| + | To build the taxonomy from raw data, the follow steps need to be taken |
| + | * '''Gathering''' - the first step is gathering the ingredients from the ingredient lists. This results in a list of ''raw ingredients''. This process needs to be described @stephane does this; |
| + | * '''Assigning''' - the raw ingredients can be mapped unto the existing taxonomy, in order to find ingredients that are new and not yet part of the taxonomy (the ''new raw ingredients''); |
| + | * '''Merging''' - each new raw ingredient must be looked at and if possible merged with an ingredient in the existing taxonomy; |
| + | * '''Keying''' - if a new raw ingredient can be mapped to the taxonomy, it will probably be a new synonym of an existing entry. Ideally one should check which of the synonyms occurs the most and set that one as main ingredient name; |
