Hi Torsten, I got the idea. The easiest way would be to use org.uimafit.component.xwriter.XWriter as a kind of visualizer. But that does not work. XWriter does always write the whole CAS instead of the mapped view. I tried
CollectionReaderDescription reader = CollectionReaderFactory... AggregateBuilder builder = new AggregateBuilder(); AnalysisEngineDescription writer = AnalysisEngineFactory.createPrimitiveDescription(XWriter.class, XWriter.PARAM_OUTPUT_DIRECTORY_NAME, outputDirectoryName); builder.add(writer, CAS.NAME_DEFAULT_SOFA, "viewName"); // viewName is the name of the view that should be serialized SimplePipeline.runPipeline(reader, builder.createAggregateDescription()); Regards, Armin -----Ursprüngliche Nachricht----- Von: Torsten Zesch [mailto:[email protected]] Gesendet: Donnerstag, 22.

If you just want to look at the annotations you might use the CAS Visualizer or CAS Editor. Or you can always write your own annotator that outputs the desired visualization. 2) As a view is just a "CAS in disguise" you may simply write a view-unaware annotator doing all the visualization on a single CAS and then use SofA mapping when assembling the pipeline. An example using uimaFIT: AnalysisEngineDescription visualizer = createPrimitiveDescription( Visualizer.class ); AggregateBuilder builder = new AggregateBuilder(); builder.add(visualizer, "_InitialView", VIEW_1); builder.add(visualizer, "_InitialView", VIEW_2); ... builder.add(visualizer, "_InitialView", VIEW_N); AnalysisEngineDescription aggr = builder.createAggregateDescription(); where VIEW_1 ... VIEW_N are the names of your views. -Torsten > -----Original Message----- > From: [email protected] [mailto:[email protected]] > Sent: Thursday, December 22, 2011 8:30 AM > To: [email protected] > Subject: Extracting a single view from a CAS > > Hi, > > how to extract a single view from a CAS with text sofas?
