This paper presents the results of using statistical analysis and automatic text categorization to identify an author’s age group based on the author's online chat posts. A Naive Bayesian Classifier and Support Vector Machine (SVM) model were used. The SVM model experiments generated an f-score measurement of 0.996 on test data distinguishing teens from adults. We also introduce an alternative method for generating “stop words” that chooses n-grams based on their relative distribution across the classes.
