Abstract

A computer implemented method and system that generates a video playlist having recommended videos based on a user query object is disclosed. A user query object is used to search for a number of web pages. Summaries are generated for the returned web page search results. Valuable terms and phrases from those summaries may be extracted and used to search video storage sites based on the original user query. Playable videos returned from the video storage sites may be compared to the user query or to the extracted terms and phrases in order to rank the videos, and the most relevant videos may be returned. Those videos may be displayed to the user as a playlist in an Internet browser having an embedded video player.

Claims

1. A computer system for returning a list of playable media objects to a user, comprising:

a server configured to receive a search query object from the user;

a first module configured to;

identify additional terms related to the search query object by providing the search query object to at least one internet search engine and processing results returned by the internet search engine, wherein processing includes;

receiving a page identified in the result returned by the internet search engine,

parsing the received page to extract terms from the page and identify sections in the page,

generating relationship vectors based on the extracted terms,

scoring sections of the received page based on the generated relationship vectors, and

selecting additional terms based at least in part on the scores; and

a second module configured to query one or more video storage web sites based on the identified additional terms to obtain a list of playable media objects stored on the one or more video storage web sites, the playable media objects comprising the identified additional terms.

2. The computer system of claim 1, wherein the list of playable media objects comprises a list of links to the playable media objects configured to be played in an internet browser.

3. The computer system of claim 1, further comprising a third module configured to play the playable media objects in an internet browser.

4. The computer system of claim 1, wherein the second module is configured to rank playable media objects based at least in part on the identified additional terms.

5. The computer system of claim 1, wherein at least one of the identified additional terms comprises a multi-word phrase contextually related to the search query object.

6. The computer system of claim 1, wherein the identified additional terms are ranked based on their contextual relationship with the search query object.

7. The computer system of claim 6, wherein the identified additional terms are ranked based at least in part on a relationship network corresponding to search query object.

8. The computer system of claim 7, wherein the relationship network is generated from a pre-existing knowledgebase.

9. The computer system of claim 7, wherein the relationship network is generated by comparing a pre-existing knowledge base with the search query object.

10. The computer system of claim 1, wherein the second module is further configured to query a plurality of the video storage web sites in order to generate the list of playable media objects, and wherein the second module is configured to aggregate the query results and rank the query results in the list of playable media objects.

11. The computer system of claim 1, wherein the playable media objects comprise playable videos.

12. A computer implemented method of generating a list of playable media objects, the method comprising the steps of:

receiving a search query object;

querying at least one internet search engine with the search query object;

generating additional terms related to the search query object based on results returned by the internet search engine, further comprising;

receiving a page identified in the result returned by the internet search engine,

parsing the received page to extract terms from the page and identify sections in the page,

generating relationship vectors based on the extracted terms,

scoring sections of the received page based on the generated relationship vectors, and

selecting additional terms based at least in part on the scores; and

identifying media storage web sites having playable media objects related to the generated additional terms; and

generating a list of playable media objects from the playable media objects at the media storage web sites.

13. The method of claim 12, further comprising providing links to the playable media objects in the list of playable media objects.

14. The method of claim 12, further comprising transmitting the listed playable media objects in response to a user request.

15. The method of claim 12, wherein the additional terms are ranked.

16. The method of claim 12, wherein identifying media storage web sites comprises extracting metadata corresponding to the playable media objects and comparing the additional terms to the extracted metadata.

17. The method of claim 16, wherein the metadata comprises at least one type of data selected from the group of:

a title, a summary, a playtime, a genre, a rating, a creation date, an artist, and a script.

18. The method of claim 12, further comprising ranking the playable media objects.

19. The method of claim 18, wherein ranking the playable media objects comprises:

extracting external tags from the media objects; and

comparing the external tags to the generated additional terms.
