Mapping of the Perception of Theft Crimes from Analysis of Newspaper Articles Online

摘要

The analysis of crimes represents a great challenge to law enforcement agencies and organizations that collect information to analyze accurately and effectively the distribution of the behavior of criminal events, considering that the sources to be used in the process of generating intelligence are diverse in content and/or structure. Tools that have contributed to the analysis of fields in which massive amounts of data are available is ʺdata miningʺ, a powerful tool that can be used effectively in the analysis of large amounts of data and in the subsequent derivation of important analytical results. This paper presents a methodology of analysis of crime facts from online newspapers, identifying the different communes where the greatest number of criminal events occur, which gives an idea of potentially more dangerous places, through the detection and geographical mapping of critical points, or the analysis of the nature of the crime through the extraction of entities. Statistics that measure the predictive capacity of the model indicate that the methodology is robust to recognize crime events within the body of the news.
