2. Purpose of the AI4U Textbook Indicative Mood Module

The Indicative sub-module serves to isolate the superior EnThink module from the inferior thought-generation modules, so that the output of a conjunction from the ConJoin module may engender the calling of more than one idea at a time, joined by one or more conjunctions.

3. Algorithm of the AI4U Textbook Indicative Mood Module

3.A. The basic algorithm of the Indicative mind-module is the calling of the EnNounPhrase and EnVerbPhrase modules to make a simple statement in the indicative mood.

3.B. The Indicative module includes code for the special case of suppressing the recall of low truth-value ideas when the AI Mind is trying to announce what it actually knows, or believes to be true, after the ConJoin module has inserted the conjunction "THAT" in advance of making a statement as an assertion of knowledge on the part of the AI.

3.C. An additional but merely provisional algorithm within Indicative is the setting of conceptual activation values so as to cause the AI artificially to state "I DO NOT KNOW" in response to an input query for which the AI does not know the answer to the query.

5. Variables for the Indicative Mood AI Mind-Module

$act -- quasi-neuronal activation-level

$bias -- EnParser(); NewConcept(): expected part-of-speech POS

$chaincon -- chain-of-thought condition-flag

$conj -- a dual-purpose variable serving both as an identifier of which particular conjunction is under consideration for use by the ConJoin module, and a control-flag for the decision of whether to call the Indicative module more than once.

$dunnocon -- is a flag used in SpreadAct() to permit the Mind-in-a-Box to respond to a who+verb+object query with "I DO NOT KNOW" if no correct answer is found.

$hlc -- human-language code; 1=en; 2=de; 3=ru. Subject to override by the $engov or $degov or $rugov flag.

$ictus -- testable activation-level to trigger use of a conjunction by the ConJoin() module in expressing a compound thought composed of two or more strongly activated ideas, each generated by a single calling of the Indicative() module.

$idea -- for re-entry of AI thought back into the AI.

$moot -- – as in legally moot – is a flag to prevent the formation of associative tags during mental operations which are not truly a part of cognition, such as the processing of an input query, the formation of a silent inference, or the creation of an output query.

$nounlock -- time-point in conceptual memory for a verb to lock onto a seq-noun.

$pov -- point-of-view: 1=self; 2=dual; 3=alien. When pov=1, the word "you" is somebody in the external word. When pov=2, the word "you" refers to the self-concept "I" in the AI. When pov=3, the word "you" is interpreted as part of a conversation by a third-party or as a word in a text, not referring to the self-concept of either the AI or of someone talking to the AI.

$qucon -- query-condition – segregates SpreadAct() code to respond to the input of who-queries.

$qv1psi -- concept for SpreadAct to seek as a subject, so that the AI will try to remember knowledge about the concept.

$qv2num -- num(ber) of a verb in a who+verb+dir.obj response.

$qv2psi -- concept for SpreadAct to seek as a verb, so that the AI may remember ideas containing the same verb.

$rv -- recall-vector for auditory memory. The time-point value of rv is first set in the AudInput module after an intervening space when the first character of an input-word is being passed into the AudMem module. The recall-vector rv is reset to zero in AudInput after a call to OldConcept or to NewConcept.

$seqpsi -- concept to which activation should be spread in the SpreadAct module for spreading conceptual activation.

$svo1 -- subject -- item #1 in subject-verb-object

$svo2 -- verb -- item #2 in subject-verb-object

$svo3 -- indirect object -- item #3 in subject-verb-object, when item #4 is a direct object.

$svo4 -- direct object -- item #4 in subject-verb-object

$tdo -- time-of-direct-object for a parser module.

$tpr -- time-of-preposition for parsing.

$verbcon -- verb-condition for seeking (in)direct objects. $verbcon is set to a positive unitary one in the EnParser module when a verb comes in during input and remains at one while any indirect or direct object comes in. After an input sentence, $verbcon is reset to zero.

$verblock -- for subject-noun to lock onto seq-verb. The $verblock is a time-point in conceptual @psy memory where the $seq of a subject-noun is located, so that any crucial consideration such as the negation of a verb will be found when the verb-phrase module fetches the verb-concept from memory. If the thinking process finds and activates a particular subject-noun in memory, the $tkb of the subject noun becomes the $verblock so that a particular verb at a particular time will be selected by the English or Russian verb-phrase module.
