Smarter computations with SenseAxis

[DavidLeoni]

With SenseAxis can can store information that two senses or two synsets are aligned (that is, ase supposed to mean the same thing), but then Diversicon never actively uses this information, neither for reading (i.e. to avoid duplicates) nor when writing (i.e. to computer transitive closure).

Of course exploiting SenseAxis is a huge topic, for now I keep here the issue for future reference.
