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，应用字段定义来定义新兴技术由于基础技术本身的持续且有时快速的变化而变得复杂。由于新兴技术随着时间的推移而发生变化，因此在调整新兴技术的文献计量学定义方面的工作有限。本文件解决了这一差距。我们借鉴的例子，模块化的关键字纳米技术的搜索策略，在格鲁吉亚理工学院在2006年。这种搜索方法在分析纳米技术研究和创新的新兴趋势中得到了广泛的应用。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。我们报告的过程和结果的审查和更新这一纳米技术的搜索策略。通过采用结构化的文本挖掘软件来分析关键词术语，并通过征求领域专家的意见，我们确定了新的纳米技术相关的关键词。我们追溯适用于20年的出版物数据和分析结果的修订进化词汇查询。我们的研究结果表明，更新的搜索方法提供了一个渐进的改进，在召回率和精度方面的原始策略。此外，更新的战略揭示了纳米技术的几个新兴的引用主题类别的重要性，特别是在生物医学科学，这表明纳米技术知识领域的进一步扩展。将文献计量学定义应用于新兴技术的工作的影响进行了讨论。
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.
