Request routing with a backerror propagation network

A pilot project of the Center involves automatic document delivery in response to computerized Interlibrary loan requests. Each document request includes an unstructured comment field that patrons occasionally use to indicate whether or not they want the National Library of Medicine to fill that request. These comments vary widely in content, but were found to always contain the test 'NLM.' This paper describes a technique to automatically reduce the amount of operator intervention to resolve ambiguities in the intent of the patron as to whether the request should be filled or not.
