Model update support system

A model update support system comprising a processor,

• the processor receiving input of a plurality of data,
• the processor referring to a first model trained using a training data group, the training data group including a plurality of labeled data and including a plurality of labels respectively labeling the plurality of labeled data,
• the processor acquiring a plurality of classification certainties by using the first model, the plurality of classification certainties respectively indicating surenesses of classifications of the plurality of data,
• the processor extracting first data from the plurality of data based on the plurality of classification certainties, and extracting, from the plurality of classification certainties, a first classification certainty indicating a sureness of a classification of the first data,
• the processor calculating a plurality of similarities respectively indicating likenesses between the first data and the plurality of labeled data,
• the processor being configured to output, based on the plurality of similarities, information relating to the first model.
