背景与挑战
背景概述
Dhoroni数据集由Azmine Toushik Wasi等研究人员于2024年创建,旨在填补孟加拉语气候变化和环境观点研究中的空白。该数据集包含2300篇孟加拉语新闻文章,涵盖了气候变化和环境问题的多个视角,如政治影响、科学数据、立场检测等。通过详细的探索性分析和十种不同的标注视角,Dhoroni数据集为孟加拉语气候变化话语的分析提供了丰富的资源。此外,研究团队还开发了基于BanglaBERT的Dhoroni模型家族,用于不同任务的基准测试,展示了在不同任务中的稳定性能。这一研究不仅增强了孟加拉语气候讨论的可访问性和分析性,还为气候影响地区的沟通和研究差距提供了重要解决方案。
当前挑战
Dhoroni数据集面临的挑战主要集中在解决领域问题和构建过程中。首先,该数据集旨在解决孟加拉语气候变化和环境观点的领域问题,这需要克服语言资源有限和国际舞台上语言代表性不足的问题。其次,在构建过程中,研究人员面临了多视角标注的复杂性,确保标注的一致性和准确性是一个重大挑战。此外,数据集的动态性要求定期更新,以反映气候科学、政策和公众情绪的最新发展。最后,尽管数据集在多个任务中展示了稳定的性能,但在某些复杂任务如气候/环境主题检测和新闻目标检测中,模型的表现仍有待提升。
常用场景
经典使用场景
Dhoroni数据集的经典使用场景在于通过自然语言处理技术,深入分析孟加拉语新闻文章中关于气候变化和环境问题的多角度观点。该数据集包含了2300篇经过多重标注的新闻文章,涵盖了政治影响、科学数据、新闻真实性等多个维度。通过这些标注,研究者可以训练模型来检测新闻中的立场、政治影响、科学数据的使用情况等,从而为气候变化和环境问题的研究提供丰富的语料库。
实际应用
在实际应用中,Dhoroni数据集可以被政府机构、非政府组织和媒体机构用于监测和分析公众对气候变化的态度和反应。例如,政策制定者可以利用该数据集来评估公众对气候政策的接受度,从而调整和优化政策。媒体机构则可以通过分析数据集中的新闻内容,提高报道的准确性和客观性,减少气候变化相关信息的误导。此外,该数据集还可以用于教育和培训,帮助公众更好地理解气候变化及其影响。
衍生相关工作
Dhoroni数据集的发布催生了一系列相关研究工作,特别是在孟加拉语自然语言处理领域。例如,基于该数据集,研究者开发了BanglaBERT-Dhoroni系列模型,用于检测新闻中的立场、政治影响和科学数据使用情况。这些模型不仅提升了孟加拉语NLP任务的性能,还为其他低资源语言的类似研究提供了参考。此外,该数据集还激发了对多语言气候变化叙事的研究,推动了全球范围内气候变化相关数据的多样性和包容性。

CatMeows

该数据集包含440个声音样本,由21只属于两个品种(缅因州库恩猫和欧洲短毛猫)的猫在三种不同情境下发出的喵声组成。这些情境包括刷毛、在陌生环境中隔离和等待食物。每个声音文件都遵循特定的命名约定,包含猫的唯一ID、品种、性别、猫主人的唯一ID、录音场次和发声计数。此外,还有一个额外的zip文件,包含被排除的录音(非喵声)和未剪辑的连续发声序列。

Canadian Census

**Overview** The data package provides demographics for Canadian population groups according to multiple location categories: Forward Sortation Areas (FSAs), Census Metropolitan Areas (CMAs) and Census Agglomerations (CAs), Federal Electoral Districts (FEDs), Health Regions (HRs) and provinces. **Description** The data are available through the Canadian Census and the National Household Survey (NHS), separated or combined. The main demographic indicators provided for the population groups, stratified not only by location but also for the majority by demographical and socioeconomic characteristics, are population number, females and males, usual residents and private dwellings. The primary use of the data at the Health Region level is for health surveillance and population health research. Federal and provincial departments of health and human resources, social service agencies, and other types of government agencies use the information to monitor, plan, implement and evaluate programs to improve the health of Canadians and the efficiency of health services. Researchers from various fields use the information to conduct research to improve health. Non-profit health organizations and the media use the health region data to raise awareness about health, an issue of concern to all Canadians. The Census population counts for a particular geographic area representing the number of Canadians whose usual place of residence is in that area, regardless of where they happened to be on Census Day. Also included are any Canadians who were staying in that area on Census Day and who had no usual place of residence elsewhere in Canada, as well as those considered to be 'non-permanent residents'. National Household Survey (NHS) provides demographic data for various levels of geography, including provinces and territories, census metropolitan areas/census agglomerations, census divisions, census subdivisions, census tracts, federal electoral districts and health regions. In order to provide a comprehensive overview of an area, this product presents data from both the NHS and the Census. NHS data topics include immigration and ethnocultural diversity; aboriginal peoples; education and labor; mobility and migration; language of work; income and housing. 2011 Census data topics include population and dwelling counts; age and sex; families, households and marital status; structural type of dwelling and collectives; and language. The data are collected for private dwellings occupied by usual residents. A private dwelling is a dwelling in which a person or a group of persons permanently reside. Information for the National Household Survey does not include information for collective dwellings. Collective dwellings are dwellings used for commercial, institutional or communal purposes, such as a hotel, a hospital or a work camp. **Benefits** - Useful for canada public health stakeholders, for public health specialist or specialized public and other interested parties. for health surveillance and population health research. for monitoring, planning, implementation and evaluation of health-related programs. media agencies may use the health regions data to raise awareness about health, an issue of concern to all canadians. giving the addition of longitude and latitude in some of the datasets the data can be useful to transpose the values into geographical representations. the fields descriptions along with the dataset description are useful for the user to quickly understand the data and the dataset. **License Information** The use of John Snow Labs datasets is free for personal and research purposes.
