Abstract: An extraction system includes an output unit, an acquisition unit, and an update unit. The output unit outputs a feature amount used for similarity determination by an extraction model that extracts a product similar to a target product, a set value of an importance level of the feature amount, and a change field for changing the set value of the importance level of the feature amount. The acquisition unit acquires a change value for changing the set value of the importance level of the feature amount input in the change field of the output screen. The update unit updates the set value of the importance level of the feature amount in the extraction model based on the change value. The extraction system can be used, for example, to support decision making.
