Are apparent typos like this ever recognized and pruned?
Just the fact that talbe has only one connection to another node in the data would seem to suggest something is wrong.
In particular, it has an "is made of" relationship to {tree} which has many interconnections. Can anything be made of something ubiquitous and yet have no other connections? I suppose that is possible as new data gets added, but over time it seems it should become suspect.
Maybe some other algorithm?
