Have you ever tried reading a 200-page research paper and given up on the 5th page?
Honestly, we have all been there. Whether it’s a dense academic paper, a detailed 90-slide business report, or a lengthy user manual, PDFs give you a hard time. Annual reports, mainly from the large corporations, can have an average of 186 pages, as stated in a report of the FTSE 350 Companies. Even the user manuals, especially those published by Audi A3, can take approximately 11 hours and 45 minutes to read.
Enter AI. When you have tools that summarize lengthy PDFs with the help of AI, you get essential portions quickly. These tools function like super smart assistants that read, understand and bring out the core points of the PDF on your behalf. This makes reading documents less painful and saves time.
In this blog, you will learn how AI-powered PDF summarization happens and a step-by-step guide to summarize PDFs using one of the best AI PDF tools. So, let’s dig in.
What is AI-powered PDF summarization?
Before we head to the steps to summarize PDFs, getting the basics right is essential. AI summarization is the mechanism by which you can turn long-form documents and content into bite-sized insights with the help of artificial intelligence. Here are the two ways to approach AI-powered PDF summarization:
- Extractive summarization: The AI scans the whole document and lifts crucial portions. So, there’s no editing. You won’t get anything customized in extractive summarization. Indeed, it is a fast approach, but it may sound robotic.
- Abstractive summarization: This is a more innovative approach where AI reads the document, understands it and rephrases the content in a humanized format to make more sense. After scanning your PDF document, abstractive summarization identifies the key sections, uses NLP to understand the context and generates a digestible summary.
How does AI summarize a PDF?
AI PDF summarizers use certain technological mechanisms to connect the dots and help you with crisp briefs of lengthy PDFs. Here’s what goes on:
- OCR: Optical Character Recognition or OCR scans the images of a document and produces text in a digestible format.
- NLP: Natural Language Processing helps the AI tool understand what the PDF document is all about. It also figures out the tone, style, and language.
- Summary generation: These tools either choose an abstractive or an extractive approach to craft a summary.
- Structurization: After AI PDF summarizer tools have figured out what the document is all about, it lays its hands on imparting a readable structure to the summary.
- Output: While some tools generate only a summary, some others customize responses according to your needs.
