Detecting the emergence of new scientific collaboration links in Africa: A comparison of expected and realized collaboration intensities

作者：

Highlights：

• Link prediction is used to generate expected networks, as a baseline against which to compare actual networks.

• Deviations between predicted and realized collaboration intensities are used to assess the impact of exogenous factors to network evolution.

• Collaboration intensity with non-African countries is higher than expected, especially for countries that are scientifically more active.
