part of relations go through is_a, (a part_of some b, b subclassOf c
=> a part_of some c) and there can be negations in the GO
annotations. If you get into subproperties, some of which are
transitive and some not it gets ev
Here's my way of looking at this.
The information from which the classrelations graph was derived was
the original OWL. We'd like a world in which we can query the OWL,
with reasoner support, but we don't have that yet. We will at some

The most common way of doing inference in tri
