  Hello @Hamidah,
  
  You can use read document operator in "Text Processing" Toolbox to read pdf files. You need to install this from the marketplace in rapidminer (Extensions --> Market Place).
  
  Here is a link related to the similar discussion.

  Hi @Hamidah,
  
  Have you tried Text Processing extension from RapidMiner maketplace?
  
  
  
  Using "Read document" you can extract the text from a pdf file.
  
  

  <?xml version="1.0" encoding="UTF-8"?><process version="9.3.001">
    <context>
      <input/>
      <output/>
      <macros/>
    </context>
    <operator activated="true" class="process" compatibility="9.3.001" expanded="true" name="Process">
      <parameter key="logverbosity" value="init"/>
      <parameter key="random_seed" value="2001"/>
      <parameter key="send_mail" value="never"/>
      <parameter key="notification_email" value="yhuang@rapidminer.com"/>
      <parameter key="process_duration_for_mail" value="1"/>
      <parameter key="encoding" value="SYSTEM"/>
      <process expanded="true">
        <operator activated="true" class="open_file" compatibility="9.3.001" expanded="true" height="68" name="Open File" width="90" x="112" y="34">
          <parameter key="resource_type" value="URL"/>
          <parameter key="url" value="http://www.pdf995.com/samples/pdf.pdf"/>
        </operator>
        <operator activated="false" class="write_file" compatibility="9.3.001" expanded="true" height="68" name="Write File" width="90" x="246" y="34">
          <parameter key="resource_type" value="file"/>
          <parameter key="filename" value="C:\Users\YuanyuanHuang\Documents\Temp"/>
          <parameter key="mime_type" value="application/octet-stream"/>
        </operator>
        <operator activated="true" class="text:read_document" compatibility="8.2.000" expanded="true" height="68" name="Read Document" width="90" x="447" y="34">
          <parameter key="extract_text_only" value="true"/>
          <parameter key="use_file_extension_as_type" value="false"/>
          <parameter key="content_type" value="pdf"/>
          <parameter key="encoding" value="SYSTEM"/>
        </operator>
        <connect from_op="Open File" from_port="file" to_op="Read Document" to_port="file"/>
        <connect from_op="Read Document" from_port="output" 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>
  

  
  

  
  

  
  Cheers,
