Characteristics of a Sexual Predator

AbstractThis paper presents a system developed for detecting sexual predators in online chat conversations using a two-stage classification and behavioral features. A sexual predator is defined as a person who tries to obtain sexual favors in a predatory manner, usually with underage people. The proposed approach uses several text categorization methods and empirical behavioral features developed especially for the task at hand. After investigating various approaches for solving the sexual predator identification problem, we have found that a two-stage classifier achieves the best results. In the first stage, we employ a Support Vector Machine classifier to distinguish conversations having suspicious content from safe online discussions. This is useful as most chat conversations in real life do not contain a sexual predator, therefore it can be viewed as a filtering phase that enables the actual detection of predators to be done only for suspicious chats that contain a sexual predator with a very high degree. In the second stage, we detect which of the users in a suspicious discussion is an actual predator using a Random Forest classifier. The system was tested on the corpus provided by the PAN 2012 workshop organizers and the results are encouraging because, as far as we know, our solution outperforms all previous approaches developed for solving this task.

The Dominion Post editor Tim Pankhurst, whose newspaper celebrated its centenary in 2007, outlines the innovations undertaken by his newspaper in meeting the technological challenges of the mainstream media. "Opposite is the by now familiar face of former assistant police commissioner and former Auckland district commander Clint Rickards. He resigned in disgrace in Decemeber 2007 the day before internal police disciplinary charges were to begin against him. He had survived two rape trials and escaped being convicted of any criminal offence but there was no doubt he had brought the police into disrepute through his actions in Rotorua in the 1980s, when he admitted to engaging in group sex while on duty. At the very elast he was a sexual predator and a highly intimidating bully..."

Sexual Transgression

A close reading of the Uttarakāṇḍa of Vālmīki’s Rāmāyaṇa demonstrates that its author has composed a carefully and logically structured work, one that is haunted by themes of sexual transgression. Not only is the first half of the kāṇḍa occupied with the history and genealogy of Rāvaṇa, who is no less than the sexual predator par excellence, but its latter half tells of Rāma’s seemingly heart-wrenching decision to banish Sītā based on rumours of her own supposed infidelity. Similar themes are reflected in a number of the kāṇḍa’s sub-stories—both those that are understood to be part of the main narrative and those that belong to the so-called ‘purāṇic’ narratives—and highlight sexual aggression against women. This article examines a specific and unusual subset of such narratives that permeate the kāṇḍa, those that deal with explicit rape, with an eye towards further understanding why, uniquely in this kāṇḍa, such stories appear, and what lies behind their popularity and longevity.
