ABSTRACT

With the advent of more law enforcement open data, researchers are exploring the use of calls for service (CFS) as a proxy for recorded incident information by law enforcement. However, indications are that law enforcement activities are mediated by the agency’s goals with its data. Using data from two different types of law enforcement agencies within the same community, CFS and incident reports for property crimes were tested for spatial association using the co-location quotient. Findings from this study show there is a modest amount of detectable clustering of CFS for the municipal law enforcement agency. However, the large university campus agency did not show any detectable spatial association for these events. This suggests that the movement towards using open data in research will need to take greater care in the selection of data to understand if assumptions about the data can be supported.

摘要

随着更多执法开放数据的出现，研究人员正在探索使用呼叫服务 (CFS) 作为执法记录事件信息的代理。然而，有迹象表明执法活动是由该机构的目标及其数据所调节的。使用来自同一社区内两种不同类型的执法机构的数据，CFS 和财产犯罪事件报告使用协同定位商进行空间关联测试。这项研究的结果表明，对于市政执法机构而言，可检测到的 CFS 集群数量适中。然而，大型大学校园机构并没有显示出这些事件的任何可检测到的空间关联。
