Internet of Things (IoT) and Open Big Data Research
Internet of Things (IoT) is a key information technology that connects real-world objects with the Internet. Together with a university team in the US and UK, Charles conducted research applying IoT in the construction management domain. The project built a system using wireless sensors to monitor the real-time condition of confined work environments. The sensor data was fed into Building Information Modeling (BIM) platform. The integrated IoT-BIM system provides a solution for real-time visualized decision-making to help reduce construction hazards in confined spaces, thus improving construction safety.
In the big data domain, Charles looked specifically at the significant amount of public data that are open and released by the governments. Proper usage of these data is expected to create enormous social and commercial value as well as improve civil governance. Unleashing the true power of these data requires a clear understanding of its ecosystem. With a team at Columbia University, this research surveyed the global open data landscape by taking into account the Open Data Barometer (ODB) ranking system and its three sub-indexes - readiness, implementation, and impact. The research also compared and analyzed the open data landscape on the basis of income levels of the ODB ranked countries and produced recommendations on enhancing the ecosystem.
