Sean Finan commented on CTAKES-528:
-----------------------------------
There is currently no confidence calculated by the dictionary lookup module.
There are plans to implement this with a case-sensitive NER engine, but the
confidence will be very rough.
> 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
> Priority: Major
>
> 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?
