Abstract:
1. A non-transitory computer-readable medium storing a program that causes a computer to perform a process, wherein the computer comprises a document data memory unit that memorizes a taxonomy schema in which each of a plurality of item elements are defined with a tagged structured language, an instance document which includes a context in which an input value is stored in each of the item elements defined in the taxonomy schema, a display link base which includes a hierarchical structure of the item elements of the instance document in display processing, and a calculation link base which includes a reference relationship and a hierarchical structure of the item elements of the instance document in arithmetic processing, the process comprising: calculating an input value of each of the item elements of the instance document based on the hierarchical structure of the calculation link base; comparing one of the calculated input values and the stored input value of the instance document corresponding to the item element of the input value calculated in the calculating; detecting a discrepancy between the calculated input value and the stored input value by the comparing; specifying a calculation tree structure of the calculation link base in which the item element of the calculated input value in which the discrepancy is detected by the detecting is set; specifying a display tree structure of the display link base in which the item element of the stored input value in which the discrepancy is detected is set; comparing the item elements set in both of the calculation tree structure and the display tree structure, and inferring, as an error of the discrepancy, an excess or deficiency of an item element which exists in either of the calculation tree structure or the display tree structure and has an input value which is consistent with an absolute value of the difference between the stored input value and the calculated input value.
