Dealing with problems in Russian be-verbs

As we start constructing the InFerence mind-module in Strawberry Perl 5, we enter the Russian statement "МАРК СТУДЕНТ" for "Mark is a student", but the AI does not create a be-verb after the subject. When we type in "ОН СТУДЕНТ" for "He is a student", we do indeed get the provisional be-verb. When we type in "РОБОТ СТУДЕНТ" for "The robot is a student," we do indeed get the instantiated be-verb, so perhaps the problem involves the use of a new concept instead of old, known concepts. (Now we are spreading "liquid paper" on the individual keys of the keyboard, because we need to write the Russian Cyrillic letters on each key.) When we first introduce the name with "He is Mark" and then "Mark is a student" in Russian, we do get the imputed be-verb. It turns out that we need to declare the $seqneed variable already carrying a value of "8" for expecting a verb, because the basic Parser module has not yet been called to set the value.

Proposing to consolidate the parsing functionality

We may be able to eliminate the original Parser() module by transferring its functionality to EnParser() for English and RuParser() for Russian.

Consolidating parser functionality into EnParser() and RuParser().

The original Parser() module starts with a $bias of "5" to expect a 5=noun. Then Parser() switches to a $bias of "8" to expect an 8=verb, after which the $bias switches back to "5" again, although an incoming noun could be an indirect object or a direct object. It may be possible to move the preposition-handling code and the object-handling code up into the Parser() module renamed as the EnParser() for English and the RuParser() for Russian.

We start a few versions back by renaming as so that we may skip some unstable intervening code. Into the Parser() module we drop the EnParser() code dealing with English prepositions and with indirect and direct objects. Then in the InStantiate() module we comment out the now obsolete call to EnParser. The new composite code of does not properly register the indirect object of "BOY" in "I make the boy a robot."

Although in we switched names between Parser() and EnParser(), now we will reverse the switch because we no longer want there to be simply a Parser() module, but instead for there to be both EnParser() for English and RuParser() for Russian. We need the separate modules for English and for Russian, because, for instance, English has to deal with "DO" as an auxiliary verb, but Russian does not deal with an auxiliary verb "DO". First from we pick up the old RuParser() module and drop it into the AI. In OldConcept() and in NewConcept() we make the necessary changes for calling EnParser() and the still simple RuParser().

We should now upload the code to the Web for several reasons, before we debug the problem of failure to register an indirect object. Firstly, much code has been renamed and commented out. When we resume coding, we may clean up the new code by removing the old detritus. Secondly, it is vitally important to present the Ghost Perl AI as having the straightforward separation of EnParser() and InStantiate() because the consolidated parser functionality, that comprehends prepositions and both indirect and direct objects, holds the key to the Mentifex claim that "AI has been solved" inasmuch as the enhanced parser enables each AI Mind to demonstrate major progress against the problem of natural language understanding (NLU) which various published articles on the Web describe as an untractable problem and as a last main obstacle to True AI.
