Calculating machine, prediction method, and prediction program

A prediction method using a calculating machine including a processor and a memory,

• wherein the calculating machine stores intermediate data generated for each of a plurality of products or services based on social media data including statements on the products or services for a predetermined period of time in the memory,
• the intermediate data includes at least a frequency of statements on each of the products or services for the predetermined period of time,
• the products or services include a first product or service that is not displayed for provision to a consumer at a present time, and at least a second product or service that has been displayed for provision at the present time,
• the calculating machine stores sales amount data indicating a sales amount of the second product or service in the memory,
• the method comprising:
• calculation of a correlation degree in which a social media correlation degree indicating a correlation between the intermediate data about the first product or service and the intermediate data about the second product or service is calculated by the processor;
• and
• prediction of a demand in which a sales amount of the first product or service is predicted by the processor based on the calculated social media correlation degree and the sales amount data about the second product or service.

A prediction program for causing a calculating machine including a processor and a memory to perform processes,

• wherein the calculating machine stores intermediate data generated for each of a plurality of products or services based on social media data including statements on the products or services for a predetermined period of time in the memory,
• the intermediate data includes at least a frequency of statements on each of the products or services for the predetermined period of time,
• the products or services include a first product or service that is not displayed for provision to a consumer at a present time, and at least a second product or service that has been displayed for provision at the present time,
• the calculating machine stores sales amount data indicating a sales amount of the second product or service in the memory, and
• the prediction program causing the calculating machine to perform the processes comprising:
• calculation of a correlation degree in which a social media correlation degree indicating a correlation between the intermediate data about the first product or service and the intermediate data about the second product or service are calculated;
• and
• prediction of a demand in which a sales amount of the first product or service is predicted based on the calculated social media correlation degree and the sales amount data about the second product or service.
