Abstract
A general, practical method for handling sparse data that avoids held-out data and iterative rccstimation is derived from first principles. It has been tested on a part-of-speech tagging task and out- performed (deleted) interpolation with context-independent weights, even when the latter used a globally optimal parameter setting determined a posterJori.
