Increasing the usefulness of archived crime data through the use of Data Visualization

Mr. Girendra Persaud, Mr. Troy Thomas, Dr. Troy Thomas
The use of data visualization has many benefits in the world of work. In many aspects of academic research, it can be noted that with social studies the data collected may be compounded with varying forms of data. These can range from social perceptions to social reactions. As such, many persons see the value in taking collected data, and representing it using graphical tools and aids. If these graphical tools and aids are applied in an effective manner, then the artifacts being presented are usually easily received by colleagues and or persons to whom the data is being presented to. Now with regards to the domain of public security, data on crime and demographics in a similar manner to social research is being collected and acted upon. But the issue lies in the way this data is stored and worked on. This data is processed and used by some The Ministry of Public Security in Guyana and The Guyana Police Force and their professionals have expressed frustration in the way this data is processed. Thus, since there is value in the application of advancing data visualization techniques, maybe then it can prove to be useful to those persons who truly need to use this crime data. This may help persons job to be easier, increase their productivity or even pick up more from the data in an easier fashion, than they could not have seen before. The purpose of this research is to show how the application of data visualization techniques can be of use, to those persons mentioned above whom actively use this collected crime data, and process it in a manual way. The results of this study indicate clearly that the use of data visualization can make crime data more useful and this was obtained through an evaluation of a system that was developed to help analyze crime data and highlight patterns in crime data.
