Tips for Better AI Text Summarization

Text summarization by AI is a powerful tool to boost your productivity, but like any tool, it benefits from a bit of finesse to get the best results. Here are some tips to make your AI text summarization shine:

1. Understand the major ‘Why’

Before summarizing, ask yourself, ‘Why am I summarizing this?’ Are you distilling a lengthy report into a brief executive summary? Or maybe you're summarizing an article for a quick news update. Knowing the purpose helps you focus on what matters most.

2. Extract the key points

Think of text summarization like extracting the juiciest bits from a fruit salad. Look for the main ideas, important stats, and key arguments. For instance, when summarizing a news article about a major sporting event, focus on the final score, standout plays, and crucial turning points.

3. Trim the fat

AI can be a bit like a chef who wants to include every ingredient in a dish. Don't be afraid to trim unnecessary details. If you were summarizing a recipe for chocolate chip cookies, you'd skip the backstory about the chef's grandma and get straight to the ingredients and steps.

4. Keep the laser-like focus on clarity

Clear communication is vital. Imagine you're summarizing a complex scientific paper for a non-expert audience. Use simple language, avoid jargon, and provide context where needed.

5. Prioritize coherence

Your summary should read like a well-composed symphony, not a cacophony of random notes. Ensure that the sentences flow logically and that one point naturally leads to the next.

6. Polish with passion

Even the best writers revise their work. Review your AI-generated summary for accuracy and coherence. Imagine it as the art of polishing a treasured gemstone.

7. Be critical

AI is smart but not infallible. Just like a GPS can sometimes lead you astray, AI may occasionally misinterpret context or miss nuances. Always exercise your critical thinking skills.

8. Practice nonstop

Summarization is a skill. Enhance this skill through repetition. As you practice more, your proficiency grows. Start with simple tasks and work your way up to summarizing complex documents.
