Sai, here's an example from what I'm using. I'm using multiple threads to
process documents concurrently, if you're not interested in that you can
ignore the CASPool stuff and just instantiate a CAS directly. You *do*
want to re-use CAS instances though, they're very expensive to create.
// the name of the analysis engine xml file
String pipelineFileName =
./desc/ctakes-clinical-pipeline/desc/analysis_engine/AggregatePlaintextUMLSProcessor.xml;
// the number of simultaneous pipelines to support
int threadCount = 3;
// load the pipeline specifier
XMLInputSource input = new XMLInputSource(new File(pipelineFileName));
ResourceSpecifier pipelineSpecifier =
UIMAFramework.getXMLParser().parseResourceSpecifier(input);
// create the analysis engine for the pipeline and allocate some CAS
AnalysisEngine analysisEngine =
UIMAFramework.produceAnalysisEngine(pipelineSpecifier, threadCount, 0);
CasPool casPool = new CasPool(threadCount, analysisEngine);
// for each document...
CAS cas = casPool.getCas();
try
{
// process the document
cas.reset();
cas.setDocumentLanguage("en");
cas.setDocumentText(textToAnalyze);
// then consume the assertions of whatever type you're interested in
Type eventType =
cas.getTypeSystem().getType("org.apache.ctakes.typesystem.type.textsem.EventMention");
FSIterator<FeatureStructure> iter =
cas.getIndexRepository().getAllIndexedFS(eventType);
while (iter.hasNext())
{
FeatureStructure fs = iter.next();
// extract information from the assertion
}
}
finally
{
casPool.releaseCas(cas);
}
