Is there an example of text input and rule output from the relex2logic ? 
Thanks.

If you mean "do we model other people's beliefs?" that answer would have to
be "I wish". We still have multiple severe fundamental problems with
creating and manipulating models of the world: It's still hard to wrap up
into one big ball the fact that blob 42 in the visual field is a human face
and its name is billy-joe-bob and the last thing bliiy said was foobar,
which implies that billy believes that foobar. This is well beyond what we
can do from first principles.

But, many corporations, e.g. advertisers e.g. cambridge analytica most
infamously has developed a psychological model of hundreds of millions of
Americans, and what they believe. Their model is crude, full of mistakes,
and not based on first principles, but it is a model which they claim was
used to elect Trump.  You (or we) could hack up something like this too,
but "hack up" is the keyword here: we'd rather try to be more organic, more
first-principles-driven.

I don't know the specifics of that but I assume that it stores it as 
someone's belief rather than its own. Then PLN can in principle modifies 
the system's belief, assuming for instance that the person holding the

Yeah, I've seen that diagram :) I posted one about how I am planning to
implement this chatbot however it didn't post correctly, here it is
(Hopefully it works this time)


Thanks




Three short comments:

1) PLN is a set of rules that run on top of the rule engine. Those
rules, when triggered, alter the "truth values" on atoms in certain
ways. You (or someone) should be able to create a different set of
formulas for truth values, that emulate the NARS formulas. You could
then run PLN deductions side by side with NARS deductions, and see
which you like better (or even create yet other kinds of formulas)

2) we have "relex2logic" rules, which convert natural language to
logic expressions. These are ... time-consuming to write, and by
nature are incomplete and buggy -- because natural language is a
fluid, changing thing. Hand-writing rules is a good exercise, but
madness lies in that direction.

3) the current diagram of how things connect is kind-of-ish reviewed
here:

Hi, I am new to Opencog and hopefully building a chatbot with it
soon, I was going to use OpenNARS but after some reading I am
convinced that PLN > NARS

So here are my questions:

1 I am thinking of writing rules that convert input text to a
understandable format for Opencog, I am aware that this has
already been done with the NLP pipeline
However from what I've been told rules that for example convert
"that" into what is meant with "that" aren't implemented yet.

Example: Tim: My computer keeps crashing
Tim: I hate that
This rule would turn this into : Tim said that Tim hates that
his computer keeps crashing (In atomese)

This is just one example of such a rule.

2 I should've asked this before but are such rules even helpful?
And is atomese even the language in which such things would be
inputted to the system?
I am extrapolating from OpenNARS in which input like this is
done in Narsese but I am not sure how that works in Opencog yet...

3 What does MOSES do exactly? And is it needed for a chabot? (I
know what MOSES does with the evolution of mini programs, I am
just not quite sure on what those mini programs do..)

That's all of the questions I could think of right now, not sure
if I missed one (hopefully not)

The chatbot I am building will use an up board which will run
Opencog, that should be okay right?

It didn't show did it, hopefully this works.. This is bad because this 
really is an unimportant diagram in comparison to my other questions 
however now it seems like I am making it look important (Which it isn't) 
because It didn't post correctly.
