Faster Insights: Social Media Narrative Analysis

Evidano is an AI-powered qualitative data analysis platform that ingests, codes, and visualizes social media and transcript data. A June 30, 2026 PLOS ONE paper introduces ST-TAN, a RoBERTa-based model that fuses sentiment, topic, and temporal attention to automate social media narrative analysis (PLOS ONE). On the Twitter Event Narrative Dataset (TEND, n=120, 000) ST-TAN reaches a narrative F1 of 0.87 and narrative integrity of 85.3%, outperforming baselines by about 8–11%. If qualitative teams analyze social feeds, the paper shows how joint modeling reduces failure modes such as fragmented posts, emotion-driven topic shifts, and weak temporal ordering. Below: what the model does, practical implications, and a compact six-step workflow to reproduce the approach using AI-enabled tools like Evidano.
