Related document search system, device, method and program

A related document search device comprising:

• procedure group creation means for extracting data of a portion corresponding to a procedure indicating operation or state from document data and creating a group of the procedures to which all the procedures that are required to be performed in order to solve a problem belong by using the data of the portion corresponding to the extracted procedures as information on a procedure group and
• supplementary information detection means for detecting the procedure group including the procedure that is the same as or similar to any procedure which belongs to the procedure group included in a predetermined document data and the procedure that is not the same as or not similar to any procedure which belongs to the procedure group included in the predetermined document data from related document data by using information on the procedure group created by the procedure group creation means as the procedure group including supplementary information which supplements the content of the predetermined document data.

A program recording medium for storing a related document search program which causes a computer to perform:

• a procedure group creation process in which data of a portion corresponding to a procedure indicating operation or state is extracted from document data and a group of procedures to which all procedures that are required to be performed in order to solve a problem belong is created by using the data of the portion corresponding to the extracted procedure as information on a procedure group and
• a supplementary information detection process in which the procedure group including a procedure that is the same as or similar to any procedure which belongs to the procedure group included in a predetermined document data and a procedure that is not the same as or not similar to any procedure which belongs to the procedure group included in the predetermined document data is detected from related document data by using the created information on the procedure group as the procedure group including supplementary information which supplements the content of the predetermined document data.
