Key Phrase Extraction is the appropriate technique to apply when identifying main talking points in documents using natural language processing. This method focuses on automatically extracting significant phrases that represent the core topics or ideas present in a text. By isolating and highlighting these key phrases, you can summarize the document's main concepts effectively, which is particularly useful for tasks such as summarization and content analysis.
