Abstract
Provided is a method of recognizing a business card by a terminal through federated learning, including receiving an image of the business card; extracting a feature value from the image including text related to a field of an address book set in the terminal; inputting the feature value into a first common prediction model and determining first text information from an output of the first common prediction model; analyzing a pattern of the first text information and inputting the first text information into the field; caching the first text information and second text information received for error correction of the first text information from a user; and training the first common prediction model using the image, the first text information, and the second text information, whereby each terminal may train and share the first common prediction model.
