The conversationality index

What is it about?

Social media can help people feel socially connected, but it has also been linked to loneliness and poorer wellbeing. One reason for these mixed findings may be that many online interactions appear social without involving the sustained exchanges that characterize genuine conversations. We introduce the Conversationality Index, a measure that quantifies how closely online discussions resemble real-world conversations. Applying it to thousands of YouTube comment threads in English and German, we show that it distinguishes between isolated comments and sustained, balanced exchanges. The index provides a new tool for measuring conversationality in large-scale online discussions in real time and could support future efforts to identify potentially harmful interactions or encourage healthier patterns of online communication.

Why is it important?

Online interactions are often treated as conversations, yet there has been no straightforward way to measure how closely they resemble genuine conversational exchanges. We introduce a language-independent Conversationality Index that distinguishes between isolated comments and sustained, balanced discussions. Because it relies on the structure of interactions rather than their content, the measure can be applied across languages, topics, and online platforms, and at large scale. This creates new opportunities to study online communication, community formation, and the role of conversational interactions in digital environments.
