New DoTA metrics improve evaluation of social media topic models

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced Document-Topic Alignment metrics (DoTA), a new framework for evaluating topic models used in analyzing public health communications on social media. Unlike existing metrics that focus solely on topic generation, DoTA quantitatively assesses the semantic alignment between individual short-text posts and their assigned topics. The framework includes variants that measure assignment confidence and distinguishability, and has been shown to provide complementary evaluation cues that align with human judgment, leading to a more comprehensive assessment of topic modeling performance.

    Document Topic Alignment Metrics for Evaluating Topic Models of Short-Text Public Health Communications on Social Media

    arXiv:2609.14256v1 Announce Type: new Abstract: Topic models are widely used to analyze public health-related social media short texts, yet their evaluation remains dominated by metrics that focus entirely on generated topics alone. There is a lack of metrics that quantitatively …
