Indiana University-Purdue University Indianapolis (IUPUI) / Increasing rates of social harm events and plethora of text data demands the need of employing text mining techniques not only to better understand their causes but also to develop optimal prevention strategies. In this work, we study three social harm issues: crime topic models, transitions into drug addiction and homicide investigation chronologies. Topic modeling for the categorization and analysis of crime report text allows for more nuanced categories of crime compared to official UCR categorizations. This study has important implications in hotspot policing. We investigate the extent to which topic models that improve coherence lead to higher levels of crime concentration. We further explore the transitions into drug addiction using Reddit data. We proposed a prediction model to classify the users’ transition from casual drug discussion forum to recovery drug discussion forum and the likelihood of such transitions. Through this study we offer insights into modern drug culture and provide tools with potential applications in combating opioid crises. Lastly, we present a knowledge graph based framework for homicide investigation chronologies that may aid investigators in analyzing homicide case data and also allow for post hoc analysis of key features that determine whether a homicide is ultimately solved. For this purpose we perform named entity recognition to determine witnesses, detectives and suspects from chronology, use keyword expansion to identify various evidence types and finally link these entities and evidence to construct a homicide investigation knowledge graph. We compare the performance over several choice of methodologies for these sub-tasks and analyze the association between network statistics of knowledge graph and homicide solvability.

A presente pesquisa, valendo-se do método de pesquisa-ação, objetiva propor ações que possam ser implementadas para a melhora na eficácia da investigação de homicídios na cidade de Curitiba, atualmente realizada pela Divisão de Homicídios e Proteção à Pessoa (DHPP-PR). Para tanto se realizou pesquisa bibliográfica e de campo nas divisionais de homicídio de São Paulo e Curitiba. Dissertou-se acerca da relação do Estado, governo e administração pública com a segurança pública; sobre as noções históricas da polícia de segurança, com sua definição. Apresentou-se a taxionomia das diversas polícias atuantes no Brasil. Discorreu-se sobre o conceito de violência e constatou-se seu espraiamento para regiões antes mais seguras. Por fim, verificaram-se as práticas da Departamento Estadual de Homicídios e de Proteção à Pessoa (DHPP-SP) e as melhores ações, comparando-as às práticas da DHPP-PR de Curitiba, apontando os problemas identificados e propondo ações passíveis de solucioná-los. / This research, taking advantage of the method of research-action aims to propose actions that can be implemented to improve the effectiveness of the investigation of homicides in the city of Curitiba, currently held by Homicide Division and Protection of Persons (DHPP-PR). Held bibliographic and field research in the divisional murder of São Paulo and Curitiba. Disserted on the relationship of the state, government and public administration to public security; on the historical notions of security police with their definition. Presented the taxonomy of the various active security police in Brazil. Discoursed about the concept of violence and found out before its spreading to safer areas. Finally, there were the practices of the State Department of Homicide and Protection of Persons (DHPP-SP) and its best actions, comparing them to the practices of DHPP-PR from Curitiba, pointing out the problems identified and proposing actions that could solve them.
