Patent Abstract:
A method for providing personalized, shared bookmarks that determines which bookmarks are to be shared with a given user based at least in part on an interest profile associated with that user. The interest file can be used to define important other users, based on attributes, titles, or names associated with those other users. Shareable bookmarks defined by important other users are provided to the local user through the local navigation program. The list of important persons used to define which bookmarks should be shared may be determined in various specific ways. An interest profile may be automatically maintained containing a list of persons that are important for a specific user. The list may be automatically calculated based on information such as recent email traffic, and/or can be defined manually. Privacy issues may be addressed by enabling a user to prevent certain bookmarks they define locally from being shared.

Full Description:
FIELD OF THE INVENTION 
   The present invention relates generally to computer application program interfaces, and more specifically to a system and method for providing shared bookmarks based on user interest profiles. 
   BACKGROUND OF THE INVENTION 
   In many contemporary computer application programs, users are allowed to maintain a set of names and/or pointers associated with documents, databases, and various other types of program or data objects that they desire to have quick access to. These conveniently accessible links, sometimes referred to as “bookmarks”, provide convenient access to any arbitrary document or location that can be referred to using a Uniform Resource Locator (URL). For example, using Netscape® Navigator and Mozilla Firefox Web browsers, a bookmark is a link to a Web page that has been added to a folder or list of saved links. When a user is looking at a particular Web site or home page, and wants to be able to quickly get back to it later, they can create a bookmark for it, and store the bookmark in a software construct referred to as a “bookmark list” or “hotlist.” The Microsoft® Internet Explorer browser, and others, also use the same idea, using different names to refer to the stored links. The Internet Explorer browser uses the term “favorite” to refer to this concept. In the present disclosure, the term “bookmark” is intended to refer to any link stored for quick access that includes or refers to a URL, and that may be directly selected by a user through a user interface, for example by a mouse click, in order to access an associated content location or document. 
   Existing systems allow for storage of bookmarks that are maintained privately, on a user by user basis. In order for a user to share their personal bookmarks with other users, they must typically send the links via electronic mail (“email”), and the receiving users must then manually add the links to their bookmark lists. 
   Some potential approaches to sharing bookmarks are to associate access control lists (ACLs) with bookmarks, or to simply make all bookmarks publicly available. A significant problem with such approaches is that they are not personalized. Accordingly, if a user shares one or more bookmarks, all other users see all the shared bookmarks. This may result in a flood of bookmarks in the user&#39;s bookmark list, and makes sharing bookmarks virtually useless. Other systems have provided replication of a user&#39;s personal bookmarks between a server and different clients, for example to support a roaming user, but they do not support sharing of bookmarks. 
   For the reasons stated above, it would be desirable to have a new system for sharing bookmarks that does not result in flooding of personal bookmark lists with shared bookmarks. 
   SUMMARY OF THE INVENTION 
   To address the above described an other shortcomings of the prior art, a system and method are disclosed for providing personalized, shared bookmarks. The disclosed system determines which bookmarks are to be shared with a given user based on an interest profile associated with that user. The interest profile can be used to define important other users, for example based on attributes, titles, or names associated with those other users. Shareable bookmarks defined by such important other users are then provided to the local user through the local navigation program. For example, bookmarks of a technical leader associated with a specific project, or of other team members for that project, or of people with similar roles to the user but belonging to other teams may be considered important for the user. This reflects the likelihood that the more important certain people are to a user, the more likely it is that their bookmarks are also important for that user. 
   The list of important persons used to define which bookmarks should be shared may be determined in various specific ways. For example, an interest profile may be automatically maintained containing a list of persons that are important for a specific user. The list may be automatically calculated based on information such as recent email traffic, and/or can be defined manually. 
   The disclosed system may be embodied to address privacy issues by enabling a user to prevent certain bookmarks they define locally from being shared. Accordingly, a user can mark bookmarks as being public or private. If a given bookmark is marked as public, then it is allowed to be automatically replicated into other users bookmark lists based on user interest profile data. 
   In this way there is disclosed a new system for sharing bookmarks that does not result in flooding of bookmark lists with shared bookmarks.

     In order to facilitate a fuller understanding of the present invention, reference is now made to the appended drawings. These drawings should not be construed as limiting the present invention, but are intended to be exemplary only. 
       FIG. 1  shows software components in an illustrative embodiment; and 
       FIG. 2  shows steps performed in the illustrative embodiment. 
   

   DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS 
   As shown in  FIG. 1 , an illustrative embodiment of the disclosed system operates using a number of software components executing on at least one client computer system, shown for purposes of illustration as the client system  10 , and at least one server computer system, shown for purposes of illustration as server system  30 . The client system  10  and server system  30  may, for example, each include at least one processor, program storage, such as memory, for storing program code executable on the processor, and one or more input/output devices and/or interfaces, such as data communication and/or peripheral devices and/or interfaces. The client system  10  and server system  30  are communicably connected by a data communication system, such as a Local Area Network (LAN), the Internet, or the like. The client system  10  and server system  30  may further include appropriate operating system software. 
   The client system is shown including a navigation application program  12 , which enables a user of the client system to define and access a number of locally defined bookmarks  14 . The navigation application program  12  further provides access to a number of shared bookmarks  15 . The navigation application  12  may consist of any specific type of application program that a local user of the client system  10  can use to navigate between different resources, such as data files, electronic documents, Web pages, databases, programs, services, or the like. An example of the navigation application  12  is a Web browser program. The bookmarks  14  and  15  consist of quickly accessible links to resources. The resources pointed to by the bookmarks  14  and  15  may conveniently be accessed by a user through a user interface provided by the navigation application  12 , for example using one more mouse clicks. In one embodiment, the bookmarks  14  and  15  each include a Uniform Resource Locator (URL). 
   A communication application  16  is monitored by an interest profile generator component  18  to generate the interest profile  20 . The communication application  16  may consist of any specific type of communication program, such as an electronic mail (“email”) application program, instant messaging (“IM”) program, or the like. The interest profile generator  18  operates to determine one or more important persons for the interest profile  20  based on which other users a local user of the client system  10  has been communicating with through the communication application  16 . For example, the interest profile generator  18  may operate to determine those other users to which messages are sent, and/or from which messages are received using the communication application  16 . Such other users to be considered as important users for the local user may be indicated within the “TO:” or “FROM:” fields of email messages sent and received by the communication application  16 . When determining a set of important persons to be indicated within an interest profile for a local user, the interest profile generator  18  may use statistical information such as how frequently a given other user communicates with the local user via the communication application  16 , how recently a given other user has been in communication with the local user via the communication application  16 , or other attributes of communications performed using the communication application  16 . Alternatively, or in addition, the interest profile generator  18  may obtain indications of important persons to be indicated by the interest profile  20  as configuration information, for example as obtained from the local user through the navigation application  12  or communication application  16 , or from a system administrator. 
   A bookmark sharing component  22  obtains indications of the important persons for the local user from the interest profile  20 , and operates to obtain and store the shared bookmarks  15  such that they are available to the navigation application  12 . The shared bookmarks  15  are bookmarks that have been defined by other users that match the important persons indicated in the interest profile  20 . The bookmark sharing component  22  obtains the shared bookmarks  15  from the server system  30 . 
   The server system  30  includes a bookmark collecting component  32  that stores a database of bookmarks, shown as the collected bookmarks  34 . The collected bookmarks  34  are obtained by the server system  30  from multiple client systems, including the client system  10 . The collected bookmarks  34  include bookmarks associated with users of those multiple client systems, other than the local user associated with the interest profile  20 . The collected bookmarks  34  are shown, for purposes of illustration, as including user  1  bookmarks  34   a , user  2  bookmarks  34   b , user  3  bookmarks  34   c , etc. The bookmarks in the collected bookmarks  34  may, for example, be collected for multiple users and/or multiple client systems associated with the server system. Collection of the bookmarks at the server system  30  may be accomplished by navigation applications on client systems transmitting their bookmarks to the server system, either periodically, and/or in response to a request or read operation from a scheduled agent executing on the server system  30 . In this way, bookmarks are up-loaded from a number of client systems, and maintained in a bookmark database on the server system  30  in association with the users that defined them. After an initial set of bookmarks for a given user is loaded into the collected bookmarks  34 , only changes to that initial set need to be communicated to and/or stored in the collected bookmarks  34 . In the illustrative embodiment, the bookmarks for a given user that are loaded into the collected bookmarks  34  include those bookmarks that are created or defined by that user, shown for example as the locally defined bookmarks  14 . Moreover, the bookmarks associated with a given user in the collected bookmarks  34  may be created or defined by that user on various specific client systems, collected centrally from those multiple client systems into the server system  30 , and associated with that user in the collected bookmarks  34 . 
   The bookmark sharing component  22  operates to generate the shared bookmarks  15  by comparing the important persons indicated in the interest profile  20  of the local user of the client system  10  with the other users (user  1 , user  2 , user  3 , etc) associated with the collected bookmarks  34  in the server system  30 . If an important person indicated by the interest profile  20  has one or more bookmarks stored in the collected bookmarks  34 , those associated bookmarks are downloaded by the bookmark sharing component  22 , and stored within the shared bookmarks  15 . Those skilled in the art will recognize that the bookmarks  14  and  15  may be organized in categories, as in a tree structure, folders, or any other appropriate organizing structure, in order to provide a convenient presentation to the local user that makes the shared bookmarks  15  conveniently identifiable as shared bookmarks. 
   While the bookmark sharing component  22 , interest profile generator  18 , and interest profile  20  are shown, for purposes of illustration, located within the client system  10  in  FIG. 1 , the present invention is not limited to such an embodiment. Accordingly, these components may alternatively, and/or additionally, be located in whole or in part within the server system  30 . For example, in order to support user sessions established by a given user on different client systems, the interest profile  20 , bookmarks  14 , and shared bookmarks  15 , may be stored on the server system  30 , for downloading or replicating to, and/or use in conjunction with, one or more client systems on which an associated user logs in or establishes a user session with the server system  30 . In such an embodiment, the identification of shared bookmarks for a given user may be performed by one or more software components executing on the server system  30 . 
     FIG. 2  is a flow chart illustrating steps performed by an illustrative embodiment of the disclosed system. As shown in  FIG. 2 , at step  40  the disclosed system generates an interest profile for a local user of a client system. The interest profile generated at step  40  includes indications of one or more important persons. Such indications may, for example, consist of user names or other identifiers corresponding to the important persons. The important persons indicated by the interest profile may be determined based on how frequently and/or how recently other users have been in communication with the local user, for example through one or more communication applications used by the local user. The important person indications may alternatively or additionally be based on configuration information received from the local user or a system manager. 
   At step  42 , bookmarks for multiple users are collected at a server system. The collection of bookmarks at step  42  may be accomplished using a scheduled agent running on the server system that checks for updates to the bookmarks of the multiple users. Each collected bookmark is stored in a database on the server system in association with the user that defined it. Accordingly, all bookmarks defined by a given user can conveniently be obtained from the database on the server system. 
   At step  44 , the local user&#39;s interest profile is used to determine which of the collected bookmarks are to be shared with the local user. To this end, the important persons in the interest profile are compared with the names of users for whom bookmarks are stored in the bookmark database. Those bookmarks associated with other users matching the important persons from the interest profile are copied to the client system currently being used by the local user. The shared bookmarks are made available to the local user at step  46 , when the disclosed system operates to store them as shared bookmarks, for example within the local user&#39;s bookmark list. The shared bookmarks within the bookmark list may then be made available to the local user through a navigation program such as a Web browser.
