Projects / Research Interests

  • Sentiment Analysis

I have been working on a Sentiment Analysis project which our department has carried out in cooperation with ARGUS der Presse (nowadays ARGUS DATA INSIGHTS), a media monitoring company. 

  • Computer-Based Media Content Analysis | Framing

In October 2013, I started my PhD about Computer-Based Media Content Analysis which is only one project among ten other groups with their projects in the NCCR democracy research program (3rd phase). This research program focuses on the challenges to democracy in the 21st century and traces them to two major trends: globalization and the growing influence of the media on politics.

The main goal will be to provide access to enriched media data (using Named Entity Recognition, Text Mining, Sentiment Analysis, Relation Mining und several Corpus Linguistics methods) to the other projects and to make the next steps towards a fully automated media content analysis.

Furthermore, we will implement an approach which will be based on data-driven, inductive framing analysis. In this special case we are going to explore further semantically oriented methods coming from the realm of computational linguistics. Especially the coupling of (structured) topic modeling and target-specific, aspect-based sentiment analyis is used to make the shifts in topic and tonality visible. A more profound and updated description of the project and its role and integration in the entire NCCR democracy phase III can be found here on the NCCR democracy website.

Results from an experiment reproducing manual annotation on a large scale corpus can be found here. We used an paragraph-based modeling approach relying on embedded sentences in combination with quantized centroid similarity which allowed for inclusion of knowledge-based lexical resources while still providing the robustness of data-driven methods.
