Abstract
A computer-implemented approach for processing search queries generally involves normalizing names and descriptions of items. The various forms of a name or description of an item is referred to as an item name variant. The normalized form of the name or description of an item is referred to as a normalized item name. Item name variants that are similar are grouped together to form clusters. Each cluster of item name variants is mapped to a normalized item name. A dictionary of normalized item names are created by storing: 1) the item name variant, 2) the information that is obtained from the item name source and which is associated with the item name variant, and 3) the mapping information that maps the item name variant to the corresponding normalized item name.
