Agenda

• Introduction of Febrl
• Background
• Overview of GUI
• Technology required
• Demonstration
• Timetable

An outline of Febrl

• Freely Extensible Biomedical Record Linkage
  Release 0.3
• The software has been developed by ANU Data
  Mining Group
• The software designed to provide three main
  functions to analysis data sets provided

4
Three Functions

• Data Cleaning and Standardization
• The aim is to transform the information stored in
  the
• original data into a well defined and
  consistent form
• Deduplication
• Removing the duplicate records
• Record Linkage
• Comparing records and deciding whether they are a
  match or a non-match, or leaving the decision to
  the user

• Patient
• Belconnen
• Record A

• Woden
• Record B

? Record Linkage Function

Overview of main steps for original Febrl

• The first one deals with data cleaning and
  standardization
• The second aims to perform actual linkage or
  deduplication
• The user needs to specify various settings in
  order to be able to perform a cleaning/
  standardization/or a linkage/deduplication

7
Overview of GUIWhy is GUI so important?

• The original Febrl can only be operated by the
  user who knows the command of the Python
  programming language
• It is hard and complicated to modify the initial
  data for the user
• The user needs to be familiar with the rules of
  parameters and the structure of original Febrl

8

• Parameter
• m_prob
• Maximum value 0.99
• If typing the value is bigger than the max
• m_prob 1
• Traceback (most recent call last)
• OverflowError math range error

9
Functions of Graphical User Interface

• The main multi-panel visualizing parameters used
  in Febrl for users
• Inside GUI, rules of setting distinctive
  parameters have been set in.
• The sequence of setting parameters matches native
  processes of origin Febrl
• The GUI provides flexible ways for user to enter
  or modify the parameters for the date set
• The output result can be visualized to be
  displayed in the sub-panel
• The background processing is relatively
  transparent for user

10
The structure of classes for GUI

• The hierarchy of class diagram generally follows
  the relationship between wx.Frame and wx.Panel

11
How to implement background processing through GUI

• All parameters setting are recorded at real time
• After initialization, the similar Python modular
  code will be generated to be executed
• The Python code has the same function as the
  original Febrl one
• Such as project-deduplicate.py

The diagram of connecting GUI to Febrl
Output results
13
Display of output results

• The structure of tree is used to exhibit the
  input and output.
• Users can choose any output showed in the tree
  of the left panel
• There are two sub-panels in right panel which
  display two different results of output

14
Technology needed

• Python Python is an object-oriented and
  scripting programming language
• wxPython wxPython is a GUI toolkit for the
  Python programming language. It allows
  programmers to create programs with a functional
  graphical user interface.
• Eclipse SDK plus Pydev it is popular
  combination tools to develop various python
  projects including python GUI project.
• MVC Model-View-Controller

15
Demonstration
16
Timetable

• Week 12 Familiar with the Febrl and preparing
  technology knowledge
• Week34 Initial presentation and Initial
  requirement report
• Week 56 Draft graphical user interface
  programming accomplished
• Week 78 Background process programming
• Week 9 10 Debugging and updating
• Week 1113 Finishing the final report
