And one more thing, then: https://github.com/watson-intu/self/tree/develop/src/blackboard
is a "blackboard" -- see https://en.wikipedia.org/wiki/Tuple_space https://en.wikipedia.org/wiki/Blackboard_(design_pattern) https://en.wikipedia.org/wiki/Blackboard_system Note how everything in the black-board is hard-coded: person, health, entity, image, gesture, etc. In opencog, we have a blackboard too, its called "the atomspace". It can store arbitrary data in a persistent fashion. http://wiki.opencog.org/w/AtomSpace The atomspace stores very low-level objects, that roughly resemble "assembly code": the kind of stuff a compiler might act on. There's actually a lot of compiler-like stuff in the atomspace. There's a reason for that: we want high-level algorithms to be able to examine and alter patterns, and to learn brand-new patterns. Thus, we do NOT want to fix the representation of "person, health, entity, image, gesture,etc" into a frozen, unchangeable C++ object that only human programmers know how to modify. We want opencog systems to learn, on their own, what people, health and gestures might be, and alter these definitions over time. (De facto, we do hard-code a lot of stuff like that, but the long-term goal/design is not to do that) Also the atomspace can be: -- saved to disk -- can be searched and queried -- can hold rules, and comes with a rule engine The watson-intu/self system can't do any of these things, as far as I can tell. Let me know if I'm wrong: I love to rip off ideas: "imitation is the sincerest form of flattery" if there's something worth imitating, let me know. I am humble enough to just-plain "ape" if I can't imitate. --linas On Sat, Jul 15, 2017 at 3:14 PM, Linas Vepstas <[email protected]> wrote: > Maybe a year ago, I got a brief pitch of some Watson robot code, to which > my reaction was "OMG they are reinventing ROS from scratch, badly".
