Class SnowballStemmer

java.lang.Object

com.exalead.indexing.analysis.v10.SemanticProcessor

com.exalead.indexing.analysis.v10.SnowballStemmer

All Implemented Interfaces:

com.exalead.util.Checkable, java.io.Serializable

public class SnowballStemmer
extends SemanticProcessor
implements com.exalead.util.Checkable, java.io.Serializable

Creates the stemmed form of each word. This uses the Snowball stemming algorithms.
This processor is mostly used as a helper for other processors (like Ontology Matcher, or Semantic Extractor), which need to perform stemmed matches.
Annotations generated:

• "stem"
