Negating a sentence

Question

I'm looking for algorithm or function to negate a sentence, for example: input: "The Belgian kid like chocolate" output: "The Belgian kid doesn't like chocolate" Does anyone knows an Algorithm or ML model to perform this task?

Answer 1

Popular language models can be fine-tuned for this task. This might be a bit of an overkill, but I was personally very impressed by this example of few-shot learning teaching Google T5 model to negate a sentence with a reasonable success rate with just a dozen samples:

Answer 2

For a rule-based negation approach, you can take a look at the Python module negate¹.
