Query: Multi-cultural Wikipedia mining of geopolitics interactions leveraging
  reduced Google matrix analysis   Geopolitics focuses on political power in relation to geographic space.
Interactions among world countries have been widely studied at various scales,
observing economic exchanges, world history or international politics among
others. This work exhibits the potential of Wikipedia mining for such studies.
Indeed, Wikipedia stores valuable fine-grained dependencies among countries by
linking webpages together for diverse types of interactions (not only related
to economical, political or historical facts). We mine herein the Wikipedia
networks of several language editions using the recently proposed method of
reduced Google matrix analysis. This approach allows to establish direct and
hidden links between a subset of nodes that belong to a much larger directed
network. Our study concentrates on 40 major countries chosen worldwide. Our aim
is to offer a multicultural perspective on their interactions by comparing
networks extracted from five different Wikipedia language editions, emphasizing
English, Russian and Arabic ones. We demonstrate that this approach allows to
recover meaningful direct and hidden links among the 40 countries of interest.
