I am interested in excluding terms that are too broad to be biologically meaningful. Examples include anatomical entity, organ part, reproductive structure, and potentially even digestive system part.

I saw that GO has a do not annotate termset, defined as "the set of high level terms that are useful for grouping, but should have no direct annotations". Is there anything like this for Uberon? If not is there an easy methodology to accomplish the task?

Finally, are there any slim subsets that remove redundant nodes and achieve broad coverage for a given specificity level?
