Objectives

  • Detect potential errors in order to correct them and prevent them
  • Do not take into account the products whose information is questionable in the calculations of averages

Ideas to automatically detect products that contain errors entering information

  • Sum of components of nutritional table well above 100g
  • Sum of ingredients well over 100g (detection and complicated products )
  • Confusion between "l" ( lowercase letter L ) and 1 (one) in the list of ingredients because of the OCR, which gives: nom_de_l'ingrédient l5 %
  • Sum of " that sugar / starch / etc . " than carbohydrates (and the same for fat etc.).
  • Energy over 4000 kJ
  • Height from the upper portion to the size of package
  • "CO2 Carbon Footprint" greater than 3 000g
  • Over 12 additives
  • Quantity of "sugars" greater than the amount of "carbohydrate"
  • Sum of fatty acids greater than the amount of "lipids"
  • etc.

Note

Each track (each rule) must have a unique number associated clearly: Once an accurate method of error detection is translated computer (is implemented), then this method becomes a rule. The automatically assigned number to this rule allows contributors to designate it unambiguously.
