Method Detail

• contains

  public static boolean contains(Annotation bigAnnotation,
                 Annotation smallAnnotation)

• getAnnotationsExtent

  public static int[] getAnnotationsExtent(List<? extends Annotation> annotations)

• getSurroundingText

  public static <TOKEN_TYPE extends Annotation> String getSurroundingText(JCas jCas,
                                                          Annotation annotation,
                                                          Class<TOKEN_TYPE> tokenClass,
                                                          int numberOfTokens,
                                                          boolean before)

  This method provides a way of getting some text before or after an annotation specified by some "window" of "tokens". For example, you could retrieve the text corresponding to 5 tokens to the right of a named entity. This may be useful for e.g. creating a report that shows the output of an annotator such that surrounding text is included.

  Parameters:

  annotation - an annotation to get surrounding/nearby text from. This can be any kind of annotation.

  tokenClass - the kind of "tokens" to use. This could be any kind of annotation type as well.

  numberOfTokens - the number of tokens to consider when creating a span of text

  before - determines whether to return text occuring before the annotation or after

  Returns:

  a span of text that occurs before or after the annotation which will either end at the beginning of the annotation or begin at the end of the annotation. The other edge of the span is determined by the start/end location of the "token" found on either side of the annotation. If such a "token" does not exist then the other edge of the span will be either end of the document text.

• overlaps

  public static boolean overlaps(Annotation annotation1,

                                             Annotation annotation)

• selectMatching

  public static <T extends Annotation> List<T> selectMatching(JCas jCas,
                                              Class<T> selectedType,
                                              Annotation annotation)
