Thanks Timothy for the details. I guess I was looking for sections/segment
only. I tried to work out that piece, but unable to pull information, can you
please guide me a bit.
Below is the code snippet to pull segment information.
for(IdentifiedAnnotation entity : JCasUtil.select(jcas,
IdentifiedAnnotation.class)) {
if(entity.getTypeID() != 0)
System.out.println("Entity: " + entity.getTypeID() +
" === Text: " +
entity.getCoveredText() +
" === Polarity: " +
entity.getPolarity() +
" === Subject: " +
entity.getSubject() +
" === EntityName: " + entity.getType());
}
for (Segment segment : JCasUtil.select(jcas, Segment.class)) {
List<LabMention> mentions = JCasUtil.selectCovered(jcas, LabMention.class,
segment);
System.out.println("LATEST DATA : " + segment.getPreferredText() + "
(" + segment.getId() + "): " + mentions.size() + " mention(s)");
First for loop is giving me correct result, but second for loop is giving null
error.
