Text Mining Short Course - in San Francisco

Intro to Natural Language Text Mining - Short Course

This class will cover machine learning applied to natural language text documents.  Applications include: text-based search, predicting page reads based on text content, sentiment analysis and automated page and email construction based on user history.  We will cover the use of statistical algorithms for accomplishing machine learning tasks on texts.   

The course starts with some introduction to the subject matter, comparison of statistical techniques to semantic approaches, definition of problems in text mining, and simple text manipulations.  We'll go through some basics of the R-language so you can follow the code examples presented.  We'll cover various algorithms for dealing with standard text mining problems, such as indexing, automatic classification (e.g. spam filtering) topic modeling, classification etc.

I decided to start Reno Motorcycle Riders Group because I wanted to be part of a group of people who enjoyed my passion... I was excited and nervous. Our group has grown by leaps and bounds. I never thought it would be this big.
