Dictionary creation apparatus, dictionary creation method, and non-transitory computer-readable storage medium for storing dictionary creation program

A dictionary creation method implemented by a computer, the method comprising:

• extracting a first plurality of character strings from a first dictionary to determine types of the first plurality of extracted character strings, the first plurality of character strings having a common part at a part thereof, a first dictionary including character strings extracted from a log of a first apparatus;
• extracting a second plurality of character strings having the common part from the log of the first apparatus to determine types of the second plurality of character strings;
• executing a first determination processing that includes determining whether the types of the first plurality of character strings are limited with respect to the types of the second plurality of character strings;
• executing a second determination processing in response to a determination result indicating that the types of the first plurality of character strings are limited with respect to the types of the second plurality of character strings, the second determination processing including
• extracting a third plurality of character strings having the common part at a part thereof from a log of a second apparatus different from the first apparatus,
• determining types of the third plurality of character strings, and
• determining whether a matching degree between the types of the third plurality of character strings and the types of the second plurality of character strings is equal to or greater than a predetermined value;
• and
• executing a dictionary editing processing in response to a determination result indicating that the matching degree is equal to or greater than the predetermined value, the dictionary editing processing including registering the first plurality of character strings into a second dictionary configured to store character strings extracted from the log of the second apparatus are registered.

A non-transitory computer-readable storage medium for storing a dictionary creation program which causes a processor to perform processing, the processing comprising:

• extracting a first plurality of character strings from a first dictionary to determine types of the first plurality of extracted character strings, the first plurality of character strings having a common part at a part thereof, a first dictionary including character strings extracted from a log of a first apparatus;
• extracting a second plurality of character strings having the common part from the log of the first apparatus to determine types of the second plurality of character strings;
• executing a first determination processing that includes determining whether the types of the first plurality of character strings are limited with respect to the types of the second plurality of character strings;
• executing a second determination processing in response to a determination result indicating that the types of the first plurality of character strings are limited with respect to the types of the second plurality of character strings, the second determination processing including
• extracting a third plurality of character strings having the common part at a part thereof from a log of a second apparatus different from the first apparatus,
• determining types of the third plurality of character strings, and
• determining whether a matching degree between the types of the third plurality of character strings and the types of the second plurality of character strings is equal to or greater than a predetermined value;
• and
• executing a dictionary editing processing in response to a determination result indicating that the matching degree is equal to or greater than the predetermined value, the dictionary editing processing including registering the first plurality of character strings into a second dictionary configured to store character strings extracted from the log of the second apparatus are registered.
