Measuring Dimensions of Self-Presentation in Twitter Bios and their Links to Misinformation Sharing

2023-05-16 · Navid Madani, Rabiraj Bandyopadhyay, Briony Swire-Thompson, Michael Miller Yoder, Kenneth Joseph

Social media platforms provide users with a profile description field, commonly known as a ``bio," where they can present themselves to the world. A growing literature shows that text in these bios can improve our understanding of online self-presentation and behavior, but existing work relies exclusively on keyword-based approaches to do so. We here propose and evaluate a suite of \hl{simple, effective, and theoretically motivated} approaches to embed bios in spaces that capture salient dimensions of social meaning, such as age and partisanship. We \hl{evaluate our methods on four tasks, showing that the strongest one out-performs several practical baselines.} We then show the utility of our method in helping understand associations between self-presentation and the sharing of URLs from low-quality news sites on Twitter\hl{, with a particular focus on explore the interactions between age and partisanship, and exploring the effects of self-presentations of religiosity}. Our work provides new tools to help computational social scientists make use of information in bios, and provides new insights into how misinformation sharing may be perceived on Twitter.

Self-Supervised Autoencoder Network for Robust Heart Rate Extraction from Noisy Photoplethysmogram: Applying Blind Source Separation to Biosignal Analysis

2025-04-12 · Matthew B. Webster, Dongheon Lee, Joonnyong Lee

Biosignals can be viewed as mixtures measuring particular physiological events, and blind source separation (BSS) aims to extract underlying source signals from mixtures. This paper proposes a self-supervised multi-encod…

Knowledge-guided EEG Representation Learning

2024-02-15 · Aditya Kommineni, Kleanthis Avramidis, Richard Leahy, Shrikanth Narayanan

Self-supervised learning has produced impressive results in multimedia domains of audio, vision and speech. This paradigm is equally, if not more, relevant for the domain of biosignals, owing to the scarcity of labelled …

Subject-Aware Contrastive Learning for Biosignals

2020-06-30 · Joseph Y. Cheng, Hanlin Goh, Kaan Dogrusoz, Oncel Tuzel 외

Datasets for biosignals, such as electroencephalogram (EEG) and electrocardiogram (ECG), often have noisy labels and have limited number of subjects (<100). To handle these challenges, we propose a self-supervised approa…

The Spread of Propaganda by Coordinated Communities on Social Media

2021-09-27 · Kristina Hristakieva, Stefano Cresci, Giovanni Da San Martino, Mauro Conti 외

Large-scale manipulations on social media have two important characteristics: (i) use of propaganda to influence others, and (ii) adoption of coordinated behavior to spread it and to amplify its impact. Despite the conne…
