technologies 2 » technologies _, technologies 4
developing ai » developing a, developing av, developing asia
3 developing » 3 development
ai africa » ii africa, can africa, 1 africa
costs 3 » costs _, costs 4, costs a
1 eu » _ eu, i eu, 1 zu

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies 2 information ((1 eu) OR (1 e)) de communication costs 3 developing ai africa.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information ((1 eu) OR (1 e)) de communication costs 3 developing ai africa.*.
