A computer implemented method for determining candidate data sets for labelling comprises the following steps carried out by computer hardware components: determining a plurality of sensor data sets; determining a respective signature for each of the plurality of sensor data sets; determining, based on the signature of the respective sensor data set, for each of the plurality of sensor data sets whether the respective sensor data set is a candidate data set for labelling; and providing the sensor data set to a labeling instance for labelling if the sensor data set is a candidate data set for labelling.
