Abstract
An electronic device automatically classifies documents based upon textual content. Documents may be classified into document categories. Statistical characteristics are gathered for each document category and these statistical characteristics are used as a frame of reference in determining how to classify the document. The document categories may be intersecting or non-intersecting. A neutral category is used to represent documents that do not fit into many of the other specified categories. The statistical characteristics for an input document are compared with those for the document category and for the neutral category in making a determination on how to categorize the document. This approach is extensible, generalizable and efficient.
