Abstract

Unique content in interrelated email messages is identified and duplicate content filtered out for user friendly display of a flow of exchange within the interrelated messages. Follow-on messages such as replies or forwards are compared to the original message to determine which part of a follow-on message is not present in the original message and is a unique part of the follow-on message. The comparison includes parsing of the messages to extract user viewable parts determination of which extracted part is the last message part containing unique information. Once the unique message part is determined, message body that excludes everything after the unique part including the headers is be displayed.

Claims

1. A method to be executed at least in part in a computing device for removing duplicate content in displaying interrelated messages, the method comprising:

receiving at least two interrelated messages;

determining matching content parts within the interrelated messages;

determining unique content by comparing the matching content parts and detecting a non-matching portion in a content part;

extracting the content part containing the unique content; and

displaying the interrelated messages by including only extracted content parts with unique content.

2. The method of claim 1, further comprising removing a content part containing unique content if the content part is a header.

3. The method of claim 1, wherein the content parts are determined from the user viewable message parts.

4. The method of claim 1, wherein determining the unique content further includes ignoring formatting and style attributes of matching content parts.

5. The method of claim 1, wherein the content parts include at least one from a set of:

textual data, graphical data, an image, an audio file, a video file, and a location identifier link.

6. The method of claim 1, wherein determining the unique content further includes detecting and ignoring a message editor based conversion.

7. The method of claim 1, wherein at least one of determining matching content parts and determining unique content also includes utilizing at least one of:

a tagging scheme identifying content origin and a checksum scheme associated with each content part.

8. The method of claim 1, wherein determining the unique content further includes detecting a content part including at least one of an advertising blurb and a disclaimer.

9. The method of claim 8, further comprising removing the content part including at least one of an advertising blurb and a disclaimer from the displayed messages.

10. The method of claim 8, further comprising displaying the content part including at least one of an advertising blurb and a disclaimer only once in the displayed messages and ignoring the content part for the purpose of determining unique content in a remainder of the content parts.

11. A computing device capable of executing an email application for removing duplicate content in displaying interrelated messages, comprising:

a memory;

a data store; and

a processor coupled to the memory and the data store, wherein the processor is configured to;

receive an original message and a reply message;

determine user viewable body text from both messages;

determine matching message parts within the original message and the reply message;

determine unique text portions by comparing the matching message parts and detecting a non-matching text portions;

extract the unique text portions;

extract a message part containing a unique text portion, if the unique text portion is integrated in the message part with non-unique text portions; and

display the original message and the reply message by including the extracted unique text portions and the extracted message part only.

12. The computing device of claim 11, wherein a formatting, a font, a style, and a size of the message parts are ignored when determining the unique text portions.

13. The computing device of claim 11, wherein the processor is further configured to:

compare at least one additional message to the original message and the reply message iteratively determining matching message parts and determining unique text portions.

14. The computing device of claim 11, wherein the processor is further configured to:

remove a message part from display if the message part is determined to be a header containing information associated with at least one of a sender, a recipient, and a subject of the message.

15. The computing device of claim 11, wherein the original message and the reply message are part of a conversation.

16. A computer-readable storage medium with instructions stored thereon for removing duplicate content in displaying interrelated messages, the instructions comprising:

receiving a plurality of interrelated messages;

determining content parts within each of the plurality of interrelated messages;

determining whether each of the content parts is one of a header and a message body part;

removing determined headers in each of the messages other than a top header in each message;

determining matching message body parts within the interrelated messages;

determining if any of the matching message body parts include unique content by comparing the matching content parts and detecting a non-matching portion;

extracting the message body parts containing the unique content; and

displaying user selected interrelated messages by including only extracted message body parts with unique content.

17. The computer-readable storage medium of claim 16, wherein the instructions further comprise:

if a message body part includes unique content inserted in between duplicate content, extracting the entire message body part for subsequent display.

18. The computer-readable storage medium of claim 16, wherein the comparison of matching content parts includes parsing of textual data in the content parts and comparison at one of:

word and sentence level.

19. The computer-readable storage medium of claim 16, wherein the user selected messages are displayed according to a user interface scheme reflecting relationships between the interrelated messages.

20. The computer-readable storage medium of claim 16, wherein the content parts include at least one from a set of:

textual data, an audio recording, a video recording, an image, application data, and a graphic.
