Technology evolution pathways have caught researchers' interest as a powerful method to trace the historical route and forecast the future trends of NESTs. Patent citation analysis provides another means to track technological change and evolving pathways. However, gaining an understanding of technology's detailed changes from large patent citation networks is difficult to achieve because of their large and complex structures. Moreover, the neglect of some essential technologies is an unavoidable problem when we just attend to main citation networks. This paper proposes a method of observing the technology development phases and combining tech mining to capture key technological attributes with patent citation network analysis to study the technological trajectory. Dye-sensitized solar cells (DSSCs), as a promising NESTs, could lead to remarkable growth in the renewable energy industry. Therefore, we illustrate our approach with this case and engage knowledgeable experts on the topic of DSSCs to assess the resulting content. The results show that our method can be applied to identify technology evolution pathways and then help decisionmakers forecast future technology activities.

These new journals are large in number and, in their early years, it is unclear how central these journals will be in the fields of science and technology. On one hand, these new journals offer valuable data sources for bibliometric scholars to understand and analyze emerging fields; on the other hand, how to identify important peer-reviewed journals remains a challenge-and one that is essential for funders, key opinion leaders, and evaluators to overcome. To fulfill growing demand, the Web of Science platform, as the world's most trusted research publication and citation index, launched the Emerging Sources Citation Index (ESCI) in November 2015 to extend the universe of journals already included in the Science Citation Index Expanded, the Social Sciences Citation Index, and the Arts & Humanities Citation Index. This paper profiles ESCI, drawing some comparisons against these three established indexes in terms of two questions: (1) Does ESCI cover more regional journals of significant importance and provide a more balanced distribution of journals? (2) Does ESCI offer earlier visibility of emerging fields and trends through upgraded science overlay maps? The results show that the ESCI has a positive effect on research assessment and it accelerates communication in the scientific community. However, ESCI brings little impact to promoting the inferior role of non-English countries and regions. In addition, medical science, education research, social sciences, and humanities are emerging fields in recent research, reflected by the lower proportion of traditional fundamental disciplines and applied science journals & Xuefeng Wang

Capturing early events in technology development can provide key insights into the nature of biomedical innovation and its bottlenecks. The sheer volume of the available information, however, presents a significant barrier to a systematic assessment of current capabilities. Nanomedicine, which deals with medical applications of nanotechnology, perfectly exemplifies the challenges facing translational research. In this study, we have explored the feasibility of using a streamlined tech mining approach for identification of translational innovation pathways using observable markers found in research literature. The framework contains three sections: 1) extraction of feature terms from titles and abstracts; 2) tagging research articles with translational stages and application markers; and 3) analysis of topical changes, translational phases, and innovation pathways.
