A survey on Datamining in Cyber Bullying

CRIME has always the very first thing that people want to avoid and police officer want to stop. A major challenge facing all lawenforcement and intelligence –gathering organizations is accurately and efficiently analyzing the growing volumes of crime data. Crime activity reports available from victims, governmental organizations, news press, and social networks play a significant role in public safety, including crime prevention, suppression and investigation, uniformed patrol and response. Cyber Crime is an area which covers crimes committed in the internet. Opportunities for connecting with classmates, friends and people with shared interests abound. Email, online chat, and social networking sites allow us to interact with people in the same town and people on the other side of the world. Unfortunately the opportunity for misuse comes with any new technology. There were sexual predators and bullies long before the advent of the internet and chat rooms. Cyber bullying and internet predation threaten minors, particular teens and teens who do not have adequate supervision when they use the computer. As the amount of criminal records growing every day, it is impossible to perform manual analysis on the dataset and extract useful information. Data mining has been studying for decades trying to get useful information out of large amount of data. Many efforts have used automated techniques to analyze different types of crimes, but without a unifying framework describing how to apply them. In particular, understanding the relationship between analysis capability and crime type characteristics can help investigators more effectively use those techniques to identify trends and patterns, address problem areas and even predict crimes.
