Abstract
A recognition dictionary system includes a variant term accumulation unit, a variant frequency analysis unit, and a recognition dictionary update unit. The variant term accumulation unit is configured to accumulate and store a first variant term that has a meaning equivalent to a base term stored in a recognition dictionary and has first character string information that is different from character string information of the base term. The variant frequency analysis unit is configured to analyze an occurrence frequency of the first variant term accumulated and stored in the variant term accumulation unit and to determine the first variant term as a principal variant term when the occurrence frequency is higher than a first prescribed value. The recognition dictionary update unit is configured to update the recognition dictionary to register the principal variant term in the recognition dictionary as being associated with the base term.
