Abstract
In many important document classification tasks, documents may each be associated with multiple class labels. This paper describes a Bayesian classification approach in which the multiple classes that comprise a document are represented by a mixture model. While the labeled training data indicates which classes were responsible for generating a document, it does not indicate which class was responsible for generating each word. Thus we use EM to fill in this missing value, learning both the distribution over mixture weights and the word distribution in each class's mixture component. We describe the benefits of this model and present preliminary results with the Reuters-21578 data set.
