QUERY EXPANSION USING ADD-ON TERMS WITH ASSIGNED CLASSIFICATIONS

摘要

In various embodiments, systems and methods are provided for query expansion using add-on terms with classifications. A query is received. An add-on term is identified for the query. A classification is determined for the add-on term. The classification is a designation associated with the add-on term that is used to distinguish the add-on term from the query. An appended query is generated based on the add-on term. The appended query is generated by concatenating the query with the add-on term. The appended query is executed on a resource stack as a single reformulated query to identify one or more resources. Upon execution, the classification of the add-on term distinguishes the one or more resources identified for the add-on term based on tagging the one or more resources with the classification of the add-on term. The appended query is used to generate content items.

1. One or more computer-readable media storing computer-useable instructions that, when used by one or more computing devices, cause the one or more computing devices to perform a method for query expansion based on add-on terms with assigned classifications, the method comprising:
receiving a query; identifying an add-on term for the query; determining a classification for the add-on term; generating an appended query by concatenating the query with the add-on term, wherein the appended query is executed on a resource stack as a single reformulated query to identify one or more resources such that the classification of the add-on term distinguishes the one or more resources identified for the add-on term based on tagging the one or more resources with the classification of the add-on term when the appended query is executed; utilizing the appended query to generate content items based on the one or more resources, wherein the one or more resources are tagged with the classification of the add-on term.
