diagrams.html shows a Theory of Mind.
The Oldconcept module takes a word that has been recognized as
a known concept and creates a new, up-to-date associative node
that preserves the instantaneous relationship of each concept to
nearby concepts caught up in the momentary syntactic assertion.
Typically a verb mediates the relationship from one concept to
another in the knowledge base (KB) that builds up over time as
the accumulation of all known facts and ideas about a concept.
Likewise the concept of any given verb is also mediated by its
associative relationships within myriad syntactic assertions.
In our Open Source AI epistemology, machine learning is the
gradual build-up of an ontology of intricately related facts.
We claim that the AI Mind is theoretically an improvement upon
the vaunted Cyc (R) ontology because we conceptualize concepts
in accordance with the SourceForge/ Mind/ Docs/ Theory of Mind
based on sound neuroscience and the linguistics of Noam Chomsky.
Our AI algorithm includes not only machine learning but also
forgetting -- as the consignment to oblivion of memories that
fail to be brought forward in the stream of consciousness for
lack of associative renewal on the basis of frequency of use.
2. NIL NOVI SUB SOLE
There is "nothing new under the sun" when we generate a sentence,
because the Chomskyan syntax of thought may only manipulate old
concepts already known to the mind but not new concepts until the
newConcept module converts them -- immediately -- to old concepts.
Then the oldConcept module processes the reentry of the output of
the mind back into the mind, reactivating each recognized concept
in chains of association so that spreading activation constitutes
a chain of thinking or meditating or mulling about old knowledge.
If the mind goes down a road less traveled in the conceptual wood
so as to think up an entirely original idea (E = mc^2, anybody?),
then perhaps that original idea has made all the difference.
The diagram ai4u_157.html is a flowchart of Mind.

5. ANALYSIS OF THE MODUS OPERANDI
The Oldconcept module creates a new associative node for a
concept in the mindcore array Psi and also in the En
English lexical array that manipulates English words stored
in the Aud array of the auditory memory channel.
6. EXERCISES FOR STUDENTS OF ARTIFICIAL INTELLIGENCE
6.1. In a new AI or an old AI in a new robot, stub in the module
just to assemble the skeletal framework of the ingredient modules
of a thinking mind. Next, flesh out the oldConcept module. Then
try to improve upon previous versions and release the new species.
6.2. Put enormous national, global, galactic or cosmic databases
at the service of an advanced, superintelligent AI so that the AI
will feel a sense of recognizing or remembering information that
it has never really encountered before. For instance, a sentry
AI might encounter a human face or a biometrics marker that makes
the AI suddenly "know" the entire life-history and psychometric
constellation of the person in question. Such an intuitive AI is
not a priori all-knowing but is rather all-referencing or able to
grok all phenomena by being tied into all known knowledge-bases.
6.3. Achieve and demonstrate the sort of Vulcan mind-meld which
logic dictates should be possible when two artificial Minds pool
their shared memories or knowledge-bases and co-experience events
such as dreams, hallucinations or the remote sensing of scenery.
Establish protocols for deciding questions such as which entity
shall lead the stream of consciousness in the virtual or shared
reality of the mind-meld, and who shall remember and who shall
forget all that transpires during the merging of consciousness.
