Using parameters to declare the time-points of conceptual instantiation.

[2019-10-02] Recently we have expanded the conceptual flag-panel of MindForth from fifteen tags to twenty-one associative tags, so that the free open-source artificial intelligence for robots may think a much wider variety of thoughts in English. Then we had to debug the function of the InFerence module to restore its ability to reason from two known facts in order to infer a new fact. For instance, the Forthmind knows the fact that students read books, and we tell the AI the fact that John is a student. Then the AI infers that perhaps John, being a student, reads books, and the incredibly brilliant Forth software asks us, "Does John read books?" We may answer yes, no, maybe or no response at all. Currently, though, we have the problem that InFerence works only once and fails to deal properly with repeated attempts to trigger an inference. We suspect that some of the variables involved in the process of automated reasoning are not being reset properly to their status ex quo ante before we made the first test of InFerence. Therefore we shall try a new technique of debugging which we have developed recently in one of the other AI Minds, namely the ghost.pl AI that thinks in both English and in Russian. We create a diagnostic display at the start of the EnThink module for thinking in English, so that we may see the values held by the variables associated with the InFerence module and the KbRetro module that retroactively adjusts the knowledge base (KB) of the AI Mind in accordance with whatever answer we have given when the AskUser module asks us to validate or contradict an inference. The following dialog shows us that some variables are not being properly reset to zero.

john is student

EnThink: becon= 1 yncon= 0 ynverb= 0 inft= 0
qusub= 0 qusnum= 1 subjnom= 504 prednom= 561 tkbn= 0
quverb= 0 seqverb= 0 seqtkb= 0 tkbv= 0
quobj= 0 dobseq= 0 kbzap= 0 tkbo= 0
DOES JOHN READ BOOKS
no

EnThink: becon= 0 yncon= 0 ynverb= 0 inft= 2084
qusub= 504 qusnum= 1 subjnom= 0 prednom= 0 tkbn= 2086
quverb= 863 seqverb= 0 seqtkb= 0 tkbv= 2087
quobj= 540 dobseq= 0 kbzap= 404 tkbo= 2088
A JOHN DOES NOT READ BOOKS

EnThink: becon= 0 yncon= 0 ynverb= 0 inft= 2118
qusub= 504 qusnum= 1 subjnom= 0 prednom= 0 tkbn= 0
quverb= 863 seqverb= 0 seqtkb= 0 tkbv= 0
quobj= 0 dobseq= 0 kbzap= 0 tkbo= 2088
PROFESSORS TEACH THE STUDENTS AND STUDENTS READ THE BOOKS

EnThink: becon= 0 yncon= 0 ynverb= 0 inft= 2152
qusub= 504 qusnum= 1 subjnom= 0 prednom= 0 tkbn= 0
quverb= 863 seqverb= 0 seqtkb= 0 tkbv= 0
quobj= 0 dobseq= 0 kbzap= 0 tkbo= 2088
I UNDERSTAND YOU AND YOU ARE A MAGIC
andru is student

EnThink: becon= 1 yncon= 0 ynverb= 0 inft= 2220
qusub= 504 qusnum= 1 subjnom= 501 prednom= 561 tkbn= 0
quverb= 863 seqverb= 0 seqtkb= 0 tkbv= 0
quobj= 0 dobseq= 0 kbzap= 0 tkbo= 2088
DOES ANDRU READ THE STUDENTS

Because some of the variables have not been reset, a second attempt to trigger an inference with "andru is student" results in a faulty query that should have been "Does Andru read books?" Let us reset the necessary variables and try again.

Upshot: It still does not work, because of a more difficult and more obscure bug in the assignment of conceptual associative tags. Well, back to the salt mines.

[2019-10-04] We may have made a minor breakthrough in the InStantiate module by doing one instantiation and by then using parameters such as part of speech (pos) and case (dba) to declare the initial time-points for subjects, verbs and objects. The EnParser module may then retroactively alter or modify the associative tags embedded at each identified time-point.
