Oxford, United Kingdom: January 22, 2025 – Oxford Semantic Technologies (OST), the knowledge-based AI technology company acquired by Samsung Electronics Co., Ltd, has today unveiled the application of its RDFox® technology for use in the newly launched flagship Galaxy S25 smartphone.
RDFox® is the technology behind Samsung’s Personal Data Engine to create hyper-personalised user experiences, while ensuring privacy and security of data on the device. Using knowledge graph technology to integrate and connect data, RDFox® enhances the understanding of how people use a product or service and enables rapid information retrieval and recommendation – making it a crucial tool for realising sophisticated and personalised AI solutions.
In addition, to Samsung’s newest smartphone, the technology giant plans to apply the technology across a wide range of products, including mobile devices, televisions and home appliances.
Speaking at the launch at today’s Galaxy UNPACKED event, Professor Ian Horrocks, Consultant and Founder of Oxford Semantic Technologies said: “We have been developing the technology behind the Personal Data Engine, known as knowledge graph technology. Knowledge graphs provide a natural and powerful way to combine complex data and background information, similar to the way human memory and reasoning works. I like to call this knowledge-based AI. Using knowledge graphs allows computers to better understand information and thereby draw more accurate conclusions and deliver more accurate insights. This can have a huge positive impact on the usefulness of our smartphones and other devices.”
Future solution to AI hallucinations
OST’s knowledge-based AI technology will in the future be used as a solution to a common problem experienced in the adoption of generative AI technology – hallucinations. Businesses and consumers alike are finding that the current deployment of AI technology can often give inaccurate or totally fabricated results. RDFox® addresses this by providing the knowledge base for generative AI to generate answers from.
For OST’s customers, the accuracy of AI applications is often mission critical. Results cannot be left to even the slight probability of inaccuracy, and this is where combining generative AI technology such as Large Language Models (LLMs) with knowledge-based AI delivers the best of both AI technologies – helping LLMs to speak the truth based on fact rather than fiction.
OST provides its technology to a wide variety of companies and industries across a range of use cases - everything from integrating vast amounts of data across organisations to autonomous complex decisions and recommendations in financial services, automotive, manufacturing, healthcare, publishing and retail.
Peter Crocker, CEO of Oxford Semantic Technologies said: “We are delighted to be working with Samsung to provide their S25 customers with even more sophisticated personalisation, integrated with Samsung’s leading AI user experience. We see an exciting opportunity for the adoption of knowledge-based AI technology to enhance the accuracy of AI applications being developed by major organisations across the world. In this and other applications our technology will impact and enhance everyday lives.”
About Oxford Semantic Technologies Ltd.
Oxford Semantic Technologies (OST) is a spin out of the University of Oxford’s computer science department that was acquired by Samsung in 2024. Founded by leaders in the field of knowledge-based AI, OST’s AI software RDFox® enables highly complex questions to be answered precisely and instantly. By combining data with expert knowledge, RDFox delivers more accurate and reliable results than a large language model (LLM). Now deployed within Samsung’s Series 25 smartphones, the software is trusted by a growing list of global clients, including some of the world’s largest banks, leading manufacturing and automotive companies, and global retail brands.

The team behind Oxford Semantic Technologies started working on RDFox in 2011 at the Computer Science Department of the University of Oxford with the conviction that flexible and high-performance reasoning was a possibility for data-intensive applications without jeopardising the correctness of the results. RDFox is the first market-ready knowledge graph designed from the ground up with reasoning in mind. Oxford Semantic Technologies is a spin-out of the University of Oxford and is backed by leading investors including Samsung Venture Investment Corporation (SVIC), Oxford Sciences Enterprises (OSE) and Oxford University Innovation (OUI).
