中文简介:

我们介绍了城市数据管道-一种收集以开放数据形式发布的城市绩效指标的系统,以简化西门子内部使用的研究和报告的汇编。在开放数据为自动化繁琐的数据研究任务提供手段的假设下,我们构建了一个系统,该系统集成了来自各种开放数据源的城市基本指标。该体系结构灵活,可扩展,并且原生基于RDF和SPARQL。我们报告了挑战(数据质量,覆盖范围,异构性),开放数据在整个行业的可用性以及我们为克服其中一些相关问题而开展的研究。

课程简介: We present the City Data Pipeline – a system for gathering city performance indicators published as Open Data in order to ease the compilation of studies and reports used within Siemens. Under the assumption that Open Data provides means to automatise tedious data research tasks, we have built a system that integrates basic indicators for cities from various Open Data sources. The architecture is flexible, extensible, and natively based on RDF & SPARQL. We report on challenges (data quality, coverage, heterogeneity), on the usability of Open Data for industry in general, and our research to overcome some of the involved issues.
