Hi,
sorry for the lack of documentation, I'm really close to be done with
the backward chainer implementation and then I'll write a detailed
documentation.
Regarding true query, it is ATM no different than a variable query, and
yet it works! Specifically it can answer true queries where the fitness
function would be to maximize confidence, that is because the PLN rules,
as currently implemented almost only get applied when they increase
confidence.
There is a place holder for a fitness function that I'll implement when
needed.

I mean -- to be clear -- this question should have a step-by-step
analysis on a wiki page, to illustrate how R2L and PLN actually deal
with it. The fact that we don't have such a page is a major issue.

Its not a trivial question, I'm sorry no one answered your email
earlier. Nil works on this component, I am not sure how it works or
how well it works right now.

Hi everyone,
So I've been trying to figure out the steps of inference the
bc/fc will do in order to answer the following TruthQuery:

Soo, about this part:

(EvaluationLink
(DefinedLinguisticPredicateNode "Truth Value")
(EvaluationLink
(PredicateNode

What do the nested EvaluationLink here mean?
And what steps will the bc follow to ground the variable to this
(if that's how it works):
|
(EvaluationLink
(PredicateNode "won@349785b2-b0c2-4feb-bd51-29d7fffefc73")
(ListLink
(ConceptNode
"Japan@2d483477-9a2d-4049-968f-8f7120f43e51")
(ConceptNode
"game@85e71213-577b-4aa2-8412-da49e62ba2f4")

I appreciate any help on this! (and sorry if these are trivial
things)
