Abstract

A method, computer program and information processing apparatus for flagging anomalies in text data are proposed. For example, a method of flagging suspicious electronic messages comprises detecting an anomalous segment in natural language content of an electronic message purporting to be sent or written by a particular individual, the detection using anomaly detection rules derived from natural language message content of a set of electronic messages previously sent by the particular individual. For a detected anomalous segment, a segment of text in an electronic message of the set which is closest to text in the anomalous segment, and an associated rule of the anomaly detection rules which is satisfied by the closest segment, are identified. A human-interpretable anomaly explanation based on the anomalous segment and the associated rule is generated.
