UNIFIED RANKING ENGINE FOR A SEARCH SYSTEM

Abstract:

Methods, systems, and computer storage media for providing unified ranking of search result items based on a user-configured ranking attribute for an item listing in an item listing platform. In particular, a unified ranking engine determines a user-configured ranking attribute for an item listing, which is used as part of a boosting model of the unified ranking engine to rank item listings. In operation, an item listing is assigned a boost factor based on the item listing having the user-configured ranking attribute. The boost factor indicates a value that is used to rank the item listing relative to the other item listings of search results item listing. The search result items include a first set of item listings that are promoted listings associated with the user-configured ranking attribute (e.g., promoted-listing ad rates) and second set of listings that are organic listings without user-configured ranking attributes.
