  1   CS 388: Natural Language Processing: N-Gram Language Models Raymond J. Mooney University of Texas at Austin  Language Models ã Formal grammars (e.g. regular, context free) give a hard “binary” model of the legal sentences in a language. ã For NLP, a probabilistic   model of a language that gives a probability that a string is a member of a language is more useful. ã To specify a correct probability distribution, the probability of all sentences in a language must sum to 1.  Uses of Language Models ã Speech recognition  – “I ate a cherry” is a more likely sentence than “Eye eight uh Jerry” ã OCR & Handwriting recognition  –  More probable sentences are more likely correct readings. ã Machine translation  –  More likely sentences are probably better translations. ã Generation  –  More likely sentences are probably better NL generations. ã Context sensitive spelling correction  – “Their are problems wit this sentence.”    Completion Prediction ã A language model also supports predicting the completion of a sentence.  –  Please turn off your cell _____  –  Your program does not ______ ã  Predictive text input   systems can guess what you are typing and give choices on how to complete it.
