The paper describes a computational system, an application and implementation of the mature Ontological Semantic Technology, for detecting unintentional inferences in casual unsolicited and unrestricted verbal output of individuals, potentially responsible for leaked classified information to people with unauthorized access. Uses of the system for cases of insider threat and/or social engineering are discussed.
