Crime Topic Modeling
Objectives The classification of crime into discrete categories entails a massive loss of information. Crimes emerge out of a complex mix of behaviors and situations, yet most of these details cannot be captured by singular crime type labels. This information loss impacts our ability to not only understand the causes of crime, but also how to develop optimal crime prevention strategies. Methods...
متن کاملTopic Modeling and Classification of Cyberspace Papers Using Text Mining
The global cyberspace networks provide individuals with platforms to can interact, exchange ideas, share information, provide social support, conduct business, create artistic media, play games, engage in political discussions, and many more. The term cyberspace has become a conventional means to describe anything associated with the Internet and the diverse Internet culture. In fact, cyberspac...
متن کاملRebellion, crime and violence in Qing China, 1722–1911: A topic modeling approach
Banditry and unrest in eighteenth and nineteenth century China have attracted substantial attention from several generations of researchers. Often, they apply particular ontologies a priori to the source base. Given their reliance on state documents, these studies are subject to the perspectives of record-keepers and their theories of violence. It is particularly difficult to apply fixed defini...
متن کاملMemory-Efficient Topic Modeling
As one of the simplest probabilistic topic modeling techniques, latent Dirichlet allocation (LDA) has found many important applications in text mining, computer vision and computational biology. Recent training algorithms for LDA can be interpreted within a unified message passing framework. However, message passing requires storing previous messages with a large amount of memory space, increas...
متن کاملTowards Big Topic Modeling
To solve the big topic modeling problem, we need to reduce both time and space complexities of batch latent Dirichlet allocation (LDA) algorithms. Although parallel LDA algorithms on the multi-processor architecture have low time and space complexities, their communication costs among processors often scale linearly with the vocabulary size and the number of topics, leading to a serious scalabi...
