implements ObjectStream<NameSample>

Parser for the Dutch and Spanish ner training files of the CONLL 2002 shared task.

The Dutch data has a DOCSTART tag to mark article boundaries, adaptive data in the feature generators will be cleared before every article.
The Spanish data does not contain article boundaries, adaptive data will be cleared for every sentence.

The data contains four named entity types: Person, Organization, Location and Misc.

Data can be found on this web site.

Note: Do not use this class, internal use only!

Conll02NameSampleStream

public Conll02NameSampleStream(Conll02NameSampleStream.LANGUAGE lang,
 ObjectStream<String> lineStream,
 int types)

Initializes a Conll02NameSampleStream.

Parameter:

lang - The language of the CONLL 02 data.

lineStream - An ObjectStream<String> over the lines in the CONLL 02 data file.

types - The entity types to include in the Name Sample object stream.

Conll02NameSampleStream

public Conll02NameSampleStream(Conll02NameSampleStream.LANGUAGE lang,
 InputStreamFactory in,
 int types)
                        throws IOException

Initializes a Conll02NameSampleStream.

Parameter:

lang - The language of the CONLL 02 data.

in - The InputStreamFactory for the input file.

types - The entity types to include in the Name Sample object stream.

Löst aus:

IOException - Thrown if IO errors occurred.

Methodendetails

read

public NameSample read()
                throws IOException

Beschreibung aus Schnittstelle kopiert: ObjectStream

Returns the next ObjectStream object. Calling this method repeatedly until it returns null will return each object from the underlying source exactly once.

Angegeben von:

read in Schnittstelle ObjectStream<NameSample>

Gibt zurück:

The next object or null to signal that the stream is exhausted.

Löst aus:

IOException - Thrown if there is an error during reading.

reset

public void reset()
           throws IOException,
UnsupportedOperationException

Beschreibung aus Schnittstelle kopiert: ObjectStream

Repositions the stream at the beginning and the previously seen object sequence will be repeated exactly. This method can be used to re-read the stream if multiple passes over the objects are required.

The implementation of this method is optional.

Angegeben von:

reset in Schnittstelle ObjectStream<NameSample>

Löst aus:

IOException - Thrown if there is an error during resetting the stream.

UnsupportedOperationException - Thrown if the reset() is not supported. By default, this is the case.

close

public void close()
           throws IOException

Beschreibung aus Schnittstelle kopiert: ObjectStream

Closes the ObjectStream and releases all allocated resources. After close was called, it's not allowed to call ObjectStream.read() or ObjectStream.reset().

Angegeben von:

close in Schnittstelle AutoCloseable

Angegeben von:

close in Schnittstelle ObjectStream<NameSample>

Löst aus:

IOException - Thrown if there is an error during closing the stream.
