<P>PROBLEM TO BE SOLVED: To provide a data structure extraction program and a data structure extraction device which use frequencies of common data and data other than the common data among a plurality of appearing data structures and determine similar ones from the data structures and output them. <P>SOLUTION: A data structure extraction device 1 comprises: pattern extraction means 100 for extracting a pattern appearing at a frequency equal to or more than a first threshold from DPC data 111; threshold setting means 104 for comparing similar data structures with each other and setting the number of common data as a second threshold, if having further data other than data common for mutual data structures; pattern re-extraction means 105 for re-extracting a second data structure extracted at a frequency equal to or more than a second threshold; output determination means 106 for determining that the other data structure should be outputted, if only one of data structures to be compared with each other has further data other than common data; and output means 107 for outputting the extracted data structure. <P>COPYRIGHT: (C)2013,JPO&INPIT |
