Summary

Symbolic informalization reliably converts formal mathematics into natural language, making machine-checked content human-readable without losing precision. This process generalizes syntactic sugar mechanisms in traditional proof systems, extending them into the ordinary language of mathematics. For proofs constructed by artificial intelligence and autoformalization, symbolic informalization can precisely explain the generated content. The Informath project aims to demonstrate how this technique can produce fluent, productive, and multilingual text with reasonable development effort. Informath employs an interlingual architecture, utilizing Dedukti as a central hub to connect various proof systems like Agda, Lean, and Rocq. Grammatical Framework (GF) then handles linguistic correctness and variations across different natural languages, ensuring broad applicability.

Key takeaway

For research scientists or NLP engineers developing AI systems that generate mathematical proofs, you should consider integrating symbolic informalization techniques. This approach ensures that complex, machine-checked content remains human-readable and explainable without sacrificing precision. Projects like Informath, which uses an interlingual architecture with Dedukti and Grammatical Framework, can streamline the development of fluent, multilingual explanations for formal systems like Agda, Lean, or Rocq.
