with IEMS

● ●

Developer : Yoon Suk Chang, 4288977 Supervisor : Dr. Eric McCreath

Issues
●

E-mail management : Everyday task with a lot of email items E-mail : Small database with sender, text, ... Sorting e-mail items : time and money Automatic Induction → Help user

User Command Predicted Folder

Folders where email items will be organised

Key Issues
● ● ● ● ●

Intelligent E-mail sorting Restructuring Thunderbird : Extension User pattern : What user will do Prediction rules in Email sorting Future Research : AI, Smart clustering

System and Interaction
Email Client

E-mail items Email Server

Predicted Email items

Users

Decision

Gathering user pattern

Target folder

User Pattern

Selected Email item

User patterns are used to know :

how a user have organised e-mail items -> how the user will organise e-mail items

Gathering user pattern (cont.)
● ● ●

email : {sender, title, date, body text, ...} folder : {name, uri, ...} set of user pattern : {(email x folder)}

Prediction (Induction)
● ●

Analysis on gathered user patterns Creating prediction Rules for e-mail sorting : Reasoning target folder of e-mail items First matching rule → Folder name Unknown if there is no match Prototype using sender name and folder uri Future research

Implementation issue
●

Complexity of Thunderbird
●

Many languages : XUL, Javascript and XPCOM Numerous global variables and global functions scattered in 764 files Thunderbird library : XPCOM components No documentation about the structure of Thunderbird, only some sample source codes

●

●

●

●

Limitation with Thunderbird : global variable gDBView returned by Thunderbird library
●

Can not modify the appearance of UI Account -> Folder -> Email items (Impossible) Email items shown by UI -> find folder using Thunderbird functions which internally use XPCOM components

●

●

Evaluation and Test
●

Evaluation for Requirement
● ● ●

Check list to take a look at each requirement item All requirement items are satisfied Some enhancement is required Event -> check functions if the System works correctly No significant errors.

●

Test

Plan / Management
● ● ● ● ● ● ● ●

Stage Documentation Req. Specification Background Research Requirement Analysis Modelling Implementation Test / Acceptance

weeks : 15 (13) : 2 : 6 (5) : 4 : 2 : 5 (4) : 2

Conclusion and Future work
● ●

Complexity of Thunderbird Flexible design and source code

The End
