We present a new fully-symbolic Bayesian model of semantic parsing and reasoning which we hope to be the first step in a research program toward more domain- and task-general NLU and AI. Humans create internal mental models of their observations which greatly aid in their ability to understand and reason about a large variety of problems. We aim to capture this in our model, which is fully interpretable and Bayesian, designed specifically with generality in mind, and therefore provides a clearer path for future research to expand its capabilities. We derive and implement an inference algorithm, and evaluate it on an out-of-domain ProofWriter question-answering/reasoning task, achieving zero-shot accuracies of 100 thereby demonstrating its value as a proof-of-concept.
