The Chinese Academy of Engineering (CAE) has been conducting studies pertaining to Engineering Fronts for two years since 2017, with the aim of offering academic guidance and assistance in decision making. In collaboration with Clarivate Analytics, studies in Engineering Fronts rely on nine core academic divisions and “1+9” academic journals of the CAE (i.e., Engineering and nine other specialized journals). Each year, the study issues 94 identified engineering research fronts and 96 engineering development fronts in both Chinese and English. Among them, 27 key engineering research fronts and 27 key engineering development fronts are selected for detailed interpretations. The studies in Engineering Fronts combine quantitative and qualitative analyses. On the one hand, published journal papers (e.g., from the SCIE), conference papers, and global patents are taken into consideration to obtain the initial alternative fronts. On the other hand, experts are involved in the whole study process, including proposing candidate engineering fronts from their perspective and experience, researching the results from data-mining, and interpreting the key results. This report consists of two parts. The first part introduces the methodology. The second part includes a total of nine reports on the engineering research fronts and engineering development fronts in nine fields corresponding to the nine core academic divisions. 1 Part 1 Methodology Part 1 Methodology Combining both quantitative and qualitative analyses, fronts were extracted in the following two methods. In the engineering front study applied deep integration of data first method, Clarivate Analytics clustered the top 10% highly analysis and expert advice to select a total of 94 engineering cited papers of journal literatures and conference proceedings research fronts and 96 engineering development fronts in indexed in the Web of Science Core Collection based on the co- 2018.

The second fields corresponding to the nine academic divisions of the method was based on expert proposal. These two methods Chinese Academy of Engineering (CAE) is shown in Table 1. yielded 482 candidate engineering research fronts. After expert group meetings and questionnaires, approximately 10 Clarivate Analytics conducted quantitative analysis and engineering research fronts were selected from each field. obtained 702 candidate engineering research fronts based on the co-citation clustering method and 53 ThemeScape maps of 53 disciplines of nine fields. 1.1 Production of topics In addition, experts of nine fields proposed candidate engineering Clarivate Analytics matched the Web of Science Core Collection fronts based on their insights before the original dataset was journal/conference proceedings to the nine CAE academic determined and after data mining was conducted. This was done divisions, including a total of 12 882 journals and 28 626 to supplement potential gaps in the content coverage for each conference proceedings. Experts manually reviewed the field in quantitative analysis. After several rounds of expert group journal/conference proceeding mapping table for each field meetings and questionnaires, approximately 10 engineering and finalized the list by making appropriate adjustments with research fronts and 10 engineering development fronts were their domain knowledge. Additionally, Clarivate Analytics determined. Among them, three key engineering research fronts reassigned publications in 67 Multidisciplinary Sciences and three key engineering development fronts were selected for journals such as Nature and Science to their most relevant detailed interpretation. subject area. By using the information found in the cited references of each publication, it was possible, in most cases, 1 Identification of engineering research to algorithmically reassign them to a subject area. The final fronts publication dataset comprised of articles, reviews, and proceeding papers that were published in matched journals In this report, the basic materials of engineering research and conference proceedings from the above methods.

In each field, Clarivate Analytics identified publications that were in the world’s top 10% by number of citations received, Finally, after several rounds of expert group meetings and considering the publication year and Journal Subject Category questionnaire, 94 engineering research fronts were selected (JSC). Because citation rates differ for different modes of for nine fields. publication, conference proceeding papers and journal papers were treated separately.
