요약	Power transition analysis examines when and why war breaks out between a dominant state and a rising challenger as their relative power converges. Originating in A. F. K. Organski and Jacek Kugler's The War Ledger (1980), it holds that the international system is hierarchical and most dangerous not at moments of clear preponderance but when a dissatisfied rising power approaches parity with the dominant state — and it operationalizes this by tracking relative national capabilities over time and relating overtaking to the onset of major war.	Event data analysis is the automated extraction of structured records of political interactions — who did what to whom, when, and where — from large volumes of news text, for the quantitative study of conflict and cooperation. Pioneered for machine coding by Philip Schrodt with the KEDS and TABARI systems and scaled in projects such as ICEWS and GDELT, it turns unstructured reporting into dated actor-action-target triples coded to an ontology like CAMEO, which can then be aggregated into time series of interstate or intrastate hostility.
