Levente Juhasz and Henry Hochmair are presenting research at the 2019 GI_Forum in Salzburg, Austria. The paper is entitled, “Comparing the Spatial and Temporal Activity Patterns between Snapchat, Twitter, and Flickr in Florida.”
Abstract: Social media services generate enormous amounts of spatiotemporal data that can be used to characterize and analyze user activities and social behavior. Although crowd-sourced data have the advantage of comprehensive spatial and temporal coverage compared to data collected in more traditional ways, the different social media platforms target different user groups, which leads to user selection bias. Since data from social media platforms are used for a variety of geospatial applications, understanding such differences and their implications for analysis results is important for geoscientists. Therefore, this research analyzes differences in the spatial and temporal contribution patterns to three online platforms, namely Flickr, Twitter and Snapchat, over a period of six weeks for Florida. For the comparison of spatial contribution patterns, a set of negative binomial regression models are estimated to identify which socio-economic factors and characteristics of the built and natural environment are associated with contribution activities. The observed contribution differences are discussed in light of the targeted user groups and different purposes of the three platforms.
