Computer Method and System for Detecting the Subject Matter of Online Communications

A computer-implemented system and method for monitoring the electronic communications of a subject to determine if dangerous behavior is occurring, especially in social networking platforms. The PG Guard(TM) web service permits a parent to monitor all of a child's activities on a social site such as Facebook®. To maintain the privacy of the child, the service only provides information to the parents about suspicious activities comprising, for example: conversations regarding violence, sex, alcohol, etc.; when a stranger interacts with their child (or vice versa); when their child discloses personal information; when a friend seems to be of a problematic nature; when a child uploads or is tagged in new images; and when a child adds or rejects a new friend. The method comprises generating a profile of the subject based on their keywords and the probability of their intended meaning, as well as their posted "Likes" and "Recommendations".
