• Abstract: The use of large language models (LLMs) is becoming common in the context of political science, particularly in studies that analyse individuals use of digital media. However, while previous research has demonstrated LLMs ability at labelling tasks, the effectiveness of using LLMs to classify political content (PC) from just URLs is not yet well explored. The work presented in this article bridges this gap by evaluating whether LLMs can accurately identify PC vs. non-PC from both the article text and the URLs from five countries (France, Germany, Spain, the UK, and the US) and different languages. Using cutting-edge LLMs like GPT, Llama, Mistral, Deepseek, Qwen and Gemma, we measure model performance to assess whether URL-level analysis can be a good approximation for full-text analysis of PC, even across different linguistic and national contexts. Model outputs are compared with human-labelled articles, as well as traditional supervised machine learning techniques, to set a baseline of performance. Overall, our findings suggest the capacity of URLs to embed most of the news content, providing a vital perspective on accuracy-cost balancing. We also account for contextual limitations and suggest methodological recommendations to use LLMs within political science studies.

We find that the best prompting strategy consists of providing the LLMs with a detailed codebook, as the one provided to human coders.

  Large Language Models (LLMs) have sparked intense debate regarding the prevalence of bias in these models and its mitigation. We propose a prompt-based method for the extraction of confounding and mediating attributes which contribute to the decision process. We find that the observed disparate treatment can at least in part be attributed to confounding and mitigating attributes and model misalignment.
