CORPUS PROCESSOR FOR GENERATING STATISTICAL LANGUAGE MODEL, AND METHOD AND PROGRAM THEREOF

摘要

PPROBLEM TO BE SOLVED: To prevent secret information included in a database or existent corpus from leaking out. PSOLUTION: A text analysis part 102 outputs a morpheme analytic result of a text. A storage part 104 stores a mask rule in which information for masking a person's name is described. A secret information mask part 103 masks the morpheme analytic result according to the mask rule. Consequently, no secret information is included in the morpheme analytic result from the secret information mask part 103. A corpus totaling part 105 totals morpheme analytic results to generate a corpus excluding the secret information. According to the corpus, a statistical language model is generated. Accordingly, no secret information leaks out in speech recognition processing using the statistical language model. PCOPYRIGHT: (C)2003,JPO
