Abstract

Systems and methods for clustering news information are disclosed. The news information is clustered to form clusters to include one or more of articles, blogs, images, videos and the like. The news information is organized according to topic and/or temporal information. The clustered news information can be presented to a user who can browse or search the clustered news information.

Claims

1. A computer-implemented method for presenting information comprising:

receiving textual news information;

clustering the textual news information to form a plurality of topic clusters;

identifying textual information associated with visual news information;

associating visual news information with at least one of the plurality of topic clusters using the textual information;

providing the visual news information with the at least one of the plurality of topic clusters.

2. The method of claim 1, wherein the textual news information comprises news articles.

3. The method of claim 1, wherein the textual news information comprises blog articles.

4. The method of claim 1, wherein the visual news information comprises images.

5. The method of claim 1, wherein the visual news information comprises videos.

6. The method of claim 1, wherein the textual information comprises metadata.

7. The method of claim 5, wherein identifying textual information associated with visual news information comprises converting audio data of the video to textual information.

8. The method of claim 7, further comprising ranking the plurality of topic clusters.

9. The method of claim 7, further comprising ranking the textual news information in each of the plurality of topic clusters.

21. The method of claim 8, wherein ranking comprises considering one or more of:

a number of different groups of very near duplicates in the cluster, a number of distinct news sources in the cluster, importance of the news sources in the cluster as observed by their past production of important articles or by editorial choices, a number of news articles produced by sources in the same country of the engine, a freshness of the articles in the cluster, a number of images associated with the cluster, a number of videos associated with the cluster, a number of blogs associated with the news cluster, a number of entities associated with a cluster, a length of the chain associated with the cluster, and a number of comments posted by users to the articles in the cluster.

10. A computer-implemented method for organizing related news information comprising:

receiving differing news information types;

merging the differing news information types to form merged news information;

clustering the merged news information to form a plurality of topic clusters; and

providing the plurality of topic clusters,

wherein the differing news information types are selected from the group consisting of articles, blogs, images and videos.

11. The method of claim 10, wherein merging differing news information types to form merged news information comprises merging articles and blogs.

12. The method of claim 11, further comprising associating a multimedia object with the topic clusters.

13. The method of claim 12, wherein the multimedia object is selected from the group consisting of images, videos and combinations thereof.

14. A search system comprising:

a news information receiver to receive news information, wherein the news information comprises textual information and multimedia objects;

a merging unit to merge the textual news information; and

a cluster unit to cluster the textual news information according to a topic of the news information.

15. The search system of claim 14, further comprising a server to present the news information to a user.

16. The search system of claim 15, further comprising a search engine connected to the server, the search engine to receive a search query of the news information.

17. The search system of claim 16, wherein the server is to provide a search result to the search engine in response to the search query.

18. The search system of claim 14, further comprising a ranking unit to rank clustered news information.

19. The search system of claim 14, further comprising an associating unit to associate the multimedia objects with the clustered news information according to the topic of the news information.

20. The search system of claim 19, wherein the multimedia objects are selected from the group consisting of images, videos and combinations thereof.

22. The search system of claim 18, wherein the ranking unit is to consider one or more of:

a number of different groups of very near duplicates in the cluster, a number of distinct news sources in the cluster, importance of the news sources in the cluster as observed by their past production of important articles or by editorial choices, a number of news articles produced by sources in the same country of the engine, a freshness of the articles in the cluster, a number of images associated with the cluster, a number of videos associated with the cluster, a number of blogs associated with the news cluster, a number of entities associated with a cluster, a length of the chain associated with the cluster, and a number of comments posted by users to the articles in the cluster.
