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

Parser for the Italian NER training files of the Evalita 2007 and 2009 NER shared tasks.

The data does not contain article boundaries, adaptive data will be cleared for every sentence.

Named Entities are annotated in the IOB2 format (as used in CoNLL 2002 shared task)

The Named Entity tag consists of two parts: 1. The IOB2 tag: 'B' (for 'begin') denotes the first token of a Named Entity, I (for 'inside') is used for all other tokens in a Named Entity, and 'O' (for 'outside') is used for all other words; 2. The Entity type tag: PER (for Person), ORG (for Organization), GPE (for Geo-Political Entity), or LOC (for Location).

Each file consists of four columns separated by a blank, containing respectively the token, the Elsnet PoS-tag, the Adige news story to which the token belongs, and the Named Entity tag.

Data can be found on this web site.

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

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.
