Hi Ivan, I think best if you can spend a bit time on working on a few representative examples that shows what you can do with your embedded language. AI discussions tend to get very abstract, very quickly :-), so to "engineer" ground ourselves its best to talk by way of examples. This helps hi

Daniel/Ivan, It is quite obvious we are not really in OpenCog territory here, but what your discussion is hinting at is that you will need your own theory of meaning, or theory of the meaning of meaning. At the conceptual level my approach begins where Linas left off, ie there is no meaning ind

Mr. Daniel Gross, I'm afraid I'm going to leave the juicy AGI details to AGI developers (not to say it is an easy part, far from that). I decided to be just a technical guy, if anyone is interested in my low-level solution of programming language that equally easy (or hard) solves application deve

Hi Ivan, thank you for your response. Pattern matching is a very general purpose mechanism -- in my mind key questions are: what governed the language for pattern description and the semantics of how patterns match with inputs what governs the language of transformational rules, triggered b

Hey Daniel, great to see someone interested in AGI :) How about us, humans, I mean how do we think? I'm not trying to resemble our neural networks, I took another, top-down approach, in between, but let's observe us as an thinking example. Do we see how our thoughts are formed? I think that we don

Hi Ivan, Your work sounds very exciting ... would be great to hear more about it. I think one issue with the approach you are describing is that you have to assume the knowledge of a second language and a mapping, in principle, from the first to the second. I think systems that aim to self-

Yes Linas, thank you for response. That is why there is no exclusively definite interpretation of any expression. Expression "space" can be translated to numerous meanings, with each meaning having its own, slightly different interpretation in its own language. If we think about "Multiverse", notio

Ivan, I mostly agree (superficially) with most of what you are saying, but: I notice you avoid or over-simplify the issues mentioned in the wikipedia article "upper ontology". The points are two fold: different human beings have subtley different "upper ontologies", they tend to change over time,

Hi all :) May I say a few words about semantics? In my work on describing knowledge, I've concluded that a semantics (meaning) of an expression is merely an abstract concept of thought that relates the expression to its interpretation in another (or the same) language for which we already know its

Hi Linas, Thank you for your responses, and the pointer. It seems to me that your example further pin-points my question: A quasi-linear walk through a semantic network is essentially a constructed structure (or path) through the use of grammar, to get at a possible reading of a sentence tha

Semantics and syntax are two different things. Syntax allows you to parse sentences. Semantics is more about how concepts inter-relate to each other. -- a network. A sentence tends to be a quasi-linearized walk through such a network. For example, take a look at the "deep" and the "surface" struct

As I see it, the meaning of a word can be understood as the fuzzy set of patterns in which that word is involved... Some of these will be purely language-internal patterns (as highlighted by Saussure and other structuralist linguists way back when), others will be patterns associating the word wit
