Detecting associates
View Patent ↗Detecting, for a content item, associated preference events is disclosed. For the content item, a plurality of preference events from a plurality of users is received. The received preference events are accumulated. Associated events are detected. The effect of the events is reduced when assigning a status to the item.
1. A method of identifying a cohort of users attempting to orchestrate preference events for content items, at a preference system for presenting the content items to users, the method comprising:
receiving from a plurality of users preference events regarding multiple content items; and
for at least one of the plurality of users, operating a processor to:
identify a set of content items for which the user initiated preference events of a first type;
for each of the identified content items, identify other users in the plurality of users, if any, that initiated preference events of the first type for the content item; and
if multiple users amounting to at least a first percentage of users in the plurality of users initiated preference events of the first type for a subset of content items amounting to at least a second percentage of the set of content items:
record the multiple users as a cohort; and
reduce effects of the preference events initiated by the cohort when determining statuses to assign the subset of content items.
2. The method of claim 1 , wherein identifying a set of content items for which the user initiated preference events of a first type comprises:
constructing a data table comprising:
a column corresponding to each user in the plurality of users; and
a row corresponding to each content item in the set of content items; and
in the data table column corresponding to the user, in each cell corresponding to a content item for which the user initiated a preference event of the first type:
storing identifications of all other users in the plurality of users that initiated a preference event of the first type for the same content item.
3. The method of claim 2 , further comprising:
determining whether multiple users amounting to at least a first percentage of users in the plurality of users initiated preference events of the first type for a subset of content items amounting to at least a second percentage of the set of content items by:
identifying, in the data table column corresponding to the user, each cell that contains a number of identifications of other users equal to or greater than the first percentage; and
for each identified cell, determining whether the identifications stored in the identified cell are stored together in a total number of cells in the data table column equal to or greater than the second percentage.
4. The method of claim 1 , wherein the plurality of users comprises a first user of the preference system and all associates of the first user known to the preference system.
5. The method of claim 1 , wherein the plurality of users comprises a first user of the preference system and all other users of the preference system identified as friends of the first user.
6. The method of claim 1 , wherein preference events comprise:
a positive preference event; and
a negative preference event.
7. The method of claim 6 , wherein:
a positive preference event is a digg; and
a negative preference event is a bury.
8. The method of claim 1 , wherein:
the first percentage is approximately 50%; and
the second percentage is approximately 20%.
9. The method of claim 1 , wherein reducing effects of the preference events comprises:
increasing scores associated with the subset of content items when determining statuses to assign the subset of content items.
10. The method of claim 1 , wherein reducing effects of the preference events comprises:
decreasing scores associated with the subset of content items when determining statuses to assign the subset of content items.
11. The method of claim 1 , wherein reducing effects of the preference events comprises:
discarding the preference events when determining statuses to assign the subset of content items.
12. A computer program product for identifying, at a preference system, a cohort of users attempting to orchestrate preference events for content items for presenting the content items to users, the computer program product being embodied in a non-transitory computer readable storage medium and comprising instructions for:
receiving from a plurality of users preference events regarding multiple content items; and
for at least one of the plurality of users:
identifying a set of content items for which the user initiated preference events of a first type;
for each of the identified content items, identifying other users in the plurality of users, if any, that initiated preference events of the first type for the content item; and
if multiple users amounting to at least a first percentage of users in the plurality of users initiated preference events of the first type for a subset of content items amounting to at least a second percentage of the set of content items:
recording the multiple users as a cohort; and
reducing effects of the preference events initiated by the cohort when determining statuses to assign the subset of content items.
13. A preference system for identifying a cohort of users attempting to orchestrate preference events for content items, the system including:
a processor; and
a memory coupled with the processor, wherein the memory is configured to provide the processor with instructions that, when executed, cause the processor to:
receive from a plurality of users preference events regarding multiple content items; and
for at least one of the plurality of users:
identify a set of content items for which the user initiated preference events of a first type;
for each of the identified content items, identify other users in the plurality of users, if any, that initiated preference events of the first type for the content item; and
if multiple users amounting to at least a first percentage of users in the plurality of users initiated preference events of the first type for a subset of content items amounting to at least a second percentage of the set of content items:
record the multiple users as a cohort; and
reduce effects of the preference events initiated by the cohort when determining statuses to assign the subset of content items.
14. The system of claim 13 , wherein identifying a set of content items for which the user initiated preference events of a first type comprises:
constructing a data table comprising:
a column corresponding to each user in the plurality of users; and
a row corresponding to each content item in the set of content items; and
in the data table column corresponding to the user, in each cell corresponding to a content item for which the user initiated a preference event of the first type:
storing identifications of all other users in the plurality of users that initiated a preference event of the first type for the same content item.
15. The system of claim 14 , wherein the memory is further configured to provide the processor with instructions that, when executed, cause the processor to:
determine whether multiple users amounting to at least a first percentage of users in the plurality of users initiated preference events of the first type for a subset of content items amounting to at least a second percentage of the set of content items by:
identifying, in the data table column corresponding to the user, each cell that contains a number of identifications of other users equal to or greater than the first percentage; and
for each identified cell, determining whether the identifications stored in the identified cell are stored together in a total number of cells in the data table column equal to or greater than the second percentage.
16. The system of claim 13 , wherein the plurality of users comprises a first user of the preference system and all associates of the first user known to the preference system.
17. The system of claim 13 , wherein the plurality of users comprises a first user of the preference system and all other users of the preference system identified as friends of the first user.
18. The system of claim 13 , wherein reducing effects of the preference events comprises:
discarding the preference events when determining statuses to assign the subset of content items.
19. The system of claim 13 , wherein preference events comprise:
a positive preference event; and
a negative preference event.
