## What is Document Classification and Extraction?
Document classification involves sorting documents into predefined categories based on their content. Document extraction, on the other hand, involves pulling specific data from those documents. Both processes are integral in automating workflows and enhancing data management.
## Why Use AI for Document Classification?
Using AI in document classification enables organizations to:
– **Increase Accuracy**: AI models reduce human error in both classification and extraction tasks.
– **Handle Volume**: AI can process large volumes of documents rapidly, something manual methods struggle with.
– **Adaptability**: AI models can learn from new data, allowing for updates without extensive reprogramming.
## Benefits of Using Vision Models
While traditional OCR focuses primarily on text recognition, vision models offer several advantages:
– **Enhanced Contextual Understanding**: Vision models analyze the whole document layout, recognizing not just text but also images, tables, and signatures.
– **Improved Performance on Various Formats**: Unlike conventional OCR, which may struggle with complex layouts or poor-quality scans, vision models adapt better to diverse input data.
– **Integrated AI Capabilities**: Vision models can be combined with other AI functionalities such as Natural Language Processing (NLP) to improve understanding of the document content.
### Comparison of OCR vs. Vision Models
| Feature | Traditional OCR | Vision Models |
|————————————-|——————————–|——————————–|
| Text Recognition | High | High |
| Document Layout Understanding | Low | High |
| Versatility with Formats | Moderate | High |
| Adaptability to Different Inputs | Low | High |
| Processing Speed | Medium | Fast |
