Knowledge map of publications in research policy

Research Policy as a leading journal among others in the fields of social science, plays as an important platform for policy researchers to have their research results published, documented and shared internationally. This study uses Research Policy as a window or an indicator to understand overview of global Sci-Tech and Innovation Policy/Management researches, as well as unveil how papers in Research Policy are correlated to each other and how quantitative technology management can be possibly obtained. This study positions research foci in Research Policy by keyword-based network analysis. A keyword-based network which is also named as "research focus parallelship network" can be visually obtained and network properties, e.g. degree centrality, betweenness centrality, closeness centrality, can be calculated. The keyword-based network can be depicted differently to reflect its research focus parallelship as well as knowledge linkage implication by choosing different information as network actors such as keyword, first author, institute, or country. Totally 2014 keywords contained in 934 papers published in Research Policy in the period of 1998-2008.
