Class CompletePreprocessingPipeline

java.lang.Object

org.carrot2.text.preprocessing.pipeline.BasicPreprocessingPipeline

org.carrot2.text.preprocessing.pipeline.CompletePreprocessingPipeline

All Implemented Interfaces:

IPreprocessingPipeline

@Bindable(prefix="PreprocessingPipeline")
public class CompletePreprocessingPipeline
extends BasicPreprocessingPipeline

Performs a complete preprocessing on the provided documents. The preprocessing consists of the following steps:

1. Tokenizer.tokenize(PreprocessingContext)
2. CaseNormalizer.normalize(PreprocessingContext)
3. LanguageModelStemmer.stem(PreprocessingContext)
4. StopListMarker.mark(PreprocessingContext)
5. PhraseExtractor.extractPhrases(PreprocessingContext)
6. LabelFilterProcessor.process(PreprocessingContext)
7. DocumentAssigner.assign(PreprocessingContext)
