Simultaneous mapping of interactions between S&T knowledge bases: The case of space communications

This paper examines the knowledge structure of the field of space communications using bibliometric mapping techniques based on textual analysis. A new approach with the aiming of visualizing simultaneously the configuration of its scientific and technological knowledge bases is presented. The bibliometric map revealed weak cognitive interactions between science and technology at the worldwide level although it brings out the systemic nature of the process of knowledge production at either side. We extended the mapping approach to the research activities of the Triad countries in order to characterize their specialization profiles and cognitive links on both sides in comparison with the structure of the field at the worldwide level. Results showed different patterns in the way the Triad countries organized their scientific and technological research activities within the field.
