## What is Document Classification?
Document classification is the process of automatically categorizing documents into predefined classes or categories. This involves training machine learning models on labeled datasets, enabling them to recognize patterns and classify new documents accordingly. Some common applications include:
– **Email filtering**: Sorting emails into spam or important categories.
– **Content categorization**: Classifying articles or papers based on topics or genres.
## What is Document Extraction?
Document extraction refers to the process of automatically retrieving specific information from unstructured documents. This can include:
– **Data extraction**: Pulling out relevant fields like names, dates, or amounts from invoices.
– **Text extraction**: Collecting text from scanned documents or PDFs for further processing.
## Benefits of Using AI for Document Processing
– **Increased Accuracy**: AI algorithms can minimize errors associated with manual data entry and traditional OCR methods.
– **Scalability**: AI solutions can handle large volumes of documents seamlessly, making them ideal for businesses with high data processing needs.
– **Faster Processing**: Automating document processing can lead to significant time savings and faster customer responses.
## Why Choose Vision Models Over Traditional OCR?
While traditional OCR methods have been widely used for document scanning, AI vision models present multiple advantages:
### 1. Enhanced Understanding of Context
– Vision models utilize deep learning to not only recognize text but also understand the context in which it appears. This enables better extraction of relevant data and understanding of document structures.
### 2. Improved Accuracy in Complex Layouts
– AI vision models can handle complex document layouts with multiple columns, images, and graphics, something traditional OCR struggles with.
### 3. Support for Diverse Formats
– Vision models can extract information from images, scanned documents, and PDFs without requiring specific formatting, making them versatile across different types of documents.
## Getting Started with n8n
