Tuesday 17 April 2018 – Lunchtime Seminar with Professor Dr Robert Jäschke (Humboldt University, Berlin)

Speaker: Professor Dr Robert Jäschke (Humboldt University, Berlin)

Title: Analysing the Activity of Computer Scientists on Twitter

Date and time: Tuesday 17 April 2018, 1PM-2PM

Hosted by: Professor Simon Andrews


For millions of users Twitter is an important communication platform, a social network, and a system for resource sharing. Likewise, researchers use Twitter to connect with other researchers, announce calls for papers, or share their thoughts. Filtering tweets, discovering other researchers, or finding relevant information on a topic of interest, however, is difficult since no directory of Twitter users with an academic background exists.

In this talk an approach to identify Twitter accounts of researchers is presented and its utility for the discipline of computer science is demonstrated. Next to basic properties like the age, popularity, influence, and temporal activity of the users the talk also presents an analysis of the reciprocal interaction between PhD students and professors and of content that is frequently shared among researchers.



Robert Jäschke is Professor of Information Processing and Analytics at the Humboldt-Universität zu Berlin, Germany. He received a M.Sc. degree in Mathematics from the Technische Universität Dresden, Germany, in 2005 and a PhD in Computer Science from the Universität Kassel, Germany, in 2010. His research area is web science, an emerging branch of data science that is dedicated to the study of the World Wide Web. As a web scientist he aims at a better comprehension of the web as a socio-technical phenomenon in order to contribute to our understanding of human behaviour. Specifically, Robert’s work is centred around the analysis and design of algorithms and web-based information systems that support researchers in their work. For that purpose, he is developing and leveraging methods from information extraction and retrieval, machine learning, knowledge discovery, and social network analysis.

Robert has extensive expertise in the benchmarking of algorithms, specifically in the area of recommender systems. He was co-organiser of three ECML PKDD Discovery Challenges (2009, 2009, and 2013) which enabled researchers to compare their algorithms in a competition. Robert is co-founder and leader of the social bookmarking system BibSonomy and member of L3S Research Center, Hannover, Germany.
