Abstract

The present invention provides a hypermedia database for managing bookmarks, which allows a user to organize hypertext documents for querying, navigating, sharing and viewing. In addition, the hypermedia database also provides access control to the information in the database. The hypermedia database of the present invention parses meta-data from bookmarked documents and indexes and classifies the documents. The present invention supports advanced query and navigation of a collection of bookmarks, especially providing various personalized bookmark services. In one embodiment, the present invention utilizes a proxy server to observe a user'"'"'s access patterns to provide useful personalized services, such as automated URL bookmarking, document refresh, and bookmark expiration. In addition, a user may also specify various preference in bookmark management, e.g., ranking schemes (i.e. by referral, access frequency, or popularity) and navigation tree fan-out. A subscription service which retrieves new or updated documents of user-specified interests is also provided.

Claims

1. A bookmark system having access to a computer network, comprising:

an interface to said computer network;

a database management system;

a bookmark management system coupled to said database and said interface, said bookmark management system creating and maintaining in said database a document record containing information for locating a document in said computer network, and for retrieving said document from said computer network over said interface using said information for locating a document wherein said bookmark management system associates, for each owner, said document record with an owner-specific record and wherein said bookmark management system associates, for each user, said document record with a user-specific record.

2. A bookmark system as in claim 1, further comprising a document classification system for associating said document into one or more categories.

3. A bookmark system as in claim 2, wherein said document classification system accesses an a classifier program on said computer network through said interface.

4. A bookmark system as in claim 2, wherein said categories are leaf nodes of a hierarchical classification trees.

5. A bookmark system as in claim 2, wherein said database system accesses a lexical dictionary for retrieving a list of keywords relating to a document.

6. A bookmark system as in claim 2, wherein each of said categories is a node of a navigation tree.

7. A bookmark system as in claim 6, wherein, in said navigation tree, each category includes less than a predetermined number of documents.

8. A bookmark system as in claim 7, wherein said navigation tree is grown by providing child nodes to an existing node when said predetermined number of documents is exceeded in the category corresponding to said existing node.

9. A bookmark system as in claim 1 wherein said interface couples to a proxy server coupled to said computer network.

10. A bookmark system as in claim 9, wherein said proxy server monitors, for each user, an access frequency for said document.

11. A bookmark system as in claim 10, wherein said bookmark management system automatically associates identification information of a user with a document record when said access frequency of a user exceeds a predetermined number.

12. A bookmark system as in claim 10, wherein said bookmark management system calculates for said document a page rank, said page rank being a function of said access frequency and a quantity related to documents referenced by said document or referencing said document.

13. A bookmark system as in claim 12, wherein said function is a product.

14. A bookmark system as in claim 10, wherein said bookmark management system associates with said document record an access pattern of said document.

15. A bookmark system as in claim 1, wherein said owner-specific record indicates whether information on said owner-specific record is shared.

16. A bookmark system as in claim 15, further comprising a user interface through which a user accesses said bookmark management system, said bookmark management system presents to said user over said user interface a customized view of said document according to information in said owner-specific record and in said document record.

17. A bookmark system as in claim 15, further comprising a graphical user interface, said graphical user interface displaying for each document record shared information of an owner-specific record associated with said document record.

18. A bookmark system as in claim 17, wherein said shared information comprises annotation.

19. A bookmark system as in claim 1, wherein said bookmark management system associates with each document only one document record.

20. A bookmark system as in claim 1, wherein said bookmark management system collects documents by crawling.

21. A bookmark system as in claim 20, wherein said crawling is semnantic-based.

22. A bookmark system as in claim 20, wherein said crawling is domain independent.

23. A bookmark system as in claim 20, said crawling being limited by the number of levels of links followed from said document.

24. A bookmark system as in claim 20, wherein said crawling calculates an estimated time based on said access pattern.

25. A bookmark system as in claim 20, wherein said crawling provides sample documents prior to completion of said crawling.

26. A bookmark system as in claim 20, wherein said crawling is conducted within a specified domain.

27. A bookmark system as in claim 20, said crawling being limited by the number of levels of links pointing to said document.

28. A bookmark system as in claim 20, further comprising a user interface to allow a user to specify parameters of said crawling.

29. A bookmark system as in claim 28, wherein said parameters include number of links to traverse from a seed document.

30. A bookmark system as in claim 28, wherein said parameters include number of levels of links to traverse.

31. A bookmark system as in claim 28, wherein said bookmark management system accessing and displaying a selected number of documents in said crawling prior to completion of said crawling.

32. A bookmark system as in claim 1, wherein said database management system includes a folder that relates said document and other folders by pointers.

33. A bookmark system as in claim 32 wherein said bookmark management system allows traversal of document records and said folders by pointers.

34. A bookmark system as in claim 32 wherein said bookmark management system maintains an access pattern for said document record, said bookmark management system associating said document record with said folder when said access pattern matches predetermined criteria.

35. A bookmark system as in claim 32, wherein a document record associated with said folder is marked for deletion.

36. A bookmark system as in claim 32, wherein said folder references documents records having access frequencies exceeding a predetermined value.

37. A bookmark system as in claim 32, wherein said folder record references documents to be accessed on a regular basis.

38. A bookmark system as in claim 32, wherein said folder record is associated with documents to be accessed when introduced or updated, introducing or updating of said documents being ascertained by performing incremental search.

39. A bookmark system as in claim 38, wherein said bookmark management system informs a user when a document record referenced in said folder is updated.

40. A bookmark system as in claim 1, said bookmark management system provides a page rank based on an evaluation based on one or more of the following quantities:

access frequency, popularity and number of referrals.

41. A bookmark system as in claim 1 further including a user configurable graphical user interface.

42. A bookmark system as in claim 41, wherein said user configurable graphical user interface customizing query to said database management system according to a configuration of said configurable graphical user interface.

43. A bookmark system as in claim 1, further comprising a graphical user interface, said graphical user interface displaying for each document record information of an owner-specific record associated with said document record.
