Example of coding a physical activity. A list of MET codes was matched with input and sorted based on similarity scores, from which the proper code can be selected to recode the input. If none of the candidate codes is suitable, users can either search for codes manually or decide to use ‘Unknown code’. If the button ‘Code data’ is clicked, the input is recoded only with the selected code. If the button ‘Code and add’ is clicked, the input is recoded and the input gets added to the code as a new synonym. The example is a typo of the Dutch word for ‘swimming’. zwemmen = swimming, zwemmen 2x = twice a week, soms zwemmen = occasional swimming, gym-zwemmen = water gym.
