This dataset contains data used to assess a method designed to implement Food Consumption DataBase (FCDB) enrichment task and associated results for a given use case. This use case consists in finding in USDA values associated with nutrients vitamin C, vitamin B12 and iron when they are not known in Ciqual for a given food. This data set contains three files: (1) Automatic alignments of Ciqual foods on FoodOn foods, (2) Automatic alignments of USDA foods on FoodOn foods, (3) the list of 99 Ciqual food products for which at least one of the values associated with the 3 nutrients is not known in Ciqual and at least one similar term can be found in USDA, (4) the subset of 75 alignments Ciqual->USDA found using FoodOn as pivot ontology.
