Methods and systems to analyze aspect rules based on domain coverage of the aspect rules are provided. The system receives a first plurality of data items from a database, applies a first plurality of rules to the first plurality of data items to generate a second plurality of data items associated with a first domain, counts the second plurality of data items to determine a total quantity of data items, applies a second plurality of rules to the second plurality of data items to identify a third plurality of data items associated with a first aspect counts the third plurality of data items to determine a first quantity of data items, determines a percentage of coverage for the first aspect based on the first quantity of data items and the total quantity of data items, and provides the percentage of coverage as an interface element within an interface.
