Detecting sexually predatory content in an electronic communication

A system for detecting an electronic communication sent or received by a minor including sexual predatory behavior, comprising:

• a computer to receive or send the electronic communication;
• computer-executable instructions to specify a type of the sexual predatory behavior to detect whether the electronic communication relates to said type of the sexual predatory behavior wherein said type of the sexual predatory behavior includes one or more of the following:
• bullying behavior, offensive language, personal information solicitation or revelation, personal characteristics solicitation or revelation, meeting arrangement with a stranger, picture sharing with a stranger, or a combination thereof;
• computer-executable instructions to analyze one or more features of the electronic communication, said one or more features indicative of the sexual predatory behavior wherein the computer-executable instructions to analyze one or more features of the electronic communication further comprise computer-executable instructions to:
• parse the electronic communication to generate a plurality of constituent tokens of the electronic communication;
• generate, in response to said tokens, a feature vector associated with the electronic communication, said feature vector indicating whether each one of a predefined set of one or more features relating to the type of the sexual predatory behavior is present in the electronic communication;
• and
• apply the generated feature vector to a probabilistic classifier relating to the type of the sexual predatory behavior to generate a rating for the electronic communication, wherein the probabilistic classifier trained on a content, anti-content, and close anti-content of the type of the sexual predatory behavior to identify said predefined set of one or more features, said rating indicating a probability that the electronic communication relates to the type of the sexual predatory behavior;
• computer-executable instructions to categorize the electronic communication as either relating to the sexual predatory behavior or relating to an innocuous behavior as a function of the analyzed features rating;
• computer-executable instructions to generate a report if the electronic communication is categorized as relating to the sexual predatory behavior, said report indicative of the sexual predatory behavior;
• and
• computer-executable instructions to send the report to a responsible person of the minor.

A computer-readable storage medium having computer-executable instructions for performing a method to detect an electronic communication sent or received by a minor and relating to a sexual predatory behavior directed to the minor, said method comprising:

• specifying a the type of the sexual predatory behavior directed to the minor to detect whether the electronic communication relates to said type of the sexual predatory behavior directed to the minor wherein said type of the sexual predatory behavior includes one or more of the following:
• bullying behavior, offensive language, personal information solicitation or revelation, personal characteristics solicitation or revelation, meeting arrangement with a stranger, picture sharing with a stranger, or a combination thereof;
• parsing the electronic communication to generate a plurality of constituent tokens of the electronic communication;
• generating, in response to said tokens, a feature vector associated with the electronic communication, said feature vector indicating whether each one of a predefined set of one or more features relating to the type of the sexual predatory behavior directed to the minor is present in the electronic communication;
• and
• applying the generated feature vector to a probabilistic classifier relating to the type of the sexual predatory behavior to generate a rating for the electronic communication, wherein the probabilistic classifier trained on a content, anti-content, and close anti-content of the type of the sexual predatory behavior directed to the minor to identify said predefined set of one or more features, said rating indicating a probability that the electronic communication relates to the type of the sexual predatory behavior directed to the minor;
• categorizing the electronic communication as relating to the type of the sexual predatory behavior directed to the minor as a function of the rating;
• generating an alert to a responsible person of the minor if an electronic communication session associated with the electronic communication is still in progress, said alert indicative that the sexual predatory behavior directed to the minor is in progress;
• generating a report if the electronic communication is categorized as relating to the sexual predatory behavior directed to the minor, said report indicative that the sexual predatory behavior directed to the minor has occurred;
• and
• sending the report to the responsible person of the minor.
