MLLMs for Video Analysis: Input Representation Matters for Social Science Research

By PulseAugur Editorial · [1 sources] ·

A new study published on Hugging Face explores the effectiveness of multimodal large language models (MLLMs) for social science research involving video analysis. The research, which tested six open-weight MLLMs across three human-annotated video datasets, found that the choice of input representation (text, audio, video, or combined) significantly impacts measurement and analysis outcomes. Notably, no single representation consistently outperformed others, and combining inputs rarely improved performance, suggesting that input representation must be validated for both the specific construct and the estimation task.

IMPACT This research highlights the critical need for careful validation of input data when using MLLMs for social science video analysis, impacting how researchers deploy and interpret these tools.

    What Does the Model See? Representation Validity in Multimodal LLM-Based Video Analysis

    Multimodal large language models (MLLMs) allow social scientists to analyze video at scale, but researchers must decide which parts of a video to provide as input. We use the term representation validity to examine how text, audio, video, and combined inputs affect measurement an…
