Open government data (OGD) initiatives are an emergent platform research topic. There is little understanding how these platforms are governed for the innovation of services using open data, where the cultivation of an installed base of heterogeneous service innovators can lead to increased usage of OGD. In this paper, we draw on established literature from digital platforms research to investigate how service innovation is cultivated in open government data contexts. We employ a comparative case study of open government data platforms in three leading Latin American cities and draw upon the concept of boundary resources taken from platform theory. Our research generates two key contributions. First, we propose a theoretical model, which explains how an OGD platform owner is able to govern the demand and the supply side of its platform to facilitate the cultivation of a platform ecosystem. Second, we develop contributions to practice in terms of a set of recommendations for governments in emerging countries concerning how to establish and manage a vibrant OGD platform ecosystem. 相似文献

The rising number of data portals has been increasing demand for new techniques to assess data openness in an automated manner. Some methods have emerged that presuppose well-organized data catalogs, the availability of API interfaces and natively exposed metadata. However, many data portals, particularly those of local governments, appear to be misimplemented and developed with the classic website model in mind, which provides access to data only through user interaction with web forms. Data in such portals resides in the hidden part of the web, as it is dynamically produced only in response to direct requests. This paper proposes an automated method for assessing government-related data in the deep web on the basis of compliance with open data principles and requirements. To validate our method, we apply it in an experiment using the government websites of the 27 Brazilian capitals. The method is fully carried out for 22 of the capitals' websites, resulting in the analysis of 5.6 million government web pages. The results indicate that the keyword search approach utilized in the method, along with the checking of web pages for multifield web forms, is effective for identifying deep web data sources, as 1.5% of web pages with potential government data that are analyzed are found to contain data stored in the deep web. This work contributes to the development of a novel method that allows for the continuous checking and identification of government data from surface web data portals. In addition, this method can be scaled and repeated to assure the widest possible content coverage. 相似文献

The quality of metadata in open data portals plays a crucial role for the success of open data. E-government, for example, have to manage accurate and complete metadata information to guarantee the reliability and foster the reputation of e-government to the public. Measuring and comparing the quality of open data is not a straightforward process because it implies to take into consideration multiple quality dimensions whose quality may vary from one another, as well as various open data stakeholders who – depending on their role/needs – may have different preferences regarding the dimensions’ importance. To address this Multi-Criteria Decision Making (MCDM) problem, and since data quality is hardly considered in existing e-government models, this paper develops an Open Data Portal Quality (ODPQ) framework that enables end-users to easily and in real-time assess/rank open data portals. From a theoretical standpoint, the Analytic Hierarchy Process (AHP) is used to integrate various data quality dimensions and end-user preferences. From a practical standpoint, the proposed framework is used to compare over 250 open data portals, powered by organizations across 43 different countries. The findings of our study reveals that today’s organizations do not pay sufficient heed to the management of datasets, resources and associated metadata that they are currently publishing on their portal. 相似文献

This article provides an overview of open government data. It outlines what it is, provides examples, and summarizes library engagement with these data. The professional and academic literature and other web sources were examined along with government policies and portals. Open government data is a fairly recent and evolving phenomenon that promotes government transparency and invites citizen participation and innovative reuses of public data. Libraries have been responding to this release of data in a number of ways including offering data literacy instruction and special services and programs. 相似文献

This study investigates whether the platform used to deliver a tutorial matters in online information literacy instruction and assesses the overall quality of an information literacy tutorial assignment given to an undergraduate survey class. The study asks whether there is any pedagogical advantage between information literacy tutorials created in the LibGuides library guide creation software and tutorials created as Web pages. This research question is relevant to current studies of online information literacy tutorials, particularly given the increasingly dominant but under-researched position of LibGuides in the academic library world for delivering guides and tutorials. Two separate groups of students completed LibGuides and Web page versions of the same information literacy tutorial assignment in a university undergraduate communication course. Survey results of these 89 students indicated that both the LibGuides and Web page platforms deliver online instruction content effectively and achieve learning objectives almost equally well. Results also indicated content areas within the assignment that could be strengthened. 相似文献

For primarily undergraduate institutions, institutional repositories can become effective tools for communicating and showcasing faculty and student research, facilitating open access initiatives, or supporting new scholarly communication practices. Choosing the right software platform is crucial to the success of a repository initiative. The literature suggests that there are only two or three software platforms heavily used in undergraduate libraries. This article aims to give a landscape of the repository platforms used in sixty-seven undergraduate libraries in the United States in late 2013; it also includes the results of a short survey about current institutional repository software platforms and users/administrators’ satisfaction. 相似文献

ABSTRACT A data warehouse, developed for United States Department of Energy/National Nuclear Security Administration (USDOE/NNSA) Pantex Plant in a multi-department collaboration, brings data from disparate datasets and spatial information about the site together into a single database accessible through an intranet web page or ArcGIS software. The web page directs queries of buildings, facilities, and areas through a Geographic Information System (GIS) viewer that displays spatial site information and chemical hazards data. The Spatial Database Engine (ArcSDE) provides the vehicle for linking mainframe datasets, downloaded daily, to current spatial information about buildings and facilities that store chemicals of potential concern to firefighters and other emergency responders. The system is available to the plant's shift supervisors and individual GIS users throughout the department. 相似文献

针对数字平台在中国的迅速扩张,本文以阿里巴巴为例,反思西方平台化研究的局限,质询本土语境如何塑造了中国的平台化进程。以小资本主义为本土语境的切入点,本文搭建了一个集纳国家、中小企业、风险资本、平台运作机制的整合性框架,用以分析阿里巴巴的进化史。本文提出,阿里巴巴瞄准并利用了小资本主义传统中国家与中小企业的结构性张力,通过不断调整与国家、中小企业、风险资本、平台机制的关系实现了平台扩张。强调语境化、历史化和多元力量的整合性框架打破了西方平台研究的标准叙事,为平台研究提供了新的思路。 相似文献
