There is great work out there that mines Wikipedia for semantic relationship (co-occurrence of topics for example, parent-child relationships, etc.). But that methodology would not provide the statistical evidence that is the building block of System. Relationships on System are statistical in nature. A predicts B, C is caused by D, E and F are highly correlated, G and H change together, etc. By organizing these (billions and billions of) statistical relationships, anyone will be able see anything that's important to them as the system it truly is, rather than the silo we often see today.
