Ingredients Analysis Quality Evaluation - August 2023

Evaluation of the quality of Ingredients Extraction and Analysis so that we can measure the improvements.

Ingredients parsing and recognition

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 (misspellings 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 formatting (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)

In the table below,

• the first column of numbers corresponds to the number of unique ingredients across all products.
• And the second column of number corresponds to the number of occurrences of those ingredients. e.g., if a specific ingredient appears in 5 products, it is counted 5 times.
