Figure 15 shows the main menu of the OLAM of path traversal patterns. It consists of
three parts: initialization, switch to automatic update web log periodically and path traversal
patterns. After 'initialization' is executed, a set of potential user navigation paths and user
access statistics summary are generated for analysis.
Initialization
The initialization consists of three major components, including: Open Log File, step
1 of data loading and cleansing and step 2 of extracting and rule generation. We can simply
click the buttons sequentially and follow the instruction to complete the process.
Figure 16 shows the screen layout of access path patterns. The program will ask
users to select/specify several parameters before building the potential user access paths
and statistics summary. First, users should select the target web page and time dimension
that they are interested in. Also, the two thresholds values, Support and Confi dence, can
be set according to the user preference. Then by clicking the button, “Build Path Traversal
Patterns”, a set of potential access paths are generated. There are two windows in the screen.
Both show the same information of user navigation paths. One is in graphic form, say FP-
tree, while the other one is in text form for easy readability. As a result, analysts can obtain
their desired knowledge.
