28.11.2023

We are thrilled to announce that Jana Bernhard, a member of the Computational Communication Science Lab at the University of Vienna, recently presented a thought-provoking talk at the University of Lausanne's Methods and Research Meeting. The presentation, titled "Validating Topic Modeling: Navigating Textual Data Analysis," delved into the intricacies of topic modeling, shedding light on the critical aspect of validation in the context of abundant textual data.

In an era where text analysis plays a pivotal role in research across various disciplines, Jana's presentation addressed methodological challenges and innovative approaches in validating topic models. The talk explored questions such as the goals of topic modeling in general, what we understand by topics, the topic modeling process, including a focus on model selection, and how validation methods play into this process. Attendees gained valuable insights into ensuring the validity and usefulness of the topics uncovered, ultimately answering the crucial question of whether topic modeling is a suitable method for their research projects. Jana's engaging discussion provided a platform for researchers to navigate the complexities of automated text analysis, fostering a deeper understanding of this powerful tool for uncovering latent themes and patterns within large corpora of text. Stay tuned for more updates on our team's contributions to cutting-edge research methodologies!
