PurposeExperiments are the backbone of the development process of data-driven predictive models for scientific applications. The quality of the experiments directly impacts the model performance. Uncertainty inherently affects experiment measurements and is often missing in the available data sets due to its estimation cost. For similar reasons, experiments are very few compared to other data sources. Discarding experiments based on the missing uncertainty values would preclude the development of predictive models. Data profiling techniques are fundamental to assess data quality, but some data quality dimensions are challenging to evaluate without knowing the uncertainty. In this context, this paper aims to predict the missing uncertainty of the experiments.Design/methodology/approachThis work presents a methodology to forecast the experiments’ missing uncertainty, given a data set and its ontological description. The approach is based on knowledge graph embeddings and leverages the task of link prediction over a knowledge graph representation of the experiments database. The validity of the methodology is first tested in multiple conditions using synthetic data and then applied to a large data set of experiments in the chemical kinetic domain as a case study.FindingsThe analysis results of different test case scenarios suggest that knowledge graph embedding can be used to predict the missing uncertainty of the experiments when there is a hidden relationship between the experiment metadata and the uncertainty values. The link prediction task is also resilient to random noise in the relationship. The knowledge graph embedding outperforms the baseline results if the uncertainty depends upon multiple metadata.Originality/valueThe employment of knowledge graph embedding to predict the missing experimental uncertainty is a novel alternative to the current and more costly techniques in the literature. Such contribution permits a better data quality profiling of scientific repositories and improves the development process of data-driven models based on scientific experiments.
目的实验是科学应用数据驱动预测模型开发过程的支柱。实验的质量直接影响模型的性能。不确定性固有地影响实验测量,并且由于其估计成本而经常在可用数据集中丢失。由于类似的原因,与其他数据源相比,实验很少。放弃基于缺失的不确定性值的实验将阻碍预测模型的发展。数据分析技术是评估数据质量的基础,但是在不知道不确定性的情况下,对一些数据质量维度进行评估是具有挑战性的。在此背景下,本文旨在预测实验中缺失的不确定性。设计/方法/方法本工作提出了一种预测实验缺失不确定性的方法,给出了数据集及其本体论描述。该方法基于知识图嵌入,并在实验数据库的知识图表示上利用链接预测任务。首先在多种条件下使用合成数据测试了该方法的有效性,然后将其应用于化学动力学领域的大量实验数据集作为案例研究。发现不同测试用例场景的分析结果表明,当实验元数据与不确定性值之间存在隐藏关系时,知识图嵌入可以用于预测实验缺失的不确定性。链路预测任务还具有抗随机噪声的能力。如果不确定性依赖于多个元数据,则知识图嵌入优于基线结果。原创性/价值利用知识图嵌入来预测缺失的实验不确定性是文献中当前和更昂贵的技术的一种新颖的替代方案。这种贡献允许对科学存储库进行更好的数据质量分析,并改进基于科学实验的数据驱动模型的开发过程。

PurposeThis study aims to evaluate a method of building a biomedical knowledge graph (KG).Design/methodology/approachThis research first constructs a COVID-19 KG on the COVID-19 Open Research Data Set, covering information over six categories (i.e. disease, drug, gene, species, therapy and symptom). The construction used open-source tools to extract entities, relations and triples. Then, the COVID-19 KG is evaluated on three data-quality dimensions: correctness, relatedness and comprehensiveness, using a semiautomatic approach. Finally, this study assesses the application of the KG by building a question answering (Q&A) system. Five queries regarding COVID-19 genomes, symptoms, transmissions and therapeutics were submitted to the system and the results were analyzed.FindingsWith current extraction tools, the quality of the KG is moderate and difficult to improve, unless more efforts are made to improve the tools for entity extraction, relation extraction and others. This study finds that comprehensiveness and relatedness positively correlate with the data size. Furthermore, the results indicate the performances of the Q&A systems built on the larger-scale KGs are better than the smaller ones for most queries, proving the importance of relatedness and comprehensiveness to ensure the usefulness of the KG.Originality/valueThe KG construction process, data-quality-based and application-based evaluations discussed in this paper provide valuable references for KG researchers and practitioners to build high-quality domain-specific knowledge discovery systems.
目的本研究旨在评估建立生物医学知识图谱(KG)的方法。设计/方法论/方法本研究首先在新冠肺炎开放研究数据集上构建了一个新冠肺炎知识图谱,涵盖了六个类别(即疾病、药物、基因、物种、治疗和症状)的信息。该构建使用开源工具来提取实体、关系和三元组。然后,使用半自动方法,从正确性、相关性和全面性三个数据质量维度对新冠肺炎KG进行评估。最后,本研究通过建立问答系统来评估KG的应用。向系统提交了关于新冠肺炎基因组、症状、传播和治疗的五个查询,并对结果进行了分析。发现使用当前的提取工具,KG的质量是中等的,很难提高,除非做出更多的努力来改进实体提取、关系提取等工具。本研究发现,综合性和相关性与数据量呈正相关。此外,结果表明,在大多数查询中,建立在较大规模KGs上的问答系统的性能优于较小规模KGs,证明了相关性和全面性对确保KG.Originality/value有用性的重要性,本文讨论的基于数据质量和基于应用程序的评估为KG的研究人员和从业者构建高质量的领域特定知识发现系统提供了宝贵的参考。

PurposeThis study aims to understand how informational factors influence online purchase intention when considering secondhand books.Design/methodology/approachA conceptual model linking book condition, description, delivery cost, picture, sellers’ rating and delivery date to purchase intention was developed and tested by using structural equation modeling. Survey data from 234 respondents was used to analyze both direct and mediating relationships.FindingsThe examination demonstrates how book condition, delivery cost and sellers’ rating influence consumers’ purchase intention. Book condition directly and indirectly influenced purchase intention, while delivery cost and sellers’ rating were significant only when including the mediating variable delivery date.Originality/valueThis work clarifies where resources should be allocated when offering secondhand books online. Sellers should dedicate time to include informational factors such as book condition, delivery cost and sellers’ rating. Contra wise, there is little value expounding on the book’s description or providing a high-quality picture when selling online.
目的本研究旨在了解资讯因素对二手书网上购买意愿的影响。设计/方法/方法建立了一个将图书状况、描述、交货成本、图片、卖家评级和交货日期与购买意愿联系起来的概念模型,并利用结构方程模型进行了测试。来自234名受访者的调查数据用于分析直接关系和中介关系。研究结果表明,图书状况、配送成本和卖家评级对消费者购买意愿的影响。账面状况直接和间接影响购买意愿,而配送成本和卖家评级只有在包含中介变量配送日期时才显著。原创性/价值这项工作阐明了在网上提供二手书时应该在哪里分配资源。卖家应该花时间将信息因素包括在内,如书籍状况,运输成本和卖家的评级。相反,在网上销售时,详述书的描述或提供高质量的图片几乎没有价值。

PurposeThe multitasking phenomenon has been prevailing in the technology-driven information environment. People are engaged in multitasking to process information and deal with personal and professional information tasks. This study aims to explore the external predictors of multitasking information behavior (MIB) of library and information science (LIS) professionals from Pakistan.Design/methodology/approachThis is a quantitative study based on a questionnaire survey, and data was collected through Google Form; the link was shared via e-mail and WhatsApp to get maximum responses. The sampling includes the LIS professionals working in Higher Education Commission-recognized universities of Khyber Pakhtunkhwa (KPK), Pakistan. A total of 126 responses were received from 41 universities of KPK.FindingsPearson correlation and regression were applied by using SPSS for data analysis. The findings revealed that time pressure (TP) is a good predictor of multitasking because when professionals got tasks with deadlines, they try to perform multiple activities at a time. Therefore, TP is a predictor of human MIB. This study also revealed that the work environment is a less significant predictor of MIB, and the use of multiple information resources is a weak predictor of MIB. It is noted that individual covariates were not predictors of the multitasking information. However, TP was the most significant predictor among all the contextual and individual factors predicting MIB.Research limitations/implicationsThis research line is significant because MIB is a new dimension of human information behavior among LIS professionals. The findings are beneficial for LIS professionals to increase their work productivity and performance by rationalizing the significant predictors.Originality/valueTo the best of the authors’ knowledge, no such study is available that highlighted the MIB among LIS professionals. Therefore, this study will highlight external factors’ effects on LIS professionals’ MIB. This study will contribute to the literature on libraries and information management as this study describes the LIS professionals’ behavior.
在技术驱动的信息环境中,多任务处理现象非常普遍。人们从事多任务处理信息和处理个人和专业信息任务。本研究旨在探讨巴基斯坦图书馆情报学专业人员多任务信息行为(MIB)的外部预测因素。设计/方法/方法本研究是基于问卷调查的定量研究,数据通过谷歌Form收集;这个链接通过电子邮件和WhatsApp分享,以获得最大的回应。抽样包括在巴基斯坦开伯尔-普赫图赫瓦省高等教育委员会认可的大学工作的美国专业人员。我们共收到来自肃贪会41所大学的126份回应。采用SPSS统计软件进行spearson相关和回归分析。研究结果表明,时间压力(TP)是多任务处理的一个很好的预测指标,因为当专业人士接到有截止日期的任务时,他们会试图一次完成多项任务。因此,TP是人类MIB的一个预测因子。本研究还发现,工作环境对MIB的预测作用不显著,而多种信息资源的使用对MIB的预测作用较弱。值得注意的是,个体协变量不是多任务信息的预测因子。然而,在所有预测MIB的情境和个体因素中,TP是最显著的预测因子。研究局限/启示这条研究路线意义重大,因为MIB是LIS专业人员中人类信息行为的一个新维度。研究结果有助于LIS专业人员通过合理化重要预测因子来提高他们的工作效率和绩效。原创性/价值据作者所知,没有这样的研究在美国专业人士中突出了MIB。因此,本研究将重点关注外部因素对LIS专业人员MIB的影响。由于本研究描述了图书馆专业人员的行为,本研究将有助于图书馆与信息管理的文献。

PurposeThe purpose of this paper is to identify the antecedents of continued usage intentions in the connected devices ecosystem in health care by analyzing the users' and physicians' expectations in a new ecosystem where one prefers to connect digitally rather than physically.Design/methodology/approachThis is a unique study in which data was collected from 242 doctors and 215 end-users to gauge the expectations from the connected devices in health care. Further, these responses were hypothesised using UTAUT-2 and ECT theories to analyze general users’ and professional users’ or doctors’ expectations for continued usage in connected devices ecosystem in the health-care ecosystem.FindingsPerformance expectancy, social influence, facilitating conditions and price value emerged as significant predictors of satisfaction in both user groups. But habit and hedonic motivation reflected an insignificant impact on user satisfaction. Surprisingly, effort expectancy emerged as a significant factor for end-user satisfaction, and this became insignificant for professional user satisfaction. Satisfaction was positively related to continued usage for both user groups, and app quality has a positive impact on all the predictors.Practical implicationsTo the best of the authors’ knowledge, this is the first comparative study to understand the factors which influence consumer behavior leading to a holistic model and can be imbibed for creating a better customer experience in an era where we are more comfortable connecting digitally rather than physically.Originality/valueThis study has used the Unified Theory of Acceptance and Use of Technology-2 model and expectation confirmation theory to analyze the key factors influencing the intentions for continued usage of devices in the Internet of Medical Devices setup.
目的本文的目的是通过分析用户和医生在一个更喜欢数字连接而不是物理连接的新生态系统中的期望,来确定医疗保健中连接设备生态系统中持续使用意图的前因。设计/方法/方法这是一项独特的研究,从242名医生和215名最终用户那里收集了数据,以衡量医疗保健中连接设备的期望值。此外,这些反应是使用UTAUT-2和ECT理论假设的,以分析普通用户和专业用户或医生对医疗保健生态系统中连接设备生态系统中继续使用的期望。发现性能预期、社会影响、便利条件和价格价值是两个用户群体满意度的重要预测因素。但习惯和享乐动机对用户满意度的影响并不显著。令人惊讶的是,预期工作量成为最终用户满意度的一个重要因素,而这对专业用户满意度来说变得微不足道。满意度与两个用户组的持续使用呈正相关,应用程序质量对所有预测因素都有积极影响。实践含义据作者所知,这是第一项比较研究,旨在了解影响消费者行为的因素,从而建立一个整体模型,并可在我们更愿意通过数字而非物理连接的时代创造更好的客户体验。独创性/价值本研究采用技术接受和使用统一理论-2模型和期望确认理论,分析了影响医疗器械互联网设置中继续使用器械意愿的关键因素。

PurposeThis paper aims to identify computational thinking (CT) in 4th to 6th grade students in the context of project-based problem-solving while engaged in an after-school program.Design/methodology/approachThis case study approach was selected due to its suitability for answering “how” or “why” questions about real-world phenomena within a set context (Creswell and Poth, 2018; Yin, 2018). This was an appropriate fit given the context of an after-school program and the research question asked how to identify learners’ demonstrated CT through project-based learning hands-on activities and problem-solving in a naturalistic environment.FindingsResults show that heuristics, algorithms and conditional logic were observed more than other components of CT such as data collection, simulations and modeling. Descriptions of common activities in a naturalistic learning environment are presented to illustrate how the students practiced CT over time, which could help readers develop an understanding of CT in conjunction with hands-on problem-solving activities in elementary students. Identifying and classifying CT in this study focused on students’ learning process.Originality/valueThis study contributes to the challenging field of evaluating CT while focusing on observable behaviors and problem-solving activities with various degrees of teacher’s facilitation instead of final artifacts. Implications for researchers and educators interested in integrating CT in K-12 learning and its assessment are discussed.
目的本文旨在识别4-6年级学生在参与课后项目时,在基于项目的问题解决背景下的计算思维(CT)。设计/方法论/方法之所以选择这种案例研究方法,是因为它适合在一定的背景下回答关于现实世界现象的“如何”或“为什么”问题(Creswell和Poth,2018;尹,2018)。考虑到课后项目的背景,这是一个合适的选择,研究问题是如何通过基于项目的学习实践活动和在自然环境中解决问题来识别学习者表现出的CT。结果表明,启发式、算法和条件逻辑比CT的其他组成部分(如数据收集、模拟和建模)得到了更多的观察。介绍了自然学习环境中的常见活动,以说明学生如何随着时间的推移练习CT,这可以帮助读者结合小学生的动手解决问题活动来理解CT。在本研究中,CT的识别和分类侧重于学生的学习过程。独创性/价值这项研究有助于评估CT这一具有挑战性的领域,同时关注可观察到的行为和解决问题的活动,以及不同程度的教师促进,而不是最终的人工制品。讨论了对有兴趣将CT纳入K-12学习及其评估的研究人员和教育工作者的启示。

PurposeSocial media allow for observing different aspects of human behaviour, in particular, those that can be evaluated from explicit user expressions. Based on a data set of posts with user opinions collected from social media, this paper aims to show an insight into how the readers of different news portals react to online content. The focus is on users’ emotions about the content, so the findings of the analysis provide a further understanding of how marketers should structure and deliver communication content such that it promotes positive engagement behaviour.Design/methodology/approachMore than 5.5 million user comments to posted messages from 15 worldwide popular news portals were collected and analysed, where each post was evaluated based on a set of variables that represent either structural (e.g. embedded in intra- or inter-message structure) or behavioural (e.g. exhibiting a certain behavioural pattern that appeared in response to a posted message) component of expressions. The conclusions are based on a set of regression models and exploratory factor analysis.FindingsThe findings show and theorise the influence of social media content on emotional user engagement. This provides a more comprehensive understanding of the engagement attributed to social media content and, consequently, could be a better predictor of future behaviour.Originality/valueThis paper provides original data analysis of user comments and emotional reactions that appeared on social media news websites in 2018.

A clustering approach for data quality results of research information systems 研究信息系统数据质量结果的聚类方法
IF 2.1 Q1 Social Sciences Pub Date : 2022-11-03 DOI: 10.1108/idd-07-2022-0063

PurposeThe overall goal of the data mining process is to extract information from an extensive data set and make it understandable for further use. When working with large volumes of unstructured data in research information systems, it is necessary to divide the information into logical groupings after examining their quality before attempting to analyze it. On the other hand, data quality results are valuable resources for defining quality excellence programs of any information system. Hence, the purpose of this study is to discover and extract knowledge to evaluate and improve data quality in research information systems.Design/methodology/approachClustering in data analysis and exploiting the outputs allows practitioners to gain an in-depth and extensive look at their information to form some logical structures based on what they have found. In this study, data extracted from an information system are used in the first stage. Then, the data quality results are classified into an organized structure based on data quality dimension standards. Next, clustering algorithms (K-Means), density-based clustering (density-based spatial clustering of applications with noise [DBSCAN]) and hierarchical clustering (balanced iterative reducing and clustering using hierarchies [BIRCH]) are applied to compare and find the most appropriate clustering algorithms in the research information system.FindingsThis paper showed that quality control results of an information system could be categorized through well-known data quality dimensions, including precision, accuracy, completeness, consistency, reputation and timeliness. Furthermore, among different well-known clustering approaches, the BIRCH algorithm of hierarchical clustering methods performs better in data clustering and gives the highest silhouette coefficient value. Next in line is the DBSCAN method, which performs better than the K-Means method.Research limitations/implicationsIn the data quality assessment process, the discrepancies identified and the lack of proper classification for inconsistent data have led to unstructured reports, making the statistical analysis of qualitative metadata problems difficult and thus impossible to root out the observed errors. Therefore, in this study, the evaluation results of data quality have been categorized into various data quality dimensions, based on which multiple analyses have been performed in the form of data mining methods.Originality/valueAlthough several pieces of research have been conducted to assess data quality results of research information systems, knowledge extraction from obtained data quality scores is a crucial work that has rarely been studied in the literature. Besides, clustering in data quality analysis and exploiting the outputs allows practitioners to gain an in-depth and extensive look at their information to form some logical structures based on what they have found.
目的数据挖掘过程的总体目标是从广泛的数据集中提取信息,并使其易于理解以供进一步使用。在研究信息系统中处理大量非结构化数据时,有必要在检查信息质量后将其划分为逻辑分组,然后再进行分析。另一方面,数据质量结果是定义任何信息系统的卓越质量计划的宝贵资源。因此,本研究的目的是发现和提取知识,以评估和提高研究信息系统中的数据质量。设计/方法论/方法数据分析中的聚类和利用输出使从业者能够深入而广泛地查看他们的信息,并根据他们的发现形成一些逻辑结构。在这项研究中,从信息系统中提取的数据被用于第一阶段。然后,基于数据质量维度标准将数据质量结果分类到有组织的结构中。接下来,应用聚类算法(K-Means)、基于密度的聚类(具有噪声的应用程序的基于密度的空间聚类[DBSCAN])和层次聚类(使用层次结构的平衡迭代约简和聚类[BICH])来比较和找到研究信息系统中最合适的聚类算法。研究结果表明,信息系统的质量控制结果可以通过众所周知的数据质量维度进行分类,包括准确性、准确性、完整性、一致性、信誉和及时性。此外,在不同的已知聚类方法中,层次聚类方法的BIRCH算法在数据聚类中表现更好,并且给出了最高的剪影系数值。接下来是DBSCAN方法,它的性能比K-Means方法好。研究局限性/含义在数据质量评估过程中,发现的差异和对不一致数据缺乏适当分类导致了非结构化报告,使定性元数据问题的统计分析变得困难,因此无法根除观察到的错误。因此,在本研究中,数据质量的评估结果被归类为不同的数据质量维度,在此基础上,以数据挖掘方法的形式进行了多重分析。原创性/价值尽管已经进行了几项研究来评估研究信息系统的数据质量结果,但从所获得的数据质量分数中提取知识是一项文献中很少研究的关键工作。此外,数据质量分析中的聚类和利用输出使从业者能够深入而广泛地查看他们的信息,并根据他们的发现形成一些逻辑结构。
