Conditioned Search Ranking Models on Online Social Networks

摘要

In one embodiment, a method includes a computing system receiving a query from a first user, which can be parsed to identify i conditions associated with the query. The system may then identify one or more search results substantially matching the i conditions. Each search result may be associated with a feature vector of j features. The system may then access a conditioned ranking model that comprises j scoring functions for each i condition. The j scoring functions may correspond to j features of the feature vectors. A score for each search result may be calculated based on the i conditions and the j features. The system may then receive a selection of one of the search results from the first user, and in response modify one or more of the j scoring functions of the conditioned ranking model based on the selection.

1. A method comprising, by one or more computing devices:
receiving a query from a first user; parsing the received query to identify i conditions associated with the received query; identifying one or more search results substantially matching the i conditions associated with the received query, each search result being associated with a feature vector of j features; accessing a conditioned ranking model, wherein the conditioned ranking model comprises:
for each i condition, j scoring functions corresponding to j features of the feature vector associated with each search result; anda ranking algorithm for determining a rank of each search result; calculating a score for each search result based at least in part on the i conditions and the j features as associated with each i condition; receiving, from the first user, a selection of one of the search results; and modifying one or more of the j scoring functions of the conditioned ranking model based at least in part on the selected search result by the first user.
