Unclear Activity Types

In my perspective, Activity Types should all have informative descriptions of some activity taking place.
This is the case for many of the activities, such as **Cultivation of wheat** and **Processing of meat pigs**. These are easy to read descriptions (`rdfs:label`) of the given activity. However, not all activities have such easy to understand descriptions, for example **Wool, silk-worm cocoons**, **Meat animals nec**, **Raw milk** or **Animal products nec**. It is hard to understand what is the activity taking place here. I think this problems relates to the Bonsai classification when extracting information from Exiobase.

Start by tracing how the BONSAI classification is used when extracting activity information from Exiobase. Compare the rdfs:label values for the named clear and unclear activities, then determine what change would make every Activity Type an informative description and how that result can be verified.
