SPIDER — Symbolic Planning and Inference

Abstract

SPIDER is a graph‑driven geotechnical intelligence engine that fuses symbolic inference with cost‑aware planning. Heterogeneous inputs are parsed with NLP and mapped onto a domain symbol set, then reasoned over a knowledge graph using uniform‑cost search. A PostgreSQL‑backed dynamic memory enables human–AI collaboration and explainable workflows; computation blends Python/SymPy for exact algebra, fuzzy logic for uncertainty handling, and reinforcement learning for policy refinement.

SPIDER — Abstract

SPIDER is a graph‑driven geotechnical intelligence engine that combines NLP‑based parsing, symbolic inference with SymPy, and cost‑aware planning over a knowledge graph via uniform‑cost search. A PostgreSQL‑backed dynamic memory supports human–AI collaboration and explainable AI, while fuzzy logic and reinforcement learning refine decisions under uncertainty.

📥 Data Ingestion
Spider accepts any geotechnical input: lab results, sensor data, satellite imagery, practitioner notes, documents, or external APIs.
🔄 Translation to Σ
All inputs are normalized into Spider's shared geotechnical symbol set (Σ) - a unified vocabulary for consistent reasoning.
🎯 Provider Selection
The system intelligently selects the best combination of physics laws, empirical models, and ML algorithms from its curated registry.
📊 Auditable Results
Every decision includes full explanation: which providers were used, why they were chosen, confidence levels, and complete audit trail.
