Abstract
A method and system are disclosed for browsing an electronic hierarchical product catalog. The catalog is organized as a tree data structure with each node corresponding to an item category, an item sub-category, or an attribute that describes characteristics of items in a category. Such attributes may be used as filters for searching for an item or item category. The catalog tree is a collection of linked independent sub-trees including category and attribute sub-trees. The sub-trees allow navigation of the catalog tree via links between various nodes. The sub-trees may be linked to multiple other sub-trees, providing easy navigation for users and simplifying the addition of new sub-categories and attributes to the catalog tree, for service providers. The use of linked sub-trees also allows attributes set by the user in a previous search to be used in a subsequent search for a similar item.
