Abstract

Ismael Rafols (personal communication) suggested to me in 2008 to use journal maps as a background for portfolio analysis and visualization. Such a tool could be used for informing science & technology policy debates. I had developed journal maps since the mid-1990s on the basis of aggregated journal-journal citations as these are yearly collected and published in the Journal Citation Reports (JCR) of the Science Citation Index and the Social Sciences Citation Index by ISI/Clarivateâ„¢. However, my focus had been on developing structural and dynamic analysis of the sciences. Portfolio analysis provides another option: the journal structure is then assumed as a baseline. In this report, I propose a tool that automates the visualization of portfolios.

Keywords: maps, portfolio, diversity, interdiscuplinarity
