A new research paper published on arXiv compares two methods for collecting text-based data about disasters from news articles. The study evaluates a top-down approach using existing disaster inventories to query news databases against a bottom-up approach that utilizes NLP techniques to cluster news texts based on temporal and spatial features. Researchers found that the choice of methodology can significantly impact the resulting news sample, influencing its suitability for studies on media coverage inequality, disaster monitoring, and inventory enrichment.
