A dimensional translator may automatically translate a dimension from an entity to a different dimension of another entity. The dimensional translator may do so by comparing attributes of the input dimension (the dimension to be translated) to attributes of a target data structure. An attribute may include, for example, hierarchy of a data structure, relationships of a data structure, a keyword associated with a data structure, and a data value associated with the data structure. The dimensional translator may automatically determine how a target entity would categorize the item. In particular, a Universal Product Code dimension of an item provided by an entity may be translated into a data structure of a target entity such as a retailer in order to determine how an item identified by the UPC will be categorized by the retailer.
