Knowledge graph - Scientific news
Sopra Steria has unveiled a specialized "Graph AI" framework designed to resolve "Temporal Blindness" and "Hierarchical Logic" errors in Large Language Models (LLMs) within the legal sector. Announced on January 19, 2026, the technology utilizes multi--dimensional knowledge graphs to map the complex relationships and effective dates of federal and supranational laws. For the corporate and public sectors, this breakthrough enables "Regulatory Reasoning," allowing AI agents to provide legally accurate advice by grounding model outputs in the structured hierarchy of legislative authority rather than simple semantic similarity.
