An analytic expression of language is any expression of formal or natural language that can be proven true or false entirely on the basis of a connection to its semantic meaning in this same language.

This connection must be through a sequence of truth preserving operations from expression x of language L to meaning M in L. A lack of such connection from x or ~x in L is construed as x is not a truth bearer in L.

    It would then be possible to reconstruct the antinomy of the liar
    in the metalanguage, by forming in the language itself a sentence
    x such that the sentence of the metalanguage which is correlated
    with x asserts that x is not a true sentence.

To the extend Prolog formalizes anything, that only formalizes
the condept of self-reference. I does not say anything about
int.

It may seem that way if you have no idea what
(a) a directed is
(b) what cycles in a directed graph are
(c) What an evaluation sequence is

More relevanto would be what a "truth-maker" is.
Anyway, it seems that Prolog does not say anything about
truth-bearers because Prolog does not say anything about
truth-bearers.

Which are (like logic) for the most part truth preserving.
If (A & B) then A
 Logic where the infoerence rules are for the most part truth prserving
is not useful. They all must be.
 
For some cases
Prolog offers several operations letting the implementation to
choose which one to apply.

I don't thing so. Once the Facts and Rules are specified
Prolog chooses whatever Facts and Rules to prove x or not.
It is back-chained inference.
 Standard Prolog is what the Prolog standard says. Conforming implementations
may vary if the standard allows. If you think otherwise you are wrong.
There are also non-starndard Prlongs that vary even more.
 
The fundamental architectural overview of all Prolog implementations
is the same True(x) means X is derived by applying Rules (AKA truth preserving operations) to Facts.
That is the way that all expressions X of language L are determined
to be true in L on the basis of the connection from X in L by truth preserving operations to the semantic meaning of X in L.
{Linguistic truth} is the philosophical foundation of truth
in math and logic, AKA relations between finite strings.

Consequently some goals may evaluate
to true in some implementations and false in others, for example
>
 L = [L].
 No matter what you think this is an example. It is outside of the intended
application area but not prohibited.
