1. An information processing device comprising:
a notation feature amount extraction unit that extracts a notation feature amount of a character string;
a part-of-speech feature amount extraction unit that extracts a part-of-speech feature amount of the character string; and
an occurrence cost estimation unit that receives the notation feature amount and the part-of-speech feature amount of the character string and calculates an occurrence cost of the character string by applying an occurrence cost regression model, wherein the occurrence cost is data used in a morphological analysis process, and
the occurrence cost regression model 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.
