In one embodiment, a computing device may collect a plurality of information items of a plurality of types relevant to a user; rank the plurality of information items based on their respective degrees of relevance to the user; construct an information feed that includes the plurality of information items in an order of their respective ranks; and send the information feed to a user device associated with the user for presentation of the plurality of information items to the user in the order of their respective ranks.
1. A method comprising:
collecting, by one or more computing devices, a plurality of information items of a plurality of types relevant to a user, wherein:
the information items are collected from at least one social-networking system and at least one third-party system; and
the user is a member of the at least one social-networking system;
determining, by one or more computing devices, a relevance value for each of the information items, wherein the relevance value is based at least in part on:
how close a time associated with the information item is to a current time; and
how close a node representing the information item is to a node representing the user in a graph associated with the social-networking system, the graph representing information contained in the social-networking system;
classifying, by one or more computing devices, one or more of the information items as being non-deterministic based at least in part on each of the non-deterministic information items having a relevance value that decreases with time;
classifying, by one or more computing devices, one or more other ones of the information items as being deterministic based at least in part on each of the deterministic information items having a relevance value that remains substantially constant over time;
sending, by one or more computing devices, one or more push notifications to one or more client devices associated with the user, the push notifications comprising one or more of the non-deterministic information items sent in an order of their respective relevance values; and
storing, by one or more computing devices, the deterministic information items for later retrieval by the user.
2. The method of claim 1 , wherein the one or more push notifications are sent as one or more Short Message Service (SMS) notifications or as an information feed.
3. The method of claim 1 , further comprising boosting one or more relevance values of one or more of the information items.
4. The method of claim 3 , wherein the information items whose relevance values are boosted are non-deterministic.
5. The method of claim 3 , wherein the information items whose relevance values are boosted are each associated with a time that is close to the current time.
6. The method of claim 3 , wherein the information items whose relevance values are boosted are each associated with a location that is near to a current location of the user.
7. A system comprising:
one or more processors; and
a memory coupled to the processors comprising instructions executable by the processors, the processors being operable when executing the instructions to:
collect a plurality of information items of a plurality of types relevant to a user, wherein:
the information items are collected from at least one social-networking system and at least one third-party system; and
the user is a member of the at least one social-networking system;
determine a relevance value for each of the information items, wherein the relevance value is based at least in part on:
how close a time associated with the information item is to a current time; and
how close a node representing the information item is to a node representing the user in a graph associated with the social-networking system, the graph representing information contained in the social-networking system;
classify one or more of the information items as being non-deterministic based at least in part on each of the non-deterministic information items having a relevance value that decreases with time;
classify one or more other ones of the information items as being deterministic based at least in part on each of the deterministic information items having a relevance value that remains substantially constant over time;
send one or more push notifications to one or more client devices associated with the user, the push notifications comprising one or more of the non-deterministic information items sent in an order of their respective relevance values; and
store the deterministic information items for later retrieval by the user.
8. The system of claim 7 , wherein the one or more push notifications are sent as one or more Short Message Service (SMS) notifications or as an information feed.
9. The system of claim 7 , wherein the one or more processors are further operable when executing the instructions to boost one or more relevance values of one or more of the information items.
10. The system of claim 9 , wherein the information items whose relevance values are boosted are non-deterministic.
11. The system of claim 9 , wherein the information items whose relevance values are boosted are each associated with a time that is close to the current time.
12. The system of claim 9 , wherein the information items whose relevance values are boosted are each associated with a location that is near to a current location of the user.
13. One or more computer-readable non-transitory storage media embodying software that is operable when executed to:
collect a plurality of information items of a plurality of types relevant to a user, wherein:
the information items are collected from at least one social-networking system and at least one third-party system; and
the user is a member of the at least one social-networking system;
determine a relevance value for each of the information items, wherein the relevance value is based at least in part on:
how close a time associated with the information item is to a current time; and
how close a node representing the information item is to a node representing the user in a graph associated with the social-networking system, the graph representing information contained in the social-networking system;
classify one or more of the information items as being non-deterministic based at least in part on each of the non-deterministic information items having a relevance value that decreases with time;
classify one or more other ones of the information items as being deterministic based at least in part on each of the deterministic information items having a relevance value that remains substantially constant over time;
send one or more push notifications to one or more client devices associated with the user, the push notifications comprising one or more of the non-deterministic information items sent in an order of their respective relevance values; and
store the deterministic information items for later retrieval by the user.
14. The media of claim 13 , wherein the one or more push notifications are sent as one or more Short Message Service (SMS) notifications or as an information feed.
15. The media of claim 13 , wherein the software is further operable when executed to boost one or more relevance values of one or more of the information items.
16. The media of claim 15 , wherein the information items whose relevance values are boosted are non-deterministic.
17. The media of claim 15 , wherein the information items whose relevance values are boosted are each associated with a time that is close to the cunent time.
18. The media of claim 15 , wherein the information items whose relevance values are boosted are each associated with a location that is near to a cunent location of the user.
