问题
I have a dictionary created from the DictionaryCreator from UIMA, I would like to annotate a piece of text using the DictionaryAnnotator and the aforementioned dictionary, I could not figure out how to get the annotated text. Please let me know if you do. Any help is appreciated. The code, the dictionary-file and the descriptor is mentioned below, P.S. I'm new to Apache UIMA.
XMLInputSource xml_in = new XMLInputSource("DictionaryAnnotatorDescriptor.xml");
ResourceSpecifier specifier = UIMAFramework.getXMLParser().parseResourceSpecifier(xml_in);
AnalysisEngine ae = UIMAFramework.produceAnalysisEngine(specifier);
JCas jCas = ae.newJCas();
String inputText = "Mark and John went down the rabbit hole to meet a wise owl and have curry with the owl.";
jCas.setDocumentText(inputText);
printResults(jCas);
public static void printResults(JCas jcas) {
FSIndex<Annotation> index = jcas.getAnnotationIndex();
for (Iterator<Annotation> it = index.iterator(); it.hasNext(); ) {
Annotation annotation = it.next();
List<Feature> features;
features = annotation.getType().getFeatures();
List<String> fasl = new ArrayList<String>();
for (Feature feature : features) {
try {
String name = feature.getShortName();
System.out.println(feature.getName());
String value = annotation.getStringValue(feature);
fasl.add(name + "=\"" + value + "\"");
System.out.println(value);
}catch (Exception e){
continue;
}
}
}
}

Alternatively, you could also use Apache Ruta, either with the workbench (recommended to get started) or with java code.
For the latter, I created an example project at https://github.com/renaud/annotate_ruta_example. The main parts are:
a list of names in src/main/resources/ruta/resources/names.txt (a plain text file)
Mark
John
Rabbit
Owl
Curry
ATH-MX50
CC234
a Ruta script in src/main/resources/ruta/scripts/Example.ruta
PACKAGE example.annotate; // optional package def
WORDLIST MyNames = 'names.txt'; // declare dictionary location
DECLARE Name; // declare an annotation
Document{-> MARKFAST(Name, MyNames)}; // annotate document
and some java boilerplate code to launch the annotator:
JCas jCas = JCasFactory.createJCas();
// the sample text to annotate
jCas.setDocumentText("Mark wants to buy CC234.");
// configure the engine with scripts and resources
AnalysisEngine rutaEngine = AnalysisEngineFactory.createEngine(
RutaEngine.class, //
RutaEngine.PARAM_RESOURCE_PATHS,
"src/main/resources/ruta/resources",//
RutaEngine.PARAM_SCRIPT_PATHS,
"src/main/resources/ruta/scripts",
RutaEngine.PARAM_MAIN_SCRIPT, "Example");
// run the script. instead of a jCas, you could also provide a UIMA collection reader to process many documents
SimplePipeline.runPipeline(jCas, rutaEngine);
// a simple select to print the matched Names
for (Name name : JCasUtil.select(jCas, Name.class)) {
System.out.println(name.getCoveredText());
}
there is also some UIMA type (annotation) definitions, check src/main/resources/desc/type/ExampleTypes.xml, src/main/resources/META-INF/org.apache.uima.fit/types.txt and src/main/java/example/annotate.
how to test it
git clone https://github.com/renaud/annotate_ruta_example.git
cd annotate_ruta_example
mvn clean install
mvn exec:java -Dexec.mainClass="example.Annotate"
