概要	Content analysis of treaties is the systematic, rule-governed coding of the text and design features of international agreements — their obligations, precision, delegation, enforcement, flexibility, and substantive provisions — to study how treaties are written and what explains variation in their design. It applies the established content-analysis methodology codified by Krippendorff to the specialized vocabulary of international law and institutions, often organized around frameworks such as the legalization concept of Abbott and colleagues (2000).	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.
