Computer system and presentation method of information

A presentation method of information to be performed by a computer system,

• the computer system including at least one computer and being accessible to a first database storing a plurality of pieces of learning data to generate a prediction model for predicting an event in a subject,
• each of the plurality of pieces of learning data including input data and teacher data, the input data including a plurality of feature values that are values of items representing characteristics of the subject, and
• the presentation method of information including:
• a step of performing, by the at least one computer, first learning to set an extraction criterion for extracting learning data including the input data similar to prediction target data which includes the plurality of feature values in a case of being input the prediction target data;
• a step of extracting, by the at least one computer, at least one on a piece of learning data from the first database based on the extraction criterion and generating a dataset including the extracted at least one of the piece of learning data;
• a step of performing, by the at least one computer, second learning to generate a prediction model using the dataset;
• a step of generating, by the at least one computer, a decision logic showing a prediction logic of the prediction model based on the prediction model;
• and
• a step of outputting, by the at least one computer, first information to present the decision logic.
