How math can help with forensics

Data mining, text mining and network association are all statistical tools that have come into their own as the shear quantity of available computational power increases. True, you do not need to have a strong basis in math to use these programs, but math can help determine where they may be used.

Text data mining takes the standard associative keyword based search techniques and increases their effectiveness through the ability to map associations with other words and to create visual representations of the data. This allows an investigator to drill down into previously undetermined associations and also allows the investigator to analyze immense amounts of data. One of the problems in the past has been in how to represent this data.

This is where visualisation technologies come to play. These allow the investigator to uncover previously hidden relationships in the data. More importantly, the visualisation techniques that are available today make the reporting
