Abstract
A probabilistic document categorizer has an associated vocabulary of words and an associated plurality of probabilistic categorizer parameters derived from a collection of documents. A new document is received. The probabilistic categorizer parameters are updated to reflect addition of the new document to the collection of documents based on vocabulary words contained in the new document, a category of the new document, and a collection size parameter indicative of an effective total number of instances of vocabulary words in the collection of documents.
