Summing Up

Data mining is the process of analyzing data from different perspectives and summarizing it into useful information. A crime analyst, using data mining, can extract useful information from very large and complex data sets. In Chapter 10, we further explore practical intelligence applications.

Questions for Discussion

  • 1. What might be some new and unique applications of data mining in police work?
  • 2. What might be some of the challenges of data mining for the intelligence analyst?
