Class JCoReAnnotationIndexMerger

  • public class JCoReAnnotationIndexMerger
extends Object
    This class takes multiple UIMA indices, e.g. Token, EntityMention and Part of Speech, and merges them into a single iterator that then outputs the respective annotations as a sequence. The most useful functionality is the capability of the annotation merger to sort the annotations efficiently on the fly by start offsets. Thus, when given a range of UIMA annotation indices, the annotation merger is able to intertwine the annotations in correct reading order.

        public JCoReAnnotationIndexMerger​(Set<?> annotationTypes,
                                  boolean sort,
                                  org.apache.uima.cas.text.AnnotationFS coveringAnnotation,
                                  org.apache.uima.jcas.JCas aJCas)
                           throws ClassNotFoundException
        Constructs a new annotation index merger.
        Parameters:
        annotationTypes - The CAS integer constant of the types, the qualified Java class names of the types or the Type object of the types to merge the annotation indexes.
        sort - If set to true, the annotations will be returned sorted ascendingly by begin offset.
        coveringAnnotation - May be null. If given, the returned annotations will be restricted to those covered by the given annotation.
        aJCas - The CAS containing the annotations.
        Throws:
        ClassNotFoundException
