• In this research, we focus on spatial analysis and natural language processing (NLP) techniques to find two elements: “Where (Location)” and “When (Time)” in the biographical data. By linking and showing the extracted information via a GIS system, we built a spatiotemporal system for scholars to study historical issues from different perspectives. We believe that showing placenames on a GIS interface and relevant statements about the placenames on a time-related scale can provide helpful hints to complex research work.
