Working with reliable data, metrics, and methods, as well as valid theories, is essential for advancing the computational humanities and social sciences. In this talk, I present our research on the following question:
1.) How do limitations related to the provenance and quality of digital social data impact research results? I present on the impact of commonly used techniques for name disambiguation on the properties and dynamics of social networks, highlight measurement-induced biases in metrics and theories, and address means for mitigating these limitations.
2.) How can we combine methods from natural language processing and network analysis to jointly consider the content and structure of social relations? I provide an example where we applied domain-adjusted text mining to enhance social networks to validate a classic social science theory in a contemporary setting.
3.) How can we assess the impact of information and science on people and society beyond using bibliometric methods? I present our work on predicting the impact of media on individual behavior, cognition, and emotions, and measuring the long-term impact of scientific research on society.
4.) When working with human-centered and online data, how can we comply with data governance regulations while still do innovative work? I discuss challenges and opportunities for using digital social data in responsible and practical ways.
Overall, the work presented in this talk contributes to making sense of qualitative, distributed, and multi-modal data in a scalable way; and advancing the transparency, responsibility, and ethics of computing and technology as applied to trying to better understand society.
Die Keynote wird in Deutsch gehalten.
Jana Diesner is an Associate Professor at the School of Information Sciences at the University of Illinois at Urbana-Champaign. Diesner's research in social computing and human-centered data science combines methods from natural language processing, social network analysis, and machine learning with theories from the social sciences, humanities, and
linguistics to advance knowledge and discovery about interaction-based and information-based systems. Her lab is currently working on projects related to:
1.) biases in data, technology and human decision making,
2.) data governance,
3.) validating social science theories in contemporary
4.) impact assessment,
5.) crisis informatics.
Recent recognition for her research expertise includes a Linowes Fellowship from the Cline Center for Advanced Social Research at Illinois (2018), a R.C. Evans Data Analytics Fellowship from the Deloitte Foundation Center for Business Analytics at UIUC (2018), and an appointment as the CIO Scholar for Information Research & Technology at Illinois (2018).
Diesner has published more than 55 referred articles. She got her PhD (2012) from the School of Computer Science at Carnegie Mellon University.
