There are three ways to do this: 1) use moses 2) use the pattern miner 3) use the language-learning subsystem. 4) the neural net subsystem, Ralf is working on that, its a kind-of generalization of the earlier "destin", and using tensorflow under the covers. So far, it's been used to create facial expressions (for use in humanoid robots) I'm currently am working on language learning and have vague plans to port it over to the pattern miner, someday. I haven't looked at the pattern miner yet, I'm guessing that it remains at a rather primitive, low level, for now. Basically, moses is "mature" the other three are not, they're in very active development. --linas On Friday, April 28, 2017 at 9:47:45 AM UTC+5, Daniel Gross wrote: > > Hi Linas, > > I guess i should further ask: > > What determines the expressiveness of OpenCogs representation, the one > that is bult-into its inference. > > thank you, > > Daniel > > On Thursday, 27 April 2017 05:27:45 UTC+3, linas wrote: >> >> >> >> On Wed, Apr 26, 2017 at 2:06 PM, Nageen Naeem <[email protected]> wrote: >> >>> how I can differentiate knowledge representation in OpenCog and >>> traditional knowledge representation techniques. >>> >> >> Opencog is really pretty traditional in its representation form.
