The MindForth Programming Journal (MFPJ)
is both a tool in developing MindForth
open-source artificial intelligence (AI)
and an archival record of the history of
how the AI Forthmind evolved over time.
Fri.30.JUL.2010 -- Basket of Problem Behaviors
With each new MindForth AI coding session,
we may reevaluate our list of salient bugs
and issues to work on, importing the old list
and passing it on for the next coding session.
* Query "who are you" works as initial
but not as secondary input.
* Inflectional "S" should be added in NLP,
not in SpeechAct.
* Post who-query AI says "I IS I" instead
of "I AM I".
* EnPronoun needs code to choose "he",
"she" or "it" based on "mfn".
* SpreadAct needs a more general
search-find-exit coding than "zone".
* Mechanism for detection of duplicate
thought needs removing.
* BeVerb requires too strict a word order
to function;
* EnArticle kicks in inappropriately with
proper name ANDRU;
* num(ber) of "IS" gets falsely changed
from "1" to "2";
* Entry of "WE" does not convey idea of "YOU AND I".
* BeVerb supplies wrong form regardless of subject noun number.
Fri.30.JUL.2010 -- Using "fin" to Merge
AM IS ARE Forms
In the 27jul10A.F MindForth we finally obtained
an AI that could engage in man-machine conversation
without major derailments. Perhaps the most glaring
problem right now is that "who are you" is answered
correctly only when it is the initial query.
We want the AI to answer the query properly
at any arbitrarily chosen time.
After a few test runs of the new 30jul10A.F
source code, we see now at least the cause,
but not yet the bugfix, of the glitch where
the AI responds to a non-initial "who am i"
query with "YOU ARE I". The report captured
below shows that the "ARE" verb is acquring
a "seq" tag of 50=I which overrides the
108=MAGIC tag at t71.
367 : 56 39 0 0 107 7 67 56 to YOU
371 : 67 23 0 0 56 8 108 67 to ARE
380 : 108 0 0 0 56 5 0 108 to MAGIC
386 : 55 0 0 0 0 7 67 55 to WHO
390 : 67 23 0 55 55 8 50 67 to ARE
394 : 50 0 0 67 55 7 67 50 to I
396 : 50 0 1 50 0 7 57 50 to I
399 : 57 1 0 50 50 8 33 57 to AM
405 : 33 0 1 57 50 5 57 33 to ANDRU
409 : 55 0 0 33 0 7 67 55 to WHO
412 : 67 0 0 55 55 8 56 67 to ARE
414 : 56 39 1 67 55 7 67 56 to YOU
418 : 56 39 0 56 0 7 67 56 to YOU
422 : 67 47 0 56 56 8 50 67 to ARE
424 : 50 0 1 67 56 7 67 50 to I
time: psi act num jux pre pos seq enx
We are beginning to see that present-tense
forms of the verb "to be" should not have
a "seq" tag, because there is no semantic
relationship between the verb as such and
the predicate nominative. With a transitive
verb, there is indeed such a relationship,
because over time a transitive verb such
as "eat" may have many direct objects.
We are reminded that in Russian, a present-tense
form of "to be" is not even expressed. "KTO OH?",
which looks like "Who he?" in English, fully means
"Who is he?" to the speaker of Russian. In our AI
software, we could leave out the present-tense
forms of "to be" and not suffer any more than
Russian does. However, we would like some sort
of indicator for a verb of being, so that the
BeVerb module may be called.
Here is an idea of the moment. We could have the
"fin" tag of the present-tense forms "AM", "IS"
and "ARE" all go to a verb with psi concept #0
(zero), not as any particular verb form, but as
a flag to call the BeVerb module. Once invoked,
BeVerb shall have the job of selecting the proper
form of "to be" as the output verb.
We went into the Forthmind source code and we
added "BE" at the end of the EnBoo t sequence.
First we consulted our page on AI standards
and we saw 58¾ as a pre-ordained psi-number
for the word "BE". We decided to use concept #58
and not #0 (zero) so as to avoid any problems
where the software might be testing for a
positive (greater-than- zero) psi concept number.
We changed the "fin" (fiber-in) tags on "AM",
"IS" and "ARE" to fifty-eight (58) so that any
such incoming form would activate the #58 "BE"
concept -- even though we would use BeVerb to
reject "BE" as a word of output and select a
proper verb-form instead. We thought that we
would have to go into BeVerb and trap for
concept #58, but apparently BeVerb only traps
for non-BE forms. We ran the AI with two
who-queries, and it worked immediately.

The innovation is such a powerful change to
MindForth, that we need to upload the code
almost immediately. First we would like to
muse that our practice of conducting backwards
searches for recent "seq" and other tags,
means that a pronoun like "YOU" can be
expected "automagically" to refer to the
same person who has recently been interacting
with the AI. In other words, we do not need
immediately to compose code to keep track of
different instances of "YOU" in the environment
of the AI. The "I" pronoun, on the other hand,
can be assumed to refer almost unchangeably
to the AI itself.

Give it up Arthur, if you'd spent the last few decades actually working
on the code as hard as you self-promote you might have achieved something
beyond graduate project level.
