Table 2 shows the Reuters stories converted to WEIS events. Event data analysis relies on a large number of events to produce meaningful patterns of interaction. The information provided by any single event is very limited; single events are also affected by erroneous reports and coding errors. However, important events trigger other interactions throughout the system. For example while Iraq's invasion of Kuwait by itself generates only a single event with WEIS code 223--military force--the invasion triggers an avalanche of additional activity throughout the international system as states and international organizations denounce, approve or comment, so the crisis is very prominent in the event record.
