Researchers say analysis of social media posts can give an early warning about when and where people move in crises. This could help humanitarian agencies respond faster when surveys and field data are hard to collect.
The study appears in EPJ Data Science. The team looked at nearly 2 million posts in three languages on X. They studied three cases: Ukraine, Sudan and Venezuela. Ukraine saw 10.6 million people displaced, Sudan about 12.8 million, and Venezuela about 7 million.
Researchers found that sentiment labels (positive, negative, neutral) were more reliable than emotion labels for predicting movements. Pretrained language models gave the most useful early warning. The authors say the method works best in conflict settings and should be used with traditional data to avoid false alarms.
