Abstract: More and more studies are based on freely available social media data. Using microblogs, a midpoint between instant messaging and content production, analyses of urban activities are possible. This paper focuses not only on mapping human activities but also on defining urban function in the city. Using geotagged Twitter data, the research carried out separate spatial and temporal analyses, in conjunction with combined spatio-temporal analyses. Tweets were categorised into six activity groups: Working, Eating, Shopping, Leisure, Home and Education, based on selected keywords. The results show stronger performance for the detection of Leisure, Eating, Shopping and Education activities and less successful performance for Working and Home activities. The first four cluster near the centre of the city, while the rest are scattered all over the city. Moreover, each activity shows its own temporal pattern. This study finds characteristic patterns for everyday activities and shows the possibility of using social media data to define urban function for places where land-use information is not available. Keywords: geotagged Twitter data, spatial analysis, temporal analysis, urban data, social media Published Online: 2020/06/25 07:45:19 Object Identifier: 0xc1aa5576 0x003b9d74 Rights:https://creativecommons.org/licenses/by-nd/4.0/
GI_Forum publishes high quality original research across the transdisciplinary field of Geographic Information Science (GIScience). The journal provides a platform for dialogue among GI-Scientists and educators, technologists and critical thinkers in an ongoing effort to advance the field and ultimately contribute to the creation of an informed GISociety. Submissions concentrate on innovation in education, science, methodology and technologies in the spatial domain and their role towards a more just, ethical and sustainable science and society. GI_Forum implements the policy of open access publication after a double-blind peer review process through a highly international team of seasoned scientists for quality assurance. Special emphasis is put on actively supporting young scientists through formative reviews of their submissions. Only English language contributions are published.
