LLM Accuracy for Policy Filtering and Policy Instrument Classification. The graph illustrates the accuracy in two tasks: policy filtering based on climate change mitigation/adaptation effects and policy instrument classification (CCI, MXI, VOI). The left-hand side of the graph represents the accuracy metrics using binary-average method for policy filtering, while the right-hand side displays the accuracy metrics using weighted-average method for policy instrument classification. The different metrics represented by the different types of line. For policy filtering, binary-averaged precision, recall, and F1-score were used. For policy instrument classification, weighted-averaged precision, recall, and F1-score were applied.
