Quality Monitoring

Generic errors

• Data quality errors that can be detected;

Superfluous categories

Only the categories that belong to the parents should be present as category. Checking the categories list might help finding wrong one.

Categorisation errors

• Single ingredient check:
  • Plain pistachios should only contain the ingredient Pistachio;
• Internel opposites:
  • Plain pistachio and Pistachios(salted), Pistachios(roasted) should not be assigned simultaneously;
  • Pistachios(salted) and Pistachios(unsalted) should not be assigned simultaneously;
  • Pistachios(shelled) and Pistachios(unshelled) should not be assigned simultaneously;

• Oneside opposites(these are categories which are incompatible and which are often due to adding an ingredient as a category):
  • Mixed nuts - to detect adding all the different nuts in mixed nuts;
  • Chocolate covered pistachios - to detect chocolate covered nuts;

Sales format

Pecan nuts are sold by:

• package - pre-packed in the nuts aisles;

Issues

Quite a lot of products have issues with nutritional values. It seems due to a difference in weight used, either with or without shells.

A few other subcategories could be defined, but have few products at the moment:

• Hacked pistachios for pistachios that have been hacked into small pieces;
• Pistachio butters(100%) for pistachions that have been ground without added ingredients like sugar or oil;;
