生物资源是国家重要的战略性资源。组学时代的到来催生数据量级的增长将推动生命科学研究向"数据密集型科学"的新范式转变。因此,生物资源的大数据与生物资源本身一样,也已成为国家战略资源,成为国际科技与产业竞争热点和战略制高点。目前,我国亟待加快建设国家级战略生物资源大数据共享平台,建立全面支撑生物资源保存、利用、开发、挖掘和可持续利用的技术体系,形成包括数据质控流程、数据存储中心、数据共享中心和数据转化中心的可对海量数据进行有效管理、高效分析和可用、易用的综合数据系统,支撑我国生物资源前沿领域科学发现和产业创新发展。中国科学院战略生物资源信息平台配合中国科学院战略生物资源服务网络的建设,形成了包括数据管理规范、数据汇集平台、数据门户和数据可视化系统在内的一套完整的数据生态,从而有效地促进了中国科学院战略生物资源数据的集成、共享、挖掘和利用。目前,该平台已经覆盖中国科学院植物园、标本馆、生物遗传资源、实验动物、生物多样性监测网络5类资源的42家单位,集成6 981 465条数据,且全部数据资源都可以通过数据门户进行共享。  相似文献   

认知建构视角下交互式信息检索模型研究   总被引：1，自引：0，他引：1  

刘萍  叶方倩  杨志伟 《图书情报知识》2020,(2):93-101,122

[目的/意义]信息检索本质上是一个认知过程,研究促进用户认知的交互式信息检索模型具有重要意义。[研究设计/方法]以建构主义理论为指导,以促进用户的认知发展为研究目标,构建了以信息空间层、用户空间层和界面交互层为顶层分析框架的交互式信息检索模型,并开发了原型系统。[结论/发现]实验结果表明原型系统能有效地促进用户对信息空间的探索与挖掘,帮助用户积极主动地进行认知建构,发展认知空间。[创新/价值]将认知建构理论运用于信息检索领域,从交互设计方面对检索系统提出了改进建议,以更好地提供认知支持。  相似文献   

我国档案社会记忆研究的文献计量及可视化分析     

李财富  靳文君 《山西档案》2020,(1):143-150

对档案学核心期刊中244篇档案社会记忆研究论文进行文献计量及双聚类分析,可以直观、科学地反映我国档案社会记忆研究的发展状况。我国档案社会记忆研究目前已趋于成熟发展阶段,研究主体呈现出多元化趋势,研究主题主要集中在后保管时代档案社会记忆价值构建、档案记忆和权力与身份认同的关系、非物质文化遗产及边缘弱势群体的档案记忆、数字档案记忆资源的整合和开发等方面。建议在档案社会记忆范式构建期继续深化理论研究深度,将档案社会记忆的学理性与应用性相结合,发挥理论研究的现实指导和发展预测功能。  相似文献   

Application of machine learning techniques to assess the trends and alignment of the funded research output     

《Journal of Informetrics》2020,14(2):101018

Research and development activities are regarded as one of the most influencing factors of the future of a country. Large investments in research can yield a tremendous outcome in terms of a country’s overall wealth and strength. However, public financial resources of countries are often limited which calls for a wise and targeted investment. Scientific publications are considered as one of the main outputs of research investment. Although the general trend of scientific publications is increasing, a detailed analysis is required to monitor the research trends and assess whether they are in line with the top research priorities of the country. Such focused monitoring can shed light on scientific activities evolution as well as the formation of new research areas, thus helping governments to adjust priorities, if required. But monitoring the output of the funded research manually is not only very expensive and difficult, it is also subjective. Using structural topic models, in this paper we evaluated the trends in academic research performed by federally funded Canadian researchers during the time-frame of 2000–2018, covering more than 140,000 research publications. The proposed approach makes it possible to objectively and systematically monitor research projects, or any other set of documents related to research activities such as funding proposals, at large-scale. Our results confirm the accordance between the performed federally funded research projects and the top research priorities of Canada.  相似文献   

创新扩散驱动的领域隐性知识地图构建：以微电子领域为例     

张云中  姚佳颖 《图书情报工作》2023,67(5):130-141

[目的 /意义]探究知识创新扩散路径下的隐性知识扩散和转移行为,据此构建蕴含专家学者隐性知识的知识地图,对推动知识共享与创新至关重要。[方法 /过程]首先从科学知识图谱与知识地图融合的角度明确创新扩散驱动的隐性知识地图构建原理,在此基础上建构隐性知识地图构建流程模型,并以微电子领域为例,围绕主题、学科、机构、地区4个维度内的创新扩散路径,衍生出隐性知识载体的内在关联,借助可视化方式构建隐性知识地图,探究专家隐性知识扩散和转移行为规律。[结果 /结论 ]提出以创新扩散为驱动的微电子领域内的隐性知识地图构建方案,追踪知识创新扩散脉络与隐性知识载体间知识流动行为,可充分满足专家定位、团队构建、专家推荐三个场景下的独特需求。  相似文献   

网络时代学习理论的新发展——连接主义   总被引：2，自引：0，他引：2  

刘菊  钟绍春 《外国教育研究》2011,(1)

连接主义(Connectivism)是国际上新近兴起的E-learning学习理论,被誉为里程碑式的数字时代学习理论。它从神经科学的角度出发,把学习描绘成大量节点相互联结构成网络整体的过程,表现出了比其他学习理论更灵活、更接近人脑实际的优越性。虽然仍有一部分人对连接主义引领网络时代学习理论发展的地位存有质疑,但该理论阐释学习本质的新颖观点和独特视角无疑将促进学习理论研究的新发展。  相似文献

Toward a taxonomy of entrepreneurship education research literature: A bibliometric mapping and visualization     

《Educational Research Review》2019

The retrospective amount of research literature dedicated to entrepreneurship education (EE) is overwhelming, which makes producing an overview difficult. However, advanced bibliometric mapping and clustering techniques can help visualize and structure complex research literature. Thus, the objective of this mapping study is to systematically explore and cluster the EE research literature to deliver a taxonomic scheme that can serve as a basis for future research. The analyzed data, which were drawn from the Web of Science and Scopus, consist of 1773 peer-reviewed documents published between 1975 and 2014. On the one hand, this taxonomy should create stronger ties to educational research; on the other, it can foster international research collaboration to boost both interdisciplinary EE and its impact on a global basis. This work reinforces our understanding of current EE research by identifying and distilling the most powerful intellectual relationships among its contributions and contributors. Consequently, this study addresses not only the academic community but also entrepreneurship educators and policymakers in an effort to boost entrepreneurial spirit, design effective policy instruments, and, ultimately, improve societal welfare.  相似文献
