Labels in cluster tree

anamorillo

Hello,
I'm clustring documents, to do that I use a "Process documents from files" operator (incluing tokenizers and filters), then I use the clustering operator
How could i put the label or the name of the document (introduced as class name in text directories) in the cluster tree and the folder view?
Thank you very much!

Hi anamorillo,

I just noticed this has been sitting without a reply.  It's actually really simple, just change that attribute to an ID role before your clustering. 
Have a look at this example:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="7.0.000">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="7.0.000" expanded="true" name="Process">
    <process expanded="true">
      <operator activated="true" class="retrieve" compatibility="7.0.000" expanded="true" height="68" name="Retrieve Products" width="90" x="45" y="136">
        <parameter key="repository_entry" value="//Samples/data/Products"/>
      </operator>
      <operator activated="true" class="select_attributes" compatibility="7.0.000" expanded="true" height="82" name="Select Attributes" width="90" x="112" y="34">
        <parameter key="attribute_filter_type" value="single"/>
        <parameter key="attribute" value="Product ID"/>
        <parameter key="invert_selection" value="true"/>
        <parameter key="include_special_attributes" value="true"/>
      </operator>
      <operator activated="true" class="set_role" compatibility="7.0.000" expanded="true" height="82" name="Set Role" width="90" x="313" y="187">
        <parameter key="attribute_name" value="Product Name"/>
        <parameter key="target_role" value="id"/>
        <list key="set_additional_roles"/>
      </operator>
      <operator activated="true" class="k_means" compatibility="7.0.000" expanded="true" height="82" name="Clustering" width="90" x="447" y="34">
        <parameter key="k" value="4"/>
      </operator>
      <connect from_op="Retrieve Products" from_port="output" to_op="Select Attributes" to_port="example set input"/>
      <connect from_op="Select Attributes" from_port="example set output" to_op="Set Role" to_port="example set input"/>
      <connect from_op="Set Role" from_port="example set output" to_op="Clustering" to_port="example set"/>
      <connect from_op="Clustering" from_port="cluster model" to_port="result 1"/>
      <connect from_op="Clustering" from_port="clustered set" to_port="result 2"/>
      <portSpacing port="source_input 1" spacing="0"/>
      <portSpacing port="sink_result 1" spacing="0"/>
      <portSpacing port="sink_result 2" spacing="0"/>
      <portSpacing port="sink_result 3" spacing="0"/>
    </process>
  </operator>
</process>
