Computer-readable recording medium, information processing method, and information processing device

An information processing method that causes a computer to execute a process comprising:

• inputting a video of respective possible items available in a store to a machine learning model trained to specify an item from the video, and calculating and storing scores indicating a level of reliability of the respective possible items;
• acquiring a video of a person who grasps an item to be registered in an accounting machine;
• inputting the acquired video, and calculating a first score that is highest among the scores of the respective possible items;
• acquiring, from among the scores of the respective possible items, a second score corresponding to the item that is registered in the accounting machine by the person by operating the accounting machine;
• when a difference between the first score and the second score is equal to or greater than a threshold, determining that the item grasped by the person is different from the item registered in the accounting machine;
• and
• generating an alert indicating abnormality of the item that is registered in the accounting machine.

An information processing device comprising:

• a memory;
• and
• a processor coupled to the memory and configured to:
