Namespace NOpenNLP.Tools.Chunker
Package related to finding non-recursive syntactic annotation such as noun phrase chunks.
Classes
- ChunkSample
Class for holding chunks for a single unit of text.
- ChunkSampleStream
Parses the conll 2000 shared task shallow parser training data.
Data format is specified on the conll page:
http://www.cnts.ua.ac.be/conll2000/chunking/
- ChunkerEvaluator
The ChunkerEvaluator measures the performance of the given IChunker with the provided reference ChunkSamples.
- ChunkerEventStream
Class for creating an event stream out of data files for training a chunker.
- ChunkerME
The class represents a maximum-entropy-based chunker. Such a chunker can be used to find flat structures based on sequence inputs such as noun phrases or named entities.
- ChunkerModel
The ChunkerModel is the model used by a learnable IChunker.
- DefaultChunkerContextGenerator
Features based on chunking model described in Fei Sha and Fernando Pereira. Shallow parsing with conditional random fields. In Proceedings of HLT-NAACL 2003. Association for Computational Linguistics, 2003.
Interfaces
- IChunker
The interface for chunkers which provide chunk tags for a sequence of tokens.
- IChunkerContextGenerator
Interface for the context generator used in syntactic chunking.
