摘要: Cyber criminals exploit opportunities for anonymity and masquerade in web-based communication to conduct illegal activities such as phishing, spamming, cyber predation, threatening, blackmail, drug trafficking. One way fight crime is collect digital evidence from online documents prosecute the court of law. In this paper, we propose a unified framework using data mining natural language processing techniques analyze messages purpose investigation. Our takes chat log confiscated computer input, extracts social networks log, summarizes conversations into topics, identifies information relevant investigation, visualizes knowledge an investigator. To ensure that implemented meets needs law enforcement officers real-life closely collaborate with unit agency Canada. Both feedback experimental results suggest proposed effective
