A disclosed method includes: generating a first rule for each parameter from first data including a parameter value of each parameter; generating a second rule for each parameter from second data that is data after at least one parameter value included in the first data was changed; generating, for each group including one or plural parameters, a pair of the first rule and the second rule, which include a parameter of the group; calculating, for each pair, a first consistency ratio by applying the first rule included in the pair to the second data and a second consistency ratio by applying the second rile included in the pair to the first data; with respect to a first pair whose second consistency ratio exceeds the first consistency ratio, presenting a parameter value of a parameter, which contradicts the second rule included in the pair, in the second data to a user.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A computer-readable, non-transitory storage medium storing a program for causing a computer to execute a process comprising: first generating a first rule for each of a plurality of parameters from first data including a parameter value of each of the plurality of parameters for each of a plurality of setting targets; second generating a second rule for each of the plurality of parameters from second data that is data after at least one parameter value included in the first data was changed; third generating, for each group including one or plural parameters among the plurality of parameters, a pair of the first rule and the second rule, which include a parameter of the group; calculating, for each pair of a plurality of generated pairs, a first consistency ratio by applying the first rule included in the pair to the second data and a second consistency ratio by applying the second rule included in the pair to the first data; with respect to a first pair whose second consistency ratio exceeds the first consistency ratio, first presenting a parameter value of a parameter, which contradicts the second rule included in the pair, in the second data to a user; and with respect to a second pair whose first consistency ratio exceeds the second consistency ratio, second presenting a changed parameter value among parameter values of parameters relating to the pair to the user. 2. The computer-readable, non-transitory storage medium as set forth in claim 1, wherein, in the first presenting or the second presenting, the changed parameter value is displayed so as to be distinguished according to a difference or a ratio between the first consistency ratio and the second consistency ratio. 3. The computer-readable, non-transitory storage medium as set forth in claim 1, wherein the process further comprises: upon detecting that the first consistency ratio is equal to the second consistency ratio, presenting the changed parameter value to the user. 4. The computer-readable, non-transitory storage medium as set forth in claim 1, wherein the third generating comprises excluding, in the group, a pair whose first rule is identical with the second rule and a pair that one of the first rule and the second rule includes the other. 5. The computer-readable, non-transitory storage medium as set forth in claim 1, wherein the first consistency ratio is calculated by counting a first number of setting targets including a parameter value that satisfies a condition of the first rule, counting a second number of times that a parameter value of a parameter that is included in the setting targets counted for the first number and is a target of the first rule is identical to a parameter value in a conclusion part included in the first rule, and dividing the second number of times by the first number of setting targets, and the second consistency ratio is calculated by counting a third number of setting targets including a parameter value that satisfies a condition of the second rule, counting a fourth number of times that a parameter value of a parameter that is included in the setting targets counted for the third number and is a target of the second rule is identical to a parameter value in a conclusion part included in the second rule, and dividing the fourth number of times by the third number of setting targets. 6. An information processing method, comprising: first generating, by using a computer, a first rule for each of a plurality of parameters from first data including a parameter value of each of the plurality of parameters for each of a plurality of setting targets; second generating, by using the computer, a second rule for each of the plurality of parameters from second data that is data after at least one parameter value included in the first data was changed; third generating, by using the computer and for each group including one or plural parameters among the plurality of parameters, a pair of the first rule and the second rule, which include a parameter of the group; calculating, by using the computer for each pair of a plurality of generated pairs, a first consistency ratio by applying the first rule included in the pair to the second data and a second consistency ratio by applying the second rule included in the pair to the first data; with respect to a first pair whose second consistency ratio exceeds the first consistency ratio, first presenting, by using the computer, a parameter value of a parameter, which contradicts the second rule included in the pair, in the second data to a user; and with respect to a second pair whose first consistency ratio exceeds the second consistency ratio, second presenting, by using the computer, a changed parameter value among parameter values of parameters relating to the pair to the user. 7. An information processing apparatus, comprising: a memory; and a processor configured to use the memory and execute a process comprising: first generating a first rule for each of a plurality of parameters from first data including a parameter value of each of the plurality of parameters for each of a plurality of setting targets ; second generating a second rule for each of the plurality of parameters from second data that is data after at least one parameter value included in the first data was changed; third generating, for each group including one or plural parameters among the plurality of parameters, a pair of the first rule and the second rule, which include a parameter of the group; calculating, for each pair of a plurality of generated pairs, a first consistency ratio by applying the first rule included in the pair to the second data and a second consistency ratio by applying the second rule included in the pair to the first data; with respect to a first pair whose second consistency ratio exceeds the first consistency ratio, first presenting a parameter value of a parameter, which contradicts the second rule included in the pair, in the second data to a user; and with respect to a second pair whose first consistency ratio exceeds the second consistency ratio, second presenting a changed parameter value among parameter values of parameters relating to the pair to the user.
