Stem vs lemma
| Word | Stem | Lemma |
|---|---|---|
| studies | studi | study |
| caring | car | care |
Remember

| Stop words: a, the, is |
| Lemma is always a real word |
Stemming can turn caring into car. Here is why. Stemming cuts endings. Studies becomes studi, not a real word. Lemmatisation gives study and care. Remember. Tokens are pieces of text. Stop words are removed. A lemma is a real word.
