How we can leverage the data

Perform checks on products that are already complete

  • Check how similar ingredients lists are to what is detected
    • Calculate percentage of ingredients similarity
      • List of parsed in ingredients list
      • Ingredients found in the JSON (from the list of ingredients)
  • Check for ingredients not found in the current ingredients list (if not empty)
    • Needs ingredients taxonomisation to avoid false positives
  • Check if brands are suggested that are not here (eg Umbrella brands)
    • Taxonomize brands
    • Propose candidates
  • Check nutrition values on new images
    • Marcel Salathé seems to be working on a machine learning solution to extract nutrition values from raw images
  • Look for new languages
    • Generate a list of languages in each image/product
      • Use language detection libs to detect all languages
      • Use language value in JSON
    • Check if the product has images and values for all of them
      • values that change are (front/ingredients/nutrition images) & (front/ingredients text)
    • Make a page with a list of products with new languages to add

Suggest values for incomplete products

  • Categories candidates, based on extracted text
  • Brands candidates based on:
    • the Brand JSON field

Expand Open Food Facts coverage by adding additional information in new fields

  • Description
    • some products are very talkative, non-essential marketing information (eg on wines)
    • it can be a first step before we add the other fields
  • Cooking recommandation
  • Storage recommandation
  • Postal address of the producer
  • Postal address of the distributor
  • Email Address of the producer
  • Email Address of the distributor
  • Phone number of the producer
  • Phone number of the distributor
