Abstract
In various example embodiments, a system and method for determining query aspects for appropriate categories is provided. In example embodiments, query data is collected. The query data indicates a query term and tracked user behavior associated with past queries involving the query term. An aspect demand ratio is calculated for each category of a category tree based on the collected query data. Using at least one processor, one or more lowest categories of the category tree that satisfies a category threshold is determined. The one or more lowest categories are then appended to the query term and stored in a database.
