1. A computer-implemented method comprising: receiving content information indicating content electronically viewed by a user on a computing device; identifying, based on the content information, one or more entities referred to in the content, wherein identifying at least one entity of the one or more entities is further based on proximity of the at least one entity to a location associated with the computing device, and wherein each of the one or more entities is associated with a weight value indicating a likelihood that the corresponding entity is a referent of the content; identifying, for the at least one entity referred to in the content, one or more actions that are mapped to the at least one entity in an entity database; receiving, via the computing device of the user and subsequent to receiving the content information, a request to enter a query into a search field; and providing, for display with the search field in response to the request to enter the query into the search field, an identifier of the at least one entity and an identifier of a first action of the one or more actions that are mapped to the at least one entity; wherein selection of the identifier of the first action via the computing device causes additional content to be displayed at the computing device that is specific to the first action for the at least one entity.
