Identifying Victims of Human Sex Trafficking in Online Ads

Social media and the interactive web have enabled human traffickers to lure victims and then sell them faster and in greater safety than ever before. However, these same tools have also enabled investigators in their search for victims and criminals. A prototype was designed to identify victims of human sex trafficking by analyzing online ads. The prototype used a knowledge management to generate actionable intelligence by applying a set of strong filters based on an ontology to identify potential victims. The prototype was used to analyze data sets generated from online ads. An unexpected outcome of the second data set was the discovery of the use of emojis in an expanded ontology. The final prototype used the expanded ontology to identify potential victims. The results of applying the prototypes suggest a viable approach to identifying victims of human sex trafficking in online ads.
