Abstract

Mechanisms are provided that: identify topics associated with a plurality of pieces of media content presented in a session; calculate a distance metric for pairs of topics, wherein each of the pairs of topics includes a first topic associated with a first piece of media content and a second topic associated with a second piece of media content, and wherein the second piece of media content was presented within a given span of the presentation of the first piece of media content; for each first topic of the pairs of topics, generate a rank-ordered list for all corresponding second topics; for each of the plurality of pieces of media content, generate a single rank-ordered list of all second topics; and for each of the plurality of pieces of media content, identify one or more other pieces of media content as recommended media content based on the single rank-ordered list.

First claim

What is claimed is:

1. A system for recommending media content, the system comprising:
at least one hardware processor configured to:
determine that a session including presentation of at least a first media content item and a second media content item is likely to have ended, wherein the second media content item is presented within a given span of the presentation of the first media content item;
in response to determining that the session is likely to have ended, determine a first plurality of topics associated with the first media content item and the second media content item;
determine a second plurality of topics associated with the media content presentation session based on distance information for pairs of topics in the first plurality of topics, wherein each of the pairs of topics includes a first topic associated with the first media content item and a second topic associated with the second media content item; and
transmit an indication of a plurality of media content items that correspond to at least a portion of the second plurality of topics.

2. The system of claim 1 , wherein the at least one hardware processor is further configured to select the first media content item and the second media content item from media content search results that are responsive to search terms.

3. The system of claim 1 , wherein the distance information is a mutual information score.

4. The system of claim 1 , wherein the given span is two adjacent presentations.

5. The system of claim 1 , wherein the at least one hardware processor is further configured to, for each of the first media content item and the second media content item, generate a single rank-ordered list of the second plurality of topics.

6. The system of claim 5 , wherein the at least one hardware processor is further configured to, for each of the first media content item and the second media content item, identify the plurality of media content items as recommended media content items based on the single rank-ordered list.

7. The system of claim 6 , wherein the single rank-ordered list of the second plurality of topics generated for the first media content item and the second media content item is generated by:
(a) determining topics associated with the first media content item and the second media content item;
(b) for each of the topics, obtaining a rank-ordered list of second topics generated for the topic as the first topic; and
(c) combining all of the rank-ordered lists obtained at (b) together using the distance information as ranking score to form the single rank-ordered list.

8. A method for recommending media content, comprising:
determining, using a hardware processor, that a session including presentation of at least a first media content item and a second media content item is likely to have ended, wherein the second media content item is presented within a given span of the presentation of the first media content item;
in response to determining that the session is likely to have ended, determining, using the hardware processor, a first plurality of topics associated with the first media content item and the second media content item;
determining, using the hardware processor, a second plurality of topics associated with the media content presentation session based on distance information for pairs of topics in the first plurality of topics, wherein each of the pairs of topics includes a first topic associated with the first media content item and a second topic associated with the second media content item; and
transmitting, using the hardware processor, an indication of a plurality of media content items that correspond to at least a portion of the second plurality of topics.

9. The method of claim 8 , further comprising selecting the first media content item and the second media content item from media content search results that are responsive to search terms.

10. The method of claim 8 , wherein the distance information is a mutual information score.

11. The method of claim 8 , wherein the given span is two adjacent presentations.

12. The method of claim 8 , further comprising, for each of the first media content item and the second media content item, generating a single rank-ordered list of the second plurality of topics.

13. The method of claim 12 , further comprising, for each of the first media content item and the second media content item, identifying the plurality of media content items as recommended media content items based on the single rank-ordered list.

14. The method of claim 13 , wherein the single rank-ordered list of the second plurality of topics generated for the first media content item and the second media content item is generated by:
(a) determining topics associated with the first media content item and the second media content item;
(b) for each of the topics, obtaining a rank-ordered list of second topics generated for the topic as the first topic; and
(c) combining all of the rank-ordered lists obtained at (b) together using the distance information as ranking score to form the single rank-ordered list.

15. A non-transitory computer-readable medium containing computer-executable instructions that, when executed by a processor, cause the processor to perform a method for recommending media content, the method comprising:
determining that a session including presentation of at least a first media content item and a second media content item is likely to have ended, wherein the second media content item is presented within a given span of the presentation of the first media content item;
in response to determining that the session is likely to have ended, determining a first plurality of topics associated with the first media content item and the second media content item;
determining a second plurality of topics associated with the media content presentation session based on distance information for pairs of topics in the first plurality of topics, wherein each of the pairs of topics includes a first topic associated with the first media content item and a second topic associated with the second media content item; and
transmitting an indication of a plurality of media content items that correspond to at least a portion of the second plurality of topics.

16. The non-transitory computer-readable medium of claim 15 , wherein the method further comprises selecting the first media content item and the second media content item from media content search results that are responsive to search terms.

17. The non-transitory computer-readable medium of claim 15 , wherein the distance information is a mutual information score.

18. The non-transitory computer-readable medium of claim 15 , wherein the given span is two adjacent presentations.

19. The non-transitory computer-readable medium of claim 15 , wherein the method further comprises, for each of the first media content item and the second media content item, generating a single rank-ordered list of the second plurality of topics.

20. The non-transitory computer-readable medium of claim 19 , wherein the method further comprises, for each of the first media content item and the second media content item, identifying the plurality of media content items as recommended media content items based on the single rank-ordered list.

21. The non-transitory computer-readable medium of claim 20 , wherein the single rank-ordered list of the second plurality of topics generated for the first media content item and the second media content item is
