基于"人-地-网"关系的网络空间要素层次体系建设 总被引：1，自引：0，他引：1
网络空间具有高度复杂性,与地理空间交织融合,共同构成人类的活动空间。构建主题完整、层次清晰的网络空间要素层次体系,是绘制网络空间地理图谱、实现网络空间可视化表达的重要基础。本文以网络空间地理学理论为指导,紧密围绕“人-地-网”纽带关系,结合网络安全工作的实战需求,借鉴地理要素指标体系构建方式,提出了包含地理环境层、网络环境层、行为主体层和业务环境层的四层网络空间层次模型,阐述了各层次要素的表达方法与关联途径,以服务于网络资产管理和网络安全防控等业务需求。 相似文献

This paper revisits the death of distance hypothesis. To explore the role of distance in the information age, three methods – web scan, hyperlink, and trace-route – are used to map the Internet for the US educational network. Statistical analysis is conducted to evaluate whether physical distance has any impact on the Internet information access. The cartographic and statistical results indicate that geography in general and distance in particular are still important factors in shaping the spatial pattern of Internet activities. For the most popular fifty-three US educational web sites, the physical distance within one thousand miles has positive effects on Internet access while access to international hosts heavily depends on the response time, link speed and other Internet infrastructures and interconnections such as the availability of domain name servers, network access points, backbones, etc. Implications of absolute, relative, and virtual distance in mapping the Internet are discussed. It is concluded that the death of distance hypothesis is premature, even misguided in most cases. 相似文献

This paper counters the notion that cyberspace is a placeless electronic sphere through an analysis of British children's use of the Internet. It demonstrates that rather than being accessible from everywhere but existing nowhere, cyberspace is shaped through place-routed cultures, and in particular through processes of Americanization. 相似文献

ABSTRACT. As an information economy and a cultural hallmark, cyberspace belies traditional boundaries yet involves a distinctive territory, citizenry, literature, technology, capital and finance, ritual, weapons and belligerencies, a recognizable past, and variegated if unspecified futures. Not easily quantified is the geography of so elusive and placeless an entity, and its technology has been variously portrayed as utopian, liberating, elitist, or enslaving; in it are brought to life strains of technological determinism. Maps of cyberspace can be forged only with utmost difficulty, and it is best beloved and imagined in dense cyberpunk fiction. Part sacred space, part ethereal region, part digital fact, cyberspace involves a regional geography perhaps best captured in a koan: What is the place where everyone is but nobody lives? 相似文献

大众文化语境下的网络媒介以其虚拟、自由、平等和娱乐特性为置身于赛博空间"狂欢节广场"的网民提供了体验新的愉悦生活的条件。网民们利用匿名优势、以自娱性姿态挣脱了语言规范的羁绊,恣意表达个性。由此,赛博空间话语狂欢。网络语词的使用背离常规,发生变异,其特征有四:缩略语词的编码呈任意性、图符语词成为非语言交际的语符形式、谐音语词唯"读出"方能会意以及编码语词的所指与能指相互矛盾。 相似文献

The worldwide surge of the location-based game Pokémon Go since mid-2016 has raised debates among online gaming communities and the general public on the unique phenomenon of location spoofing. Location spoofing enables gamers to engage in remote activities by using simulated locational information. This has been largely considered a threat to the underlying fairness of the game and thus to the social order of both online game communities and the real world. This article takes up location spoofing as a unique case to engage the spatial data quality issue, an ever more fundamentally important issue in geography in today’s era of big data. Unlike the well-examined systematic error, outliers, and uncertainty in spatial data, our understanding of user-generated spatial data from location spoofing is rather limited. To fill this gap and advance the debates on the spatial data quality issue, we collected a data set of Pokémon and applied actor–network theory to examine the various human and nonhuman agents involved, including gamers, spoofers, game developers, bots, and hackers. We argue that location spoofing in mobile games and other increasingly location-based services (e.g., Uber) should not be merely interpreted as fake data but should be taken seriously as real human geographic data in new spatial (re)assemblages proliferating nowadays. We encourage scholars in geography and neighboring fields to investigate this emerging issue in location-based services, with the goal of promoting a more critical and holistic understanding of geospatial big data. 相似文献

Community networks help build place-based community by offering individual citizens and organizations access to the Internet, the ability to post information online, and opportunities to discuss community affairs. Community networks are inspired by a dynamic vision of community that incorporates a global sense of place. A global sense of place is valuable because it helps to illuminate a place's connections with the world and may therefore enable scale-jumping forms of activism. This article analyzes interviews with participants in four U.S. community networks to explore how networks combine a politics of mobility, a politics of access, and a politics of place to construct a global sense of place. The degree to which each network emphasizes mobility, access, and place varies. This variation has implications for both community activism and issues of diversity in community. Networks that fail to link mobility, access, and place may increase, rather than decrease, inequalities in access to electronic communications as well as to forms of political power. 相似文献

网络空间信息可视化对揭示网络空域规律、促进网络空间认知具有重要意义。将网络空间节点与拓扑关系直接可视化的视图中存在大量的点重合和线交叉,目前已有的网络节点布局算法、集束边技术、骨干网提取和网络路由拓扑多尺度表达等方法能够优化视图效果,但在网络的微观结构上,对保持网络空间点群要素的特征信息关注不够。通过分析并量化网络空间点群要素的各类特征信息,提出了一种基于层次聚类的要素聚合方法和一种基于节点重要性度量的要素选取方法,以自动综合的方式对网络空间点群要素进行综合。实验结果表明,该方法能够保持网络空间点群要素的空间特征,为定量表达网络空间特征、加速生成视觉效果良好的网络空间地图提供基础数据综合方法。 相似文献

Abstract This article identifies teaching strategies to explore cultural universals. Traits that contribute to distinguishing one culture from another can be classified into general categories that all cultures share. Students identify universals in their daily lives and then compare and contrast different cultural perspectives through an exploration of these universals. Computer technology provides access to images and information about other cultures that might be used to increase students' understanding of cultural perspectives. The Internet provides a vehicle for classrooms to exchange cooperative creative writing stories that allow students the opportunity to explore different cultural perspectives through the eyes of other students around the world. Suggestions about how to establish and conduct a classroom exchange project over the Internet are provided. 相似文献
