Bolivian roadblocks predicted by new hybrid NLP and time series model

Researchers have developed a hybrid probabilistic forecasting system to predict roadblocks in Bolivia, which cause significant economic losses. This system integrates time series decomposition using Prophet with natural language processing (NLP) applied to news articles. The NLP component uses semantic embeddings and zero-shot classification to detect early signs of escalating social tensions. The hybrid model demonstrated superior performance compared to statistical benchmarks like SARIMA and LightGBM, achieving a higher AUC-ROC and reducing the Brier Score, indicating its effectiveness in risk management for transport corridors.
