Towards Data Science is a community-powered publication that showcases work in data science, machine learning and artificial intelligence. Every day newcomers, seasoned researchers and industry practitioners publish tutorials, research notes and real-world case studies that help the field move forward.

Towards Data Science

Healthcare leads in knowledge graph adoption due to its scientific foundation in empirical observation, which naturally supports ontological thinking. The industry benefits from a deep culture of controlled vocabularies and classification, reinforced by strict regulatory requirements that demand standardized terminology and replicable evidence. Pre-competitive collaboration, sustained public funding from agencies like NIH, and early adoption of open data standards (W3C) enabled the creation of shared semantic infrastructure. These factors combined over decades to make knowledge graphs inevitable rather than optional in healthcare, creating the world's most mature semantic infrastructure.
