Displaying a summary of media content items

1. A method, comprising:

at a server system having one or more processors and memory storing one or more programs for execution by the one or more processors:

detecting presentation of a media content item at a first client device in proximity to a second client device, including receiving from the second client device content information derived from sound output from the presentation of the media content item at the first client device captured by the second client device;

maintaining at the server system a media content identification database comprising a collection of audio content fingerprints generated from audio content of a plurality of media content items;

identifying the media content item by matching the content information to the audio content fingerprints in the media content identification database;

identifying a plurality of entities related to the identified media content item, wherein each of the identified plurality of entities corresponds to a respective proper noun associated with the media content item;

for each of the identified plurality of entities, determining a level of interest with respect to a user of the second client device and a level of aggregate interest, wherein the level of aggregate interest is determined based on one or more aggregated signals of interest from a plurality of users, and the level of interest with respect to the user of the second client device is determined based on one or more signals of interest from the user of the second client device;

selecting a subset of the identified plurality of entities based on the determined levels of interest with respect to the user of the second client device and the determined levels of aggregate interest; and

sending to the second client device, for presenting at the second client device, a summary of the media content item, the summary comprising a listing of the selected subset of the identified plurality of entities.

2. The method of claim 1 , wherein the one or more aggregated signals of interest from the plurality of users comprise one or more of:

a volume of mentions of the entity in documents, a volume of queries for the entity, a volume of queries for the media content item, an aggregate of query histories of users, and an aggregate of histories of media consumption by users.

3. The method of claim 1 , wherein the one or more signals of interest from the user of the second client device comprise one or more of: a location of the user of the second client device, demographic characteristics of the user of the second client device, a query history of the user of the second client device, and a media consumption history of the user of the second client device.

4. A method, comprising:

at a server system having one or more processors and memory storing one or more programs for execution by the one or more processors:

detecting presentations of a plurality of media content items at a plurality of client devices, including receiving content information corresponding to the presentations of the plurality of media content items at the plurality of client devices;

maintaining at the server system a media content identification database comprising a collection of audio content fingerprints generated from audio content of a corpus of media content items including the plurality of media content items;

identifying the plurality of media content items by matching the content information to the audio content fingerprints in the media content identification database;

for each of the plurality of media content items:

identifying a plurality of entities related to the media content item, wherein each of the identified plurality of entities corresponds to a respective proper noun associated with the media content item, and

for each of the plurality of entities identified for the media content item, determining a level of aggregate interest with respect to a defined time period based on one or more aggregated signals of interest from a plurality of users;

selecting a subset of the entities identified for the plurality of media content items based on the determined levels of aggregate interest with respect to the defined time period; and

sending to a client device, for presenting at the client device, a summary of the plurality of media content items, the summary comprising a listing of the selected subset of the entities identified for the plurality of media content items.

5. The method of claim 4 , wherein the defined time period is any of: a defined hour, a defined day, a defined month, or a defined time range.

6. A server system, comprising:

memory;

one or more processors; and

one or more programs stored in the memory and configured for execution by the one or more processors, the one or more programs including instructions for:

detecting presentation of a media content item at a first client device in proximity to a second client device, including receiving from the second client device content information derived from sound output from the presentation of the media content item at the first client device captured by the second client device;

maintaining at the server system a media content identification database comprising a collection of audio content fingerprints generated from audio content of a plurality of media content items;

identifying the media content item by matching the content information to the audio content fingerprints in the media content identification database;

identifying a plurality of entities related to the identified media content item, wherein each of the identified plurality of entities corresponds to a respective proper noun associated with the media content item;

for each of the identified plurality of entities, determining a level of interest with respect to a user of the second client device and a level of aggregate interest, wherein the level of aggregate interest is determined based on one or more aggregated signals of interest from a plurality of users, and the level of interest with respect to the user of the second client device is determined based on one or more signals of interest from the user of the second client device;

selecting a subset of the identified plurality of entities based on the determined levels of interest with respect to the user of the second client device and the determined levels of aggregate interest; and

sending to the second client device, for presenting at the second client device, a summary of the media content item, the summary comprising a listing of the selected subset of the identified plurality of entities.

7. The system of claim 6 , wherein the one or more aggregated signals of interest from the plurality of users comprise one or more of:

a volume of mentions of the entity in documents, a volume of queries for the entity a volume of queries for the media content item, an aggregate of query histories of users, and an aggregate of histories of media consumption by users.

8. The system of claim 6 , wherein the one or more signals of interest from the user of the second client device comprise one or more of: a location of the user of the second client device, demographic characteristics of the user of the second client device, a query history of the user of the second client device, and a media consumption history of the user of the second client device.
