## Section 1: Understanding Document Classification and Extraction
### Subsection 1.1: What is Document Classification?
Document classification involves the automatic categorization of documents based on their content. AI algorithms analyze text and context to assign labels or categories, making it easier to manage large volumes of documents.
### Subsection 1.2: What is Document Extraction?
Document extraction refers to the process of retrieving relevant data from documents. This can include extracting specific fields, tables, or even entire sections of text, automating what would otherwise be a time-consuming manual process.
## Section 2: The Limitations of Traditional OCR
Traditional OCR systems have been widely used for text recognition, but they come with several limitations:
– **Accuracy Issues**: OCR struggles with varying fonts, layouts, and languages, leading to errors in data extraction.
– **Context Understanding**: OCR does not understand content context well, which can affect classification accuracy.
– **Manual Pre-processing**: Often requires significant pre-processing of documents to achieve acceptable results.
## Section 3: The Benefits of Using Vision Models
Utilizing AI vision models can enhance both classification and extraction processes. Here’s how:
1. **Higher Accuracy**: Vision models leverage deep learning and can recognize patterns and features beyond mere text. This results in improved accuracy over traditional OCR methods.
2. **Contextual Understanding**: AI models can comprehend document context, enabling them to categorize documents more intuitively and extract pertinent data effectively.
3. **Versatile Handling of Formats**: Vision models can process various document types and formats (e.g., images, PDFs), reducing the need for document standardization.
4. **Reduced Manual Intervention**: With advanced capabilities, AI models minimize manual document handling, streamlining workflows and saving time.
## Section 4: Getting Started with Document Classification and Extraction Using n8n
