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/>

     <portSpacing port="source_input 1" spacing="0"/>
     <portSpacing port="sink_result 1" spacing="0"/>
     <portSpacing port="sink_result 2" spacing="0"/>

    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.

    Here's a demo video: http://www.youtube.com/watch?v=3Kntxr16EwE
