Creating a custom pipeline in cTAKES can be a daunting task.  One of the most challenging elements is simply knowing what Pipe Bits and pieces are available to create a pipeline, as well as what data types those Pipe Bits depend upon and produce.  The Simple Pipeline Fabricator GUI can help provide this information.

The Simple Pipeline Fabricator can save your pipeline in a reusable Piper File, as well as load and run Piper Files.  It only assists creating cTAKES pipelines, displaying information and allowing selection of available Readers, Annotators and Writers (Pipe Bits).  It also displays information and facilitates assigning values to Pipe Bit parameters.  However, creating a proper working pipeline requires knowledge of basic NLP artifacts and dataflow. 

Step-by-step guide

  1. From a command-line in the cTAKES root directory, execute: bin/runPiperCreator

  2. Click Scan to allow the tool to discover all pipeline components (Pipe Bits) available to cTAKES.  The scan may take several seconds.
  3. Select a Pipe Bit on the left.  Information on the Pipe Bit will be displayed in the center pane.
  4. Select a Parameter Name in the center table.  Information on the Parameter will be displayed below the table.
  5. Enter a Value in the table for any parameter that requires one.   An 'open file' button makes file selection easy.
  6. Click Add(plus) when all parameter requirements are met.  The Pipe Bit will be added to the piper file on the right.
  7. Continue to add Pipe Bits in order to create your pipeline.
