The page details the Ingredients List Cutting procedure and implementation.

Procedure

We talked about ingredients list extraction on last Data Quality meeting (by the way, DQ meetings are every first Tuesday of the month at 18:00 CEST, everyone can join). We would like to improve the extraction. Everybody can help there. When you edit a product, if you extract text from the picture and you see some parts of the text that you have to remove by yourself. "store in a cold place", "after opening blablabla", for examples. This part can be done automatically by Open Food Facts when you click on the button to extract. We just need to list all possible occurences. So, we can start with the 4 followings: %phrases_before_ingredients_list all text that are before the ingredients list, that need to be removed. %phrases_after_ingredients_list all text that are after the ingredients list, that need to be removed ("store in a cold place", for example). %may_contain_regexps the traces should be extracted, but when you click on "Details of the analysis of the ingredients" they should not appear as ingredient (except if one trace-ingredient is not recognized, see previous discussion with Moon Rabbit https://openfoodfacts.slack.com/archives/C06A7LENM/p1690126832563859). %ignore_regexps that would be text that is after ingredient list and should be ignored but you keep it because you have allergens list after Currently all possible occurences are not yet referenced for all languages. Hence, if you if you see some text that you have to remove when you extract the text, just write in this thread: the text if it is %phrases_after_ingredients_list or %may_contain_regexps or something else the link to the product

Implementation

Examples

Some example to illustrate which words refer to what part of the raw ingredients extraction.

Thyme cashews

So if we take this product as example, go to edit, ingredient, extract text:

  • text start after "Ingredients:" -> nothing to add in %phrases_before_ingredients_list
  • text does not stop! It continues with French ingredients list. We would like to add "Packed in a modified atmosphere" in %phrases_after_ingredients_list to ignore "Packed in a modified atmosphere" and everything after
  • %may_contain_regexps, it looks good. "May also contain" is recognized and when you click on "Details of the analysis of the ingredients" in the product page https://world.openfoodfacts.org/product/5281026016014, the text "May also contain soy, peanuts, sesame seeds, milk" is not there [One allergen (milk products) is unknown in the taxonomy, it appears as unknown ingredients. But this is another topic].
  • %ignore_regexps, "For allergens see ingredients in bold." in the ingredients list does not appear in "Details of the analysis of the ingredients". This mean that "For allergens see ingredients in bold." is already known as ignore_regexps. All good there as well.
  • Packed in a modified atmosphere.
