Patent #2026902371 · 2026-03-19

Education Intelligence Material System

Educational content globally is fragmented and inconsistent. This patent protects an end-to-end pipeline: extracting structured knowledge from any document format, building a reasonnable knowledge graph, and maintaining accuracy through self-healing mechanisms.

Why This Patent Matters

Three bottlenecks in global EdTech

Fragmented Knowledge

Textbooks, courseware, and question banks are scattered across PDFs, scanned images, and handwritten notes. Unstructured formats, no annotations, machine-unreadable. Current OCR solutions have extremely low extraction rates for formulas, charts, and complex layouts.

Non-Deterministic Reasoning

LLM-generated educational content carries hallucination risk — incorrect formulas, wrong knowledge associations, skipped solution steps. Education demands accuracy far beyond typical conversational AI.

Uncontrollable Quality

Once a knowledge base is built, how do you detect errors? How do you ensure cross-subject consistency? Current approaches rely on manual review — expensive and low coverage.

Design Philosophy

Three principles ensuring structured, deterministic, and self-healing knowledge

Structure First

All knowledge stored as structured graphs, not text fragments. Each knowledge point has unique ID, subject, difficulty level, prerequisites, and linked assessment items. This makes reasoning a deterministic graph traversal, not probabilistic LLM generation.

Deterministic Reasoning

Given identical inputs, the system always produces identical reasoning paths and results. This is not LLM inference — it is formal reasoning over knowledge graphs, where every step traces to specific knowledge points and association rules.

Self-Healing Validation

The system continuously scans for inconsistencies: circular dependencies, orphan nodes, cross-subject contradictions. When defects are found, the repair pipeline triggers automatically and generates audit reports.

Six Core Technologies

Technical innovation at every stage of the end-to-end knowledge pipeline

Multi-Modal Document Parser

Vision AI extraction from textbooks and documents — math formulas (LaTeX/handwritten), charts, tables, mixed layouts with >95% accuracy. Works with educational documents in any language

Automated Knowledge Graph Construction

Automatic knowledge network from extracted content: subject classification, difficulty grading, prerequisite mapping, cross-subject associations. 15,000+ knowledge points indexed and verified

ESR Super-Resolution Pipeline

Two-stage local processing: high-speed extraction + AI super-resolution enhancement. Handles real-world materials: low-quality scans, phone photos, degraded prints. 100% gate validation pass rate

Deterministic Reasoning Engine

Knowledge graph-based formal reasoning: given problem → identify knowledge points → graph traversal → generate solution path. Results are verifiable, traceable, not probabilistic LLM output

Self-Healing Validation Pipeline

Continuous knowledge base scanning: circular dependencies, orphan nodes, cross-subject contradictions, version conflicts. Auto-triggers repair on defect detection, generates audit reports

Adaptive Assessment Engine

Dynamically adjusts assessment difficulty and content based on knowledge graph and learning trajectory, precisely identifying knowledge gaps and generating personalized learning paths

Production-Verified Scale

Not a paper prototype — a production system validated with millions of materials

K-12 Education Platforms

Structured knowledge bases and deterministic reasoning for global K-12 platforms. Verified knowledge graphs replace LLM hallucinations, ensuring every teaching recommendation is grounded in validated knowledge

Enterprise Training & Knowledge Management

Structured extraction and knowledge graph construction from internal documents (compliance manuals, SOPs, technical docs). Self-healing validation keeps the knowledge base in sync with source documents

Publisher Digital Transformation

Batch conversion of printed textbooks to structured digital assets. Multi-modal parser handles formulas, charts, complex layouts; ESR pipeline enhances low-quality materials

Adaptive Learning Systems

Deterministic reasoning drives personalized learning paths from knowledge graphs. Unlike LLM-driven approaches, reasoning results are replayable, explainable, and auditable
