“…Such analyses may also lead to insights on the directions and paths of technology diversification of an innovation agent, e.g., firm, city or country (Breschi et al, 2003;Rigby, 2013;Boschma et al, 2014), or help forecast development directions and potentials of an emerging technology, e.g., fuel cells or solar cells (Kajikawa et al, 2008;Ogawa and Kajikawa, 2015;Benson and Magee, 2013;, given the locations of its established knowledge base in the technology space. In general, such a map of technology fields will be useful to aid in technology road mapping of innovation agents or technology-based industries and forecasting development directions of emerging technologies.…”

Recent works in the information science literature have presented cases of using patent databases and patent classification information to construct network maps of technology fields, which aim to aid in competitive intelligence analysis and innovation decision making.Constructing such a patent network requires a proper measure of the distance between different classes of patents in the patent classification systems. Despite the existence of various distance measures in the literature, it is unclear how to consistently assess and compare them, and which ones to select for constructing patent technology network maps.This ambiguity has limited the development and applications of such technology maps.Herein, we propose to compare alternative distance measures and identify the superior ones by analyzing the differences and similarities in the structural properties of resulting patent

“…In terms of energy publications listed under the 87 energy and fuels journals we used, Kajikawa, Yoshikawa, Takeda, and Matsushima (2008) followed a similar approach in their study. For astronomy there is a relative consensus that the 60 publications in the Web of Knowledge listed under astronomy and astrophysics are representative of the core literature in this field.…”

A scientometric analysis of selected research priority areas in South Africa was done using the Web of Science database for a period 2002 -2012. The performance of the country in the areas of biotechnology, energy, astronomy and palaeontology in terms of the publication output in these areas is compared using two classic scientometric indicators, the activity and attractivity indices. These are important priority areas as highlighted in various government policy documents and the aim was to identify if outputs in these field are corresponding with government policy. The study also identifies leading institutions in the country in terms of publication output while the performance is also benchmarked against that of the other BRIC (Brazil, Russia, India and China) group of countries as well as Egypt.It is found that the country is doing relatively well in research areas in which it enjoys geographical advantage such as astronomy and palaeontology and compares favourably with comparator countries in all areas reviewed. In terms of the institutional profile and based on publication outputs over the period considered, the University of Cape Town is a leader in biotechnology and energy, University of the Witwatersrand in palaeontology and the National Research Foundation in the area of astronomy.

“…For example, using citation network data, publications can automatically be classified into several clusters that cover a specific research topic [11][12][13]. The clusters contain information such as publication number, average publication year, and the distribution of affiliations that conducted research by country, which are useful for determining whether a topic in a cluster is emerging or not, and helps with evaluating the strength of a country in a particular research area [14].…”

Abstract:Water electrolysis for hydrogen production has received increasing attention, especially for accumulating renewable energy. Here, we comprehensively reviewed all water electrolysis research areas through computational analysis, using a citation network to objectively detect emerging technologies and provide interdisciplinary data for forecasting trends. The results show that all research areas increase their publication counts per year, and the following two areas are particularly increasing in terms of number of publications: "microbial electrolysis" and "catalysts in an alkaline water electrolyzer (AWE) and in a polymer electrolyte membrane water electrolyzer (PEME).". Other research areas, such as AWE and PEME systems, solid oxide electrolysis, and the whole renewable energy system, have recently received several review papers, although papers that focus on specific technologies and are cited frequently have not been published within the citation network. This indicates that these areas receive attention, but there are no novel technologies that are the center of the citation network. Emerging technologies detected within these research areas are presented in this review. Furthermore, a comparison with fuel cell research is conducted because water electrolysis is the reverse reaction to fuel cells, and similar technologies are employed in both areas. Technologies that are not transferred between fuel cells and water electrolysis are introduced, and future water electrolysis trends are discussed.
