[目的/意义] 在数据驱动范式情境下，揭示政府门户网站开放数据状态及其主体行为状态之间的内部关联，推动政府数据开放效果和进程。[方法/过程] 采用爬虫方法抓取上海市政府数据门户网站中各开放数据集，在对各数据集指标进行相关分析的基础上，采用Stepwise探索其回归关系，筛选得出关联度较高的变量；进一步对关系显著的变量进行PLS回归检验，得出政府开放数据状态与其主体行为状态的内部关联。[结果/结论] 在政府数据开放进程中，政府部门的主体行为比数据自身的客体特征对公众主体行为的影响更大。在影响公众评分的因素中，政府开放保密级别的影响因子最大，且具有显著负向影响作用；政府更新频率、政府首次开放时间、数据格式可机读性对公众评分具有显著正向影响作用。 相似文献

Current publishing practices in academia tend to result in datasets that are difficult to discover. This is because datasets are not well-integrated across academic domains and they are often not linked to the documents that reference them. For these reasons, discovering datasets across domains can be challenging; for example, discovering archeological observations and biological specimens using the same search is not widely supported, even if both datasets share a similar spatial extent, like Mesoamerica. It is also challenging to retrieve relevant documents that reference datasets; for example, retrieving a series of field reports that reference archeological observations is typically not supported. Our work develops an extensible method for: (1) geographically integrating collections across disciplinary repositories and (2) connecting datasets to related documents. We describe a collection of spatially-referenced researcher datasets, capturing their metadata elements and encoding them as linked open data. We then leverage existing library services to formalize links from datasets to documents. The system described in this work has been deployed, resulting in an experimental open data site for the UCSB campus. Results indicate that this system can be scaled-up with support from an institutional repository in the near future. 相似文献

The Ontario Council of University Libraries (OCUL) is a consortium of the twenty-one university libraries in Ontario, Canada. Since 1967, OCUL member institutions have worked together to share costs and workload through collective purchasing and licensing of information resources and more recently through the establishment of a shared digital infrastructure known as Scholars Portal. Under the auspices of OCUL, Ontario's university map librarians formed the OCUL Map Group in 1973 to seek opportunities to communicate and collaborate to improve the collections and services they offer their users. The opportunities provided by collaboration have ensured a greater capacity to manage evolving collections of geospatial data. The group has served as a community of practice, which has provided educational opportunities and facilitated collaborative problem solving through a listserv, conference calls, and face-to-face meetings. This collegial environment has also led to the completion of a number of projects, which have resulted in the creation of new technical infrastructures and strategies for sharing the workload of data management tasks. This paper discusses the role of collaboration in OCUL projects and offers some suggestions for others considering embarking on collaborations of their own. 相似文献

讨论集群知识创新研究是集群知识系统研究的重要组成部分,而集群中的知识创新活动总是在一定的认知共同体中进行的。分析认知共同体的自组织特征,提出认知共同体的涌现过程就是互等结构的形成过程,并分析知识门户设计对认知共同体涌现机制的影响,并对认知共同体的进化过程进行分析,这对认识集群中的知识共享及创新活动具有重要意义。 相似文献

ABSTRACTIt has become difficult to evaluate and gauge the extent of the ever-expanding Czech literary web. This article focuses on analyzing the current status of the Czech literary web and associated online repositories. For purposes of this article, the author examined twenty open access Czech sites whose subject matter is Czech literature. Out of these twenty websites, the author analyzed five sites in great detail. The data for the analysis was extracted initially in December of 2014. 相似文献

Leslie Weir talks about her career in librarianship, librarianship in general, and the development and governance of consortia, portals, digital initiatives, and open access in Canada. She discusses, among other things, CARL, Scholars Portal, OCUL-IR, CRKN, and Canadiana.org. in light of access to electronic resources. 相似文献

Abstract With the transformation of the card catalog into the online public access catalog came the expectation of its increased functionality. For the most part, today's online catalogs perform an expanded list of tasks quite effectively. Bibliographic utilities, system vendors, and individual libraries continue to improve bibliographic retrieval by providing new and better services through the catalog. In spite of these improvements, many observers believe that online catalogs have reached their maturity. Today's information environment includes a wealth of material to which online catalogs cannot provide universal and up-to-date access. Increasingly, librarians are turning to federated searching portal applications to find a means of managing the flood of digital information that threatens to engulf users. This chapter describes essential functionality of such tools, suggesting directions and strategies for improving them. The author concludes that, while the online catalog will continue to function as the principal tool for access control of the library's physical collections, the federated searching portal will ultimately serve as the library's principal Web gateway to digital resources. 相似文献

Students and parents rely on Web-based tools to navigate the college-choice process, yet little research has been done to understand this environment. While this shift has made the process easier to navigate for some, we contend that the move will grow an already large digital divide in the USA. We use Hossler and Gallagher's college-choice framework to examine the substance and function of three college-access Web portals. Our findings suggest these tools are likely to serve many students well in the process, but may exacerbate the digital divide with consequences for low-income students. 相似文献
