What is it about computational communication science?

In this episode, Professor Mario Haim from LMU Munich breaks down what it really means for research to be robust — covering key concepts like generalizability, validity, reliability, reproducibility, and replicability. Mario explains how these ideas connect and why they matter, especially when studying opinionated communication with computational methods. He shares practical insights on common pitfalls, specific challenges in this field, and concrete steps researchers can take to strengthen their studies — from better documentation to transparent workflows and careful methodological choices. Whether you’re designing a new project or refining your research practices, this conversation offers valuable guidance for ensuring your work stands on solid ground.

In this episode of aBitOfCCS, Keonhi Son (Mannheim Centre for European Social Research) discusses her study on how women were talked about in the Weimar Republic’s parliament between 1919 and 1932. Using quantitative text analysis and semantic network methods, Keonhi examines how terms such as woman, mother, homemaker, and (female) worker were used in Reichstag debates from 1920 to 1932 — and how these meanings varied by political party, ideology, and gender of the speaker. The conversation sheds light on how early 20th-century German politics framed women’s roles and how those discourses both reflected and shaped broader social change.

In this episode, Dr. Aleksandar Tomašević from the University of Novi Sad takes us beyond text-based analysis to explore how emotions expressed in videos can be measured and understood. Aleksandar explains why studying non-verbal cues—especially facial expressions—is becoming crucial for understanding political communication online. He walks us through different methods for detecting these expressions, highlighting how machine learning and deep learning techniques enable computational analysis of emotions. Aleksandar also discusses the accuracy of machine-based emotion detection compared to human judgment and shares fascinating findings from his research on political leaders’ emotional expressions in video content. This conversation reveals how emotion analysis opens new doors in communication research.

In this episode, we’re joined by Dr. Johannes Gruber from Vrije Universiteit Amsterdam to unpack the world of language models. Johannes explains what language models really are and how they shape how we interact with information — from powering everyday chatbots like ChatGPT to supporting advanced research. We break down how these systems work behind the scenes, what they’re great at, and where we need to be cautious. Johannes also shares insights from his recent research on the feedback loops between language models, citizens’ beliefs, and democracy. It’s a closer look at why understanding both the potential and the limits of language models is so important for opinion research today.

Tune in to the #aBitOfCCS Podcast as we explore the computational workflow behind digitizing a historical society magazine. Christian Lendl joins us to discuss his paper Digitizing the Aristocratic Elite: Computational Challenges and Methods in Processing the Wiener Salonblatt (1870–1938). The episode highlights how AI-driven workflows can open new possibilities for digital humanities research.
