Hi Pei, I though this may be have some use … Because I need to know if two or more words tokens belong to the same sentence; and since WordToken does not define the feature sentence number. I added it to the TypeSystem. These are the steps: 1) I added the sentence number features for the type BaseToken in TypeSystem.xml file (I choose the supper class in order that the feature be propagated to all subclasses (wordToken,SymboleToken,NumToken …) 2) In ctakes-core I in TokenizerAnnotatorPTB.java (methode annotateRange) I set the new feature (BaseToken.sentenceNumber = sentence.getSentenceNumber()) as shown below : bta.setSentenceNumber(sentence.getSentenceNumber()); bta.addToIndexes(); 3) Generate the JCASGen in the tab de TypeSystem of the aggregate 4) Add the feature in the source tab of the aggregate Probably I could have used as alternative: List<Sentence> list = JCasUtil.selectCovering(aJcas, Sentence.class, entity1.getBegin(), entity1.getEnd()); the issue with this is : if I have many entities to be checked at the same time or if the entity1 is found in many places, I have to add some if conditions to get sentence number
Thanks Samir
