Information processing apparatus, information processing method and computer readable medium

1. An information processing apparatus comprising:

processing circuitry

to extract a difference between each of three or more pieces of operation setting data which are pieces of data each of which is for setting operation in a device by comparing each of the three or more pieces of operation setting data, compute a matching rate between each of the three or more pieces of operation setting data, decide based on computed matching rates, an extraction order when extracting a difference between each of three or more pieces of associated operation setting data that are associated with the three or more pieces of operation setting data in a one-to-one manner, extract the difference between each of the three or more pieces of associated operation setting data according to the decided extraction order, and generate difference information indicating the extracted difference between each of the three or more pieces of associated operation setting data, before a user requests;

to store in an arbitrary storage device, the difference information generated; and

to acquire the difference information from the storage device and output the acquired difference information to an arbitrary display device when the user requests.

2. The information processing apparatus according to claim 1 ,

wherein the processing circuitry decides the extraction order according to one of a descending order of the matching rates and an ascending order of the matching rates.

3. The information processing apparatus according to claim 1 ,

wherein the processing circuitry decides not to extract a difference between two pieces of associated operation setting data associated with two pieces of data matching rate between which is smaller than a threshold among the three or more pieces of operation setting data.

4. An information processing method comprising:

extracting a difference between each of three or more pieces of operation setting data which are pieces of data each of which is for setting operation in a device, by comparing each of the three or more pieces of operating setting data, computing a matching rate between each of the three or more pieces of operation setting data, deciding based on computed matching rates, an extraction order when extracting a difference between each of three or more pieces of associated operation setting data that are associated with the three or more pieces of operation setting data in a one-to-one manner, extracting the difference between each of the three or more pieces of associated operation setting data according to the decided extraction order, and generating difference information indicating the extracted difference between each of the three or more pieces of associated operation setting data, before a user requests;

storing in an arbitrary storage device, the generated difference information; and

acquiring the difference information from the storage device and outputting the acquired difference information to an arbitrary display device when the user requests.

5. A non-transitory computer readable medium storing an information processing program which causes a computer to execute:

a difference extraction process of extracting a difference between each of three or more pieces of operation setting data which are pieces of data each of which is for setting operation in a device, by comparing each of the three or more pieces of operating setting data, computing a matching rate between each of the three or more pieces of operation setting data, deciding based on computed matching rates, an extraction order when extracting a difference between each of three or more pieces of associated operation setting data that are associated with the three or more pieces of operation setting data in a one-to-one manner, extracting the difference between each of the three or more pieces of associated operation setting data according to the decided extraction order, and generating difference information indicating the extracted difference between each of the three or more pieces of associated operation setting data, before a user requests;

a difference information storing process of storing in an arbitrary storage device, the difference information generated by the difference extraction process; and

a request response process of acquiring the difference information from the storage device and outputting the acquired difference information to an arbitrary display device when the user requests.
