Recognition device, method and storage medium

A method executed by a recognition device comprising storage configured to store a first recognition model created based on a first data set comprising first recognition target data collected under a predetermined condition and first correct data to be recognized from the first recognition target data, the first data set, and tags indicative of the condition, for each first recognition model, the method comprising;

• acquiring a second data set comprising second recognition target data and second correct data to be recognized from the second recognition target data;
• executing recognition processing of the second recognition target data in the second data set by using the first recognition model stored in the storage;
• extracting a significant tag of the tags stored in the storage in association with the first recognition model used for the recognition processing, based on the recognition processing result and the second correct data in the second data set;
• and
• creating a second recognition model based on the acquired second data set and the first data set stored in the storage in association with the extracted tag.

A non-transitory computer-readable storage medium having stored thereon a computer program which is executable by a computer using storage configured to store a first recognition model created based on a first data set comprising first recognition target data collected under a predetermined condition and first correct data to be recognized from the first recognition target data, the first data set, and tags indicative of the condition for first recognition model, the computer program comprising instructions capable of causing the computer to execute functions of:

• acquiring a second data set comprising second recognition target data and second correct data to be recognized from the second recognition target data;
• executing recognition processing of the second recognition target data in the second data set by using the first recognition model stored in the storage;
• extracting a significant tag of the tags stored in the storage in association with the first recognition model used for the recognition processing, based on the recognition processing result and the second correct data in the second data set;
• and
• creating a second recognition model based on the acquired second data set and the first data set stored in the storage in association with the extracted tag.
