Abstract
The proliferation of social media has resulted in its extensive use as a valuable source of information for researchers. This paper aims to use Twitter data to analyze and visualize tweets about the migration crisis in the European Union from 2016 to 2021. The paper uses a methodology to structure data for better understanding of complex social media data. The methods and metrics include the facet model of location based social media, the HyperLogLog data structure and novel uses of the metric typicality. The authors have also developed a web based interactive application closely following the methodology used to organize the dataset. Additionally the work also includes maps using spatial typicality which could be utilized for studying spatial phenomenon. The case study selected also provides unique insights and sets a template for working with multi-lingual geo-social media data. The authors believe that these methods and metrics could be reproduced for other case studies and aid in understanding and communication geo-social media data.

期刊介绍:
KN - Journal of Cartography and Geographic Information is dedicated to theoretical, applied and empirical approaches of cartography and geovisualization. We understand cartography as a science and technique to analyze, visualize and communicate spatial information. Cartography is the cross-over discipline in the field of spatial and geo sciences, including geoinformation science. Cartography addresses spatial questions from a variety of disciplines, including geography, environmental sciences and social sciences, using methods and tools developed at the interface with neighboring domains such as geodesy, GI Science, and spatial cognition.These questions can put different emphasis on theoretical fundamentals, methods, techniques and applications.KN - Journal of Cartography and Geographic Information is the only cartographic journal of the German language area. The journal is among the oldest cartographic periodicals worldwide. It was established in 1951 as the journal of the German Society of Cartography (DGfK). In 1976, the journal has become the joint periodical publication of DGfK, the Cartographic Commission of the Austrian Geographical Society (ÖKK), and the Swiss Cartographic Society (SGK).The journal publishes four issues per year. All articles are peer-reviewed. Furthermore, there are short articles on recent technical developments in practical applications with geodata. The journal reports on national as well as international conferences and other events concerning the above-mentioned fields. Supplementary sections comprise regular accounts of the activities in the German, Austrian and Swiss cartographic societies and business news from private-sector-companies, government agencies and academia. In addition, there are book reviews and a calendar of cartographically relevant events. Since 2009, the journal is indexed in Scopus.
