Strigil: A framework for data extraction
Zvirinský, Peter
Data scraping is a way to gather and integrate data from different data sources. In this presentation, we will describe Strigil, a framework for automatized screen-scraping. It allows to define custom scraping scripts in intuitive graphical user interface and provides a solution for scalable and distributed scraping.

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).

Google BigQuery and other Google tools for big data
Hráček, Filip
You have a lot of data. You kind of know what you want to do with them, but every operation would take minutes or hours to complete on your machine(s). Google BigQuery, Refine and FusionTables are some of the tools that help you harness the cloud - so you can do complex things with huge data in very short amounts of time.

Collecting the EU's Regional Funds
Lindenberg, Friedrich
One of the key funding mechanisms of the European Union is the Regional Policy, which helps to implement infrastructure projects across the 27 member states. Money is allocated along a set of objectives and disbursed at the regional level, by 60-odd managing bodies. But who is getting the money and what is it really spent on? The answer lies distributed across the local administrations and has only been collected into a common database once, in 2010. It took the TBIJ and Financial Times eight months to gather the information, leading to a series of disclosures about misallocated funds and shady projects. This is why we believe that there should be a constantly-updated database of these reports, maintained by an open community and available as a resource to journalists and policy makers at any time. The right time to start such a data commons, as the 2007-2013 budgetary cycle of the EU is coming to a close and it's time to get a picture of how well the goals set out for 347 billion Euros of funding during this period have been reflected in actual projects. We want to make a map of member states and regions where open data projects are already collecting this data and then form small teams to take on the uncharted terrtories, find PDF reports and to convert them to clean and useable data. So, join the ERDF Ghostbusters and help us to map the European money!
