Click here for the link to the paper

The paper was presented at the IEEE Global Humanitarian Tech Conference (GHTC)

IEEE GHTC focuses on advancing technology for the benefit of humanity. GHTC is an international flagship conference, focused on bringing together people working on the application of technology to addressing critical issues for the benefit of the resource-constrained and vulnerable populations in the world. It is a forum where IEEE works with developers and NGOs to identify the most pressing needs. We encourage participants from academia, for-profit and non-profit businesses, governmental and non-governmental organizations to attend and present research, ideas, and other considerations for the creation of effective humanitarian technology. We also invite participants to share case studies and lessons learned from deployment and application of humanitarian technologies.

We describe Malasakit 1.0 (meaning “sincere care” in Filipino), a customizable participatory assessment platform that collects and streamlines quantitative and qualitative analyses and insights of disaster risk reduction (DRR) strategies. While supervised classification approaches offer opportunity to understand qualitative textual suggestions, those methods break down in areas like the Philippines, home to 187 languages and nuances in varying socioeconomic contexts. Instead, Malasakit uses dimensionality reduction and peer-to-peer evaluation on qualitative textual suggestions to identify locally appropriate DRR strategies. We present results from 12 field tests conducted in eight distinct geographic locations in the Philippines. 998 participants provided 7,157 evaluations on flood and typhoon preparedness and 2,481 peer-to-peer ratings on 896 textual suggestions for how local government could improve DRR strategies. Results suggest that female participants are more confident than males in their community’s ability to recover from a major typhoon. High-rated textual suggestions focus on issuing immediate early warnings and cleaning drainages to reduce flooding. Malasakit can be accessed at
