  • Returns: A function that can create the java / type system class that represents the group.

static public SemanticGroup getGroup( final int code )

  • Parameters:
    • code internal cTAKES CONST code for a group. These were old constants that shouldn't be used.

    • name -short- name for a group.
  • Returns: the group with the given -short- name.

  • Returns: the group with the given -short- name.

static public Collection<SemanticGroup> getGroups( final IdentifiedAnnotation annotation )

  • Parameters:
    • annotation Some annotation.
  • Returns: The groups appropriate for the annotation. Done using known TUIs for the annotation.

Compares two groups for the most descriptive/accurate. e.g. Procedure is before Phenomenon.

static public SemanticGroup getBestGroup( final IdentifiedAnnotation annotation )

  • Parameters:
    • annotation Some annotation.
  • Returns: The most appropriate group for the annotation. Done using known TUIs for the annotation.

    • groups collection of groups.
  • Returns: The most appropriate group for the annotation.

static private SemanticGroup getBestTypeIdGroup( final IdentifiedAnnotation annotation )

Gets the best group based upon internal cTAKES type code for a group. These were old constants that shouldn't be used. However, an annotation may have a type id but no TUIs.

  • Parameters:
    • annotation -
  • Returns: the group based upon a type id set in the annotation.
