Conference Presentations 2011

  • IASSIST 2011-Data Science Professionals: A Global Community of Sharing, Vancouver, BC
    Host Institution: Simon Fraser University and the University of British Columbia

B2: The IASSIST SIGDC Presents: Perspectives on Data Citation (Wed, 2011-06-01)
Chair:Mary Vardigan, Inter-university Consortium for Political and Social Research

  • Tracking Data Reuse: Motivations, Methods, and Obstacles
    Heather Piwowar (NESCent, University of British Columbia)


    Rewarding investigators who share data, assessing the impact of data repositories, and measuring the intended and unintended effects of data policy decisions all depend on being able to track dataset reuse. Unfortunately, tracking data reuse is currently extraordinarily difficult due to diverse attribution practices, tool limitations, and data source restrictions. Through a Pecha Kucha overview and subsequent details in a more traditional format, this talk will summarize recent experiences in tracking data reuse. Examples will be drawn from the ongoing project Tracking Data Reuse: Following one thousand datasets from public repositories into the published literature (winner of the 2010 ASIS&T SIGUSE Elfreda A. Chatman Research Proposal Award).

  • Panel Discussion - IASSIST Special Interest Group on Data Citation (SIGDC)
    Robert Downs (Center for International Earth Science Information Network (CIESIN), Columbia University )

  • ICPSR's Efforts to Encourage Data Citation
    Elizabeth Moss (ICPSR)


    With its long-held commitment to linking social science data to the publications based on them, ICPSR has been encouraging stakeholders to make data citation common practice. This presentation will outline ICPSR's efforts to change outmoded citing practices by partnering with other archives to influence the whole community, including researchers, editors, journal publishers, and database aggregators.


B3: Question and Variable Level Discovery and Access (Wed, 2011-06-01)
Chair:Amy Pienta, University of Michigan

  • Creating Personal Extracts While Keeping Confidentiality
    David Schiller (Institute for Employment Research (IAB))


    The German National Educational Panel Study (NEPS) collects longitudinal data for educational research. With six starting cohorts and 60.000 target persons, a more and more complex data structure emerges with every new wave. Data for scientific research is normally offered as flat files with a fixed number of variables and values. Therefore data providers have to build appropriate flat files for the scientific community, which is a difficult manual task as the data structure is complex. New ways to solve the mentioned problem open up when storing the data within a relational database. Variables or sets of variables, out of the entire range of data, can be selected and combined via a user interface similar to a shopping basket system or a "variable browser". The results are exported as individual datasets in different formats that meet the individual needs of researchers (e.g., Stata, SPSS). Database functionality and tools of business intelligence provide a wide range of possibilities to support the researcher during the selection process (e.g., descriptive statistics or metadata information). Confidentiality can be maintained by using a combination of database tools and statistical disclosure control methods (e.g., by using "security levels" for variables, or by using synthetic data).

  • Findings of the original language documentation for the European Values Study (EVS)
    Evelyn Brislinger (GESIS - Leibniz Institute for the Social Sciences)
    Wolfgang Zenk-Moeltgen (GESIS - Leibniz Institute for the Social Sciences)


    The questionnaire of the recent EVS wave 2008 was translated into 38 languages and adjusted to 46 different cultural contexts to ensure that questions measure the same phenomena. This translation process was closely monitored and well documented, and it was the starting point for a workflow designed by GESIS that aims at high quality documentation of data with original question texts. This documentation is valuable for secondary users who want to look at the question wording used in different languages, countries or waves. We presented the ongoing project at IASSIST/IFDO 2009 and are now able to report on the findings. With the full data release of EVS 2008 in December 2010 the documentation process will be finished and the original language documentation will be published through online retrieval systems, an interactive online overview, and English/original language variable reports ( With the release of the longitudinal file 1981-2008 in June 2011 the original questions for two waves will be available and comparisons of questions across time will be possible. The workflow includes long-term preservation of all key information and databases. Also it allows for the re-use of the original language documentation as basis for questionnaire translation of coming waves.

  • Social Science Question Database and Research Tools
    Xavier Schepler (Reséau Quatelet)
    Laurent Lesnard (Reséau Quatelet)
    Anne-Sophie Cousteaux (Reséau Quatelet)


    The increase in the number of surveys archived and disseminated raises new challenges for data archives. Indeed, without new tools, the growth of the number of surveys makes it increasingly difficult for users to identify surveys that are relevant for them. Without new tools, combining different surveys with similar questions to conduct comparative research is also increasingly a daunting task. Survey designers who wish to reuse questions asked in previous surveys also need tools to find similar questions. To address these issues the CDSP (Réseau Quetelet) has developed a Social Science Question Database and Research Tools that allows users to search for questions (question texts, answer texts, variable labels) across datasets, compare results, and save them. The analysis can be extended to the roots of words or to include stop words. Information on each question include: questions text, categories of answer, location of the variable in the dataset, link to the variables before and after, instructions given to interviewers, text before and after the question, universe of the question, links to questionnaires. Users can store questions and export them (csv or xls). The question database is based on DDI (version 2) and the research module on Apache Solr.

C1: Recent Developments in the DDI Implementation Landscape II (Wed, 2011-06-01)
Chair:Arofan Gregory, Open Data Foundation

  • Metadata Management Platform for the Canadian Research Data Centre Network
    Pascal Heus (Metadata Technology North America Inc.)


    The DDI4RDC project aims at the implementation of open source solutions for the deployment of a DDI3 driven framework for the management of data and metadata across the Canada Research Data Centre Network providing secure access to microdata from Statistics Canada. This year's session will provide an progress report for the project (initiated in 2009), demo the DDI editors and repository services, and share experiences and lessons learned during development. This project is funded by the Canadian Foundation for Innovation under the umbrella of the University of Manitoba and is a collaborative effort between the Canadian RDC Network, Metadata Technology North America (US), Breckenhill (Canada), Algenta Technologies (US), and Ideas2evidence Ltd (Norway).
