== Ingredients parsing and recognition metrics ==
 +
 +
For each product, the ingredients list is parsed to separate each ingredient. Ingredients that we can match to our multilingual ingredients taxonomy as marked as "known", others as "unknown".
 +
 +
There are different reasons an ingredient can be marked as unknown:
 +
 +
* The input ingredient list is incorrect (mispellings etc.)
 +
* The ingredients list contains other things than ingredients and we have not been able to split it at the right place.
 +
* We have not been able to parse a particular sentence structure or formating (e.g. "a drop of delicious honey with a shower of powder sugar")
 +
* The ingredient is not yet present in our taxonomy (or not with the right synonym or in the right language)

== Ingredients analysis ==
 +
 +
For each product, once we have parsed the ingredients list to separate each ingredient and match them to our taxonomy, we can analyze if the products are vegan, vegetarian, without palm oil etc.
 +
 +
To mark a product as non-vegan etc. we only need to find one non-vegan ingredient. But to mark a product as vegan, we need to be sure that we have been able to correctly recognize all ingredients so that we can verify that all of them are vegan.
