s - an array of Entities

start - start of the sequence to concatenate

end - end of the sequence to concatenate

concatAttr

public static java.lang.String concatAttr(int id,
                                          Entity[] s)

Concatenate orth or base of a sequence of entities, adding space or not with respect to ns special entities.

Parameters:

id - attribute to concatenate (Attribute.ORTH or Attribute.BASE)

s - an array of Entities

getCommonValues

public static java.util.Set<java.lang.String> getCommonValues(Entity[] match,
                                                              int[] attrIds)

Get common values of specified attributes of specified entities.

unify

public static boolean unify(Entity[] match,
                            int[] attrIds)

Unify specified entities with respect to specified attributes.

getId

public java.lang.String getId()

getAttr

public java.lang.String getAttr(int id)

Get orthographic or base form of an entity.

Parameters:

id - Attribute.ORTH or Attribute.BASE

Returns:

orthographic or base form for segments and words, empty string for groups and special entities (ns, sb, se).

getSemHead

public Segment getSemHead()

Get semantic head of an entity.

Returns:

semantic head of a group, null otherwise

getSynHead

public Segment getSynHead()

Get syntactic head of an entity.

Returns:

semantic head of a group, null otherwise

Get group type.

Returns:

type of a group, null otherwise

getInterpretations

public java.util.Set<Interpretation> getInterpretations()

Get the set of interpretations.

Returns:

a set of interpretations for segments and words, null for groups and special entities (ns, sb, se).
