In our times, a growing interest of organizations, including also the public ones, in crowdsourcing, can be observed. It enables to acquire knowledge located in virtual communities. However, despite many benefits, crowdsourcing initiatives very often fail. Therefore, a need for their evaluation is recognized. Nonetheless, in the subject literature, a shortfall of criteria and methods of evaluating crowdsourcing may be observed. The existing proposals do not ensure a comprehensive picture of crowdsourcing, and they do not take into account its multidimensionality. The article is intended for a presentation of the ways of evaluating crowdsourcing and an original proposal of a list of indicators, which may be used for evaluating crowdsourcing in public organizations. The article presents the original proposal of activities, by which it is possible to assess the degree of implementation of the adopted tasks and determine the level of obtained crowdsourcing results. The conducted research allowed to recognize that it is possible to measure crowdsourcing results using quantitative and qualitative indicators. A prerequisite for selecting the appropriate means is first of all to indicate the purposes for which crowdsourcing should be used.

众包的理论和方法论方面：有效性及其度量

在我们这个时代，可以观察到组织（包括公共组织）对众包的兴趣与日俱增。它可以获取位于虚拟社区中的知识。然而，尽管有很多好处，众包计划经常失败。因此，认识到需要对其进行评估。但是，在主题文献中，可能会发现评估众包的标准和方法不足。现有的提议不能确保对众包的全面了解，也没有考虑到它的多维性。本文旨在介绍评估众包的方式，并提出一系列指标的原始建议，这些指标可用于评估公共组织中的众包。本文介绍了活动的原始建议，通过它可以评估所执行任务的执行程度，并确定获得的众包结果的水平。进行的研究使人们认识到可以使用定量和定性指标来衡量众包结果。选择适当手段的先决条件是首先指出应使用众包的目的。
