BI Presentation
Objective• The motivation behind this project is to come up with
effective data management to help curb violent crime in the city of St. Louis.
Demonstrating• Data sources used • Data maintained • Use case examples for Management, Police Department,
and Patrol Officers • Finally overview of the BI system’s added value
Scope of Project
Users:• St. Louis Police Department•Captains and Managers• Lieutenants and Detectives• Patrol Officers
Value provided: •We hope that this project will support the decision making process of the St. Louis police department on their mission to curb homicides in St. Louis city.
Scope of Project
Examples of the support for decision making include:•How to strategically place their man power•Where to deploy patrol, mounted, or bike officers• Patrolling frequencies (differs according to the area)•Determine trends in criminal activity; likelihood of time and location
• Increased use of social media data to locate crime hot spots• Track unfolding events in real-time; be informed of large, disruptive crowds or planned gatherings that could turn violent
Scope of Project
U.S. Census Data
• American Community Survey
• Decennial Census
Twitter & Social Media
Historical Crime Data
• FBI Crime Statistics
• STLPD Data
Data variables being maintained
• Mean Household income
• Education level
• Home Vacancy rates rented / owned
• Unemployment rate
• Data aggregated by district to neighborhood
Data Sources
Historical Crime Data• Data is entered as calls
come in• Tracks location, crime, and
time• Can flag similar crimes,
e.g., vehicle or weapon used
Census Data• Loaded as it is released to
build a demographic model of the neighborhood
Twitter & Social Media• Monitored Real-time for
Keywords• Mines text for location, can
display potential trouble spots before any 911 calls are made
Maintaining Data
System Structure
• System can be hosted
externally or
maintained in-house
• Based on STLPD
requirements,
hardware can be
cloud-sourced or
maintained in-house
Decision-makers can view historical trends in crime for all of St. Louis• High-level summary• Can view time-specific
events; festivals, parades, etc.• Can drill-down and view
current resources assigned to specific neighborhoods
Use Case: Management
Petty Larceny Complaints – Week Ending 04/27/2013
Summary of a small geographic area – useful in determining local hot spots and trends• Past crime trends• Can view crimes that are
similar• Can see where patrol
officers are assigned
Use Case: Neighborhood Office
Departure from Mean: Complaints a Year Ago
+10%
0%
-10%
Displaying: Homicides

• Supports near real-time analysis of crime• Not real-time; not all data can be maintained in real-time due to
difficulty in collecting the information
• Predictive capabilities are near-future• Can analyze weeks to a few months into the future, not years
• On-going maintenance and support will include a cost• Support and IT Personnel
• Training for Users
• Investment in hardware (outsourced or internal)
System Constraints
Overview• As BI consultants to the City of St. Louis Police Department we
conclude our presentation by discussing the following.
• In an effort to better facilitate the Police Department’s decision making processes, we proposed a BI system using available and easily-maintained data
• The BI dashboard developed by Group A has provides support to different levels of decision-makers in the STLPD
• The BI system provides increased responsiveness to crime trends, assists in optimizing the deployment of limited departmental resources, and supports analysis of different policing strategies
