Mining Search Logs for Query Metadata on Online Social Networks

摘要

In one embodiment, a method includes receiving, from a client system associated with a first user of an online social network, a search query; parsing the search query to identify one or more n-grams; retrieving, for each identified n-gram, metadata from a mining-search-log database, where the metadata includes at least top N entity identifiers corresponding to entities associated with the identified n-gram and their respective click-through rates, and top K co-occurring n-grams for the identified n-gram; identifying a plurality of content objects matching the search query; ranking the content objects based on whether the content objects contain one or more of the top N entity identifiers or one or more of the top K co-occurring n-grams; and sending, to the client system, instructions for presenting one or more search results corresponding to the identified content objects in an order based on the ranking of the corresponding content objects.
