It has bothered me because I think it should be simple  but I have not found any solution for it.
I have a document and I want to split it in its sentences. I used tokenizer component and it only gives me a colored document. I mean I want to extract its sentences and put each sentence in a example set. my process is listed at below.
thanks a lot!

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.3.008">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="5.3.008" expanded="true" name="Process">

The tokens are colored to see a preview of the tokenization. If you want to create an example set you will have to create a word list (which is in your case a sentence list) and with the "Wordlist to Data" operator you will get an example set. See process below:

Code:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.3.009">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="5.3.009" expanded="true" name="Process">
    <process expanded="true">
      <operator activated="true" class="text:create_document" compatibility="5.3.001" expanded="true" height="60" name="Create Document" width="90" x="45" y="30">
        <parameter key="text" value="He went to USA. I went to Germany."/>
      </operator>
      <operator activated="true" class="text:process_documents" compatibility="5.3.001" expanded="true" height="94" name="Process Documents" width="90" x="179" y="30">
        <process expanded="true">
          <operator activated="true" class="text:tokenize" compatibility="5.3.001" expanded="true" height="60" name="Tokenize" width="90" x="246" y="30">
            <parameter key="mode" value="linguistic sentences"/>
          </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>
      <operator activated="true" class="text:wordlist_to_data" compatibility="5.3.001" expanded="true" height="76" name="WordList to Data" width="90" x="313" y="30"/>
      <connect from_op="Create Document" from_port="output" to_op="Process Documents" to_port="documents 1"/>
      <connect from_op="Process Documents" from_port="word list" to_op="WordList to Data" to_port="word list"/>
      <connect from_op="WordList to Data" from_port="example 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>

In this case you have to:
- use an example set that contains all documents
- add an ID to the data
- split the data using Cut Document*
- activate keep_text in Process Documents
- Join the original document data to the split data

*) In Cut Document, you have to manually specify a regular expression that detects linguistic sentences. As you can see, the one I invented is not yet perfect.

Code:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
