2. Process of AI4U-class Natural Language Understanding

The AudListen module is alert for auditory input.

Listening for input can be passive, as in the ghost.pl AI and MindForth for robots, or event-driven, as in the JavaScript Ghost.html AI.

AudInput sends phonemic characters to the AudMem module.

AudRecog recognizes concepts already known to the AI.

AudInput sends recognized concepts to OldConcept and unrecognized concepts to NewConcept.

EnParser calls InStantiate to create a new node of a concept.

InStantiate creates a time-bound instance of a concept.

EnParser retroactively creates associative tags.

3. Proof of AI4U-class Natural Language Understanding

Once an AI4U-class AI Mind has understood a sentence of input in natural language, the asking of questions about the knowledge in the sentence and the discussion of the idea in the sentence can ddemonstrate proof of Natural Language Understanding. The SpreadAct module for spreading activation makes the AI able to respond properly to various formats of questions about an understood sentence.

4. Problem of Natural Language Understanding

According to Wikipedia, Natural Language Understanding is an AI-hard problem.

6. Spread the News on TikTok and Other Venues

Are you on TikTok? Are you eager to be a ThoughtLeader and Influencer?
Create a TikTok video in the following easy steps.

I. Capture a screenshot of https://ai.neocities.org/NLU.html
for the background of your viral TikTok video.

II. In a corner of the screenshot show yourself talking about the NLU solution.

III. Upload the video to TikTok with a caption including all-important hash-tags which will force governments and corporations to evaluate your work because of FOMO -- Fear Of Missing Out:
