Rule based de-duplication of software system defects

A non-transitory computer readable storage medium storing instructions that when executed by one or more computer processors cause the one or more computer processors to perform steps comprising:

• storing records describing system defects for a plurality of external systems, each system defect associated with an external system;
• configuring a user interface for display via a client device, the user interface displaying information stored in records describing system defects;
• receiving, one or more de-duplication rules, each de-duplication rule configured to receive a description of an input system defect and determine whether the input system defect is a duplicate of an original system defect associated with the de-duplication rule, the de-duplication rule specifying one or more regular expressions, wherein the input system defect is determined to be a duplicate responsive to satisfying the one or more regular expressions;
• executing a particular de-duplication rule configured to determine duplicate system defects for a particular system defect associated with a particular external system, the executing comprising whether a target system defect specified for the particular external system satisfies the one or more regular expressions specified by the de-duplication rule;
• determining based on the execution of the one or more regular expressions that the target system defect specified for the particular external system is a duplicate of the particular system defect;
• and
• storing in a record describing the target system defect, information indicating that the target system defect is a duplicate.
