[SOLVED] Help Needed in tokenization

gunjanamit

Hi,

I have an excel which has some comments written in each cell on A column.
I want to extract all the words and find word frequency.

My XML is


<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.2.001">
 <context>
   <input/>
   <output/>
   <macros/>
 </context>
 <operator activated="true" class="process" compatibility="5.2.001" expanded="true" name="Process">
   <process expanded="true" height="251" width="413">

       <list key="annotations">
         <parameter key="0" value="Name"/>
       </list>
       <list key="data_set_meta_data_information"/>
     </operator>
     <operator activated="true" class="text:process_document_from_data" compatibility="5.2.002" expanded="true" height="76" name="Process Documents from Data" width="90" x="246" y="120">

         </operator>
         <connect from_port="document" to_op="Tokenize" to_port="document"/>
         <connect from_op="Tokenize" from_port="document" to_port="document 1"/>
         <portSpacing port="source_document" spacing="0"/>
         <portSpacing port="sink_document 1" spacing="0"/>
         <portSpacing port="sink_document 2" spacing="0"/>
       </process>
     </operator>
     <connect from_op="Read Excel" from_port="output" to_op="Process Documents from Data" to_port="example set"/>
     <connect from_op="Process Documents from Data" from_port="example set" to_port="result 1"/>
     <connect from_op="Process Documents from Data" from_port="word list" 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>


But its not working. Can someone help please?

Under "Problems" Rapid Miner tells you that "he example set must contain at least one text attribute."
So ...

• adding a "Nominal to Text" operator between "Read Excel" and "Process Docs from Data"
  and selecting the corresponding column OR
• directly declaring your desired column as type=text instead
  of type=polynominal within the import process
  

... might work.
