Abstract: Type completeness detection methods and systems are provided to determine a browse node completeness score for browse nodes in an electronic catalog. For example, the type completeness detection system may select a browse node, identify a plurality of search queries previously submitted by users of the electronic catalog, determine a plurality of items that are frequently selected after submitting the search queries, calculate a query completeness score for each search query, determine a browse node completeness score for the browse node, and initiate an action in response to determining that the browse node completeness score falls below a threshold value.

Abstract: Type ambiguity detection methods and systems are provided to predict a browse node classification for items in an electronic catalog and determine ambiguity between browse nodes based at least partly on the predicted browse node classifications for the items. For example, the type ambiguity detection system may identify a plurality of search queries previously submitted by users of the electronic catalog, determine a plurality of browse nodes that are frequently selected after submitting the search queries, determine items that consumers frequently view or purchase in connection with the search queries, input the items into a classifier, receive an output predicting a proper item type or browse node for a given item, and initiate an action in response to determining ambiguity.
