Summary
"A method of data mining regular police records to identify possible criminal organizations has been developed. Between 2001 and 2006, offending related to 236 possible criminal organizations was reported to RCMP "E" Division, with 39 of the groups being particularly serious. This study combined computational mathematical analysis, social network analysis methods, and data mining techniques in a unique way to automatically identify traces of possible criminal organizations in operational police records."--Executive summary.
