Investigated Research Topics Spatio-Temporal Data Analysis Frameworks that Operate on Continuous Functions, such as Density Functions and Interpolation Functions. Spatial and Spatio-temporal Clustering and Hotspot Discovery Algorithms Emotion and Emotion Change Mapping Design of Animations that Summarize the Change of Emotions of for a Region of Interest over a Period of Time St^2: Tools for Spatio-temporal Storytelling Also: Create a Website that makes our emotion analysis and animation services available to the public. Not so much: We mostly rely on tools, designed by other, for the assessment of emotions expressed in text document; e.g. tweets; that is, this subject is not the main focus of our research.

Tweet Barometer and ST-Animation Research Given a set of tweets with the location (longitude and latitude), time they were posted and their emotional assessment in [-1,+1] (+1:=very positive emotions, 0:=no emotions, -1: very negative emotions) Research Goals: Identify spatial regions of highly positive emotions (e.g. average emotional assessment >0.4) and regions of highly negative emotions (e.g. average emotion assessment < -0.4) for an observation period; e.g. a year. Identify spatial regions of high discrepancies in emotions (variance of the emotional assessment values is high for the tweets in the region) for an observation period. Identify dominant topics in the tweets identified in steps 1 and 2. Capture temporal patterns of the evolution of the regions identified in step 1 and 2 including: Continuity over time Disappearance / Appearance of new regions Growth / Shrinkage Seasonality Drastic Variations in Emotions in Short Periods of Time … Convert results found in steps 1, 2, 4 into movies/animations that capture the spatio-temporal evolution of emotions in an observation region (e.g. Texas, US,…) over a period of time (e.g. 5 years, 1 year, 1 month): kind of facilitating (spatio-temporal) data storytelling; similar to: https://www.ted.com/talks/hans_rosling_asia_s_rise_how_and_when
