Natural Language Processing: How widely used are context-free grammars in abstractive summarizations?
Can you give me an example of how context-free grammars are used in abstractive summarizations?
Sure. In abstractive summarization, the aim is to generate a summary that captures the main idea of a document in a concise and natural way. Context-free grammars can be used to identify the key concepts and relationships between them, which can then be used to generate a summary that reflects the overall meaning of the document.
