CREATING A LANGUAGE MODEL FOR A LANGUAGE PROCESSING SYSTEM

摘要

A method (20) for creating a language model from a task-independent corpus is provided. In one embodiment, a task dependent unified language model (140) is created. The unified language model (140) includes a plurality of context-free grammars (144) having non-terminals and a hybrid N-gram model (142) having at least some of the same non-terminals embedded therein.
