System and method for presenting message threads

摘要

A system and method for presenting message threads is provided. A main body and one or more excerpts are parsed from each of a plurality of messages into nodes structured to form a message tree through a procedural top-down recursive descent. The nodes in the message tree are related by determining line-group types for the main body and the excerpts of each message, which are enumerated into partitions for each of the line-group types. An output network of alternative paths through the messages is created based upon the partitions of the message tree. A document is formed from the output network to identify and remove redundant components in each message.
