Computer-Implemented System And Method For Identifying Duplicate And Near Duplicate Messages

A computer-implemented system and method for identifying duplicate and near duplicate messages is provided. A set of messages is obtained. A body of one such message is compared with the body of each other message. Those messages having matching bodies are identified as exact duplicates. The exact duplicates are removed from the set. The remaining messages are sorted in order of message length and a shorter message is compared with a longer message. A determination is made that the body of the shorter message is included in the body of the longer message and the shorter message is marked as a near duplicate of the longer message.
