Credibility is a crucial concept in communication science and received severely increased attention, again, with CCS. That is, it serves everybody as a signpost to navigate the web whilst also being scrutinized by some via (AI-driven) signals that suggest trustworthiness. Cuihua (Cindy) Shen is Professor of Communication and Co-Director of the Computational Communication Research Lab at the Department of Communication at UC Davis. In this episode, she, Emese Domahidi (Professor at TU Ilmenau) and Mario Haim (Professor at LMU Munich) talk about the concept of credibility and its particular role with mis- and disinformation. Of course, we also talk AI and what credibility is worth when a machines can generate whatever we've learnt to be trustworthy.

Ethan Zuckerman, Associate Professor of Public Policy, Communication and Information at the U of Massachusetts Amherst, is our guest, and he is on a mission to fix platforms. Not because he thinks they are inherently bad, but because there are several things about platforms that research (not least CCS) tells us are flawed. Emese Domahidi (Professor at TU Ilmenau) and Mario Haim (Professor at LMU Munich) talk with Ethan about why social media seems to be broken, what possible ways to fix it might be, how different regions of the world are approaching this challenge, and whether suing Facebook might make a difference.

In this episode, we look at the question of how digital media affects the well-being of users - a question that researchers have been debating for a long time.
From a communication science perspective, there are many questions in this field of research and new approaches to solving them using computational methods. In this episode, we look in particular at the measurement of media use and the new opportunities presented by digital data and computational methods, as well as the associated challenges. Doug A. Parry (Senior Lecturer at Stellenbosch University) is one of the leading experts in this field and an expert in innovative data formats for measuring media use. He talks to Emese Domahidi (Professor at TU Ilmenau) and Mario Haim (Professor at LMU Munich) about the topic.

Katya Ognyanova (Associate Professor at Rutgers U) is our guest and she is an expert on studying social networks. What's the societal problem with that, we hear you ask. Well, a lot of political knowledge and information and particularly mis- and disinformation spreading on the internet builds on social networking parameters such as strong and weak ties or partisanship among groups. Katya talks Emese (Professor at TU Ilmenau) and Mario (Professor at LMU Munich) through network essentials, the social aspects of (mis-)information, and the role of CCS in all of that.
-
In this episode we talk about platforms and their power. This includes the relevance of social media metrics to users, the gatekeeping function of platforms, and fragmentation trends. For these topics, our guest is the ideal expert to talk to: Subhayan Mukerjee (Assistant Professor at the National U of Singapore) is a computer scientist, mathematician and (computational) communication scholar. What's more, he also brings a global perspective on the use of news and the power of platforms, as Emese Domahidi (Professor at TU Ilmenau) and Mario Haim (Professor at LMU Munich) talk with him about the needs for adequate methodology and, maybe even more importantly, for adequate theory.

Continuing with political language online, we seek to understand the relevance and divergence of news on the internet. Sounds trivial? Well, unfortunately, it isn't: What is "contemporary" news is decided upon by many rather than a few, it contains journalistically verified messages as well as mis- and disinformation and fake news. Jo(sephine) Lukito (Assistant Professor at the U of Texas at Austin’s School of Journalism and Media) guides us, Emese Domahidi (Professor at TU Ilmenau) and Mario Haim (Professor at LMU Munich), through the exciting and "hybrid" online news environment as well as through her own research investigating particularly the malicious political language within online public spheres. Of course, CCS plays a large role in that too, as Jo is a strong advocate of computational methods and especially of multi-platform research.

It is not very hard to find dispute, also harsh dispute, online. A phenomenon also called digital contention, this raises several questions such as why are controversies more pronounced on the web? Have people turned into a rude mob in recent years or does the web help the quarrelsome to become more present? Also, what does this mean for our research, the theories and methods we apply? On that, Emese Domahidi (Professor at TU Ilmenau) and Mario Haim (Professor at LMU Munich) talk with Christian Baden (Associate Professor at the Department of Communication and Journalism and the Smart Institute at the Hebrew U of Jerusalem) who is not only interested in the topic for his own research but who is also heading the oft-mentioned EU-funded OPINION network (https://www.opinion-network.eu/) that brings together scholars working to automatically detect and extract opinions from unstructued data.

Let's put on your legal suit and join Emese Domahidi (Professor at TU Ilmenau) and Mario Haim (Professor at LMU Munich) welcoming Natali Helberger (Distinguished Professor of Law & Digital Technology, with a special focus on AI at the U of Amsterdam). We talk about the difficulties that come with regulating newly emerging technology. We also talk about all kinds of upcoming EU regulations (such as the Digital Services Act, DSA, the Digital Markets Act, DMA, and the AI Act) and the challenges of these, but also about the differences to other jurisdictional systems. Finally, we put this into perspective of CCS, talking about what will likely change in the new future for researchers (take-home message: a lot!).

In this episode, Emese Domahidi (Professor at TU Ilmenau) and Mario Haim (Professor at LMU Munich) talk to Ágnes Emőke Horvát (Assistant Professor in Communication and Computer Science at Northwestern University where she leads the Lab on Innovation, Networks, and Knowledge, LINK) about what gender biases are, their origins and how prevalent these systematic misrepresantions are. Moving to Computational Communication Science, we then discuss how gender biases (and inequalities, more generally) affect our research, our data, tools, measures, and models. And we tackle the big question how potential routes forward could look like.

How to measure racism in news media is the main question in today's episode. Ahrabhi Kathirgamalingam looks into racist and discriminative language as well as dynamics of racism in some 30 years of German-speaking news media. As that's quite a lot of data, of course Ahrabhi also builds on CCS methods. Yet, in addition to the mere amount of data, coding racism also bears big questions of validity and ethics for coders and annotators -- an issue where CCS might also be able to help. In this episode hosted by Jana Bernhard, Ahrabhi talks us through dictionaries and the many options to construct and validate dictionaries in this area. Her research is part of her PhD project about which she is happily reachable via [email protected]. Also, some results were presented at the 2023 ICA in Toronto. Oh, and if you want to guest or host a future episode, please don't hesitate reaching out to us.

Today's CCS study is about the application and particularly the development of dictionaries to apply to quantitative text analyses. Anke Stoll (together with Lena Wilms and Marc Ziegele in this publication from 2023) developed a dictionary to detect German incivility. She did so through a combination of manual and automated approaches, through classic word lists and word embeddings. Hosted by Emese Domahidi, Anke takes us through her approach, the challenges, and of course the potentials she sees with these kinds of techniques. The journal article was just published in Communication Methods and Measures. Oh, and if you want to guest or host a future episode, please don't hesitate reaching out to us.

In today's episode, Frederic R. Hopp (@Freddy_Hopp) discusses with Emese Domahidi (@MissEsi) and Mario Haim (@DrFollowMario) about morality. What's that, why does it affect our daily lifes and our social cohesion, what does it have to do with media content, and how can it be measured? CCS research offers a wide variety of tools to handle morality but also comes with quite a lot of challenges. Freddy takes us through them and discusses with us how research on morality is also affected by current societal developments.
