Bibliometric methodology to detect collaborative and competitive countries

Analyses by countries are in high demand, because many policy-makers and business-planners think by country. We are providing the system of citation network analysis, and we strengthen analyses by countries in this work. So, user will be able to easily extract country´s keywords and compare text-based similarity and number of international co-authors between countries. These new functions would unveil relations between countries. The purpose of this work is to establish a methodology to detect potential collaborative and competitive countries in science and technology, comparing text-based similarity and number of international co-authors. In this work, we focused on analysis about Japan as an example, and we could pick up several implicit relations which have potential to grow collaborative or competitive relations.
