Xfinity xFi & User Personalization with Graphs

The text discusses the development of Comcast's xFi smart home prototype, which aims to create a truly interactive and helpful home environment. The team identified key challenges, including semantic and social relationships between devices, people, and locations. To address this, they developed a rich definition of what a person and home are, using graph data structures and native graph databases. This allows for automation and personalization based on real-life relationships and context. The xFi prototype includes tools such as Kidwatch and Porchcam, which notify users when their children arrive home from school or when the doorbell rings. The system also uses GraphQL APIs to provide a flexible and expressive API for developers. Ultimately, the goal is to create a smart home that can learn and adapt to the user's needs, making it easier and more rewarding to live in a connected home environment.
