Abstract:
We describe a supervised text classification approach based on a greedy feature selection method, which uses a support vector machine (SVM) classifier. As feature selection method we use the mutual information. This measures the quantity of information about the categories contained by the words. To train and test the algorithm we used patent documents from the US Patent Classification System. Average break-even point (BEP) for some US Classes is reported as conclusion.
