Apparatus and method for extracting and sharing information

摘要

A message exchange unit receives and distributes a message in a community in which a plurality of users participates. A message memory stores the message received by the message exchange unit. An extraction rule memory stores an extraction rule applicable for the message. The extraction rule includes an extraction pattern, an extraction target and a display format. An information extraction unit extracts information from the message stored in the message memory by referring to the extraction rule. An extraction result memory stores extraction result information by the information extraction unit. An extraction result editing unit edits the extraction result information stored in the extraction result memory. A message generation unit generates another message representing editing of the extraction result information.
