Gate - extracting individual annotated text from annotation set

Question

I'm trying to extract the individual text values of an annotation set which are generated by the default ANNIE processing resources.

When i iterate through the annotation set each entry only gives the start and end position which the annotation references but does not give a .value() method. Is there an easy way to get the value or do i need to use a FileWriter or some equivalent to extract the value directly from the Corpus I'm processing using the start and end positions of the annotation?

annotTypesRequired.add("Location");

Set<Annotation> organization = new HashSet<Annotation>(
                defaultAnnotSet.get(annotTypesRequired));

Answer 1

If by "the value" you mean the text that the annotation covers, you can access that using

gate.Utils.stringFor(document, annotation)

For this you obviously need a reference to the gate.Document that the annotation belongs to, as well as the Annotation object itself - annotations do not routinely store their covered string directly, they just store offsets that point into the document's content.
