Definition
Paraphrasing in Natural Language Processing involves generating alternative expressions for a given input text while preserving its original semantic meaning. It is crucial for reducing plagiarism, improving readability, and enhancing data diversity for training models. Techniques range from simple synonym substitution to complex neural sequence-to-sequence transformations. Effective paraphrasing requires a deep understanding of context, syntax, and semantics to ensure the rewritten text remains coherent and accurate relative to the source material.
