Class AncoraSpanishHeadRules

All Implemented Interfaces:
GapLabeler, HeadRules, SerializableArtifact

public class AncoraSpanishHeadRules extends Object implements HeadRules, GapLabeler, SerializableArtifact
Class for storing the Ancora Spanish head rules associated with parsing. In this class headrules for noun phrases are specified. The rest of the rules are in opennlp-tools/lang/es/parser/es-head-rules

NOTE: This class has been adapted from

The main change is the constituents search direction in the first for loop.

Note also the change in the return of the getHead() method: In the lang.en.HeadRules class: return constituents[ci].getHead(); Now: return constituents[ci];

Other changes include removal of deprecated methods.

    • getHead

      public Parse getHead(Parse[] constituents, String type)
      Description copied from interface: HeadRules
      Retrieves the head constituent for the specified constituents of given type.
      Specified by:
      getHead in interface HeadRules
      constituents - The constituents which make up a constituent of the specified type.
      type - The type of a constituent which is made up of the constituents.

    • labelGaps

      public void labelGaps(Stack<Constituent> stack)
      Description copied from interface: GapLabeler
      Labels constituents found in the stack with gap labels if appropriate.
      Specified by:
      labelGaps in interface GapLabeler
      stack - The Stack of un-completed constituents.
    • serialize

      public void serialize(Writer writer) throws IOException
      Serializes the head rules via a Writer in a format suitable for loading the head rules again. The encoding must be taken into account while working with the writer and reader.

      Once the entries have been written, the writer is flushed.

      Note: The writer remains open after this method returns.

      writer - The Writer to write the head rules to.

    • equals

      public boolean equals(Object obj)
      equals in class Object
    • getArtifactSerializerClass

      public Class<?> getArtifactSerializerClass()
      Description copied from interface: SerializableArtifact
      Retrieves the class which can serialize and recreate this artifact.

      Note: The serializer class must have a public zero argument constructor or an exception is thrown during model serialization/loading.

      Specified by:
      getArtifactSerializerClass in interface SerializableArtifact
      The corresponding ArtifactSerializer class.
