Abstract
A method of classifying a document includes providing a plurality of classifier engines and classifying the document using output from one or more of the classifier engines based on a comparison of one or more metrics for each classifier engine. In another embodiment, a method of classifying a document comprises providing a plurality of classifier engines and determining one or more metrics for each classifier engine. These metrics are used to determine how to use the classifier engines to classify the document, and the document is classified accordingly. A further embodiment includes a document classifier utilizing a plurality of classifier engines. In yet another embodiment, a computer-readable medium contains instructions for controlling a computer system to perform a method of using a plurality of classifier engines to classify a document.
