[jira] [Created] (CTAKES-528) annotation confidence is always 0

ouyeyu created CTAKES-528:
-----------------------------

             Summary: annotation confidence is always 0
                 Key: CTAKES-528
                 URL: https://issues.apache.org/jira/browse/CTAKES-528
             Project: cTAKES
          Issue Type: Wish
          Components: ctakes-type-system
    Affects Versions: 4.0.0
            Reporter: ouyeyu


I noticed that annotation.getConfidence() and umlsConcept.getScore() both always return 0.
To figure out why this happens, 
First, I found in ctakes/ctakes-dictionary-lookup/src/main/java/org/apache/ctakes/dictionary/lookup/ae/NamedEntityLookupConsumerImpl.java, the consumeHits function creates
IdentifiedAnnotation neAnnot = new IdentifiedAnnotation(jcas);
No confidence and score are added into neAnnot. 
 
Then I go to 
apache-ctakes-4.0.0-src/ctakes-type-system/target/generated-sources/jcasgen/org/apache/ctakes/typesystem/type/textsem/IdentifiedAnnotation.java
  public float getConfidence() {
    if (IdentifiedAnnotation_Type.featOkTst && ((IdentifiedAnnotation_Type)jcasType).casFeat_confidence == null)
      jcasType.jcas.throwFeatMissing("confidence", "org.apache.ctakes.typesystem.type.textsem.IdentifiedAnnotation");
    return jcasType.ll_cas.ll_getFloatValue(addr, ((IdentifiedAnnotation_Type)jcasType).casFeatCode_confidence);}
 
I further goes to the UIMA repo. 
/uimaj/uimaj-core/src/main/java/org/apache/uima/cas/impl/CASImpl.java
/uimaj/trunk/uimaj-core/src/main/java/org/apache/uima/cas/impl/CASImpl.java
  @Override
public final float ll_getFloatValue(int fsRef, int featureCode) {
    return int2float(ll_getIntValue(fsRef, featureCode));
  }
 
  @Override
public final int ll_getIntValue(int fsRef, int featureCode) {
    return this.getHeap().heap[(fsRef + this.svd.casMetadata.featureOffset[featureCode])];
  }
 
Does this mean in the heap, confidence and score are hardcoded as 0? And how is the heap created?
Is this always returning 0 a feature or a bug?
