‘liv­ing thing’ must be fed data

Kent Messenger Maidstone - - FRONT PAGE -

As the tech­nol­ogy gets more so­phis­ti­cated, of­fi­cers can make sure they are in an area be­fore some­thing has even oc­curred, their pres­ence alone stop­ping even the most brazen crim­i­nal from strik­ing.

PredPol uses three data points; past type, place and time of crime, to cre­ate a unique al­go­rithm based on crim­i­nal be­hav­iour pat­terns.

The PredPol soft­ware al­lows po­lice forces across the world to tai­lor their sys­tem to their lo­ca­tion.

When Kent Po­lice be­gan its pre­dic­tive polic­ing pi­lot in De­cem­ber 2012, it started by feed­ing data, in­clud­ing five years’ worth of recorded crimes and three years of in­ci­dents of an­ti­so­cial be­hav­iour, into a com­puter.

Mark John­son calls the PredPol pro­gramme akin to a “liv­ing thing” in that it must con­stantly be fed new in­for­ma­tion to keep be­ing able to ac­cu­rately pre­dict where crimes will hap­pen.

Kent’s PredPol sys­tem costs the equiv­a­lent of about two po­lice of­fi­cers per year.

It is suc­cess­ful in pre­dict­ing “space-de­pen­dent” crimes like anti-so­cial be­hav­iour.
