Statistical identification of instances during reconciliation process

摘要

A system for reconciling object for a configuration management databases employs statistical rules to reduce the amount of manual identification required by conventional reconciliation techniques. As users manually identify matches between source and target datasets, statistical rules are developed based on the criteria used for matching. Those statistical rules are then used for future matching. A threshold value is adjusted as the statistical rules are used, incrementing the threshold value when the rule successfully matches source and target objects. If the threshold value exceeds a predetermined acceptance value, the system may automatically accept a match made by a statistical rule. Otherwise, suggestions of possibly applicable rules may be presented to a user, who may use the suggested rules to match objects, causing adjustment of the threshold value associated with the suggested rules used.

1. A method comprising:
selecting a first configuration item from a source dataset; determining whether the first configuration item matches a second configuration item of a target dataset of a configuration management database based on application of a statistical rule; and responsive to a successful match based on the application of the statistical rule:
determining whether a threshold value associated with the statistical rule meets a predetermined acceptance value associated with the statistical rule, the threshold value and the predetermined acceptance value being independent of the first configuration item and the second configuration item,responsive to determining that the threshold value meets the predetermined acceptance value, marking the first configuration item as identified with the second configuration item, andadjusting the threshold value.
