"Web Usage Mining: Finding Exit Pages"

Are

Hi Community,

right now I make some logfile analysis and I was wondering if there is an "easy" way to get the exit pages out of the Logs.
Of course I can manually look at all sessions an tell RM to take the URI in Row Nr. X as Exit Page for session Y but having a process doing this automatically would be much more convenient. 

The goal is to create a new attribute containing the Exit Page for each session and use this afterwards for classification.

Does somebody have experience in this area and can help me out?

Best,

Edin

Hi,
this is possible if you make creative use of the operators that are available.

As a short how to I came up with that process:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.0">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>

      </operator>

            <parameter key="condition_class" value="attribute_value_filter"/>
            <parameter key="parameter_string" value="label=%{loop_value}"/>
          </operator>
          <operator activated="true" class="sort" compatibility="5.0.11" expanded="true" height="76" name="Sort" width="90" x="179" y="30">

            </list>
          </operator>
          <connect from_port="example set" to_op="Filter Examples" to_port="example set input"/>
          <connect from_op="Filter Examples" from_port="example set output" to_op="Sort" to_port="example set input"/>
          <connect from_op="Sort" from_port="example set output" to_op="Extract Macro" to_port="example set"/>

          <portSpacing port="sink_out 1" spacing="0"/>
          <portSpacing port="sink_out 2" spacing="0"/>
        </process>
      </operator>
      <operator activated="true" class="append" compatibility="5.0.11" expanded="true" height="76" name="Append" width="90" x="492" y="30"/>
      <connect from_op="Retrieve" from_port="output" to_op="Generate ID" to_port="example set input"/>
      <connect from_op="Generate ID" from_port="example set output" to_op="Loop Values" to_port="example set"/>
      <connect from_op="Loop Values" from_port="out 1" to_op="Append" to_port="example set 1"/>
      <connect from_op="Append" from_port="merged set" to_port="result 1"/>
      <portSpacing port="source_input 1" spacing="0"/>
      <portSpacing port="sink_result 1" spacing="0"/>
      <portSpacing port="sink_result 2" spacing="0"/>
    </process>
  </operator>
</process>

It will extract the attribute value a1 from the sequence defined by the label values of iris
