Publications

Below is a short list of my selected publications on research topics I focused in the recent years, more specifically on (1) Privacy Preserving Information Retrieval (Textual and Visual information), (2) Efficient Data Mining and (3) Social network Construction Methods as well as on (4) Gamification in Crowdsourcing. For some main research works demonstration papers were also published. The whole list of currently around 40 publications, available at DBLP and Google Scholar included research on Semantic Web, Social Media, Topic Modelling, Machine Learning and Visual Analytics, Privacy Preserving P2P, Citizen Science and Collaborative Research Infrastructures (E-Learning and Social Sciences). The most complete publication list is available at my Bibsonomy profile.
