Transform data and knowledge into fast and accurate answers to complex questions.

Rules-based artificial intelligence powered by human-like reasoning and the highest performing knowledge graph technology.

RDFox, the high-performance knowledge graph and rules based AI is developed by Oxford Semantic Technologies.
RDFox is cutting-edge technology, continuing development after spinning out of the University of Oxford.

What makes us different?

Oxford Semantic Technologies was born out of decades of research into Knowledge Representation and Reasoning (KRR) by three professors at the University of Oxford Computer Science department, including Professor Ian Horrocks, winner of the BCS Lovelace Medal, awarded in recognition of his significant contributions towards reasoning systems.

Why is our proprietary technology unique?

Powerful AI

Creating knowledge from data.

Just like we reason as human beings, RDFox has been built from the ground up as a rules-based reasoning engine. Delivering the most powerful reasoning for AI applications where accuracy, truth and explainability are essential.

RDFox can deduce and build new knowledge based on facts, not fiction.

RDFox is a knowledge graph database, storing data in a network structure.
RDFox is the world's most performant knowledge graph and semantic reasoning engine.
High Performance

Lightning speed.

The only knowledge graph that operates in-memory, RDFox consistently out performs other graph technologies in benchmark tests by many orders of magnitude.

Designed to handle the largest knowledge and data stores, up to billions of triples with huge complexity, where real-time results and high availability are key.

Why RDFox?

Enterprise features at the heart of RDFox applications.

High Performance

The in-memory design produces 10-1000x faster results than other graph databases and enables enterprise-level scaling.

High Availability

Avoid downtime—keep your solution online 24/7, 365 days a year, with RDFox's high availability setup.

Access Control

Who can and can't access data is always a top priority, so RDFox gives you complete control.

Explainability

Unlike other AI, RDFox is logic-based, so guarantees truth, accuracy, and auditability.

Human-like reasoning

RDFox’s unique semantic reasoning draws human conclusions, enabling the efficient extraction of powerful insights.

Data Import & APIs

We offer data import options from multiple sources and a RESTful API for flexible connectivity.

RDF Knowledge Graph

We use the open RDF standard to make it easier to transfer your data between RDF triple stores.

Expert Knowledge

We provide access to our expert knowledge engineers as standard, supporting your project along the way.

Incremental Reasoning

RDFox’s reasoning makes updates as soon as data is added or removed without impacting performance or requiring a reload.

RDFox Applications

The use of rules-based AI and knowledge graph technology is rapidly becoming prevalent across multiple industry sectors, covering a vast range of applications. Our clients are leveraging the power of RDFox to solve today’s greatest challenges.

Semantic Search and Personal Recommendations with Knowledge Graphs and AI - dark.

One of the biggest frustrations for consumers and business experts alike is the inability to find the precise product or information that they are looking for, only to be recommended products or information that are unhelpful and irrelevant. RDFox delivers accurate results not seen in other AI or conventional technologies.

Regulatory compliance and rules with knowledge graphs and rules-based AI - dark.

Regulated industries, including financial services and healthcare, face increasing pressures to make decisions based on complex rules and regulations. Compliance is vital to protect consumers and institutes alike against financial fraud and cybercrime. RDFox delivers instant decisions and detection based on complex rules and patterns.

Product configuration and compatibility management with a knowledge graph - light image.

Many manufacturers and retailers face the headache of providing customers with compatible product configurations in real-time, whether it is matching furniture or millions of possible permutations of engineered components. RDFox delivers immediate and optimal solutions to turn complex into simple.

Drive autonomous vehicles with knowledge graphs and AI.

Whether piloting a car, truck, aircraft, or boat, a challenge facing all autonomous systems is the ability to make the correct and immediate decision every time. Speed of thought is critical in any autonomous vehicle application, and RDFox’s advanced reasoning and on-device capabilities provide the brain of a safe, explainable and accurate platform.

RDFox support data management and can import and export in many formats via the shell, UI or API - dark.

Over the last decade, the abundance of data has become a obstacle in and of itself. Today, the true challenge lies around consolidation and analysis—finding valuable knowledge in a sea of information. RDFox does exactly that, enabling rapid data integration and advanced analysis.
