Abstract
A document classifier may analyze documents for a search engine and tag the documents. A document classifier system may have several different classifiers, each with a separate algorithm for classification. Some of the data classifiers may learn or change the classification over time with a feedback loop. As those classifiers are modified, updated, replaced, or added, the documents that have already been classified by the classifier may be re-examined to update their classification. The document classifier system may maintain a database of documents with a timestamp that the document was classified that may be used to identify those documents whose classifications may be out of date.
