Seems like a subset of CYC - attempting to gather causal data rather than declarative data in general.

It's a bit odd that their paper doesn't even mention CYC once.

Cyc is hardly [1] mentioned in modern work under the knowledge representation and reasoning umbrella, because most [2] of it was/is unavailable or unknown to most researchers. It's hard to build on something that's primarily marketing material.

[1] I could be wrong, but even those that mention Cyc use it only as a historical example of early work in KRR / symbolic AI. [2] OpenCyc being the small subset which is available, tho I haven't met anyone who worked with it.

Everything old is new again
