Semi-automated analysis, aggregation, and visualization of user comments


The Forum 4.0 project builds on previous work of the SCAN-4J project with social scientists and strives for an informatics centered and interdisciplinary research partnership. The duration of the project is for three years (2018 – 2020).

Project Summary

Online user comments, such as journalistic content or product features are associated with low quality, Hate speech or even excessive demands for moderation. Forum 4.0 will develop new methods based on text analysis, machine learning (with human-in-the-loop) and Empirical Software Engineering to better exploit the constructive and deliberative potential of user comments. The aim is to systematically analyze, aggregate and visualize the content and quality of comments at runtime in order to enable constructive participation. The project builds on our previous work with social scientists and aims for an informatics-centered, interdisciplinary research network that combines the focal points “Information Governance Technologies” and “Data Science” of We foresee immense transfer potential for the media location of Hamburg.
