How to detect Macroscopic Eventsout of Weekly Results?
1. Find homogeneous sub-periods in order to identify stable states
2. Minimize the number of periods in order to reveal significant transitions
Two measures that should be jointly optimized:1. Minimize the information loss2. Maximize complexity reduction

Outcome of spatial analysis
An inductive approach that reveals :
1.Systematic association of Syria with neighboring countries involved in the conflict (Turkey, Lebanon, Jordan, …)
2.Systematic association of Russia to Syrian conflict in all media (but not China …).
3.Variable association of USA, France, Gulf countries, according to the different media.

Outcome of network analysis
A hierarchical clustering technique that:
1.Provides macro-representations of international relations as reflected by associations in media news.
2.Reveals the dominant position of USA in the international news and the variable importance of EU.
3.Reveals the existence of local associations of countries related to geopolitical conflict or crisis (Syrian Crisis, but also Israel/Palestine, North/South Korea, …).
