Data Cleansing Algorithm
Input: Web Server Log File data
Output: Log File data
Step 1:
Read log file record from (Web Server Log File)
Step 2:
IF ((log file record. referrer == ‘/modules/main/bottom.php’)||
(log file record. referrer ==
‘/activity/Jason’)|| (log file
record. referrer == ‘/messages/notification’)|| (log file record.
referrer == ‘/tracker/load’)|| (log file record. referrer ==
‘http://i
-
learn.uitm.edu.my/v3’))
{ Remove from the log file }
End IF
Step 3:
Repeat step 1 and st
ep 2 until EOF (End of File)
Step 4:
Stop and save file in database.
END
User Identification Algorithm
Input: Log File data
Output: Unique User Table
Step 1:
Initialization
Create Table include the following field:
(UserID, Matric No., Date access, Path, Operating system, Browser, IP
address)
Step 2:
Read record from
log file data
Step 3:
User’s matric no. sequential records are compared
Step 4:
IF (matric no. is NOT IN Users Table)
THEN assign UserID to matric no.
Add both to Users Table
ELSE IF (matric no. is IN User Table)
THEN Add it with same UserID
ELSE Assign (
next UserID) to matric no.
Add both to User Table
Step 5:
Repeat step 2 to step 5 until EOF (Log File data)
Step 6:
Stop and store result.
