# Introduction
In today’s digital world, the amount of data presented in documents is staggering. Businesses and organizations continually seek efficient methods to process, analyze, and derive insights from documents like invoices, contracts, and reports. Artificial intelligence (AI), particularly through document classification and extraction, emerges as a transformative solution. This guide delves into how AI can enhance these processes, the advantages of using vision models over traditional Optical Character Recognition (OCR), and how you can start leveraging these technologies using n8n.
## What is Document Classification and Document Extraction?
### Document Classification
Document classification refers to the method of categorizing documents based on their content. For instance, an AI model can distinguish between invoices, contracts, and reports, which allows systems to efficiently manage and retrieve documents based on their type.
### Document Extraction
Document extraction goes a step further by identifying and retrieving specific information from documents. For example, extracting due dates from invoices or the parties involved in a contract.
## Benefits of Using AI for Document Classification and Extraction
1. **Accuracy**: AI systems can learn from vast datasets, improving their accuracy over time, thus significantly reducing human error.
2. **Speed**: Automation of classification and data extraction can drastically expedite document processing times.
3. **Scalability**: AI can handle large volumes of documents simultaneously, making it suitable for growing businesses.
4. **Cost-Effectiveness**: Reducing the reliance on manual labor leads to cost savings in document processing.
## Vision Models vs. Traditional OCR
Historically, OCR has been the go-to technology for text recognition in images and scanned documents. However, it poses several limitations compared to modern vision models powered by deep learning.
### Advantages of Vision Models
– **Contextual Understanding**: Vision models are capable of understanding document layouts and the context of the text, leading to better extraction precision.
– **Handling Complex Layouts**: Unlike traditional OCR, vision models can process complex document layouts, capturing both text and structural elements such as tables or diagrams effectively.
– **Multimodal Capabilities**: These models can integrate visual elements along with text, enabling more comprehensive data extraction from documents that contain images, graphs, or infographics.
– **Improved Analytics**: Advanced models can provide insights into the classification characteristics of documents, aiding in continuous learning and adjustment of the classification process.
## Getting Started with n8n
To implement document classification and extraction effectively, n8n is a versatile tool that can automate your workflows, allowing easy integration with various AI services.
