Inference of the Russian drug community from one of the largest social networks in the Russian Federation

Abstract

The criminal nature of narcotics complicates the direct assessment of a drug community, while having a good understanding of the type of people drawn or currently using drugs is vital for finding effective intervening strategies. Especially for the Russian Federation this is of immediate concern given the dramatic increase it has seen in drug abuse since the fall of the Soviet Union in the early nineties. Using unique data from the Russian social network 'LiveJournal' with over 39 million registered users worldwide, we were able for the first time to identify the on-line drug community by context sensitive text mining of the users' blogs using a dictionary of known drug-related official and 'slang' terminology. By comparing the interests of the users that most actively spread information on narcotics over the network with the interests of the individuals outside the on-line drug community, we found that the 'average' drug user in the Russian L.J. Dijkstra and A.V. Yakushev share first authorship of this work.

The Relative Ineffectiveness of Criminal Network Disruption

“…Combining multiple sources of data on criminal cooperation seems to be essential in confining these data validity problems. The importance of a ‘no boundary’ intelligence gathering strategy, was also one of the results of a recent study by Dijkstra et al68 that show how a dark population of susceptible and infected drug users in Russia can be identified on the basis of social media information. This strategy opens the door for actually seeking rather than assuming criminal network structure7.…”

“…Text mining can be applied in many ways; for example, it was also used to track down criminals and terrorists by analyzing past criminal records and applying the results to similar types of crimes [53]. In addition, the frequencies of search words in search engines were used to predict outbreak trends of diseases.…”
