Class Lemmatizer

java.lang.Object

com.exalead.linguistic.v10.SemanticProcessor

com.exalead.linguistic.v10.Lemmatizer

All Implemented Interfaces:

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

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

Produces lemmas for each noun and adjective in the document contexts. A lemma is the semantic root of a word that has different inflections. For instance, a lemma of geese is goose.
This processor is mostly used as a helper for other processors (like Ontology Matcher, or Semantic Extractor), which need to perform lemmatized matches.
It generates Annotations as follows:

• "lemma": normalized lemmatized form of the word (singular/masculine)
• "lemma_lowercase": lemmatized form of the word (singular/masculine)
• "fsingular": normalized singular form of the word
• "fsingular_lowercase": singular form of the word
• "masculine": if the token is a masculine word
• "feminine": if the token is a feminine word
• "neuter": if the token is neuter
• "singular": if the word is singular
• "plural": if the word is plural
• "unnumbered": if the word is unnumbered
• "pos": the static Part of Speech
