Vita

Katrin Weller is postdoctoral researcher at GESIS since January 2013. Since August 2015 she is leading the team "Social Analytics and Services" in the Computational Social Science Department.
From January to June 2015 Katrin stayed at the Library of Congress in Washington, D.C., on a Digital Studies Fellowship by the John W. Kluge Center.
From 2006-2012 she was researcher and lecturer at the Department of Information Science, Heinrich-Heine-University Düsseldorf. She received her PhD in Information Science in May 2010 for her dissertation “Knowledge Representation in the Social Semantic Web”. Katrin completed a Magistra Artium degree in History, Media Studies and Information Science in 2005. She has organised several scientific workshops and conferences and is frequently serving in programme committees for international conferences and journals. She has regularly taught courses in Information Science since 2006, covering topics such as knowledge representation and document indexing, ontology engineering, information retrieval and informetrics.

Service

The team "Social Analytics and Services" is developing a new service portfolio. First services focus on Social web data for social science research and currently include:
  • support for studies that use social media data
  • workshops
  • international presentations
  • reviews
Please do not hesitate to get in touch with any practical questions concerning social media data usage in social science research or with questions and comments on the role of new data sources for social science research.

Research

Research interests include but are not limited to:
  • "The Hidden Data of Social Media Research"
  • interdisciplinary social media research methods (including standards and research ethics)
  • social media in academia and scholarly communication / science 2.0 and altmetrics
  • Twitter analytics
  • big data in the social sciences
