Abstract

Associating a content item with an event is disclosed. A location associated with a received content item is determined. The received content item is associated with an event, at least in part based on an indicia of relatedness, other than the determined location, between the received content item and the event. A criterion that the indicia of relatedness is required to satisfy for the content item to be determined to be associated with the event has a lower value if the determined location associated with the received content item has a first degree of correspondence to a location associated with the event than if the determined location associated with the received content item has a second, lower degree of correspondence to the location associated with the event.

Claims

1. A method for associating a content item with an event, comprising:

determining a location associated with a received content item; and

associating the received content item with an event, at least in part based on an indicia of relatedness, other than the determined location, between the received content item and the event;

wherein a criterion that the indicia of relatedness is required to satisfy for the content item to be determined to be associated with the event has a lower value

if the determined location associated with the received content item has a first degree of correspondence to a location associated with the event than

if the determined location associated with the received content item has a second, lower degree of correspondence to the location associated with the event.

2. A method as in claim 1, wherein the indicia of relatedness comprises a bi-gram overlap.

3. A method as in claim 2, wherein the bi-gram overlap comprises a frequency based overlap between bi-grams associated with the received content item and bi-grams associated with a content item associated with the event.

4. A method as in claim 1, wherein the indicia of relatedness comprises a unigram similarity.

5. A method as in claim 4, wherein the unigram similarity comprises a similarity between unigrams associated with the received content item and unigrams associated with a content item associated with the event.

6. A method as in claim 1, wherein the indicia of relatedness comprises an entity overlap.

7. A method as in claim 6, wherein an entity overlap comprises a frequency based overlap between named entities associated with the received content item and named entities associated with a content item associated with the event.

8. A method as in claim 1, wherein the criterion for the indicia of relatedness comprises a matching threshold.

9. A method as in claim 1, wherein the indicia of relatedness includes a time overlap between a time associated with the received content item and a time associated with the event.

10. A method as in claim 9, wherein the time overlap comprises being within a 24 hour window.

11. A method as in claim 1, wherein the event is one of a plurality of candidate events determined at least in part using one or more prior received content items.

12. A method as in claim 11, wherein the plurality of candidate events are each assigned a rating based on weightings of indicia of similarity between the content item and the one or more prior received content items associated with each of the plurality of candidate event as well as a number of the one or more prior received content items associated with a given candidate event.

13. A system for associating a content item with an event, comprising:

a location determiner for determining a location associated with a received content item; and

a content item associater for associating the received content item with an event, at least in part based on an indicia of relatedness, other than the determined location, between the received content item and the event;

wherein a criterion that the indicia of relatedness is required to satisfy for the content item to be determined to be associated with the event has a lower value

if the determined location associated with the received content item has a first degree of correspondence to a location associated with the event than

if the determined location associated with the received content item has a second, lower degree of correspondence to the location associated with the event.

14. A computer program product for associating a content item with an event, the computer program product being embodied in a computer readable storage medium and comprising computer instructions for:

determining a location associated with a received content item; and

associating the received content item with an event, at least in part based on an indicia of relatedness, other than the determined location, between the received content item and the event;

wherein a criterion that the indicia of relatedness is required to satisfy for the content item to be determined to be associated with the event has a lower value

if the determined location associated with the received content item has a first degree of correspondence to a location associated with the event than

if the determined location associated with the received content item has a second, lower degree of correspondence to the location associated with the event.

15. A method for processing a received content item, comprising:

determining a location associated with the received content item;

determining an event that is associated with the received content item; and

revising, if appropriate, a location associated with the event based at least in part on the location associated with the content item.

16. A method as in claim 15, further comprising listing the event at the location associated with the event.

17. A method as in claim 15, wherein determining a location associated with the received content item includes using an extraction pattern.

18. A method as in claim 17, wherein the extraction pattern is associated with one or more of the following:

a byline, a “

to”

reference, a “

from”

reference, an “

at”

reference, an “

in”

reference, a colon receding, a colon succeeding, or all capital letters within parentheses.

19. A method as in claim 17, wherein the extraction pattern is associated with a weight corresponding to confidence.

20. A method as in claim 15, wherein determining a location associated with the received content item comprises building a list of possible locations.

21. A method as in claim 20, wherein the list includes a plurality of entries comprising a location associated with the content item and a weight associated with the location.

22. A method as in claim 15, wherein determining a location associated with the received content item comprises assigning the location associated with the received content item to a location of associated with a source of the content item.

23. A system for processing a received content item, comprising:

A location determiner for determining a location associated with the received content item;

An event determiner for determining an event that is associated with the received content item; and

A location reviser for revising, if appropriate, a location associated with the event based at least in part on the location associated with the content item.

24. A method for associating a content item with an event, comprising:

determining a location associated with a received content item; and

associating the received content item with an event based at least in part on the determined location and on other indicia of relatedness.

25. A method as in claim 24, wherein associating the received content item with the event includes computing a joint function of location overlap and other indicia overlap.

27. A method as in claim 25, wherein the similarity statistic comprises a term frequency inverse document frequency statistic.

28. A method as in claim 25, wherein the event category comprises one of the following:

politics, entertainment, sports, science, technology, conflict, tragedy, business, health, elections, local, national, foreign, or world.

26. A method for processing a content item, comprising:

determining an event category associated with a content item;

computing a similarity statistic for one or more terms of the content item using a statistical model associated with the event category.
