SocialPulse: An Open-Source Subreddit Sensemaking Toolkit

2026-02-06

AI Summary

Existing tools for online community discourse analysis are often closed-source, functionally limited, or difficult to extend, hindering comprehensive capture of discussion dynamics around complex social issues. To address this gap, this work proposes an open-source, interactive, and extensible analytical toolkit that, for the first time, integrates topic modeling, sentiment analysis, user activity profiling, and bot detection within a unified framework. The toolkit enables fine-grained exploration of participation patterns—from high-activity to long-tail users—and diachronic discourse evolution across Reddit subreddits. It implements an end-to-end exploratory analysis workflow and demonstrates its effectiveness on large-scale Reddit datasets, significantly enhancing the transparency, flexibility, and reproducibility of online community research.

Abstract

Understanding how online communities discuss and make sense of complex social issues is a central challenge in social media research, yet existing tools for large-scale discourse analysis are often closed-source, difficult to adapt, or limited to single analytical views. We present SocialPulse, an open-source subreddit sensemaking toolkit that unifies multiple complementary analyses -- topic modeling, sentiment analysis, user activity characterization, and bot detection -- within a single interactive system. SocialPulse enables users to fluidly move between aggregate trends and fine-grained content, compare highly active and long-tail contributors, and examine temporal shifts in discourse across subreddits. The demo showcases end-to-end exploratory workflows that allow researchers and practitioners to rapidly surface themes, participation patterns, and emerging dynamics in large Reddit datasets. By offering an extensible and openly available platform, SocialPulse provides a practical and reusable foundation for transparent, reproducible sensemaking of online community discourse.
