# Class GermEval2014NameSampleStream

java.lang.Object
opennlp.tools.formats.GermEval2014NameSampleStream

All Implemented Interfaces:
  `AutoCloseable`, `opennlp.tools.util.ObjectStream<opennlp.tools.namefind.NameSample>`

@Internal public class GermEval2014NameSampleStream extends Object implements opennlp.tools.util.ObjectStream<opennlp.tools.namefind.NameSample>
Parser for the GermEval 2014 Named Entity Recognition Shared Task data.

The data is in a tab-separated format with four columns:

1. Token index (1-based per sentence)
2. Token text
3. Outer named entity tag (IOB2 scheme)
4. Nested/embedded named entity tag (IOB2 scheme)

Comment lines starting with `#` mark document boundaries and contain source URL and date metadata. Blank lines separate sentences.

The data uses four main entity types: Person (PER), Location (LOC), Organization (ORG) and Other (OTH), with additional `deriv` and `part` suffixes for derived forms and name parts respectively.

Since `NameSample` does not support overlapping spans, this stream requires selecting either the `outer` or `inner` annotation layer via a `GermEval2014NameSampleStream.NerLayer` parameter.

Data can be found on this web site.

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