This empirical study aims to determine whether online media coverage can be used to gather intelligence on specific crimes worldwide. The quality of online news is evaluated as an indicator of the worldwide distribution of jewelry store robberies. This phenomenon was selected because evaluating the risk of criminal events at the global level is a challenge for private companies, who need to settle and prioritize protection strategies to determine the actual risk within each country. Online media coverage is thus scrutinized for its ability to reveal spatiotemporal trends of this phenomenon. Based upon a dataset of online news gathered between 2015 and 2017 from the news aggregator website EMM (Europa Media Monitor – NewsBrief), the results show that online news may be a cost-effective method to analyze risks worldwide — though a cross-check with different data sources is still necessary to validate its accuracy. The developed approach shows that (1) while a multilingual approach is required, (2) cases can be detected and automatically classified with good accuracy; (3) moreover, dates and countries of published news articles are generally reliable indicators of the actual times and places of the events, which reduce the need for complex text analysis methods. This study demonstrates how a simple monitoring approach can be used to support the worldwide spatiotemporal analysis of serious crimes such as jewelry store robberies.

通过在线媒体报道的痕迹对犯罪进行全球分析:珠宝店抢劫案

这项实证研究旨在确定是否可以使用在线媒体报道来收集有关全球特定犯罪的情报。在线新闻的质量被评估为珠宝店抢劫案在全球范围内分布的指标。选择这种现象的原因是,在全球范围内评估犯罪事件的风险对私营公司构成了挑战,因为私营公司需要制定保护战略并确定其优先级,以确定每个国家的实际风险。因此,要仔细检查在线媒体的报道能力,以揭示这种现象的时空趋势。根据新闻聚合网站EMM(Europa Media Monitor – NewsBrief)收集的2015年至2017年在线新闻数据集,结果表明,在线新闻可能是一种分析全球风险的经济有效的方法,尽管仍然需要对不同数据源进行交叉检查以验证其准确性。改进的方法表明:(1)需要使用多语言方法时,(2)可以检测出案件并自动将其准确分类;(3)此外,已发布新闻的日期和国家通常是事件发生的实际时间和地点的可靠指标,从而减少了对复杂文本分析方法的需求。这项研究表明如何使用简单的监视方法来支持对严重犯罪(例如珠宝店抢劫)进行全球时空分析。(2)可以发现案件并自动将其准确分类;(3)此外,已发布新闻的日期和国家通常是事件发生的实际时间和地点的可靠指标,从而减少了对复杂文本分析方法的需求。这项研究表明如何使用简单的监视方法来支持对严重犯罪(例如珠宝店抢劫)进行全球时空分析。(2)可以发现案件并自动将其准确分类;(3)此外,已发布新闻的日期和国家通常是事件发生的实际时间和地点的可靠指标,从而减少了对复杂文本分析方法的需求。这项研究表明如何使用简单的监视方法来支持对严重犯罪(例如珠宝店抢劫)进行全球时空分析。
