众包意味着用户的协作和参与，这促进了城市治理进程的更新。在这篇文章中，我们解决了一个子集的众包，名为公民采购，公民与当局合作，积极互动。许多系统在城市治理过程中尝试了公民采购;然而，它们的成熟度参差不齐。为了关注服务成熟度，我们引入了一个城市服务成熟度框架，它包含五个层次的服务支持和两个层次的信息集成。作为一个例子，我们介绍了城市饲料，它实现了市民采购的城市问题管理过程。为了支持这样的过程，CITY FEED支持成熟度框架的所有级别（发布、交易、交互、协作和评估），并以相关和异构的方式集成相关信息。为了整合异构信息，它实现了一个三重的饲料去重机制的基础上的地理，文本语义和图像的饲料相似性。目前，CITY FEED正处于试点阶段。
Crowdsourcing implies user collaboration and engagement, which fosters a renewal of city governance processes. In this article, we address a subset of crowdsourcing, named citizen-sourcing, where citizens interact with authorities collaboratively and actively. Many systems have experimented citizen-sourcing in city governance processes; however, their maturity levels are mixed. In order to focus on the service maturity, we introduce a city service maturity framework that contains five levels of service support and two levels of information integration. As an example, we introduce CITY FEED, which implements citizen-sourcing in city issue management process. In order to support such process, CITY FEED supports all levels of the maturity framework (publishing, transacting, interacting, collaborating, and evaluating) and integrates related information relationally and heterogeneously. In order to integrate heterogeneous information, it implements a threefold feed deduplication mechanism based on the geographic, text semantic, and image similarities of feeds. Currently, CITY FEED is in a pilot stage.
