Application ID: 11642828

Base Claim:
1. A program stored on a computer-readable medium, which refers to a first data schema and a second data schema that describe data structures to correlate a data item name constituting the first data schema with a data item name constituting the second data schema, the program being implemented on and controlling a computer to execute the procedures of: extracting the data item name constituting the first data schema; extracting the data item name constituting the second data schema; extracting element concepts included in the extracted data item names of the first data schema and the second data schema; setting a distinctive relation and a time-sequential order relation between the data item names based on the extracted element concepts; reading the data item names of the first data schema and the second data schema and setting a correlation between the two read data item names based on the distinctive relation to satisfy a constraint imposed by the time-sequential order relation between the data item names; and accumulating the correlation of the data item names; reading two data item names of one of the first data schema and the second data schema; extracting a set of common character strings from among character strings constituting the two data item names as a first element concept when character strings of the two data item names are compared with each other and are judged to include synonymous character strings; and extracting a set of character strings excluding common character strings from the character strings constituting the two data item names as a second element concept when the character strings of the two data item names are compared with each other and are judged to include synonymous character strings; judging a time-sequential order relation for the two item names corresponding to the second element concept; and setting that the set of character strings constituting the second element concept has a distinctive relation when no time-sequential order relation is included in the second element concept.

Claim 2:
2. The program according to claim 1 , wherein the correlation procedure sets that the two data items correspond to each other when the character strings of the two read data item names are compared with each other and are judged to include the synonymous character stings but not to have a distinctive relation.
