1. Navigate to the source downloads for a released version on SourceForge

2. Download the cTAKES-2.6.zip file.
Save the file to a temporary location on your machine.

3.
Unzip (extract the contents of) the compressed file you downloaded into
a directory that you want to be the cTAKES install location.
For example, Windows:

c:\cTAKES-2.6

Linux:

/usr/bin/cTAKES-2.6

This folder we will call <cTAKES_HOME>. You will need to refer to the directory later. Image Removed

1. Open a command prompt and change to the cTAKES_HOME directory.
Windows:

cd \cTAKES-2.6

Linux:

cd /usr/bin/cTAKES-2.6

2. Start the CAS Visual Debugger by running this command:
Windows:

runctakesCVD.bat

Linux:

runctakesCVD.sh

The application may take a minute to start on slower hardware.

3. An analysis engine (AE) needs to be loaded in order to process text.
Use the Run-> *Load AE*menu bar command. Navigate to the file

<cTAKES_HOME>/cTAKESdesc/cdpdesc/analysis_engine/AggregatePlaintextProcessor.xml

Click Open.

4. Copy the text in the example at the right (next cell) and paste the
contents into the Text section of CVD, replacing the text that is
already there.
This example file can also be found in test data:

<cTAKES_HOME>/testdata/cdptest/testinput/plaintext/testpatient_plaintext_1.txt

3. From the menu bar, click Run -> Run AggregatePlaintextProcessor.
You'll get a list of all the annotations in the Analysis Results frame.

4. Named entities are now recognized in this clinical document.
Annotations of MedicationEventMention and EntityMention are created. To
find one, in the Analysis Results frame, click on the key in front of:
AnnotationIndex
uima.tcas.Annotation
edu.mayo.bmi.uima.core.type.textsem.IdentifiedAnnotation
edu.mayo.bmi.uima.core.type.textsem.EntityMention
and
edu.mayo.bmi.uima.core.type.textsem.EventMention
edu.mayo.bmi.uima.core.type.textsem.EventMention.MedicationEventMention

Then select edu.mayo.bmi.uima.core.type.textsem.EntityMention or
edu.mayo.bmi.uima.core.type.textsem.EventMention.MedicationEventMention.
This will show an Annotation Index in the lower frame. Select any
annotation in that lower frame and you will see the text discovered in
the Text frame on the right. You may close CVD if you wish.

1. Open a command prompt and change to the cTAKES_HOME directory:
Windows:

cd C:\cTAKES2.6

Linux:

cd /usr/bin/cTAKES2.6

2. Start the collection processing engine by running this command:
Windows:

runctakesCPE.bat

Linux:

runctakesCPE.sh

The application may take a minute to start on slower hardware.

3. This will bring up the Collection Processing Engine Configurator. In the Menu bar click File >Open CPE Descriptor

Image Modified

4. Navigate to the file

<cTAKES_HOME>/cTAKESdesc/cdpdesc/collection_processing_engine/test_plaintext.xml

Click Open.

5. Click the Play button (green/blue play arrow near the bottom).

6. You should see that one document was processed. You did process a collection of documents. In this case the collection only contained one just to show how to do it. Close the results window.

7. Close the CPE application. You may be prompted to save changes. Since this was just a test you may click the No button.

8. Open a new command prompt and change to the <cTAKES_HOME>

9. To test the results there is a comparison tool that will help show that the results match expectations with the following syntax:

java -cp cTAKES.jar edu.mayo.bmi.utils.xcas_comparison.Compare
<First File> <Second File> <diff-html>

Where: <First File> is the first file to compare; <Second File> is the second file to compare; <diff-html> is where the results are written to
Copy and paste the example at the right (next cell) which has had our
example files already substituted into a command prompt to run. In this
case we have shipped an example of what the output should be for you to
compare against.

Windows:

java -cp cTAKES.jar edu.mayo.bmi.utils.xcas_comparison.Compare ^
"testdata\cdptest\testoutput\plaintext\sample_note_plaintext.xml" ^
"testdata\cdptest\testsampleoutput\plaintext\sample_note_plaintext.xml" ^
c:\stuff\diff-html.html

Linux:

java edu.mayo.bmi.utils.xcas_comparison.Compare \
"/usr/bin/cTAKES2.6/testdata/cdptest/testoutput/plaintext\sample_note_plaintext.xml" \
"/usr/bin/cTAKES2.6/testdata/cdptest/testsampleoutput/plaintext/sample_note_plaintext.xml" \
/tmp/diff-html.html

10. The resulting file will open for you. Look at the comparison to see the annotations resulting from this pipeline.
Windows:

c:\stuff\diff-html.html

Linux:
