5. Fast Interestingness Hotspot Discovery
Objective: Find interesting contiguous regions in spatial data sets based on the domain expert’s notion of interestingness which is captured in an interestingness function
Methodology:
Transform Dataset Into Graphs
Identify hotspot seeds
Grow seeds by adding neighboring objects
Remove redundant hotspots using a graph-based approach
Find Scope of hotspots (polygonal boundary detection)
Data sets: Gridded, polygonal, point-based data sets
People: Chong Wang, Arjun SV, Qian Qiu

7. Investigated Research Topics EMOA&St2
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: The long term goal is to 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 documents, such as tweets; that is, this subject is not the main focus of our research.

14. 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:
