Using European Data in Journalism
Barr, Caelainn
The European Union is awash with numbers. Data about how european citizens live and our taxes are spent are widely available - the challenge lies in using them. Figures are published on a centralised, national and regional basis with little in common. Data formats, presentation and quality vary greatly. How can we use this information as citizens and journalists to understand the union and generate stories? Why should journalists and developers work together to look at European data? Using practical and live examples of data use including commission expenses and structural funds we will demonstrate how to get EU data, how to prepare it for analysis, the trends to look out for and how to translate it into a story.

This talk will address questions like: What is the potential of data journalism? Why is it relevant to society? Why is data journalism not just about reporting and news organisations and why should you care about it?

Map of criminality in Prague
Cibulka, Jan
I plan to show how the Prague Crime Map was created. The starting point was data published officially by the Police, followed by a more specific database, which I requested from the Police. We will look at the first attempt to visualize the data, which failed spectacularly. On this example I will demonstrate the importance and necessity of analysis before data requests and project launching. I will also show how the second version of the map was created in cooperation with the Czech Statistical Office. Finally, demonstration of final data refining and its visualization will be shown. The map itself should be more accurate than the current map of crime compiled by the Police (the project is still running, final version should be ready by the end of August).
