虽然从自愿提供的地理信息中获得的数据与公共调查有本质的不同，但数据的数量庞大，数据的质量往往很差。为了提高VGI数据的质量，参与区域数据生成的用户数量的位置准确性和多样性以及相互作用是重要的。本研究提出了一种新的方法来积累的开放街道地图（OSM）的数据，使用OSM Notes，并试图分析的地理分布和贡献的内容的特点，定量和定性。随后，结果显示了OSM说明中的区域差异，但它使用户了解了OSM质量管理的新特征，即使在OSM活动不一定活跃的区域。此外，还可以发现新的因素，如匿名用户更正和贡献所需的时间过渡。这些结果预计将作为一种工具，用户相互沟通，以解决数据错误，存在于OSM和提供未来的研究人员与全球OSM活动中的用户交互的例子。
Although the data obtained from volunteered geographic information (VGI) are inherently different from public surveys, the quantity of the data are vast and the quality of the data are often poor. To improve the quality of VGI data, the positional accuracy and diversity and interaction of the number of users involved in the regional generation of the data are important. This research proposes a new approach for the accumulation of OpenStreetMap (OSM) data by using OSM Notes and attempts to analyze the geographical distribution and the characteristics of the contents of the contributions, quantitatively and qualitatively. Subsequently, the results demonstrated regional differences in OSM Notes, but it provided users with an understanding of the new features of quality management in OSM, even in regions where OSM activities are not necessarily active. In addition, it was also possible to discover new factors such as the time transition required for the correction and contribution of anonymous users. These results are expected to serve as a tool for users to communicate with each other to resolve data bugs that exist in OSM and provide future researchers with examples of user interaction in global OSM activities.
