15. A system, comprising: a processor; and a memory device including instructions that, when executed by the processor, cause the system to: provide a first item categorization for a set of items; determine at least one attribute associated with the first item categorization; identify at least one first item of the set of items for which the associated at least one attribute is empty based at least in part on identifying a plurality of attributes inherited from a parent item category associated with the at least one first item and at least one second item, the parent item category being a parent node to a child node associated with the at least one first item and the at least one second item in a browse-node hierarchy; determine, from one or more second items of the set of items, a range of existing values for the attribute; associate a set of priority indicators with the range of existing values, the set of priority indicators generated based at least in part on pre-determined rules that utilize a context associated with an existing value of the range of existing values to represent importance of the existing value in comparison to other existing values, the context based at least in part on a set of existing values of the plurality of existing values identified by the pre-determined rules that are associated with a position of a given existing value within text of the at least one first item; implement a rule engine that implements a rule set specified by a user to iteratively alter the rule set after removing one or more values from the range of existing values to prioritize remaining values of the range of existing values based at least in part on the set of priority indicators; filter the prioritized remaining values from the rule engine to determine at least one potential value for the attribute based at least in part on the range of existing values and the prioritized remaining values; determine, from the at least one potential value for the attribute, a probable value; and set the at least one attribute associated with the first item to the probable value.

The system of claim 15 , wherein the at least one first item belongs to a second item categorization.
