Logic maps for legislative drafters, CRLP2025

We've made a demo video of how legislative drafters can produce simple if-then versions of drafts, for automatic conversion to L4. Legalese's visualiser (jl4.legalese.com) automatically turns the L4 into an interactive map of the logical structure of the draft provision. See youtu.be/_VZ4_FY_Nqo

Interesting post on Kurt Cagle’s Substack “The Ontologist” open.substack.com/pub/ontologi.... Gives equivalent of our “AI sandwich” (osf.io/8v5bd) for how people now use LLMs with knowledge graphs - LLM translates human’s English question for KG, then translates KG's answer into English for human.
