That makes the problem harder. You still have to somehow deal with different word-senses for "apple", and in addition, you also need to create a a model of the mental state of id1. So, if id1 is a child, the word-sense for "apple" and "sweet" is probably different than if id1 is an iphone fanboi.

[opencog-dev] Re: word2vec within openCog language learning?

My quick, informal gut-feel sense of this is that the right answer is to replace "vector" part of word2vec by that *actual data structure* that *actually occurs in language". It's kind of hard to explain how to do this, but let me give it a whirl. Note how vectors are "symmetric", in the sense

Re: [opencog-dev] Should we encode the basic cognitive procedures (initial version at least) or they will spring out automatically?

Hi Alex, I'm hoping for a two-prong approach for some of the simpler stages of what you talk about: hand-coded rules, for now, to get some things going, and then also some automatically-learned ... uhh .. things. The hanson-robots chatbot consists of multiple parts, some of which are very

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,

I assume that this is a bug somewhere, in the example, or wherever, and Nil is the one to look at it. If this is in regard to a block of code in some examples directory, open a bug report. If you want to be totally awesome then track down the bug, and provide a patch? --linas On Fri, Apr

Re: [opencog-dev] Best texbook (most relevant to Opencog Node and Link Types) in Knowledge representation

I don't know that book but it's probably adequate. Opencog contains a potpourri of ideas from logic, prolog, lambda calculus, relational algebra. There's usually several ways to solve any problem in opencog. Many or most of the link types in opencog are not used for basic KRR, but are there to

Re: [opencog-dev] Re: Best texbook (most relevant to Opencog Node and Link Types) in Knowledge representation

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"

Containers? I also do not want to clobber my current system install, and so I frequently use containers (lxc or docker) for running foreign environments. This may be too much to ask for pasberry pi, and migh be daunting if you are not yet familiar with lxc or docker (they're not hard, but it

while you are defining modules, you are in a module context, and that is confusing. Best to work at the top level, and not inside of any module at all. (for c++ this would be like calling main inside of a function ... it would just be .. weird) On Thu, Mar 9, 2017 at 5:27 AM, Alex
