On May 11, 2019, The two working papers written by the team of Disaster Risk Reduction Knowledge Service System of IKCEST, “Extraction and Analysis of Earthquake Events Information based on Web Text” and “Disaster Metadata Management System Based on pycsw and Its Application”, are published in IRDR Working Paper Series, which is a new publication of Integrated Research on Disaster Risk (IRDR).
The members of Disaster Risk Reduction Knowledge Service System of IKCEST, studied disaster event acquisition from Web text and disaster metadata standards based on DRR platform. Those two studies have published in in IRDR Working Paper Series on May 11, 2019, with the titles of “Extraction and Analysis of Earthquake Events Information based on Web Text” and “Disaster Metadata Management System Based on pycsw and Its Application”, respectively.
“Extraction and Analysis of Earthquake Events Information based on Web Text”
This study explores the automated spatiotemporal and attribute information extraction of earthquake events from web news reports and online official reports in China from 2015 to 2017. Combined with a web crawler, natural language processing, and geographic information science, a set of rules is created to automatically extract spatiotemporal and attribute information for earthquake events from web text, and geocoding is applied to map the earthquake events. The spatial and temporal distribution characteristics of earthquake events extracted from the web texts are then analyzed. This study compares the differences between web news reports and online official reports in terms of the quantity and spatiotemporal distribution of the earthquake events.
“Disaster Metadata Management System Based on pycsw and Its Application”
Based on open source pycsw software, this study establishes mapping of disaster core metadata standard, Dublin core metadata standard, and ISO 19115 geographic information – metadata based on an independently-designed disaster metadata standard. The disaster metadata management system is designed and analysed to realize the functions of online adding, editing, viewing, deleting, and data downloading of disaster metadata. The prototype system developed in this study is preliminarily applied to the Disaster Risk Reduction Knowledge Service System of the International Knowledge Center for Engineering Sciences and Technology (IKCEST) (https://ikcest-drr.osgeo.cn/).
