新兴技术识别方法研究综述 总被引：3，自引：1，他引：2
[目的/意义] 对国内外新兴技术识别方法进行系统梳理,总结研究现状,分析存在问题,为今后新兴技术识别方法的研究提供参考。[方法/过程] 在文献调研与计量分析的基础上,归纳总结目前主流的新兴技术识别方法,结合典型案例分析各类方法的特征及其在新兴技术识别过程中的优缺点,并为未来新兴技术识别方法研究提出建议。[结果/结论] 目前的新兴技术识别方法既有定量的,也有定性的,常见的方法包括基于测度模型、文献计量以及文本挖掘的方法,且越来越倾向于多方法融合应用,不过现有研究仍然存在一些不足。未来对新兴技术识别方法的研究应该加强对新兴技术本质特征的探究,加强具体识别方法对新兴技术的解释意义,以及从数据源、识别方法两方面共同提升新兴技术识别的时效性;同时,还应该加强对新兴技术识别中多源数据有效融合与应用方法的探索。 相似文献

��[Purpose/significance] The paper systematically analyzes the identification methods of emerging technologies at home and abroad, then summarizes research status and analyzes existing problems to provide reference for future research on identification methods of emerging technologies.[Method/process] On the basis of literature research and bibliometric analysis, this paper summarized the current mainstream identification methods of emerging technologies and analyzed its characteristics and its impact on the research of identification methods of emerging technologies combined with typical cases, then proposed suggestions for future research on identification methods of emerging technologies.[Result/conclusion] The current identification methods of emerging technologies conclude quantitative methods and qualitative methods. The common identification methods of emerging technologies are mainly based on measurement models, bibliometrics and text mining methods, and they are increasingly inclined to be multi-method fusion. However, there are still some deficiencies in the research. Future research on identification methods of emerging technologies should strengthen the exploration of the essential characteristics of emerging technologies, and strengthen the interpretation of specific identification methods to emerging technologies, and promote the timeliness of identification of emerging technologies from data sources and identification methods as well as Strengthen the exploration of effective fusion methods and application methods of multi-source data in the identification of emerging technologies. 相似文献

领域前沿识别方法综述 总被引：1，自引：0，他引：1
[目的/意义]通过比较分析不同的领域前沿识别方法,总结各类方法在识别与预测前沿上的优缺点,为未来研究前沿的识别与预测提出改进意见。[方法/过程]通过综述国内外研究前沿相关的文献,辨析研究前沿的相关概念。分析目前主要的研究前沿识别方法,相较于传统的识别方法,重点对变革性研究前沿的识别方法进行归纳。总结当前领域前沿识别方法存在的主要问题,并提出改进建议。[结果/结论]就概念而言,对“研究热点”、“新兴研究”和“研究前沿”的概念内涵在时间和创新程度两个维度上进行了区分,依据创新程度的不同,研究前沿可以分为“常规性研究前沿”和“变革性研究前沿”;就识别方法而言,不同方法都有其适用场景。未来需要深入挖掘“研究前沿”,尤其要关注到主题之间的语义关联和多源数据的多元关系融合,以及对“变革性研究前沿”的前期征兆进行特征挖掘,并构建相应的识别与预测方法。 相似文献

学术期刊影响力评价方法研究进展 总被引：1，自引：0，他引：1
[目的/意义]期刊影响力评价是科学计量学研究的重要组成部分和应用领域,对于优化期刊质量、促进科学交流具有重要意义。[方法/过程]综述国内外期刊影响力评价方法研究进展,从传统指标、影响因子系列评价指标、H指数以及衍生指标、类PageRank及其衍生指标、基于多因素综合评价方法、基于社交媒体的期刊影响力评价指标以及跨学科期刊评价方法出发,总结现有学术期刊影响力评价方法的特征及其不足之处。[结果/结论]现有评价指标融合度较差,较少考虑引文偏态与自引问题,且新兴的基于社交媒体的评价方法可行性有待商榷。未来应重视深度融合评价指标,引文偏态改进方法多样化,社交媒体期刊评价方法规范化以及跨领域期刊评价方法体系化。 相似文献

Monte Carlo simulation is a useful but underutilized method of constructing confidence intervals for indirect effects in mediation analysis. The Monte Carlo confidence interval method has several distinct advantages over rival methods. Its performance is comparable to other widely accepted methods of interval construction, it can be used when only summary data are available, it can be used in situations where rival methods (e.g., bootstrapping and distribution of the product methods) are difficult or impossible, and it is not as computer-intensive as some other methods. In this study we discuss Monte Carlo confidence intervals for indirect effects, report the results of a simulation study comparing their performance to that of competing methods, demonstrate the method in applied examples, and discuss several software options for implementation in applied settings. 相似文献

This article chronicles the rapid expansion since 1990 of research within archival science and characterizes contemporary
archival research culture. It examines the role and state of key factors that have led to the development of the existing
research infrastructure, such as growth in doctoral education, forums for presenting and publishing research, the numbers
and size of graduate archival education programs, availability of diverse funding for research, transdisciplinary and international
research collaborations, and application of innovative research methods and tools appropriate for investigating increasingly
complex and wide-ranging research questions. An Appendix articulates and names archival research methods, including those
derived and adapted from other disciplines, with a view to adding to the “literary warrant” for archival research methods,
promoting the rigorous application of research design and methods, and providing sources for the teaching of research methods
for professional and research careers. The article concludes with recommendations about how to sustain and extend the emerging
research front. 相似文献

We evaluate five term scoring methods for automatic term extraction on four different types of text collections: personal document collections, news articles, scientific articles and medical discharge summaries. Each collection has its own use case: author profiling, boolean query term suggestion, personalized query suggestion and patient query expansion. The methods for term scoring that have been proposed in the literature were designed with a specific goal in mind. However, it is as yet unclear how these methods perform on collections with characteristics different than what they were designed for, and which method is the most suitable for a given (new) collection. In a series of experiments, we evaluate, compare and analyse the output of six term scoring methods for the collections at hand. We found that the most important factors in the success of a term scoring method are the size of the collection and the importance of multi-word terms in the domain. Larger collections lead to better terms; all methods are hindered by small collection sizes (below 1000 words). The most flexible method for the extraction of single-word and multi-word terms is pointwise Kullback–Leibler divergence for informativeness and phraseness. Overall, we have shown that extracting relevant terms using unsupervised term scoring methods is possible in diverse use cases, and that the methods are applicable in more contexts than their original design purpose. 相似文献

大数据时代,知识资源呈现数量大、种类多、关系复杂等特征,增加了知识组织的难度,仅依靠知识自组织方法或知识他组织方法很难缓解这一困境。针对这一问题,文章尝试融合知识自组织和他组织方法。首先,对知识自组织和他组织方法进行简要介绍,其次,从知识组织的主客体、理念、维度、工具、方法与技术等方面比较知识自组织与他组织方法,挖掘两者的融合点。最后,探讨知识自组织和他组织方法融合机理,并构建知识自组织和他组织方法融合模型。本研究不仅深化了知识组织理论,还为知识组织实践工作提供新的方法,具有重要意义。 相似文献

Methodological transparency facilitates rigorous, trustworthy, and reliable mixed methods research (MMR). Because divergent views on the conceptualization of mixed methods can create confusion for researchers, methodological transparency can help researchers to replicate methods in other studies and attract them to mixed methods research. Many studies have been conducted to assess the utilization of mixed methods research in several disciplines, but few in library and information science (LIS) have studied how authors describe the methods used. This study investigated the clarity and detail provided about methodology in mixed methods research articles in LIS, focusing on South Africa and Nigeria. Content analysis was used to assess 104 doctoral theses, of which 10 used mixed methods. Results suggest that methodological transparency in MMR research is underrepresented in LIS. This study contributes to the discussion on how LIS can enhance the quality of mixed methods research studies by underscoring the importance of methodological transparency in such studies. Researchers and LIS educators can use the gaps identified by this study to use and report mixed methods appropriately in future research. 相似文献
