## Introduction
In today’s data-driven world, businesses generate and receive vast amounts of documents daily. Processing this data manually can be tedious and error-prone. Fortunately, advancements in Artificial Intelligence (AI) now allow us to automate the classification and extraction of information from documents. In this guide, we’ll delve into the foundational concepts of AI for document classification and extraction, explore the benefits of using vision models over traditional Optical Character Recognition (OCR), and recommend n8n as an accessible tool to kickstart your journey into AI document processing.

## What is Document Classification?
Document classification is the process of categorizing documents into predefined groups based on their content. This can include sorting emails, invoices, contracts, and more. AI-based classification allows systems to learn from data, improving accuracy and efficiency over time. By leveraging natural language processing (NLP) and machine learning, businesses can automate this task, saving time and reducing human error.
## What is Document Extraction?
Document extraction refers to the ability to retrieve specific pieces of information from a document, such as extracting names, dates, or monetary values. AI technologies can automatically extract this data from various formats, including PDF, images, and office documents. This automation streamlines operations and enhances data management processes.
## Traditional OCR: A Brief Overview
Traditional Optical Character Recognition (OCR) technology has been widely used to convert different types of documents into editable and searchable data. While it serves its purpose, OCR primarily focuses on reading the text in an image. It has several limitations, including:
– Inability to understand the context or meaning of words.
– Frequent misinterpretation of handwritten and low-quality text.
– The requirement for precise layout formats, limiting its flexibility.
## The Rise of Vision Models
Vision models are a new wave in document processing using deep learning techniques to analyze images. Unlike traditional OCR, vision models can understand complex layouts, including text, images, and other graphical elements. They are trained to recognize patterns and learn contextual information, making them significantly more powerful.
## Benefits of Vision Models over Traditional OCR
The advantages of using vision models for document classification and extraction include:
– **Enhanced Accuracy:** Vision models provide better recognition rates by understanding context and structure.
– **Flexibility:** Capable of processing a variety of document formats—including scanned images and handwritten notes—without requiring strict layouts.
– **Multi-modal Capability:** Can analyze both visual elements (like images and graphs) and text in documents, enabling more holistic data extraction.
– **Reduced Need for Preprocessing:** Unlike traditional OCR systems relying heavily on clear text alignment, vision models can handle variants in the document structure with ease.
## Using n8n for Document Classification and Extraction
