Ontology Summit 2024 Foundations and Architectures


  • 12:00-12:05 Introduction Ravi Sharma
  • 12:05-12:40 Gary Marcus No AGI (and no Trustworthy AI) without Neurosymbolic AI
  • 12:40-12:50 Discussion
  • 12:50-13:30 John Sowa Without Ontology, LLMs are clueless
    • Abstract: Large Language Models (LLMs) are a powerful technology for processing natural languages. But the results are sometimes good and sometimes disastrous. The methods are excellent for translation, useful for search, but unreliable in generating new combinations. Any results found or generated by LLMs are abductions (hypotheses) that must be tested by deduction. An ontology of the subject matter is necessary for the test. With a good ontology, errors, hallucinations, and deliberate lies can be detected and avoided.

Questions for Gary Marcus

12:46:10 From bhaugh : Can you recommend any specific approaches to combining symbolic and neural AI?

12:49:48 From ToddSchneider : Where does context fit into the ‘landscape’?

12:50:48 From ToddSchneider : Where does 2nd (or higher) order cognition or reasoning come into play?

12:52:47 From Gary Berg-Cross : Are you familiar with the Sci American article: "How AI Knows Things No One Told It" (MAY 11, 2023 BY GEORGE MUSSER) and if so what did you think of its approach to its claims back then?

Questions and Comments for John Sowa

13:14:40 From Janet Singer : John addresses the language pragmatics as well as semantics. How much of a mistake was it to assume a ‘semantic web’ could be successfully developed without the context of the pragmatics?

13:23:13 From ToddSchneider : Should images be considered ‘symbols’?
13:32:16 From Janet Singer : @ToddSchneider Don’t want to answer for John but diagrams could be icons as opposed to symbols which need rules of a language for interpretation/use (after Peirce)

13:26:29 From Phil Jackson : what about the mental models of people who are blind from birth? are these models based on 2-d images or instead based on 3-d models of spatial volumes, or 4-d models of spatial volumes moving in time? Or some other kind of model, that also includes sounds?

13:33:23 From Gary Marcus : Sorry I have to go! Thanks for having me! and I am very sympathetic to most of what John said!

13:34:42 From Gary Berg-Cross : A friendly "central executive" needed to align with some of "our" values gets us into the vague area of social concepts.

13:39:27 From Marco Neumann : Verisimilitude seems to be the predominant goal for the current generative AI effort. And in our media mediated world this may be a sufficient threshold after all. But if AGI is a future goal, how would you test it? Isn't the Turing test just a test of believability as well?
