Abstract

Systems, methods, and non-transitory computer-readable media can determine a geographical area associated with a crisis. A first user within the geographical area can be identified based on locational data associated with the first user. Information about a safety status of the first user can be actively requested or acquired from the first user. The safety status of the first user can be broadcasted, communicated, or provided to at least a second user associated with the first user.

First claim

What is claimed is:

1. A computer-implemented method comprising:
identifying, by a computing system, in a crawl process a first user and a connected user associated with the first user within a geographical area associated with a crisis;
requesting, by the computing system, a safety status of the connected user within the geographical area;
providing, by the computing system, the safety status of the connected user within the geographical area through at least a portion of a network;
generating, by the computing system, a probability metric relating to potential expansion of the crawl process to a connection who is not within the geographical area associated with the crisis but who is connected to the connected user; and
based on satisfaction by the probability metric of a threshold, expanding, by the computing system, the crawl process to the connection not within the geographical area so that the safety status of the connection is requested and broadcasted.

2. The computer-implemented method of claim 1 , wherein the connected user within the geographical area is associated with a first pocket of persons in the geographical area.

3. The computer-implemented method of claim 2 , wherein the connection is connected to a second pocket of persons in the geographical area that is not connected through the geographical area to the first pocket of persons.

4. The computer-implemented method of claim 3 , wherein the second pocket of persons includes a second user, the method further comprising:
requesting a safety status of the second user; and
providing the safety status of the second user through at least a portion of the network.

5. The computer-implemented method of claim 1 , further comprising:
generating a second probability metric associated with a second connection of the connected user, the second connection not within the geographical area associated with the crisis;
not expanding the crawl process to the second connection not within the geographical area based on non-satisfaction by the second probability metric of the threshold.

6. The computer-implemented method of claim 1 , wherein the probability metric is a random probability metric.

7. The computer-implemented method of claim 6 , wherein the random probability metric is a decimal value between zero and 1.

8. The computer-implemented method of claim 1 , wherein the threshold is an adjustable probabilistic threshold level associated with expansiveness of the crawl process.

9. The computer-implemented method of claim 1 , wherein the identifying the first user and the connected user comprises determining a set of users including the first user and the connected user who are refreshing feed data.

10. The computer-implemented method of claim 1 , wherein the geographical area includes at least one of a district, a zip code area, a city, a county, a region, a state, a province, and a country.

11. A system comprising:
at least one processor; and
a memory storing instructions that, when executed by the at least one processor, cause the system to perform:
identifying in a crawl process a first user and a connected user associated with the first user within a geographical area associated with a crisis;
requesting a safety status of the connected user within the geographical area;
providing the safety status of the connected user within the geographical area through at least a portion of a network;
generating a probability metric relating to potential expansion of the crawl process to a connection who is not within the geographical area associated with the crisis but who is connected to the connected user; and
based on satisfaction by the probability metric of a threshold, expanding the crawl process to the connection not within the geographical area so that the safety status of the connection is requested and broadcasted.

12. The system of claim 11 , wherein the connected user within the geographical area is associated with a first pocket of persons in the geographical area.

13. The system of claim 12 , wherein the connection is connected to a second pocket of persons in the geographical area that is not connected through the geographical area to the first pocket of persons.

14. The system of claim 11 , wherein the probability metric is a random probability metric.

15. The system of claim 11 , the identifying the first user and the connected user comprises determining a set of users including the first user and the connected user who are refreshing feed data.

16. A non-transitory computer-readable storage medium including instructions that, when executed by at least one processor of a computing system, cause the computing system to perform:
identifying in a crawl process a first user and a connected user associated with the first user within a geographical area associated with a crisis;
requesting a safety status of the connected user within the geographical area;
providing the safety status of the connected user within the geographical area through at least a portion of a network;
generating a probability metric relating to potential expansion of the crawl process to a connection who is not within the geographical area associated with the crisis but who is connected to the connected user; and
based on satisfaction by the probability metric of a threshold, expanding the crawl process to the connection not within the geographical area so that the safety status of the connection is requested and broadcasted.

17. The non-transitory computer-readable storage medium of claim 16 , wherein the connected user within the geographical area is associated with a first pocket of persons in the geographical area.

18. The non-transitory computer-readable storage medium of claim 17 , wherein the connection is connected to a second pocket of persons in the geographical area that is not connected through the geographical area to the first pocket of persons.

19. The non-transitory computer-readable storage medium of claim 16 , wherein the probability metric is a random probability metric.

20. The non-transitory computer-readable storage medium of claim 16 , the identifying the first user and the connected user comprises determining a set of users including the first user and the connected user who are refreshing feed data.
