... which re- flects the semantics of the “otherwise” formulation of smoothing (Allauzen et al., 2003). For example, the typical backoff formulation of the probability of a word w given a history h ... its use for speech and language processing tasks. We prove that the semiring allows for exact en- coding of backoff models with epsilon tran- sitions. This allows for off-line opti...
