Fault processing method and system
Various embodiments of the teachings herein include a fault processing method comprising: receiving two historical faults similar to a target fault; searching keywords in a description of the target fault and each historical fault, wherein the keywords are classified into N grades, and for each system component in a grade, the grade comprises at least one keyword for describing the component, wherein N is an integer no less than 2; for each of the N grades, counting a quantity of identical system components represented by the keywords in the text description of each historical fault and the target fault; and comparing a degree of similarity of each historical fault to the target fault according to the quantity of identical system components counted in each grade of the N different grades, wherein a historical fault relating to a larger number of high-grade identical system components has a higher degree of similarity to the target fault.
1. A fault processing method comprising:
receiving two historical faults similar to a target fault;
searching predefined keywords in a description of the target fault and a respective text description of each historical fault, wherein the predefined keywords are classified into N different grades, and for each system component in a grade, the grade comprises at least one keyword for describing the system component, wherein N is an integer no less than 2;
for each of the N different grades, counting a quantity of identical system components represented by the keywords in the grade in the text description of each historical fault and the keywords in the grade in the text description of the target fault, respectively; and
comparing a degree of similarity of each historical fault to the target fault according to the quantity of identical system components counted in each grade of the N different grades, wherein a historical fault relating to a larger number of high-grade identical system components has a higher degree of similarity to the target fault.
2. The method as claimed in claim 1 , further comprising obtaining the two historical faults from a fault case retrieval system.
3. The method as claimed in claim 1 , wherein the method further comprises removing historical faults from the two historical faults if the number of identical system components related to the historical faults is 0 for each of the N different grades.
4. The method as claimed in claim 1 , further comprising determining N based on a quantity of layers of the system composition of the target system related to the target fault, and the larger the number of layers of the system composition of the target system is, the larger N is.
5. A fault processing system comprising:
one or more processors in communication with a memory;
the memory storing a set of instructions;
the set of instructions causing one or more of the processors to function as:
a receiving module configured to receive two historical faults similar to a target fault;
a searching module configured to search predefined keywords in a text description of the target fault and a respective text description of each historical fault, wherein the predefined keywords are classified into N different grades, and for each system component in a grade, the grade comprises a keyword for describing the system component, wherein N is an integer no less than 2;
a counting module configured to count a quantity of identical system components represented by the keywords in the grade in the text description of each historical fault and the keywords in the grade in the text description of the target fault respectively for each of N different grades; and
a processing module configured to compare a degree of similarity of each historical fault to the target fault according to a number of identical system components counted in each grade of the N different grades, wherein a historical fault relating to a larger number of high-grade identical system components has a higher degree of similarity to the target fault.
6. The fault processing system as claimed in claim 5 , further comprising a fault case retrieval system obtaining the two historical faults.
