Artificial Intelligence

We're pioneering AI to make healthcare universally accessible 
and affordable.

Down

Babylon is helping to solve an increasing range of healthcare challenges with artificial intelligence.

Our AI has been designed around a doctor’s brain to provide accessible healthcare for millions in the palm of their hands. It can understand and recognise the unique way that humans express their symptoms. Using this knowledge, combined with a patient’s medical history and current symptoms, it provides information on possible medical conditions and common treatments.

  • How our AI works

    A committed team of research scientists, engineers, doctors and epidemiologists are working together to develop and optimise Babylon's AI abilities. Much of the team’s work is on the development of cutting edge machine learning research; this is being driven through access to large volumes of data from the medical community, continual learning from our own users and through feedback from Babylon’s own experts.

    There are a number of different systems behind our AI, all working together to provide a fast, effective, reliable, and safe system for our users.

  • The knowledge graph and user graph

    Babylon’s Knowledge Graph is one of the largest structured medical knowledge bases in the world. It captures the whole of human knowledge on modern medicine encoded for machines. We use this as the basis for Babylon’s intelligent components to speak to each other. The Knowledge Graph keeps track of the meaning behind medical terminology across different medical systems and different languages.

    While the Knowledge Graph provides the general knowledge about medicine, particular patient cases are kept in the User Graph. Coexistence of the Babylon Knowledge Graph and the User Graph allows for more discovery. We can match diagnoses with treatments and symptoms with outcomes, constantly improving our understanding of patients so we can offer more effective and efficient information.

  • The inference engine

    Simply understanding how users express their symptoms and risk factors is not enough to identify and provide reasons about the underlying set of diseases. At the heart of Babylon’s AI is our inference engine, a powerful set of machine learning systems, capable of reasoning on a space of >100s of billions of combinations of symptoms, diseases and risk factors, per second, to suggest possible underlying conditions. The inference engine provides our AI with the ability to provide reasoning efficiently, at scale, to bring healthcare to millions.

  • Natural Language Processing (NLP)

    Our AI can’t provide information to patients if it can’t understand them, and patients won’t use our AI if they can’t understand it. To help bridge the gap, we use Natural Language Processing (NLP). NLP helps computers interpret, understand, and then use everyday human language and language patterns. It breaks both speech and text down into shorter components and interprets these more manageable blocks to understand what each individual component means and how it contributes to the overall meaning, linking the occurrence of medical terms to our Knowledge Graph. Through NLP our AI can transcribe consultations, summarise clinical records and chat with users in a more natural, human way.
