practical applications of natural language processing.
