Information processing device, information processing method, program, and recording medium

An information processing method comprising the steps of:

• referring to a table in which a characteristic of each piece of first information is expressed as distribution of model parameters in a plurality of semantic classes, in units of pieces of the first information;
• obtaining second information to be searched for;
• calculating similarities between the second information and the respective pieces of the first information;
• and
• reading the pieces of the first information from the table in descending order of the similarity.

A computer-readable program comprising the steps of:

• referring to a table in which a characteristic of each piece of first information is expressed as distribution of model parameters in a plurality of semantic classes, in units of pieces of the first information;
• obtaining second information to be searched for;
• calculating similarities between the second information and the respective pieces of the first information;
• and
• reading the pieces of the first information from the table in descending order of the similarity.
