• Spans 1780-2010• 1828 reports on 1599 events• Events have category (assassination, riot, etc.) and
motivation (race, military, labour, etc.)• The data is messy

Initial Visualisation
This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 644055.
Google Maps Visualisation
This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 644055.
• Source data has specific location information (eg Tangipahoa, St. Helena Parish, LA)
• Initial uplift only captures some of this (LA – Louisiana)• Capturing more specific locations improves data quality• How do we discriminate?
Improving data quality
This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 644055.
• Solution – semi-automated processes• Automated processes identify the most likely match
candidates• Humans then choose the correct candidate• Created two tools for semi-automated geographical data
improvement• Table-based• Map-based• Rajan Verma, TCD MSc student

Improving data browsing
• Initial implementation of USPV browsing• Does not provide users with a way to visualise data spatially• Looks dull
This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 644055.
Improving data browsing
• Balazs Pete, TCD MSc student• Allows users to easily select interesting subsets of data• Users can visualise spatial relations• Easy to use
