  2. 2. European Parliament as Linked Data • Goal: publish the plenary debates of the European Parliament as Linked Open Data • Why is this important? A. Large scale analysis across time spans B. To residents of the European Union access to the proceedings of the European parliament is a formal right. • Linked Data: a format for publishing data on the Web, with URI’s as permanent identifiers, designed for connecting pieces of data.
  3. 3. Data 14M statements about the 30K speeches by 3K speakers in 1K session days that were held in the EU parliament between 1999 and 2014
  4. 4. Links Country names Members of Parliament Members of Parliament + Parties Members of Parliament Online database with background information about MEPs: “committee, party group and delegation membership, as well as leadership positions” [An Automated Database of the European Parliament.

  5. 5. Example 1: speeches that contain a certain keyword Query: all speeches that contain the phrase “open data” …. So let us go for open data, let us go for utilisation of all the instruments available to that end! ….. …. but there too governments are encouraging the use of open data to increase transparency, accountability and citizen participation …. …. We already have many open data projects in the Member States and local authorities…..

  10. 10. Discussion: What happens if we use linked data as source data for research?
  11. 11. • • Implications for use? Credibility • Who created it? How? • The quality may vary: • EP vs. Wikipedia Completeness • How complete is it? Is there a way to tell how complete it is? • Completeness may vary: • EP vs. wikipedia Update frequency • When was the data last updated? • Update frequency may vary: • EP vs. “An automated database of the EP” Credibility, completeness, update frequency of the links • Who made them? How? When? How complete are they? Message: the need for dataset evaluation is exacerbated when using linked data
  12. 12. How to use this data, in practice The bad news: we don’t have a friendly user interface :’( ! ! ! ! The good news: our data + all sources we link to are openly available for everyone :) ! ! Options for use: 1. Tell us what you want to know and we will write you a query. 2. Go to our website, copy-paste an example query into the query editor. 3. Go to our website, write a SPARQL query in the query editor ! 4. Query our SPARQL endpoint programmatically. ! Website: via data/
  13. 13. Use of the data during three Creative Camps • 3 events of one week each, where people are invited to work with our data on-site. ! • Outcome CC #1 in Hilversum: • Links to the Italian parliament. • Detection of people who speak about an unusual mix of topics. • Sentiment analysis
