Abstract Purpose We aim to extend our investigations related to the Relative Intensity of Collaboration (RIC) indicator, by constructing a confidence interval for the obtained values. Design/methodology/approach We use Mantel-Haenszel statistics as applied recently by Smolinsky, Klingenberg, and Marx. Findings We obtain confidence intervals for the RIC indicator Research limitations It is not obvious that data obtained from the Web of Science (or any other database) can be considered a random sample. Practical implications We explain how to calculate confidence intervals. Bibliometric indicators are more often than not presented as precise values instead of an approximation depending on the database and the time of measurement. Our approach presents a suggestion to solve this problem. Originality/value Our approach combines the statistics of binary categorical data and bibliometric studies of collaboration.

Abstract Purpose The 5th Plenary Session of the 19th Communist Party of China (CPC) Central Committee clearly states that developing science and technology through self-reliance and self-strengthening provides the strategic underpinning for China's development. Based on this background, this paper explores a metric model for assessing national scientific research strength through collaboration on research papers. Design/methodology/approach We propose a novel metric model for assessing national scientific research strength, which sets two indicators, national scientific self-reliance (SR) and national academic contribution (CT), to reflect “self-reliance” and “self-strengthening” respectively. Taking the research papers in quantum technology as an example, this study analyzes the scientific research strength of various countries around the world, especially China in quantum technology. Findings The results show that the research of quantum technology in China has always been relatively independent with fewer international collaboration papers and located in a more marginal position in cooperation networks. China's academic contribution (CT) to global quantum technology research is increasing and has been greater than that of the United States in 2020. Combining the two indicators, CT and SR, China's research strength in the quantum field closely follows the United States, and the United States is the most powerful with high research autonomy. Research limitations This paper only reflects China's scientific research strength in quantum technology from collaboration on research papers and doesn’t consider the segmentation of quantum technology and the industrial upstream and downstream aspects, which need further study. Practical implications The model is helpful to better understand the national scientific research strength in a certain field from “self-reliance” and “self-strengthening”. Originality/value We propose a novel metric model to measure the national scientific research strength from the perspective of “self-reliance” and “self-strengthening”, which provides a solid basis for the assessment of the strength level of scientific research in countries/regions and institutions.
党的十九届五中全会明确提出,自力更生、自强不息、科技兴国是中国发展的战略支点。在此背景下,本文探讨了通过科研论文合作评估国家科研实力的度量模型。设计/方法/方法本文提出了一种新的国家科研实力评价指标模型,该模型设置了国家科学自立(SR)和国家学术贡献(CT)两个指标,分别反映“自立”和“自强”。本研究以量子技术的研究论文为例,分析了世界各国,特别是中国在量子技术方面的科研实力。研究结果表明,中国量子技术研究一直相对独立,国际合作论文较少,在合作网络中处于较为边缘的位置。中国对全球量子技术研究的学术贡献(CT)正在增加,并在2020年超过了美国。结合CT和SR这两个指标,中国在量子领域的研究实力紧跟美国,美国是最强的,研究自主性高。本文仅从科研论文合作的角度反映了中国在量子技术方面的科研实力,并没有考虑到量子技术的细分和产业上下游等方面,这需要进一步的研究。该模型有助于从“自立”和“自强”的角度更好地理解国家在某一领域的科研实力。本文从“自立”和“自强”的角度提出了衡量国家科研实力的新度量模型,为评估国家/地区和机构的科研实力水平提供了坚实的依据。

Abstract This paper reviews literature pertaining to the development of data science as a discipline, current issues with data bias and ethics, and the role that the discipline of information science may play in addressing these concerns. Information science research and researchers have much to offer for data science, owing to their background as transdisciplinary scholars who apply human-centered and social-behavioral perspectives to issues within natural science disciplines. Information science researchers have already contributed to a humanistic approach to data ethics within the literature and an emphasis on data science within information schools all but ensures that this literature will continue to grow in coming decades. This review article serves as a reference for the history, current progress, and potential future directions of data ethics research within the corpus of information science literature.
摘要本文回顾了与数据科学作为一门学科的发展、当前数据偏见和伦理问题有关的文献,以及信息科学学科在解决这些问题方面可能发挥的作用。信息科学研究和研究人员对数据科学有很多贡献,因为他们的背景是跨学科学者,将以人为中心的社会行为视角应用于自然科学学科中的问题。信息科学研究人员已经在文献中对数据伦理的人文方法做出了贡献,并在信息学院中强调数据科学,这几乎确保了这些文献在未来几十年内继续发展。这篇综述文章为信息科学文献语料库中数据伦理研究的历史、当前进展和潜在的未来方向提供了参考。

A Use Case of Patent Classification Using Deep Learning with Transfer Learning 使用深度学习和迁移学习的专利分类用例
Pub Date : 2022-08-01 DOI: 10.2478/jdis-2022-0015

Abstract Purpose Patent classification is one of the areas in Intellectual Property Analytics (IPA), and a growing use case since the number of patent applications has been increasing worldwide. We propose using machine learning algorithms to classify Portuguese patents and evaluate the performance of transfer learning methodologies to solve this task. Design/methodology/approach We applied three different approaches in this paper. First, we used a dataset available by INPI to explore traditional machine learning algorithms and ensemble methods. After preprocessing data by applying TF-IDF, FastText and Doc2Vec, the models were evaluated by cross-validation in 5 folds. In a second approach, we used two different Neural Networks architectures, a Convolutional Neural Network (CNN) and a bi-directional Long Short-Term Memory (BiLSTM). Finally, we used pre-trained BERT, DistilBERT, and ULMFiT models in the third approach. Findings BERTTimbau, a BERT architecture model pre-trained on a large Portuguese corpus, presented the best results for the task, even though with a performance of only 4% superior to a LinearSVC model using TF-IDF feature engineering. Research limitations The dataset was highly imbalanced, as usual in patent applications, so the classes with the lowest samples were expected to present the worst performance. That result happened in some cases, especially in classes with less than 60 training samples. Practical implications Patent classification is challenging because of the hierarchical classification system, the context overlap, and the underrepresentation of the classes. However, the final model presented an acceptable performance given the size of the dataset and the task complexity. This model can support the decision and improve the time by proposing a category in the second level of ICP, which is one of the critical phases of the grant patent process. Originality/value To our knowledge, the proposed models were never implemented for Portuguese patent classification.
摘要目的专利分类是知识产权分析(IPA)中的一个领域,自全球专利申请数量不断增加以来,它的使用案例越来越多。我们建议使用机器学习算法对葡萄牙专利进行分类,并评估迁移学习方法的性能以解决这一任务。设计/方法论/方法论我们在本文中采用了三种不同的方法。首先,我们使用INPI提供的数据集来探索传统的机器学习算法和集成方法。在应用TF-IDF、FastText和Doc2Vec对数据进行预处理后,通过交叉验证对模型进行了5次评估。在第二种方法中,我们使用了两种不同的神经网络架构,卷积神经网络(CNN)和双向长短期存储器(BiLSTM)。最后,我们在第三种方法中使用了预训练的BERT、DistilBERT和ULMFiT模型。研究结果BERTTimbau是一个在大型葡萄牙语语料库上预先训练的BERT架构模型,尽管其性能仅比使用TF-IDF特征工程的LinearSVC模型高4%,但它为该任务提供了最好的结果。研究限制数据集高度不平衡,就像专利申请中常见的那样,因此样本最少的类预计会表现出最差的性能。这种结果发生在某些情况下,尤其是在训练样本少于60个的课堂上。实际意义专利分类具有挑战性,因为分级分类系统、上下文重叠以及类别代表性不足。然而,考虑到数据集的大小和任务的复杂性,最终模型呈现出可接受的性能。该模型可以通过在第二级ICP中提出一个类别来支持决策并缩短时间,这是授予专利过程的关键阶段之一。独创性/价值据我们所知,所提出的模型从未用于葡萄牙专利分类。

Abstract Purpose This article explores the implications of publication requirements for the research output of Ukrainian academics in Scopus in 1999–2019. As such it contributes to the existing body of knowledge on quantitative and qualitative effects of research evaluation policies. Design/methodology/approach Three metrics were chosen to analyse the implications of publication requirements for the quality of research output: publications in predatory journals, publications in local journals and publications per SNIP quartile from the disciplinary perspective. Findings Study results highlight, that, firstly, publications of Ukrainian authors in predatory journals rose to 1% in 2019. Secondly, the share of publications in local journals reached the peak of 47.3% in 2015. In 2019 it fell to 31.8%. Thirdly, though the total number of publications has risen dramatically since 2011, but the share of Q3+Q4 has exceeded the share of Q1+Q2. To summarise, the study findings highligh, that research evaluation policies are required to contain not only quantitative but also qualitative criteria. Research limitation The study does not explore in detail the effects of a particular type of publication requirements. Practical implications The findings of the study have practical implications for policymakers and university managers aimed to develop research evaluation policies. Originality/value This paper gains insights into the effects of publication requirements on the research output of Ukrainian academics in Scopus.
摘要目的本文探讨了发表要求对乌克兰学者1999-2009年Scopus研究成果的影响。因此,它有助于现有的关于研究评估政策的数量和质量影响的知识体系。设计/方法/方法选择了三个指标来分析出版要求对研究产出质量的影响:掠夺性期刊的出版物、地方期刊的出版物和学科角度的SNIP四分位数出版物。研究结果强调,首先,乌克兰作者在掠夺性期刊上的发表量在2019年上升到1%。其次,地方期刊的出版物份额在2015年达到了47.3%的峰值。2019年下降到31.8%。第三,尽管自2011年以来,出版物总数急剧上升,但第三季度和第四季度的份额已经超过了第一季度和第二季度的份额。总之,研究发现,研究评估政策不仅需要包含定量标准,还需要包含定性标准。研究限制该研究没有详细探讨特定类型的出版物要求的影响。实际意义研究结果对旨在制定研究评估政策的政策制定者和大学管理者具有实际意义。原创性/价值本文深入了解了发表要求对Scopus乌克兰学者研究成果的影响。

Abstract Purpose Measuring the exact technology complementarity between different institutions is necessary to obtain complementary technology resources for R&D cooperation. Design/methodology/approach This study constructs a morphology-driven method for measuring technology complementarity, taking medical field as an example. First, we calculate semantic similarities between subjects (S and S) and action-objects (AO and AO) based on the Metathesaurus, forming clusters of S and AO based on a semantic similarity matrix. Second, we identify key technology issues and methods based on clusters of S and AO. Third, a technology morphology matrix of several dimensions is constructed using morphology analysis, and the matrix is filled with subjects -action-objects (SAO) structures according to corresponding key technology issues and methods for different institutions. Finally, the technology morphology matrix is used to measure the technology complementarity between different institutions based on SAO. Findings The improved technology complementarity method based on SAO is more of a supplementary and refined framework for the traditional IPC method. Research limitations In future studies we will reprocess and identify the SAO structures which were not in the technology morphology matrix, and find other methods to characterize key technical issues and methods. Furthermore, we will add the comparison between proposed method and traditional and mostly used complementarity measurement method based on industry chain and industry code. Practical implications This study takes medical field as an example. The morphology-driven method for measuring technology complementarity can be migrated and applied for any given field. Originality/value From the perspective of complementary technology resources, this study develops and tests a more accurate morphology-driven method for technology complementarity measurement.
摘要目的衡量不同机构之间的确切技术互补性是获得研发合作互补技术资源的必要条件。设计/方法论/方法本研究以医学领域为例,构建了一种形态学驱动的技术互补性测量方法。首先,我们基于元词库计算主体(S和S)和动作对象(AO和AO)之间的语义相似性,基于语义相似性矩阵形成S和AO的聚类。第二,基于S和AO聚类识别关键技术问题和方法。第三,利用形态学分析构建了一个多维度的技术形态矩阵,并根据不同机构对应的关键技术问题与方法,在矩阵中填充主体-行动对象(SAO)结构。最后,利用技术形态矩阵来衡量基于SAO的不同机构之间的技术互补性。研究结果基于SAO的改进技术互补方法是对传统IPC方法的补充和细化。研究局限性在未来的研究中,我们将重新处理和识别不在技术形态矩阵中的SAO结构,并找到其他方法来表征关键技术问题和方法。此外,我们还将添加所提出的方法与传统的、最常用的基于产业链和行业代码的互补性测量方法的比较。实际意义本研究以医学领域为例。测量技术互补性的形态学驱动方法可以迁移并应用于任何给定的领域。原创性/价值从技术资源互补的角度,本研究开发并测试了一种更准确的形态学驱动的技术互补性测量方法。

Originality/value From the perspective of complementary technology resources, this study develops and tests a more accurate morphology-driven method for technology complementarity measurement.","PeriodicalId":92237,"journal":{"name":"Journal of data and information science (Warsaw, Poland)","volume":"7 1","pages":"20 - 48"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47492432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Convergence of Impact Measures and Impact Bundles 影响测度和影响束的收敛性
Pub Date : 2022-07-16 DOI: 10.2478/jdis-2022-0014

Abstract Purpose A new point of view in the study of impact is introduced. Design/methodology/approach Using fundamental theorems in real analysis we study the convergence of well-known impact measures. Findings We show that pointwise convergence is maintained by all well-known impact bundles (such as the h-, g-, and R-bundle) and that the μ-bundle even maintains uniform convergence. Based on these results, a classification of impact bundles is given. Research limitations As for all impact studies, it is just impossible to study all measures in depth. Practical implications It is proposed to include convergence properties in the study of impact measures. Originality/value This article is the first to present a bundle classification based on convergence properties of impact bundles.
摘要目的介绍冲击研究的一个新观点。设计/方法论/方法利用实分析中的基本定理,我们研究了众所周知的影响测度的收敛性。我们的发现表明,所有已知的影响丛(如h-、g-和R-丛)都保持了逐点收敛,μ-丛甚至保持了一致收敛。基于这些结果,给出了冲击束的分类。研究局限性对于所有的影响研究来说,不可能深入研究所有的措施。实际意义建议在影响措施的研究中包括收敛特性。原创性/价值本文首次提出了一种基于冲击束收敛特性的束分类。
