Overlapping Community Detection for Botnet analysis on Twitter

April 8th, 2022 | by

The study of (social) structures in real-world networks is known as (social) network analysis. Nodes and linkages make up networks. Communities are subnetworks in which nodes have more connections to nodes within the subnetwork than to nodes outside the subnetwork. The difficulty of detecting nodes in networks that belong to more than one sub-network is known as overlapping community detection. The goal of this work is to extend our existing bot detection framework to include community detection functionality.

Time-series based Academic Trend and Downtrend Detection

April 8th, 2022 | by

Analysis of literature in scientific conferences and journals to identify and describe the evolution of trends is valuable for supporting the dissemination and distribution of knowledge in a large-scale decentralized research community. A trend is an increase in popularity, while a downtrend describes a decrease in popularity of a certain topic. The goal of this work is to extend our existing citation recommendation bot to provide temporal context information to the recommendations by time-series based trend analysis.

Web Frontend for the Gamification of Habit Forming in Distance Education

March 31st, 2022 | by

The implementation of game-design features and gaming concepts in non-game environments is known as gamification, whereas habit development is the process through which a behavior becomes automatic or habitual via repeated repetition. The goal of this thesis is to use the open-source Gamification Framework developed at our chair in the context of seminar papers and theses. This work is intended to extend our motivation solution and build a Web frontend to provide long-term support to the learners in their academic endeavors.
