Lemma Identification

A benchmark to evaluate a model's ability to identify the lemma (base form) of a given word. The lemma is the dictionary form: - For nouns: the singular form (e.g., "cats" → "cat") - For verbs: the infinitive form without "to" (e.g., "running" → "run") - For adjectives: the positive form (e.g., "better" → "good")
