Capturing Developments in an Emerging Technology: an Updated Search Strategy for Identifying Nanotechnology Research Outputs

捕捉新兴技术的发展：确定纳米技术研究成果的最新搜索策略
摘要
Bibliometric analysis of publication metadata is an important tool for investigating emerging fields of technology. However, the application of field definitions to define an emerging technology is complicated by ongoing and at times rapid change in the underlying technology itself. There is limited prior work on adapting the bibliometric definitions of emerging technologies as these technologies change over time. The paper addresses this gap. We draw on the example of the modular keyword nanotechnology search strategy developed at Georgia Institute of Technology in 2006. This search approach has seen extensive use in analyzing emerging trends in nanotechnology research and innovation. Yet with the growth of the nanotechnology field, novel materials, particles, technologies, and tools have appeared. We report on the process and results of reviewing and updating this nanotechnology search strategy. By employing structured text-mining software to profile keyword terms, and by soliciting input from domain experts, we identify new nanotechnology-related keywords. We retroactively apply the revised evolutionary lexical query to 20 years of publication data and analyze the results. Our findings indicate that the updated search approach offers an incremental improvement over the original strategy in terms of recall and precision. Additionally, the updated strategy reveals the importance for nanotechnology of several emerging cited-subject categories, particularly in the biomedical sciences, suggesting a further extension of the nanotechnology knowledge domain. The implications of the work for applying bibliometric definitions to emerging technologies are discussed.
中文摘要
出版物元数据的文献计量分析是研究新兴技术领域的重要工具。然而，应用领域定义来定义新兴技术，由于基础技术本身正在发生变化，有时变化很快，因此变得复杂。由于新兴技术随着时间的推移而变化，因此在调整这些技术的文献计量学定义方面的工作有限。该文件解决了这一差距。我们借鉴了佐治亚理工学院2006年制定的模块化关键词纳米技术搜索策略。这种搜索方法已被广泛用于分析纳米技术研究和创新的新兴趋势。然而，随着纳米技术领域的发展，出现了新的材料、粒子、技术和工具。我们报告了审查和更新这一纳米技术搜索策略的过程和结果。通过使用结构化文本挖掘软件来分析关键词，并通过征求
