Abstract
A method of semi-supervised synonym inference for a call handling application, such as automated directory assistance or call routing, is described. In one embodiment the method comprises examining a database of caller interaction results from a directory assistance system that includes an automated directory assistance engine, detecting a specified characteristic in the caller interaction results, and using the detected characteristic to automatically train a destination map, where the destination map is for use by the automated directory assistance engine in automatically mapping human speech to a destination. The detecting of the specified characteristic in the caller interaction results may include a statistical analysis of the caller interaction results for each of one or more speech recognition strings.
