I don't believe that book is being used as a literal blueprint, but rather more as a general inspiration. (I could be mistaken) I've mostly stayed away from reasoning, but it is sort-of coming up as almost my #1 priority, so I plan to get active in it very soon now, once I clear my plate of assorted half-finished projects. > > Is the work on this set of ideas dead in the water or is this actively > pursued and lastly, may we help with it?

The specific issue there is that the space-time server can get 3D+time coordinates from external sources (video cameras, piped through tensorflow or whateverr whizzy software does image stuff these days, which extracts 3D positions and extents, maybe some object-type labels, and pumps them, 30 frames a second, into ROS nodes (ROS==robot operating system) ROS has a fairly rich infrastructure for this kind of stuff (self-driving cars, yada yada), so its good for sensing, tracking, SLAMming, etc. tasks. The opencog spaceserver can cooperate with ROS to get those 3D coords. That part is done. The very next step is to implement basic "common-sense" prepositions: above, below, behind, next-to, near, far, left-of, right-of, closer, farther...(it is a finite list: there are a rigidly fixed number of prepositions in the English language). The goal of having prepositions is to allow a natural language chatbot to talk about what is sees. (or hears...) This is a sideways to "reasoning" -- its more about knowing, and chatting about what you know. -- Linas > > > Johannes > > > On Saturday, February 2, 2019 at 3:09:54 PM UTC, linas wrote: >> >> >> >> On Sat, Feb 2, 2019 at 4:03 AM 'Nil Geisweiller' via opencog < >> [email protected]> wrote: >> >>> >>> I'm longing to go back to spatio-temporal reasoning but I'm involved >>> with other matters. >>> >>> Linas, Amen?
