Class EvalitaNameSampleStream
- All Implemented Interfaces:
AutoCloseable,ObjectStream<NameSample>
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.

Method Details
-
read
Description copied from interface:ObjectStreamReturns the nextObjectStreamobject. Calling this method repeatedly until it returnsnullwill return each object from the underlying source exactly once.- Specified by:
readin interfaceObjectStream<NameSample>- Returns:
- The next object or
nullto signal that the stream is exhausted. - Throws:
IOException- Thrown if there is an error during reading.
-
reset
Description copied from interface:ObjectStreamRepositions 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.
- Specified by:
resetin interfaceObjectStream<NameSample>- Throws:
IOException- Thrown if there is an error during resetting the stream.UnsupportedOperationException- Thrown if thereset()is not supported. By default, this is the case.
-
close
Description copied from interface:ObjectStreamCloses theObjectStreamand releases all allocated resources. After close was called, it's not allowed to callObjectStream.read()orObjectStream.reset().- Specified by:
closein interfaceAutoCloseable- Specified by:
closein interfaceObjectStream<NameSample>- Throws:
IOException- Thrown if there is an error during closing the stream.
