An NPC AI framework that uses a linguistic modeling and context-free grammars to parse sentences, store knowledge, deduce information, and plan, all using human readable sentences. I plan for it to be used in a game similar to Chris Chrawford's Siboot, but in a more interpretable language.
You can see it in action here:
And you can hear my full explanation of the system in this 5-minute video!
- Universal Grammar based parsing of sentences into the "Knowledge Graph" representation (see video)
- First order logic for determining the entailments and truth status of parsed sentences
- Parsing if-then sentences (implications) into "rules"
- Planning system (using GOAP algorithm) that can create a plan to make a sentence true using a relevant subset of known "rules"
- Utility based goal/emotional state generating system, using Mazlow's hierarchy (#1)
- Salience ratings for knowledge in the knowledge graph to determine situational relevance of knowledge
- Social behavior system that performs certain conversational acts (Informing, asking questions/seeking information, requesting favors) (#5)
- Authoring content using the system!

Since starting grad school, I've paused work on this project to make some simpler games for my portfolio. But I'll be back to this eventually! It's a really exciting system.
