Lemmatization Fallback Strategy

This module defines the LemmatizationFallbackStrategy protocol, which represents the interface for lemmatization fallback strategies in the Simplemma library. LemmatizationFallbackStrategy are used as a fallback strategy when a token's lemma cannot be determined using other lemmatization strategies.

Classes

LemmatizationFallbackStrategy

Bases: Protocol

This protocol defines the interface for lemmatization fallback strategies in the Simplemma library. Fallback strategies are used when a token's lemma cannot be determined using other lemmatization strategies.

Note: This protocol should be implemented by concrete fallback strategy classes. Concrete implementations of this protocol should provide a concrete implementation for the get_lemma method.
