CognitiveSky: Scalable Sentiment and Narrative Analysis for Decentralized Social Media

The emergence of decentralized social media platforms presents new opportunities and challenges for real-time analysis of public discourse. This study introduces CognitiveSky, an open-source and scalable framework designed for sentiment, emotion, and narrative analysis on Bluesky, a federated Twitter or X.com alternative. By ingesting data through Bluesky's Application Programming Interface (API), CognitiveSky applies transformer-based models to annotate large-scale user-generated content and produces structured and analyzable outputs. These summaries drive a dynamic dashboard that visualizes evolving patterns in emotion, activity, and conversation topics. Built entirely on free-tier infrastructure, CognitiveSky achieves both low operational cost and high accessibility. While demonstrated here for monitoring mental health discourse, its modular design enables applications across domains such as disinformation detection, crisis response, and civic sentiment analysis. By bridging large language models with decentralized networks, CognitiveSky offers a transparent, extensible tool for computational social science in an era of shifting digital ecosystems.


Bridging the Gap: A Framework for Real-World Video Deepfake Detection via Social Network Compression Emulation

The growing presence of AI-generated videos on social networks poses new challenges for deepfake detection, as detectors trained under controlled conditions often fail to generalize to real-world scenarios. A key factor behind this gap is the aggressive, proprietary compression applied by platforms like YouTube and Facebook, which launder low-level forensic cues. However, replicating these transformations at scale is difficult due to API limitations and data-sharing constraints. For these reasons, we propose a first framework that emulates the video sharing pipelines of social networks by estimating compression and resizing parameters from a small set of uploaded videos. These parameters enable a local emulator capable of reproducing platform-specific artifacts on large datasets without direct API access. Experiments on FaceForensics++ videos shared via social networks demonstrate that our emulated data closely matches the degradation patterns of real uploads. Furthermore, detectors fine-tuned on emulated videos achieve comparable performance to those trained on actual shared media. Our approach offers a scalable and practical solution for bridging the gap between lab-based training and real-world deployment of deepfake detectors, particularly in the underexplored domain of compressed video content.


Cancel Culture Comes for Artists Who Posted About Charlie Kirk's Death

WIRED

Cancel Culture Comes for Artists Who Posted About Charlie Kirk's Death A episode was taken off air, a DC comic series was canceled, and several artists were fired in the aftermath of the shooting. Almost immediately after she posted about the shooting of Charlie Kirk, author and transwoman Gretchen Felker-Martin started having second thoughts. Felker-Martin, who wrote the latest iteration of DC Comics' series, said "thoughts and prayers you Nazi bitch" on Bluesky in response to the killing of Kirk, a right-wing influencer and Trump ally who was staunchly anti-trans rights. "Hope the bullet's okay after touching Kirk," she added. Kirk died after being shot at a stop on his American Comeback Tour organized by the conservative youth organization he founded, Turning Point USA.
