About

Marten Risius is an Assistant Professor in the Department of Management at Clemson University. He graduated with highest distinction in psychology from the University of Osnabrueck, Germany and was the first psychologist to graduate from the House of Finance at the Goethe University Frankfurt, where he received his PhD with highest distinction. Afterwards, he worked as postdoctorate at the University of Mannheim, Germany, where he managed the research alliance "ForDigital" between the University of Mannheim and the Karlsruhe Institute of Technology (KIT). 

His dissertation thesis was recognized as the best publication in the entire field of Business Administration from a young researcher in Germany, Austria and Switzerland by the VHB (German Academic Association for Business Research) and received the TARGION award for the best practice-oriented research on strategic information management.

His research interests are in the areas of digitalization, social media management and social media analytics with a focus on enterprise social media. His articles have been published in several conference proceedings and journals such as Journal of Strategic Information Systems (JSIS), Journal of Information Technology (JIT), Information & Management (I&M), the International Conference of Information Systems, the European Conference on Information Systems, the Hawaii International Conference on System Sciences, and the Americas Conference on Information Systems. 

He served as Associate Editor at the International Conference on Information Systems (ICIS), as Session Chair at the Pacific Asian Conference of Information Systems, and as reviewer for various international journals and conferences. In his free time he serves as member of the young jury for the DVPT Start-Up Future Award.


Differentiated Sentiment Analysis

Practitioners and researchers alike increasingly use social media messages as an additional source of information e.g., to analyze stock price movements, assess online reputation, or predict election results. So far, however, the majority of research has ignored the more complex, multi-dimensional structure of human emotions and only considered aggregated sentiment measures or made binary distinctions between positive and negative sentiment. Therefore, based on the model of the hierarchical structure of the affective domain (Ekkekakis, 2013) and the established sentiment lexicon of SentiStrength 2 (Thelwall et al., 2012), we developed and applied an open source dictionary for the analysis of seven different emotions (affection, happiness, satisfaction, fear, anger, depression, and contempt).

The dictionary is currently being revised and will soon be available for download again
