Digital forensic investigation using subject-based semantic document processing

Abstract

Digital Forensic is a branch of Forensic science that encompasses the recovery and investigation of digital devices for material mainly related to computer crime. Digital Forensic Investigation is the process of investigating digital devices for the purpose of generating digital evidence related to an incident or a crime under investigation. A proliferation in the amount of crimes and crime related data has lead to a demand in digital forensic investigation tools that helps the investigator to detect, analyze and investigate the criminal data stored on digital devices. This system introduces a subject-based semantic approach that retrieves a set of top documents that are semantically related to each other corresponding to the subject defined by the investigator.
