Classification: CPC G | IPC G

Claim 13:
14. An information processing method executed in an information processing device, comprising:
allowing a notation feature amount extraction unit to extract a notation feature amount of a character string;
allowing a part-of-speech feature amount extraction unit to extract a part-of-speech feature amount of the character string; and
allowing an occurrence cost estimation unit to receive the notation feature amount and the part-of-speech feature amount of the character string and calculate an occurrence cost of the character string by applying an occurrence cost regression model, wherein
the occurrence cost calculated by the occurrence cost estimation unit is data used in a morphological analysis process, and
the occurrence cost regression model applied by the occurrence cost estimation unit is a learning model that estimates the occurrence cost from the notation feature amount and the part-of-speech feature amount of the character string, generated by a learning process using registration data of an existing morphological analysis dictionary as teacher data.
