From Text to Political Positions. Text analysis across disciplines

Geplaatst op 13-05-2014 door Maarten Marx | DiLiPaD, ExPoSe | tags: | Geen reacties »

The book From Text to Political Positions. Text analysis across disciplines edited by Bertie Kaal, Isa Maks and Annemarie van Elfrinkhof recently appeared.
It contains chapters by DiLiPaD researchers Graeme Hirst and Maarten Marx.

Abstract

From Text to Political Positions addresses cross-disciplinary innovation in political text analysis for party positioning. Drawing on political science, computational methods and discourse analysis, it presents a diverse collection of analytical models including pure quantitative and qualitative approaches.Dilipad-logo-REVERSED-300dpi By bringing together the prevailing text-analysis methods from each discipline the volume aims to alert researchers to new and exciting possibilities of text analyses across their own disciplinary boundary.
The volume builds on the fact that each of the disciplines has a common interest in extracting information from political texts. The focus on political texts thus facilitates interdisciplinary cross-overs. The volume also includes chapters combining methods as examples of cross-disciplinary endeavours. These chapters present an open discussion of the constraints and (dis)advantages of either quantitative or qualitative methods when evaluating the possibilities of combining analytic tools.

Digging into Parliamentary Data Tutorial

Geplaatst op 08-05-2014 door Maarten Marx | DiLiPaD, ExPoSe | | Geen reacties »

Jaap Kamps and Maarten Marx (both University of Amsterdam) will give a tutorial at Digital Libraries 2014, London, called Digging into Parliamentary Data.
Date: Monday, 8th September.

Dilipad-logo-REVERSED-300dpiThe tutorial will show how to incrementally annotate textual corpora, starting from OCR’ed flat text to encoding structure and entities, and demonstrate the remarkable power of such light-weight semantic annotation: linear text becomes valuable research data that can be sliced and diced to present many views.

This tutorial is part of the Digging into Linked Parliamentary Data (DiLiPaD) and Exploratory Political Search (ExPoSe) projects.

Text of tutorial proposal.
Additional tutorial material (Slides, links, etc).

PoliticalMashup and Parliamentary Data

Geplaatst op 16-04-2014 door Maarten Marx | DiLiPaD, parliament | | Geen reacties »

The PoliticalMashup project at the University of Amsterdam started collecting parliamentary proceedings in 2008. We started with Dutch proceedings and have since moved to collecting proceedings from other European states as well. Dilipad-logo-REVERSED-300dpi
Our aim is to transform all proceedings into a rich common XML format and store these into a single XML database system. With this database system we facilitated comparative diachronic research for historians, political scientists, linguists and communication scientists.
Currently we collect data from The Netherlands, the UK, Flanders, Germany, Denmark, Sweden and Norway.
The main problem in keeping the collecting up to date and going back as far as possible is changing data formats. The content and layout of the proceedings are in general very stable over time, but the technical formats differ much, especially in the “digital era” (starting roughly around 1995). For older material, OCR errors and badly placed scans form major challenges. Besides these challenges with the texts, much work is needed to recognize, disambiguate and link political entities (speakers, parties, constituencies, ministerial functions, etc) to existing databases.

Aims

After consultation with a panel of users consisting of scientists, journalists and archivists we decided to focus on the following aims:

  • create a complete copy of the proceedings of the meetings in parliament;
  • add metadata which record for each word spoken in parliament when it was said, who said it, in what role, on behalf of which party, and in which context. If possible, also indicate the type of speech act (e.g., speech from central lectern, interruption of a speech, shout from the benches, etc);
  • give each entity a unique identifier which is resolvable by a Handle system comparable to the DOI system; do this for real entities (persons, parties) and textual objects (proceedings, topics, speeches, paragraphs, votes, etc);
  • use these identifiers to link data to existing databases and link the parliamentary data to the Linked Open Data Cloud.

Available tools

Proceedings of the UK and the Netherlands are actively collected “until yesterday”. The collections start in 1935 (UK) and 1814 (NL) respectively. They can be downloaded and accessed through a Search Interface.

Cooperation

DiLiPaD’s Dutch principal investigators Jaap Kamps and Maarten Marx collaborate with the Information Office of the Dutch House of Commons, the Dutch Royal Library, the Dutch National Archive, the Dutch Documentation Centre for Political Parties, and scientists from the Humanities, Social and Computer Sciences.

Linking Hansards to related newsarticles

Geplaatst op 15-04-2014 door Maarten Marx | DiLiPaD, ExPoSe, ODE, parliament | tags: | Geen reacties »

We describe a simple technique with which to link news articles to debates in Parliament.
The technique uses the news search engine EMM Newsexplorer.
As search strings we use

  • the date of the debate
  • the speakers
  • the first ten words from a unigram parsimonious language model created from the debate

Results on oral questions are promising. In this post we explain how we find the relevant news articles, evaluate the results. Code is provided.
