Designing and Implementing a Model to Identify Cyberbullying in Facebook
Problem and Contributions• Cyberbullying is the use of online digital media to
communicate false, embarrassing, or hostileinformation about another person.
• It is the most common online risk for adolescents andwell over half of young people do not tell theirparents when it occurs.
• There have been many studies about the nature andprevalence of cyberbullying.
• Relatively less work in the area of automatedidentification of cyberbullying.
• The focus of our work is to develop an automatedmodel to identify and measure the degree ofcyberbullying in social networking sites.
• We present the design of a model for identifyingcyberbullying that builds on previous researchfindings in the areas of traditional bullying andcyberbullying in adolescents.
• We also identify challenges and opportunities tointegrate the latest results from psychology andsocial network data analysis to address a problem ofgreat social impact.
Design• BullyBlocker analyzes adolescents’ interactions with
their social network to identify:• Warning signs: e.g., number of insulting messages
and embarrassing pictures.• States of vulnerability: e.g., newcomers, age-gender
group, members of minority groups, people withdisabilities, etc.
• The integration of these factors is guided by previousresearch results in psychology.
• Bullying Rank: Estimates the probability of a minorexperiencing cyberbullying.
• The computed Bullying Rank is returned to the parentor guardian of the minor.
• The Bullying Rank Is divided into three normalizedlevels of risk intensity: Low[0-33], Medium[34-66],High[67-100]
