PurposeGenre classification of songs based on lyrics is a challenging task even for humans, however, state-of-the-art natural language processing has recently offered advanced solutions to this task. The purpose of this study is to advance the understanding and application of natural language processing and deep learning in the domain of music genre classification, while also contributing to the broader themes of global knowledge and communication, and sustainable preservation of cultural heritage.Design/methodology/approachThe main contribution of this study is the development and evaluation of various machine and deep learning models for song genre classification. Additionally, we investigated the effect of different word embeddings, including Global Vectors for Word Representation (GloVe) and Word2Vec, on the classification performance. The tested models range from benchmarks such as logistic regression, support vector machine and random forest, to more complex neural network architectures and transformer-based models, such as recurrent neural network, long short-term memory, bidirectional long short-term memory and bidirectional encoder representations from transformers (BERT).FindingsThe authors conducted experiments on both English and multilingual data sets for genre classification. The results show that the BERT model achieved the best accuracy on the English data set, whereas cross-lingual language model pretraining based on RoBERTa (XLM-RoBERTa) performed the best on the multilingual data set. This study found that songs in the metal genre were the most accurately labeled, as their text style and topics were the most distinct from other genres. On the contrary, songs from the pop and rock genres were more challenging to differentiate. This study also compared the impact of different word embeddings on the classification task and found that models with GloVe word embeddings outperformed Word2Vec and the learning embedding layer.Originality/valueThis study presents the implementation, testing and comparison of various machine and deep learning models for genre classification. The results demonstrate that transformer models, including BERT, robustly optimized BERT pretraining approach, distilled bidirectional encoder representations from transformers, bidirectional and auto-regressive transformers and XLM-RoBERTa, outperformed other models.
基于歌词的歌曲类型分类即使对人类来说也是一项具有挑战性的任务,然而,最新的自然语言处理技术最近为这项任务提供了先进的解决方案。本研究的目的是促进自然语言处理和深度学习在音乐类型分类领域的理解和应用,同时也为全球知识和交流以及文化遗产的可持续保护等更广泛的主题做出贡献。设计/方法/方法本研究的主要贡献是开发和评估用于歌曲类型分类的各种机器和深度学习模型。此外,我们研究了不同的词嵌入,包括全局词表示向量(GloVe)和Word2Vec,对分类性能的影响。测试的模型范围从逻辑回归、支持向量机和随机森林等基准,到更复杂的神经网络架构和基于变压器的模型,如循环神经网络、长短期记忆、双向长短期记忆和来自变压器的双向编码器表示(BERT)。作者在英语和多语言数据集上进行了体裁分类实验。结果表明,BERT模型在英语数据集上的准确率最高,而基于RoBERTa (XLM-RoBERTa)的跨语言语言模型预训练在多语言数据集上的准确率最高。这项研究发现,金属音乐类型的歌曲被贴上了最准确的标签,因为它们的文本风格和主题与其他类型的歌曲最不同。相反,流行歌曲和摇滚歌曲更难区分。本研究还比较了不同词嵌入对分类任务的影响,发现GloVe词嵌入模型优于Word2Vec和学习嵌入层。原创性/价值本研究展示了用于类型分类的各种机器和深度学习模型的实现、测试和比较。结果表明,变压器模型,包括BERT,稳健优化的BERT预训练方法,从变压器,双向和自回归变压器以及XLM-RoBERTa中提取双向编码器表示,优于其他模型。

PurposeThe purpose of this study is to investigate individuals’ perceptions and behavior when dealing with misinformation on social media platforms. While misinformation is not a new phenomenon, the COVID-19 outbreak has accelerated its spread through social media outlets, leading to widespread exposure to false or misleading information. This exposure can have serious consequences on individuals’ decision-making and behavior, especially when it comes to critical decisions related to education or healthcare. The use of social media as a source of information makes it essential to understand how people perceive and respond to misinformation to develop effective strategies for mitigating its harmful effects.Design/methodology/approachThis large-scale study explores the Omani individuals’ perceptions and behaviour of misinformation on the social Web in a series of studies that seek to enhance the authorities’ response to misinformation. The study adopted a quantitative approach to collect data. Using WhatsApp as a social networking platform, a survey was disseminated to capture participants’ perceptions and behaviour among different segments of citizens in Oman.FindingsThe findings showed that Omani participants have high verification skills, implying high information literacy skills among them. Additionally, results indicated that misinformation had created doubt and anxiety among the participants. Moreover, it hindered many participants’ ability to take countermeasures and obtain reliable data.Originality/valueThis study was a large-scale study conducted in Oman, making it one of a few studies conducted in the region about perceptions and behaviour towards misinformation. The findings help to understand how different cultures interacted with COVID-19 misinformation. In addition, these findings offer useful insight that can help health information professionals to design preventive resources that help people to obtain accurate information during crises.
本研究的目的是调查个人在处理社交媒体平台上的错误信息时的感知和行为。虽然错误信息不是一个新现象,但2019冠状病毒病疫情加速了其通过社交媒体的传播,导致人们广泛接触到虚假或误导性信息。这种暴露可能对个人的决策和行为产生严重后果,特别是在涉及与教育或医疗保健相关的关键决策时。利用社交媒体作为信息来源,必须了解人们如何看待和应对错误信息,以制定有效的战略来减轻其有害影响。设计/方法/方法这项大规模研究探讨了阿曼个人对社交网络上错误信息的感知和行为,旨在加强当局对错误信息的反应。这项研究采用了定量方法来收集数据。利用WhatsApp作为社交网络平台,传播了一项调查,以了解阿曼不同阶层公民的参与者的看法和行为。调查结果显示,阿曼参与者具有较高的验证技能,这意味着他们具有较高的信息素养。此外,结果表明,错误信息在参与者中产生了怀疑和焦虑。此外,它阻碍了许多参与者采取对策和获得可靠数据的能力。原创性/价值这项研究是在阿曼进行的一项大规模研究,使其成为该地区关于对错误信息的看法和行为的少数研究之一。这些发现有助于了解不同文化如何与COVID-19错误信息相互作用。此外,这些发现提供了有用的见解,可以帮助卫生信息专业人员设计预防资源,帮助人们在危机期间获得准确的信息。

PurposeProtean career orientation is a key element that helps explain why workers plan and manage their careers. In the field of nursing, a protean career orientation assists nurses in job search, career mobility and adapting to changing demands. Few studies have explored how nurses’ protean career orientation will lead to job search and how to make better use of the protean career orientation. This study aims to explore how a protean career orientation influences job search via career optimism and the moderating role of mentoring relationships.Design/methodology/approachThis study conducted a cross-sectional survey of 309 frontline nurses from China. The questionnaire was distributed to nurses through the snowball sampling method. Jamovi 1.2.2 was used for descriptive analysis and Pearson’s correlation analysis. The relationships between the variables and their significance were tested using Process Macro 3.3.FindingsResults show that protean career orientation was significantly related to career optimism and positively related to job search. Career optimism was significantly related to job search. The indirect effect of protean career orientation on job search through career optimism was significant. The interaction between protean career orientation and mentoring relationships was also significantly related to career optimism.Originality/valueTo the best of the authors’ knowledge, this study is the first to demonstrate how nurses’ flexible career orientation significantly impacted job search through nurses’ career optimism. If nurses work in supportive mentoring relationships, the positive effect of the nurse’s protean career orientation on the job search is decreased.
多样的职业定位是一个关键因素,有助于解释为什么员工计划和管理他们的职业生涯。在护理领域,多样化的职业定位有助于护士寻找工作,职业流动性和适应不断变化的需求。很少有研究探讨护士的多变性职业取向对求职的影响以及如何更好地利用多变性职业取向。本研究旨在探讨多变的职业取向如何通过职业乐观主义影响求职,以及师徒关系的调节作用。本研究对来自中国的309名一线护士进行了横断面调查。问卷采用滚雪球抽样法发放给护士。采用Jamovi 1.2.2进行描述性分析和Pearson相关分析。使用Process Macro 3.3对变量之间的关系及其显著性进行检验。结果表明:职业取向与职业乐观显著相关,与求职正相关。职业乐观情绪与求职显著相关。多变性职业取向通过职业乐观对求职的间接影响显著。不同职业取向与师徒关系的交互作用对职业乐观度也有显著影响。原创性/价值据作者所知,本研究首次证明护士灵活的职业取向如何通过护士的职业乐观主义显著影响求职。如果护士在支持性师徒关系中工作,护士多变的职业取向对求职的积极作用就会减弱。

PurposeThis study aims to assess tribal women’s health information literacy in their daily lives. The specific objectives are to determine the tribe’s interest and frequency of seeking health-related information, to know their preferred health information sources and health-care methods for treatment and to find out the prospective barriers to searching for and finding health-related information.Design/methodology/approachA well-structured questionnaire was designed and surveyed among the tribal women of Khagrachhari, Bandarban and Mymensingh districts in Bangladesh. Stratified sampling was used, and 326 responses were retrieved. The collected data were analyzed using Statistical Package for Social Sciences version 20 and Microsoft Excel.FindingsMost of the tribal women are satisfied with their current health condition. Though they are highly interested in health-related information, they are very unusual in terms of searching for this kind of information. Vaccination information is their most desired information, and allopathic treatment is highly preferred by them. In this regard, they consult with doctors at nearby community clinics or government hospitals for different health issues. However, health information terminologies are often difficult for them to understand. High costs, lack of awareness and distance from health centers are significant barriers for tribal women seeking health-related information.Originality/valueTo the best of the authors’ knowledge, this is the first known effort in a developing country to study tribal women’s concerns regarding health-related issues.
目的本研究旨在评估部落妇女在日常生活中的健康信息素养。具体目标是确定部落寻求健康相关信息的兴趣和频率,了解他们首选的健康信息来源和保健治疗方法,并找出搜索和发现健康相关信息的潜在障碍。设计/方法/方法在孟加拉国Khagrachhari、Bandarban和Mymensingh地区的部落妇女中设计和调查了一份结构良好的问卷。采用分层抽样的方法,回收了326份回复。收集的数据使用Statistical Package for Social Sciences version 20和Microsoft Excel进行分析。大多数部落妇女对自己目前的健康状况感到满意。虽然他们对健康相关信息非常感兴趣,但在搜索这类信息方面,他们是非常不寻常的。疫苗接种信息是他们最需要的信息,对抗疗法治疗是他们的首选。在这方面,他们向附近的社区诊所或政府医院的医生咨询各种健康问题。然而,卫生信息术语对他们来说往往难以理解。高昂的费用、缺乏认识和远离保健中心是部落妇女寻求与健康有关的信息的重大障碍。原创性/价值据作者所知,这是在发展中国家首次研究部落妇女对健康相关问题的关注。

PurposeThe purpose of this study is to execute the application of confirmatory factor analysis in structural equation modeling, to investigate the reliability and validity of the proposed integrated digital library user success (IDLUS) scale in academic digital library computing information system in the area of information management and systems.Design/methodology/approachThe study analyzed 355 valid responses (MPhil and PhD) from the largest and oldest public sector university in Pakistan. Sample selection was calculated through a stratified random sampling technique from the four faculties of the University of the Punjab. The instrument was constructed based on the available two digital library and information system success models. The first model is Jung’s (1997) digital library user success model that is further composed of flow model (1977), end user computing satisfaction model (1987) and Joshi’s overall user satisfaction model (1990). Similarly, the second model is DeLone and McLean’s reformulated information system success (2003) theory. The question items used a five-point Likert scale and executed regression weights, standardized regression weights, convergent validity, variance extracted, construct reliability and discriminant validity to infer results.FindingsFindings show that the IDLUS scale has excellent validity and reliability estimates.Research limitations/implicationsThe study has theoretical implications for researchers and practical implications for information system developers.Originality/valueTo the best of the authors’ knowledge, this scale is the first-ever effort to measure the digital library user success in the context of Higher Education Commission-National Digital Library of Pakistan. Therefore, there was a dire need to conduct the psychometric analysis of the scale to examine the model fit statistics on the current sample in the particular cultural norms. Scale is based upon human factors taken from various Web success and information system success models from the fields of human–computer interaction information systems and computer-mediated communication.

PurposeUsage of updated technology is continuously empowering customer relationship management (CRM) to be convenient and user friendly, where customers are kept engaged with knowledge and information. This enables them on decision-making and managing their portfolio, especially in mutual fund investments. To improve toward a positive decision, certain quality related variables needed to be considered. Thus, this study aims to estimate the mediation effect of relationship quality and outcome (RQO) between CRM and investment decision-making in mutual funds (MFD).Design/methodology/approachThe descriptive study adopted the constructs from existing empirical literatures to conceptualize the model with three higher order constructs with 12 dimensions. Survey method is used, and with a structured questionnaire, a total of 323 mutual fund investors were approached using nonprobability criterion sampling technique, of which 262 relevant responses were considered for estimating the structural model. Smart PLS was used to establish the relationship of the constructs.FindingsThe result emphasizes a significant direct and indirect relationship indicating that investors are more inclined to MFD through technology-enabled CRM and RQO plays a vital role in explaining the direct relationship between CRM and MFD. The results of the study are in-line with the existing literature.Practical implicationsThe study highlights that financial institutions must focus not only on technological diffusion but also needs to ensure quality service by providing knowledge and information during every access of transactions by customers, making them independent and confident during investments.Originality/valueThis study indicates how capacity efficiency, which is a part of service productivity, can be managed without affecting the outcome efficiency by incorporating technology in the place of human interaction during relationship acquiring and retaining process.

PurposeThis study aims to investigate a framework for implementation of legislative framework governing records management throughout the life cycle in the Limpopo provincial government of South Africa.Design/methodology/approachThis quantitative multi-method study used a semi-structured questionnaire, document analysis and interviews to collect data. The dominant approach was quantitative, with some support from limited qualitative data, which served to clarify the statistical data. No sampling method was applied, as the study targeted the entire population of 135 records management participants from the provincial departments with the questionnaire, while nine participants from provincial archives participated in interviews.FindingsThe study revealed that the role of the provincial archives in enforcing compliance with legislative frameworks for the proper management of records was always disrupted by a lack of key resources such as staffing, for inspecting and training records-creating departments and working resources at the departmental levels.Research limitations/implicationsThe findings will contribute to the field in respect of future studies into compliance with records management legislation, and the proposed framework may be applied as a theoretical basis for, or part of, a conceptual framework.Practical implicationsThe study will serve as a resource or benchmark for archivists and records management professionals in the industry, as they count amongst the policymakers who find ways of monitoring, evaluating and enforcing compliance with the legislation governing proper records management.Social implicationsThe proper implementation of recommendations from this study will lead to significant improvements in the management of records with enduring value, allowing them to finally be transferred to an archival repository to serve the public interest as heritage, national memory, or resources for researchers and authors, amongst others.Originality/valueThe study proposes a framework for implementation of legislation governing records management with greater ease in the Limpopo provincial government of South Africa.
本研究旨在调查南非林波波省政府在整个生命周期内管理记录的立法框架的实施框架。设计/方法/方法本定量多方法研究采用半结构化问卷、文献分析和访谈来收集数据。主要的方法是定量的,有一些有限的定性数据的支持,这有助于澄清统计数据。本研究未采用抽样方法,问卷调查对象为135名省级部门档案管理参与者的全部人口,另有9名省级档案管理参与者参与访谈。研究结果表明,省级档案馆在遵守法律框架、妥善管理档案方面的作用总是被缺乏关键资源(如人员配备、检查和培训档案创建部门以及部门一级的工作资源)所破坏。研究的局限/影响研究结果将对未来有关遵守档案管理法例的研究有所助益,而建议的架构可作为概念架构的理论基础或一部分加以应用。实际意义这项研究将为业界的档案工作者和档案管理专业人员提供资源或基准,因为他们是决策者中的一员,他们需要找到方法来监督、评估和执行有关妥善档案管理的立法。社会意义正确实施本研究的建议将显著改善对具有持久价值的记录的管理,使它们最终能够转移到档案库,作为遗产、国家记忆或研究人员和作者的资源等服务于公众利益。原创性/价值本研究提出了一个框架,以便在南非林波波省政府更容易地实施管理记录的立法。

PurposeThis study aims to propose iStage, i.e. an intelligent hybrid deep learning (DL)-based framework to determine the stage of the disaster to make the right decisions at the right time.Design/methodology/approachiStage acquires data from the Twitter platform and identifies the social media message as pre, during, post-disaster or irrelevant. To demonstrate the effectiveness of iStage, it is applied on cyclonic and COVID-19 disasters. The considered disaster data sets are cyclone Fani, cyclone Titli, cyclone Amphan, cyclone Nisarga and COVID-19.FindingsThe experimental results demonstrate that the iStage outperforms Long Short-Term Memory Network and Convolutional Neural Network models. The proposed approach returns the best possible solution among existing research studies considering different evaluation metrics – accuracy, precision, recall, f-score, the area under receiver operating characteristic curve and the area under precision-recall curve.Originality/valueiStage is built using the hybrid architecture of DL models. It is effective in decision-making. The research study helps coordinate disaster activities in a more targeted and timely manner.
本研究旨在提出iStage,即基于智能混合深度学习(DL)的框架,以确定灾难的阶段,以便在正确的时间做出正确的决策。设计/方法/方法stage从Twitter平台获取数据,并将社交媒体信息识别为灾前、灾中、灾后或无关。为了证明iStage的有效性,将其应用于气旋和COVID-19灾害。考虑的灾害数据集是飓风“法尼”、飓风“提特利”、飓风“安潘”、飓风“尼萨尔加”和COVID-19。实验结果表明,iStage优于长短期记忆网络和卷积神经网络模型。该方法在现有研究中考虑了不同的评估指标——准确度、精密度、召回率、f分、接收者工作特征曲线下面积和精确召回率曲线下面积,得出了可能的最佳解决方案。Originality/valueiStage是使用DL模型的混合架构构建的。它是有效的决策。这项研究有助于更有针对性和及时地协调灾害活动。
