MNR-Air: An Economic and Dynamic Crowdsourcing Mechanism to Collect Personal Lifelog and Surrounding Environment Dataset. A Case Study in Ho Chi Minh City, Vietnam

摘要

This paper introduces an economical and dynamic crowdsourcing mechanism to collect personal lifelog associated environment datasets, namely MNR-Air. This mechanism's significant advantage is to use personal sensor boxes that can be carried on citizens (and their vehicles) to collect data. The MNR-HCM dataset is also introduced in this paper as the output of MNR-Air and collected in Ho Chi Minh City, Vietnam. The MNR-HCM dataset contains weather data, air pollution data, GPS data, lifelog images, and citizens' cognition of urban nature on a personal scale. We also introduce AQI-T-RM, an application that can help people plan their travel to avoid as much air pollution as possible while still saving time on travel. Besides, we discuss how useful MNR-Air is when contributing to the open data science community and other communities that benefit citizens living in urban areas.
