9. A discrimination method executed by an information processing device, comprising:
storing information on a type of each column included in a ledger sheet for respective styles of a ledger sheet;
acquiring, using optical character recognition, a processing target ledger sheet;
specifying one or a plurality of items names corresponding to each item value in the processing target ledger sheet;
deriving a relationship between item names as conditions to be satisfied by an item name in a style of the ledger sheet;
storing the derived relationship as column type discrimination information;
comparing a content of each column of the processing target ledger sheet to the stored information on the type of each column and the column type discrimination information;
determining whether an item name in the processing target ledger sheet satisfies a relationship between items names described in the column type discrimination information;
in response to determining the item name in the processing target ledger sheet satisfies the relationship between the item names described in the column type discrimination information, specifying style candidates of the processing target ledger sheet based on the item name in the processing target ledger sheet satisfying the relationship.
