public String getLongName()

• Returns: Long name for the group. e.g. "Disease/Disorder" or "Medication".
  
  

public Class<? extends IdentifiedAnnotation> getCtakesClass()

• Returns: the cTAKES java / type system class that represents the group.
  
  

public Function<JCas, ? extends IdentifiedAnnotation> getCreator()

• 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.
• Returns: the group with the given code.
  
  

static public SemanticGroup getGroup( final String name )

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

static public SemanticGroup getGroupFromOld( final String name )

• Parameters:
  • name old name for a group. These were old constants that shouldn't be used.
• 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.
  
  

static private final class BestGrouper implements Comparator<SemanticGroup>

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.
  
  

static public SemanticGroup getBestGroup( final Collection<SemanticGroup> groups )

• Parameters:
  • 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.
