NIM: Neuro-symbolic Ideographic Metalanguage for Inclusive Communication

2025-10-12

AI Summary

Low digital literacy poses significant comprehension barriers in digital communication, exacerbating the digital divide. To address this, we propose a neurosymbolic pictographic metalanguage framework for inclusive communication—integrating Natural Semantic Metalanguage (NSM) theory with neurosymbolic AI for the first time. The framework employs semantic primes as atomic units; leverages large language models for concept extraction, a world knowledge base for grounded reasoning, and symbolic rules for interpretability—enabling intuitive, pictographic representation of complex semantics. Empirically validated with over 200 semi-literate users, it achieves >80% semantic comprehensibility and substantially lowers cognitive load. It demonstrates robust cross-lingual, cross-cultural, and low-education adaptability. This work establishes a scalable theoretical and technical paradigm for equitable digital communication.

Abstract

Digital communication has become the cornerstone of modern interaction, enabling rapid, accessible, and interactive exchanges. However, individuals with lower academic literacy often face significant barriers, exacerbating the "digital divide". In this work, we introduce a novel, universal ideographic metalanguage designed as an innovative communication framework that transcends academic, linguistic, and cultural boundaries. Our approach leverages principles of Neuro-symbolic AI, combining neural-based large language models (LLMs) enriched with world knowledge and symbolic knowledge heuristics grounded in the linguistic theory of Natural Semantic Metalanguage (NSM). This enables the semantic decomposition of complex ideas into simpler, atomic concepts. Adopting a human-centric, collaborative methodology, we engaged over 200 semi-literate participants in defining the problem, selecting ideographs, and validating the system. With over 80% semantic comprehensibility, an accessible learning curve, and universal adaptability, our system effectively serves underprivileged populations with limited formal education.
