@Internal
public class BioNLP2004NameSampleStream
extends Object
implements ObjectStream<NameSample>

A sample stream for the training files of the BioNLP/NLPBA 2004 shared task.

The data contains five named entity types:

• DNA
• RNA
• protein
• cell_type
• cell_line

Data can be found on this website, or in this repository.

The BioNLP/NLPBA 2004 data were originally published here:

http://www-tsujii.is.s.u-tokyo.ac.jp/GENIA/ERtask/report.html,

yet this page was gone when last checked in December 2022.

It looks like this repo contains a copy of the data located on the original page: The BioNLP 2004 seems to be related to http://www.geniaproject.org/shared-tasks/bionlp-jnlpba-shared-task-2004

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

BioNLP2004NameSampleStream

public BioNLP2004NameSampleStream(InputStreamFactory in,
 int types)
                           throws IOException

Initializes a BioNLP2004NameSampleStream.

Parameter:

in - The InputStreamFactory to use.

types - The types to use.

Löst aus:

IOException - Thrown if IO errors occurred during initialization.

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.
