     FIELD OF THE INVENTION 
     The invention relates to an email system that utilizes a threading service. 
     BACKGROUND OF THE INVENTION 
     Conventional document management systems incorporate an interest generation system that uses storing operations (i.e., outbound operations) to determine content (e.g., topics, names and other content) to add to a dynamic interest profile. However, in the context of messaging systems, some outgoing messages may not include all relevant information when they are merely replies to other messages. In other words, a reply to a message may not include the text or content of the original message or other messages related thereto. As a result, any dynamic interest profile built, at least in part based on outgoing messages, may not include all information that may be relevant. 
     What is needed is an improved mechanism for generating a dynamic interest profile. 
     SUMMARY OF THE INVENTION 
     The invention solving these and other problems creates an improved dynamic interest profile that is based on text or content of a set messages related to an outgoing message rather than just the outgoing message itself. 
     According to various embodiments of the invention, a profile module uses a threading service to expand topics and names used to create a dynamic interest profile. The profile module constructs the dynamic interest profile in order to sort, cluster, and otherwise call attention to messages that may be of interest to a user. In some embodiments, the profile module automatically constructs the dynamic interest profile. The dynamic interest profile may include various items of user interest including topics, names, documents, document repositories, or any other items of user interest. In some embodiments of the invention, the profile module may utilize a threading service. This threading service may reside locally at a user terminal or remotely on a server. 
     The profile module monitors outgoing messages sent by a user from an email system. In some embodiments of the invention, for each outgoing message, the profile module identifies whether the outgoing message is part of a thread or other set of related messages. If so, the profile module requests a list of messages related to the outgoing message from the threading service. The list of related messages may include the outgoing message and all messages in the same “thread,” or messages determined by the threading service to be related to the outgoing message. 
     After receiving the list of related messages, the profile module scans the outgoing message and the related messages for terms or content to add to the dynamic interest profile. In some embodiments of the invention, the profile module scans related messages that include both incoming messages and outgoing messages. In some embodiments, the profile module may include an algorithm for weighting the terms or content added to the dynamic interest profile. 
     Other objects and features of the invention will become apparent from the following detailed description considered in connection with the accompanying drawings. The drawings are designed for purposes of illustration only and the invention is not limited to the particulars shown therein. Various alternatives and modifications within the scope of the invention will be apparent from the description contained herein.

       FIG. 2  illustrates an exemplary user interface  200  for email system  120  according to various embodiments of the invention. User interface  200  may includes a toolbar  222  from which a user may manage one or more email messages in email system  120 . Toolbar  222  may include various items related to email features including any one or more of New Message  222   a , Reply  222   b , Delete  222   c , Forward  222   d , Send/Receive  222   e , Search  222   f . Toolbar  222  may include other items corresponding to other email feature as would be apparent. 
     Items included in toolbar  222  allow a user to access various aspects of the invention. For example, selecting Reply  222   b  invokes access to reply module  140 , selecting Delete  222   c  invokes access to delete module  130 , and selecting Search  222   f  invokes accesses to search module  160 . 
     Further, user interface  200  may also include a list of messages  224  for presentation and display to the user. For example, list of message  224  may include new and saved email messages for the user. In some embodiments of the invention, each message of message set  224  includes a selection box  226  as illustrated Selection box  226  allows a user to select one or more messages and subsequently direct a performance of an action on that message, such as, for example reply, forward, or delete or other action. Although messages are described as being selected via selection box  226  in user interface  200 , messages may be selected in various other ways, such as highlighting a message, clicking on a message, or any other mechanism for selecting messages as would be apparent. 
       FIG. 3  illustrates various delete options that may be incorporated into user interface  200  and provided or otherwise controlled by delete module  130  according to one or more embodiments of the invention. Delete module  130  allows a user to delete a selected message and/or related messages in a variety of ways, including “Delete Selected Message Only”  332 , “Delete All in Thread”  334 , or “Delete All in Thread Except Selected Message”  336 . Depending on which delete option is selected, delete module  130  may access threading service  110 . 
     To utilize delete module  130  of the invention, a user selects one or more messages from list of messages  224  presented in user interface  200 . As discussed above, the user may accomplish this using selection box  226  or some other selecting mechanism. In some embodiments, the selected message may be a message that the user wishes to delete. In some embodiments, the selected message may be a message that the user wishes to keep, but the user may wish to delete any or all related messages except the selected message. In some embodiments, the user may wish to delete the selected message and all related messages. 
     After selecting a message, the user may select “Delete”  222   c  from toolbar  222  of email system  120 . Selecting “Delete”  222   c  accesses or otherwise invokes delete module  130 . Subsequently, delete module  130  may request a list of messages related to the selected message from threading service  110 . The list of related messages includes the selected message and all messages in the same “thread,” or all messages determined by threading service  110  to be related to the selected message. The list of related messages may be stored in a temporary memory buffer (not shown) of email system  120  and accessed by delete module  130 . 
     In some embodiments, after delete module  130  retrieves the list of related messages, delete module  130  may display various delete commands that provide the user with various delete options. These delete options may include “Delete Selected Message Only”  332 , “Delete All in Thread”  334 , or “Delete all in Thread Except Selected Message”  336 . The user may then select one of these in accordance with the action the user wishes to take. In some embodiments of the invention, if the user wishes to delete only the selected message, the user selects “Delete Selected Message Only”  332 . In some embodiments of the invention, if the user wishes to keep the selected message, but to delete all related messages, the user selects “Delete All in Thread Except the Selected Message”  336 . In some embodiments of the invention, if the user wishes to delete the selected message and all related messages, the user selects “Delete All in Thread.” 
     After the user has selected a delete command, delete module  130  causes the appropriate messages to be deleted. If the selected delete command was “Delete All in Thread Except the Selected Message”  336 , each of the messages in the list of related message is compared with the originally selected message. Those that do not match are deleted, leaving the originally selected message. In some embodiments of the invention, delete module  130  may simply mark the messages for deletion for the benefit of another service (not otherwise illustrated) that actually deletes the messages as would be apparent. In some embodiments of the invention, actual deletion may occur at contemporaneously, at a time specified by email system  120 , at a time specified by the user, or at a time determined by the deletion service. 
     If the selected delete command was “Delete All in Thread”  334 , each of the messages in the list of related messages, including the selected message is be deleted. As discussed above, delete module  130  may simply mark the messages for deletion for the benefit of another service. 
     If the selected delete command was “Delete Selected Message Only”  332 , the originally selected message is deleted. Again, as discussed above, delete module  130  may simply mark the selected message for deletion. 
       FIG. 4  illustrates reply options that may be incorporated into user interface  200  and provided or otherwise controlled by reply module  140  according to one or more embodiments of the invention. Reply module  140  allows a user to reply to a selected message in a variety of ways, including “Reply to Sender Only”  442 , “Reply to All Recipients”  444 , or “Reply to All in Thread”  446 . Depending on which reply option is selected, reply module  140  may access threading service  110 . 
     To utilize reply module  140  of the invention, a user selects one or more messages from list of messages  224  presented in user interface  200 . As discussed above, the user may accomplish this using selection box  226  or some other selecting mechanism. In some embodiments of the invention, the use may wish to reply to only the sender of the selected message. In some embodiments of the invention, the user may wish to reply to all the recipients of the selected message. In some embodiments of the invention, the user may wish to reply to all the recipients who received the selected message or any message related to the selected message. 
     After selecting a message, the user may select “Reply”  222   b  from toolbar  222  of email system  120 . Selecting “Reply”  222   b  accesses or otherwise invokes reply module  140 . Subsequently, reply module  140  may display various reply commands that provide the user with various reply options. These reply options may include “Reply to Sender Only”  442 , “Reply to All Recipients”  444 , or “Reply to All in Thread”  446 . The user may then select one of these in accordance with the action the user wishes to take. In some embodiments of the invention, if the user wishes to send a reply only to the sender of the selected message, the user selects “Reply to Sender Only”  442 . In some embodiments of the invention, if the user wishes to send a reply to all recipients of the selected message, the user selects “Reply to All Recipients”  444 . In some embodiments of the invention, if the user wishes to send a reply to all the recipients of the selected message or any message related to the selected message, the user selects “Reply to All in Thread”  446 . 
     After the user has selected a reply command, reply module  140  causes the appropriate reply message to be generated. If the selected reply command was “Reply to Sender Only”  442 , reply module  140  simply inserts an address of the sender of the selected message into a reply message. In some embodiments of the invention, reply module  140  retrieves an email address from the “From” field of the selected message and inserts it into the “To” field of the reply message as would be apparent. 
     If the selected reply command was “Reply to All Recipients”  444 , reply module  140  inserts an address of the sender and all recipients of the selected message into a reply message. In some embodiments of the invention, reply module  140  retrieves email addresses from the “From,” “To,” “CC,” and/or “BCC” fields of the selected message and inserts them into a corresponding field in the reply message as would be apparent. 
     If the selected reply command was “Reply to All in Thread”  446 , reply module  140  inserts an address of the sender, all recipients of the selected message, and all recipients of messages related to the selected message into a reply message. In some embodiments of the invention, reply module retrieves email addresses from a list of messages related to the selected message. In some embodiments of the invention, this may be accomplished using header information associated with each of the messages in the list of related messages to collect unique names or addresses from the address fields therein. These names or addresses may then be inserted into corresponding fields in the reply message. 
     In some embodiments of the invention, in order to “Reply to All in Thread,” reply module  140  may request a list of messages related to the selected message from threading service  110 . The list of related messages includes the selected message and all messages in the same “thread,” or those messages determined by threading service  110  to be related to the selected message. The list of related messages may be stored in a temporary memory buffer (not otherwise illustrated) of email system  120 . Reply module  140  may access the temporary memory buffer and retrieve the list of related messages. 
     In some embodiments of the invention, reply module  140  may gather header information for each message in the list of related messages. The header information gathered by reply module  140  may include a variety of data fields that are used for addressing, including, but not limited to: “From,” “To,” “CC,” “BCC,” “Sent on behalf of,” “Reply to,” or any other address data field. 
     In some embodiments of the invention, reply module  140  may collect the names or addresses from the address fields of the header data from each related message, and adds only those unique names or addresses to a stored list. The stored list of gathered header information may be stored in the temporary memory buffer (not otherwise illustrated). In some embodiments of the invention, the stored list may include information regarding the field from which the names or addresses originated. For example, “Joe Smith” may have been in the “From” field in one message and in the “To” field of a second message. 
     After the stored list of names or addresses has been compiled, reply module  140  may create a reply message that is related to the originally selected message. In some embodiments of the invention, reply module  140  may insert the names or addresses from the stored list of names or addresses into fields of the reply message corresponding to the fields from which the names or addresses originated (i.e., originating fields). In some embodiments of the invention, the corresponding field is determined by a rule set that specifies which originating fields cause names to be inserted into which address fields of the reply message with priority information should the name or address originate in more than one type of field. 
     In some embodiments of the invention, the user may also insert additional names or addresses into the address fields of the reply message as would be apparent. 
       FIG. 5  illustrates various search options that may be incorporated into user interface  200  and provided or otherwise controlled by search module  160  according to one or more embodiments of the invention. Search module  160  allows a user to search a list of messages  224  and/or related message in a variety of ways, including “Search Only for Messages that Include Search Terms”  566  or “Search for Messages that Include Search Terms and All Related Messages”  568 . Depending on which search option is selected, search module  160  may access threading service  110 . 
     To utilize search module  160  of the invention, a user selects menu item “Search”  222   f  from toolbar  222  of email system  120 . Selecting menu item “Search”  222   f  accesses or otherwise invokes search module  160 . Subsequently, search module  160  may display a query box  562  in which a user may enter one or more search terms  564 . The user may then enter search terms  564  comprising of a variety of text that is to be sought in list of message  224  as would be apparent. 
     After the user enters search terms  564  into query box  562 , the user may select from one or more search options provided by search module  160 . These search options may include “Search Only for Messages that Include Search Terms”  566  or “Search for Messages that Include Search Terms and All Related Messages”  568 . The user may select one of these in accordance with the action the user wishes to take. In some embodiments of the invention, if the user wishes to retrieve only those messages that include search terms  564 , the user may select “Search Only for Messages that Include Search Terms”  566 . In some embodiments of the invention, if the user wishes to retrieve those messages that include search terms  564  and all messages that are related thereto, the user may select “Search for Messages Containing Search Terms and All Related Messages”  568 . 
     After the user has selected a search command, search module  160  causes the appropriate search results to be generated. If the selected search command is “Search Only for Messages that Include Search Terms”  566 , search module  160  searches message set  224  for messages that include search terms  564  as would be apparent and provides those message as search results. 
     If the selected search command is “Search for Messages that Include Search Terms and All Related Messages”  568 , search module  160  searches message set  224  for messages including search terms  564 . Then, for each message that includes search terms  564 , search module  160  also determines and/or retrieves messages related thereto, whether or not the related messages include search terms  564 . Search module  160  searches each message of message set  224  for entered search terms  564 . In some embodiments of the invention, if the search terms are found including a particular message, search module  160  determines whether the particular message belongs to a thread. If so, search module  160  requests a list of messages related to the particular message from, for example, threading service  110 . This list of related messages may include the matching message and all messages in the same “thread,” or those messages determined by threading service  110  to be related to the particular message. The list of related messages may be stored in a memory buffer (not shown) of email system  120 . Search module  160  may access and retrieve the list of related messages from the particular memory buffer. Search module  160  provides search results that include the message that included the search terms  564  and the list of messages related thereto. 
     In some embodiments of the invention, after the search results are complied, search module  160  may display the search results in various ways. Search module  160  may display the search results in order of relevance, date or any other mechanism. In some embodiments, the search results may include an indication so that the user may recognize that a particular message includes search terms  564 , while another message is related to a message that includes search terms. 
     In some embodiments of the invention, the search results may be displayed such that only a set of related messages or thread of a message, where at least one message there includes the search terms  564 . In some embodiments of the invention, the user may expand/collapse the initial message to view the entire list of related messages. 
     In some embodiments of the invention, the search results that are displayed may include these messages that include search terms  564 . The displayed results may include an indication of whether the message is related to other messages. In some embodiments, the user may expand/collapse the message to view the list of related messages. 
       FIG. 6  illustrates profile module  150  according to the various embodiments of the invention. In some embodiments, profile module  150  may use threading service  110  to expand topics and names used to create a dynamic interest profile  652 . Dynamic interest profile  652  may be generated and updated on the email system  120  of user terminal  102 . 
     In some embodiments of the invention, profile module  150  automatically constructs dynamic interest profile  652  in order to sort, cluster, and otherwise call attention to messages that may be of interest to a user. Dynamic interest profile  652  may include items  654  of user interest including topics  654   a , names  654   b , documents,  654   c , document repositories  654   d , or other items of user interest. 
     In some embodiments of the invention, profile module  150  may monitor all outgoing messages that a user sends from email system  120 . Outgoing messages and messages related thereto may be used to construct items  654  of dynamic interest profile  652 , as described further below. 
     For each outgoing message, profile module  150  identifies whether the outgoing message related to other messages, by, for example, being related to a thread. If so, profile module  150  requests a list of messages related to the outgoing message from threading service  110 . The list of related messages includes the outgoing message and all messages in the same “thread,” or all those messages determined by threading service  110  to be related to the outgoing message. The list of related messages may be stored in a memory buffer (not shown) of email system  120 . Profile module  150  may access and retrieve messages from the memory buffer. 
     Profile module  150  scans the outgoing message and its related messages for terms to add to dynamic interest profile  652 . The related messages may be incoming or outgoing messages. In some embodiments of the invention, the profile module  150  may include an algorithm for weighting the terms added to dynamic interest profile  652 , such that, for example, the most relevant or frequently occurring terms appear first in dynamic interest profile  652 . In some embodiments of the invention, incoming and outgoing messages may be weighted differently according to the algorithm.
