Device and method for automatically detecting an unclear description

A computer-readable, non-transitory medium storing a program used to direct a computer to perform the processes, the processes comprising:

• calculating, based on a common command commonly included in a plurality of process logs including a history of executed commands, a matching level of a process preceding the common command in the plurality of process logs, or a matching level of a process subsequent to the common command in the plurality of process logs;
• when the calculated matching level is equal to the matching level of the preceding process, outputting the matching level as associated with instruction manual data before the common command in instruction manual data including the common command;
• and
• when the calculated matching level is equal to the matching level of the subsequent process, outputting the matching level or a comparison result between the matching level and a specified threshold as associated with instruction manual data after the common command in instruction manual data including the common command.

A device which automatically detects an unclear description by extracting an unclear part in an instruction manual describing a processing instruction when managing and operating an information processing system, the device comprising:

• a log acquisition unit to acquire a log of processes performed by a plurality of instruction executers according to the instruction manual;
• an intra-instruction-manual command extraction unit to extract a command and its line position in the instruction manual;
• an intra-log command extraction unit to extract the command extracted by the intra-instruction-manual command extraction unit from each of the plurality of logs, and divide the command into inter-command sections;
• an unclear level evaluation unit used in the inter-command sections in the log, to count a number of executions of a command different from the extracted command with respect to the plurality of logs, and calculate a variance of the number of executions for each command among the plurality of logs;
• and
• an unclear part presentation unit to display a section of an instruction manual including a command whose variance is larger than a specified value according to a calculation result of the unclear level evaluation unit as a part which is possibly an unclear description.

A method used by a computer for detecting an unclear description by extracting an unclear part in an instruction manual describing a processing instruction when managing and operating an information processing system, the method comprising:

• acquiring a log of processes performed by a plurality of instruction executers according to the instruction manual;
• extracting a command and its line position in the instruction manual;
• extracting the command extracted by intra-instruction-manual command extraction from each of the plurality of logs, and dividing the command into inter-command sections;
• being used in the inter-command sections in the log for counting a number of executions of a command different from the extracted command with respect to the plurality of logs, and calculating a variance of the number of executions for each command among the plurality of logs;
• and
• displaying a section of an instruction manual including a command whose variance is larger than a specified value according to a calculation result as a part which is possibly an unclear description.
