Social-driven precaching of accessible objects

摘要

A precaching system identifies an object, such as a media file, that a user accesses and then analyzes a social graph of the user to identify social graph contacts that may be interested in the object. Based on the content of the object—and the interests and connections of contacts in the social graph—the precaching system determines whether a particular contact in the user's social graph is likely also to access the object. For example, the precaching system may determine a hit score corresponding to the object and a likelihood that the particular contact in the social graph will access the object. If the precaching system determines that the likelihood that the particular contact will access the object meets or exceeds a threshold probability level for precaching the object, the precaching system precaches the object near the contact in anticipation that the contact will access the object.

主权项

1. A method to precache objects, comprising:
identifying, by one or more computing devices, a particular object previously accessed by a user computing device of a user; determining, by the one or more computing devices and for a computing device of a social graph contact of the user, a probability that the computing device of the social graph contact will access the particular object, the probability determined based at least in part on a strength of connection between the social graph contact and the user within the social graph; determining, by the one or more computing devices, that the probability that the computing device of the social graph contact will access the particular object meets or exceeds a threshold probability for precaching accessible objects; in response to determining that the probability that the computing device of the social graph contact will access the particular object meets or exceeds the threshold probability:
determining, by the one or more computing devices, one or more access point locations near the computing device of the social graph contact;identifying, by the one or more computing devices, a precaching location to cache the particular object based on the determined one or more access point locations near the computing device of the social graph contact; andprecaching, by the one or more computing devices, the particular object at the identified precaching location.
