Abstract: One aspect of the disclosure can be embodied in a method that includes obtaining a first document from a corpus and obtaining metadata for the first document. The method also includes obtaining existing change rates for second documents selected based on the metadata, and calculating an estimated change rate for the first document based on the change rates for the second documents.
