At first I started reading this as though it were a paper, and was surprised to realise that it doesn't reference Microsoft Probase[1], which is probably the leading concept-relation knowledge base around. Nor (as noted below) Cyc, WordNet or NELL.
Actually, it's a somewhat interesting tutorial on how to implement graphs like these in Python.
