Generating Cards in Response to User Actions on Online Social Networks

1 . A method comprising, by one or more computing devices:

receiving, at one or more of the computing devices from a client system associated with a first user of the online social network, an indication of a check-in at a geographical location by the first user;

generating, by one or more of the computing devices, a plurality of reaction-cards based at least in part on the check-in, each reaction-card being associated with a structured query referencing the geographical location, each reaction-card comprising one or more search results matching the structured query associated with the reaction-card; and

sending, from one or more of the computing devices to the client system, in response to receiving the indication of the check-in, instructions for presenting one or more of the reaction-cards, wherein the reaction-cards are presented in ranked order based on a relevance of the structured query associated with the respective reaction-card to the geographic location.

2 . The method of claim 1 , further comprising:

accessing, by one or more of the computing devices, a social graph comprising a plurality of nodes and a plurality of edges connecting the nodes, each of the edges between two of the nodes representing a single degree of separation between them, the nodes comprising:

a first node corresponding to the first user; and

a plurality of second nodes that each correspond to a concept or a second user associated with the online social network.

3 . The method of claim 2 , wherein the geographical location corresponds to one of the second nodes.

4 . The method of claim 3 , wherein the relevance of the structured query associated with the reaction-card to the geographic location is based on a relevance of the reaction-card to the second node associated with the geographic location.

5 . The method of claim 2 , wherein each search result corresponds to one of the second nodes.

6 . The method of claim 1 , further comprising:

receiving, at one or more of the computing devices from the client system, an indication of a trigger action performed on the client system, wherein the trigger action is a user interaction with a content object, the content object being associated with the geographic location.

7 . The method of claim 6 , wherein the trigger action is associated with a particular entity associated with the online social network, and wherein the structured query associated with each reaction-card comprises a reference to the particular entity associated with the trigger action.

8 . The method of claim 6 , wherein the trigger action is associated with a post, a comment, a like, a share, a tag, particular structured data associated with the online social network, or any combination thereof.

9 . The method of claim 6 , wherein the user interaction with the content object is a click on an URL associated with the content object, a like of the content object, a comment on the content object, a share of the content object, a tag on the 4 content object, or any combination thereof.

10 . The method of claim 1 , further comprising:

calculating a reaction-card score for each reaction-card, wherein the reaction-card score is based at least in part on the relevance of the structured query associated with the reaction-card to the geographical location and further based on one or more user-engagement factors; and

determining the ranked order based on the reaction-card score associated with each reaction-card.

11 . The method of claim 10 , wherein the user-engagement factors comprise one or more of demographic information, current information, and social-graph information of the first user.

12 . The method of claim 11 , wherein the current information of the first user comprises one or more of a location history of the first user, personal preference of the first user, or a search history of the first user.

13 . The method of claim 10 , wherein the user-engagement factors comprise one or more of sensor information, current time, or one or more of capabilities of the client system.

14 . The method of claim 10 , wherein the user-engagement factors comprise a social-graph affinity of the first user with respect to one or more objects referenced by the structured query.

15 . The method of claim 1 , wherein each structured query corresponds to a query-domain.

16 . The method of claim 15 , wherein the query-domain is associated with places, people, groups, applications, events, or photos.

17 . The method of claim 1 , further comprising:

receiving an input from the client system associated with the first user, the input corresponding to an interaction with a particular reaction-card; and

modifying the structured queries on one or more other reaction-cards based on the input.

18 . The method of claim 17 , further comprising:

sending, to the client system, instructions for displaying a subsequent reaction-card to the first user in response to detecting the input from the first user corresponding to the interaction of a previously displayed reaction-card, the subsequent reaction-card having a same query-domain and a different structured query as the previously displayed reaction-card.

19 . One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

receive, from a client system associated with a first user of the online social network, an indication of a check-in at a geographical location by the first user;

generate a plurality of reaction-cards based at least in part on the check-in, each reaction-card being associated with a structured query referencing the geographical location, each reaction-card comprising one or more search results matching the structured query associated with the reaction-card; and

send, to the client system, in response to receiving the indication of the check-in, instructions for presenting one or more of the reaction-cards, wherein the reaction-cards are presented in ranked order based on a relevance of the structured query associated with the respective reaction-card to the geographic location.

20 . A system comprising: one or more processors; and a memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to:

receive, from a client system associated with a first user of the online social network, an indication of a check-in at a geographical location by the first user;

generate a plurality of reaction-cards based at least in part on the check-in, each reaction-card being associated with a structured query referencing the geographical location, each reaction-card comprising one or more search results matching the structured query associated with the reaction-card; and

send, to the client system, in response to receiving the indication of the check-in, instructions for presenting one or more of the reaction-cards, wherein the reaction-cards are presented in ranked order based on a relevance of the structured query associated with the respective reaction-card to the geographic location.
