![]() We develop an integrative synthesis of different overlay mapping techniques and associated perspectives on technological emergence across geographical, This paper examines the use of scientometric overlay mapping as a tool of “strategic intelligence†to aid the governing of emerging technologies. Strategic intelligence on emerging technologies: Scientometric overlay mapping First, global and overlay maps were developed for the 2 We compare the network of aggregated journal–journal citation relations provided by the Journal Citation Reports (JCR) 2012 of the Science Citation Index (SCI) and Social Sciences Citation Index (SSCI) with similar data based on Scopus 2012. We first discuss the pros and cons of theĪggregated journal–journal citation relations in scopus and web of science matched and compared in terms of networks, maps, and interactive overlays Recent advances in methods and techniques enable us to develop interactive overlays to a global map of science based on aggregated citation relations among the 9162 journals contained in the Science Citation Index and Social Science Citation Index 2009. Interactive overlays: a new method for generating global journal maps from Web-of- Science data We then show how these science overlay maps help This article describes how this approach fits with other efforts to locally and globally map scientific outputs. We present a novel approach to visually locate bodies of research within the sciences, both at each moment of time and dynamically. Science overlay maps: a new tool for research policy and library management Purpose The purpose of this study is to modernize previous work on science overlay maps by updating the underlying citation matrix, generating new clusters of scientific disciplines, enhancing visualizations, and providing more accessible means for analysts to generate their own maps. Visualization of disciplinary profiles: Enhanced science overlay mapsĬarley, S. ![]() Originality/value: The routine we advance allows users to visualize science overlay maps in VOSviewer using data from more recent Journal Citation Reports. ![]() Practical implications: Visualization of science overlay maps is now more accurate and true to the 2015 Journal Citation Reports than was the case with the previous version of the routine advanced in our paper. Also, to apply the routine we provide users need access to the Web of Science. ![]() #PS4 TARGET PORT QUEZ STRESSER UPDATE#Research limitations: As Web of Science Categories change and/or are updated so is the need to update the routine we provide. In Figures 1–9 we provide basemaps of science and science overlay maps for a number of companies, universities, and technologies. Findings: Findings appear in the form of visuals throughout the manuscript. A routine for making overlays on the basis of the map (“wc15.exe†is available at. We first develop the citing-side, cosine-normalized map using 2015 data and VOSviewer visualization with default parameter values. We normalize this matrix using the cosine function. ![]() Using dedicated software, a matrix of 227 Ã- 227 cells is generated on the basis of whole-number citation counting. The set of Web of Science Categories in the Science Citation Index and the Social Sciences Citation Index increased from 224 in 2010 to 227 in 2015. Design/methodology/approach: We use the combined set of 2015 Journal Citation Reports for the Science Citation Index (n of journals = 8,778 and the Social Sciences Citation Index (n = 3,212 for a total of 11,365 journals.
