Ingredients Analysis Quality Evaluation - March 2020 - May 2020

In early March 2020, we made an evaluation of the quality of Ingredients Extraction and Analysis so that we could measure the improvements made as part of the Ingredients analysis and search features extraction task of the Project:Personalized_Search.

The metrics have also been recorded in mid May 2020 in order to measure the impact of the improvements we made.

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 (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)

In the table below,

• the first column of numbers corresponds to the number of unique ingredients accross 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.

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.

Evolution of the metrics between early March 2020 and mid May 2020

Comparison of key metrics

The comparison table contains the metrics for all products of a country.

Metrics:

• Ingredients parsing and recognition: % of known ingredients for all ingredients occurences.
• Ingredients analysis: known vegetarian status
  • = 1 - "Vegetarian status unknown" / ("Vegetarian status unknown" + "Vegetarian" + "Non vegetarian" + "Maybe vegetarian")

Country	% known ingredients March 2020	% known ingredients May 2020	% known vegetarian status March 2020	% known vegetarian status May 2020
UK	79.75%	80.82%	27.20%	45.94%

Observations

Significant progress has been made on all tested countries.

For ingredients parsing and recognition, it becomes harder and harder to get big increases in the % of known ingredients. It is expected as we have focused first on the improvements that had the biggest impact. But even a "small" increase from 83.40% to 85.55% for known ingredients in France corresponds to a drop of the unknown ingredients from 16.60% to 14.65% which is a 11.7% relative drop.

It is very interesting to see that the improvements in ingredients parsing and recognition translate in much more significant ingredients analysis (knowing the vegetarian status of a product) improvements. All countries had a 5% to 25% absolute increase of products with known vegetarian status.
