Smart navigation with AI Engine for Li-Fi based Medical Indoor Environment

Abstract

Fourth industrial revolution is developing worldwide. Internet of Things(IoT), Big Data, and Artificial Intelligence(AI) technology, which are the core of the 4th industry, provide the navigation service in the indoor space. In this paper, we use a Light Fidelity(Li-Fi) Access Point(AP) installed in a dense network to collect accurate location information and create a traffic map. The AI engine using the hospital integrated information database suggests a smart indoor navigation system that uses Joint Named Entity Recognition and Disambiguation(J-NERD) to conveniently enter the symptoms and guide the user to the desired location by matching diseases.
