Comparative Analysis of the National Scientific and Educational Systems of Sub-Saharan African Countries with the Help of Open Access Sources

摘要

On the basis of open access sources, the methodology of comparative analysis of the national scientific and educational systems was elaborated. It has been verified for example on the countries of Sub-Saharan Africa. Based on open access data matrix (Nij) with a dimension (m×n) is constructed. In which Nij represents the number of objects (Universities, Research Centers, OA repositories, OA journals, Scopus journals) of ith country, belonging ith objects type, m is the number of countries, n is the number of objects type. With the aim of clustering Sub-Saharan African countriesin terms of the degree of the development of their scientific and educational potential based on the matrix (Nij), we introduced an integral indicator in form of a vector =(Ni, ni) where Ni = is the number of non-zero elements in the ith line of matrix (Nij). Coordinate Ni shows the aggregated potential of scientific and educational system in selected set of indicators and ni is the degree of diversification of the system. Based on the calculation of the vector , we identified 7 clusters of Sub-Saharan African countries. The first two leading clusters were South Africa, Nigeria, Kenya, Tanzania, Ghana, Sudan, Ethiopia and Uganda.
