SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Enables structured, auditable reasoning over knowledge graphs by applying deductive, abductive, and rule-based methods to derive, justify, and hypothesize about facts.

Core Features & Use Cases

  • Deductive reasoning: derive new conclusions from known facts using formal rules.
  • Abductive reasoning: generate and rank plausible explanations for observations.
  • Query-based reasoning: evaluate Datalog and SPARQL programs against the graph.
  • Explainability: provide clear justifications and provenance for all conclusions.
  • Use Case: diagnose data gaps and infer missing links in a knowledge graph for auditability.

Quick Start

Ask it to run a deductive query to infer missing relations from your graph.

FAQPage Schema
How do I perform deductive reasoning over a knowledge graph to infer missing facts?

Abductive reasoning generates and ranks plausible explanations for observations in a knowledge graph. It formulates hypotheses to diagnose data gaps and infer missing links based on available evidence.

Can I evaluate SPARQL and Datalog programs against a knowledge graph for query-based reasoning?

Yes, you can evaluate Datalog and SPARQL programs against your knowledge graph. This query-based reasoning processes structured rules to derive facts and validate logical relationships across the graph data.

What is the best way to generate and rank plausible explanations for knowledge graph observations?

Abductive reasoning generates and ranks plausible explanations for observations in a knowledge graph. It produces ranked hypotheses to help diagnose data gaps and infer missing links based on available evidence.

How does explainable reasoning justify conclusions derived from a knowledge graph?

Explainable reasoning provides clear justifications and provenance for all conclusions derived from a knowledge graph. It ensures every deductive or abductive inference is auditable by tracking the formal rules applied.

When should I use Rete-based reasoning versus standard deductive queries over my graph?

Rete-based reasoning efficiently processes rules through a forward-chaining engine, suitable for complex pattern matching. Standard deductive queries derive specific conclusions from known facts using formal logical rules applied directly to the graph.
