Wikipedia Pages Processed
ODKE+ efficiently processes millions of web pages, prioritizing Wikipedia for its quality and freshness, ensuring a vast corpus for fact extraction.
At the heart of ODKE+ is a sophisticated LLM-based extractor, guided by ontological structure to ensure semantic consistency and accuracy.
Ontology-Guided Prompting
The LLM-based extractor dynamically generates ontology snippets tailored to each entity type. These snippets include predicate names, descriptions, required qualifiers, and acceptable units, guiding the LLM to produce structured, semantically-aligned outputs.
This method ensures schema-aware fact extraction and broad applicability across diverse entity types without requiring customized configurations, adapting flexibly to both structured and unstructured web content.

Reduction in Hallucinated Extractions
The lightweight Grounder module, utilizing a second LLM, plays a critical role in verifying extracted facts against their source context, significantly reducing hallucinations.
Grounding and Corroboration for Trustworthiness
To combat the inherent hallucination risks of LLMs, ODKE+ integrates a dedicated Grounder module that uses a second LLM to judge context alignment. This ensures facts are explicitly supported by evidence.
The Corroborator further refines extracted facts by normalizing, consolidating, and scoring them based on extractor type, confidence, frequency across sources, and richness, achieving 98.8% precision in production.
ODKE+ represents a significant advancement over prior versions and traditional KG methods, delivering unparalleled freshness, coverage, and reliability.

Reduced Update Lag (Average)
Newly extracted facts appear significantly earlier than in legacy KG workflows, ensuring the knowledge graph remains exceptionally fresh and relevant.
Real-world Deployment & Performance
ODKE+ has been deployed in a production KG infrastructure since May 2025, handling both batch and near-real-time streaming updates. It processes 150-250K new facts per day for high-priority entities with an end-to-end latency under 2 hours.
Consistent weekly audits demonstrate >95% factual accuracy, and its extensibility allows new predicates to be integrated declaratively, maintaining 99.9% success rates.
Acknowledging the complexities of AI, ODKE+ is designed with several ethical safeguards, focusing on data provenance, transparency, and minimizing unintended biases.
Addressing Bias and Data Privacy
While relying on LLMs trained on broad web data, ODKE+ includes grounding and corroboration to mitigate bias propagation. It exclusively processes public sources like Wikipedia and extracts only explicitly stated facts, avoiding user-generated content or private data, and preventing suppositional inference or hallucinations.
Its design prioritizes verifiable and contextually anchored knowledge, adding a crucial layer of factual control.
Hybrid
Extraction Strategy
Optimized for efficiency, ODKE+ uses lightweight pattern-based extractors where possible, and LLMs selectively based on data complexity, reducing computational intensity and environmental impact.
