Abstract

In one embodiment, a method includes detecting that a first set of users associated with an emergency event have posted content related to the emergency event on an online social network. The method may also include sending a safety-check prompt to each of one or more users in the first set. The method may also include determining a current-prompting probability based on one or more engagement metrics of the one or more users in the first set. The method may also include sending, in response to determining that the current-prompting probability is above a threshold probability, the safety-check prompt to each of a second set of users. The second set of users may have more users than the first set of users.

First claim

What is claimed is:

1. A method comprising:
by a computing device, detecting that a first set of users associated with an emergency event have posted content related to the emergency event on an online social network;
by the computing device, sending a safety-check prompt to each of one or more users in the first set of users;
by the computing device, determining a current-prompting probability based on one or more engagement metrics of the one or more users in the first set of users; and
by the computing device, sending, in response to determining that the current-prompting probability is above a threshold probability, the safety-check prompt to each of a second set of users, wherein the second set of users comprises more users than the first set of users.

2. The method of claim 1 , further comprising sending, in response to determining that the current-prompting probability is above a second threshold probability, the safety-check prompt to each of a third set of users, wherein the third set of users comprises more users than the second set of users and the second threshold probability is higher than the first threshold probability.

3. The method of claim 1 , wherein the safety-check prompt comprises one or more selectable icons that enable a user to indicate a safety status associated with the user.

4. The method of claim 1 , wherein identifying an emergency event comprises classifying, based on one or more emergency metrics, a plurality of items on an alert feed as either a qualifying emergency or as a non-qualifying emergency.

5. The method of claim 1 , wherein the current-prompting probability is determined at regular intervals.

6. The method of claim 1 , wherein the one or more engagement metrics comprise:
a number of users in the first set of users who have interacted with the safety-check prompt;
a number of users in the first set of users who have ignored or hid the safety-check prompt; or
a number of impressions of the safety-check prompt.

7. The method of claim 1 , wherein detecting that the first set of users associated with the emergency event have posted content related to the emergency event on the online social network comprises:
extracting one or more text strings from the posted content; and
applying a natural language analysis to determine that the text strings comprise one or more n-grams that are related to the emergency event.

8. The method of claim 1 , wherein the emergency event is associated with a particular geographic location, and each user in the first set of users and each user in the second set of users is also associated with the particular geographic location.

9. The method of claim 1 , wherein sending the safety check prompt to each of the one or more users in the first set of users comprises sending the safety check prompt to a random selection of users within the first set of users.

10. One or more computer-readable non-transitory storage media embodying software that is operable when executed to:
detect that a first set of users associated with an emergency event have posted content related to the emergency event on an online social network;
send a safety-check prompt to each of one or more users in the first set of users;
determine a current-prompting probability based on one or more engagement metrics of the one or more users in the first set of users; and
send, in response to determining that the current-prompting probability is above a threshold probability, the safety-check prompt to each of a second set of users, wherein the second set of users comprises more users than the first set of users.

11. The media of claim 10 , wherein the software is further operable when executed to send, in response to determining that the current-prompting probability is above a second threshold probability, the safety-check prompt to each of a third set of users, wherein the third set of users comprises more users than the second set of users and the second threshold probability is higher than the first threshold probability.

12. The media of claim 10 , wherein the safety-check prompt comprises one or more selectable icons that enable a user to indicate a safety status associated with the user.

13. The media of claim 10 , wherein identifying an emergency event comprises classifying, based on one or more emergency metrics, a plurality of items on an alert feed as either a qualifying emergency or as a non-qualifying emergency.

14. The media of claim 10 , wherein the current-prompting probability is determined at regular intervals.

15. The media of claim 10 , wherein the one or more engagement metrics comprise:
a number of users in the first set of users who have interacted with the safety-check prompt;
a number of users in the first set of users who have ignored or hid the safety-check prompt; or
a number of impressions of the safety-check prompt.

16. The media of claim 10 , wherein the emergency event is associated with a particular geographic location, and each user in the first set of users and each user in the second set of users is also associated with the particular geographic location.

17. 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:
detect that a first set of users associated with an emergency event have posted content related to the emergency event on an online social network;
send a safety-check prompt to each of one or more users in the first set of users;
determine a current-prompting probability based on one or more engagement metrics of the one or more users in the first set of users; and
send, in response to determining that the current-prompting probability is above a threshold probability, the safety-check prompt to each of a second set of users, wherein the second set of users comprises more users than the first set of users.

18. The system of claim 17 , wherein the processors are further operable when executing the instructions to send in response to determining that the current-prompting probability is above a second threshold probability, the safety-check prompt to each of a third set of users, wherein the third set of users comprises more users than the second set of users and the second threshold probability is higher than the first threshold probability.

19. The system of claim 17 , wherein the safety-check prompt comprises one or more selectable icons that enable a user to indicate a safety status associated with the user.

20. The system of claim 17 , wherein the current-prompting probability is determined at regular intervals.
