To apply lemmatization using WordNetLemmatizer in NLTK for preprocessing generative AI data, you can refer to the following steps:
- Tokenize the Text: Split the text into individual tokens (words).
- Lemmatize: Use WordNetLemmatizer to convert words into their base forms (lemmas).
- Use POS Tags: Optionally, provide part-of-speech (POS) tags to improve lemmatization accuracy.
Here is the code reference you can refer to:
In the above code, we are using the following:
- Tokenization: The text is split into words using word_tokenize.
- POS Tagging: nltk.pos_tag is used to get part-of-speech tags for each word, which help in determining the correct lemma.
- Lemmatization: The WordNetLemmatizer is used to convert each word into its base form, considering its part-of-speech tag.
Hence, this preprocessing step is useful for generative AI tasks like text generation, as it ensures words are reduced to their root forms, improving consistency and model efficiency.
