Wed.15.SEP.2010 -- Progress on Predicate Nominatives

In frustration we want to know one thing. Why can't the 14sep10A.F MindForth answer "I AM ANDRU" when asked immediately "what are you", but it can indeed state that answer if the user first makes some different input, like the word "I"?

In December of 2009 and January of 2010, when we were coding who-queries and what-queries, we were not yet using neural inhibition, and so we may have made our code overly complicated. For example, on about 19jan2010 we used a SubjectClear module to zero out subject concepts after the input of a query. If we rely on InHibition instead, we may get an immediate answer to a query, after which the answer-idea goes briefly into InHibition and lets one or more additional answers be thought up by the AI.

All right, fellow cyborgs. We went into the VerbPhrase module and we commented out the InHibit code both before and after the call to SpeechAct, because the pre-SpeechAct code inhibits the idea that has just been resurrected from the knowledge base (KB), and the post-SpeechAct code inhibits the new idea that has just been uttered. Immediately (although we do not know why) our AI began to function better in the answering of "What are you?" queries. We had the following conversation with the MindForth AI Mind.

Human: you are a program Robot: PROGRAM IS PROGRAM

Human: what are you Robot: PROGRAM

Human: what are you Robot: I AM ANDRU

Human: what are you Robot: I AM PROGRAM

A ".psi" report indicates that only nouns were being inhibited, not verbs.

Btw (nerdspeak for "by the way"), we just enhanced our AI program considerably with a little trick. We did not like seeing the AI say, "I AM PROGRAM", so we decided to reinstate a call from the VerbPhrase mind-module to the EnArticle (English article) module. This time, however, we inserted the EnArticle call just before the main VerbPhrase call to SpeechAct, and we set up IF-THEN conditionality to call EnArticle only for a predicate nominative. Immediately the AI began saying "I AM AN ANDRU" and "I AM A PROGRAM". Somehow we feel that this same enhancement brings us closer to Is-a considerations and to the logical treatment of sets and classes.
