last time I looked at OpenCyc's knowledge base, the information encoded was all strangely specific academic stuff - like very fine classifications and relationships between species of tapeworms and of fungus. There was very little daily-life common-sense knowledge, even though that's often the hook in interviews and articles about Cyc's purpose. I'm not sure why that's true - maybe it's hard to decide what the 'facts' are about normal human life, but the more academic something is, the more there's a consensus, rationalized 'reality'

Employee of Cycorp here. A few thoughts:

- At least right now, we have a good amount of common-sense information about the world (I don't know when "last time" was for you).

- That said, we have a lot of highly specialized knowledge in various domains, so if you took a random sample of the knowledge base (KB) it may not be as common-sense-centric as you'd hope. But the KB is also incredibly large, so that doesn't mean we don't have much common-sense, just that we have even more other stuff.

- Often for contracts we get paid to construct lots of domain-specific knowledge, even if the project also uses the more general knowledge, so this biases the distribution some.

- Information that's already well-taxonomized is low-hanging fruit for this kind of system; its representation doesn't take nearly as much extra thought and consideration, so it's a faster process, which also biases the distribution some.

What are some interesting examples of common-sense that has been formalized and encoded?
