... language model for speech recognition was measured both by parsing accuracy (parsing strings with annotated reference parses), and by WER. WER is measured by parsing word lattices and comparing the sentence yield ... refer- ence transcription (using NIST SCLITE for align- ment and error calculation). 5 We assume the pars- ing performance achieved by parsing strings carries...

... lexicon contains, for each word, a list of possible lexical categories, subcategorization information, and in a few cases, information on compound words. For example, the entry for round states ... the surface string (i.e., for transcripts, the orthographic string) before any syntactic proct i,~. For example, in (7), the underlined strings are expunged before parsing begins...
