Text Processing Implementation

[whitmo]

Text Processing Module

Overview

This PR implements a comprehensive text processing module that provides essential functionality for working with text data in the vector store. The implementation follows both Documentation-Driven Development (DDD) and Test-Driven Development (TDD) principles.

Features

Text Tokenization

• Flexible tokenization strategies
• Custom tokenizer configuration
• Support for different languages and formats

Text Chunking

• Multiple chunking strategies:
  • Fixed-size chunking
  • Paragraph-based chunking
  • Semantic chunking based on content
• Configurable chunk sizes and overlaps

Metadata Extraction

• Automatic extraction of metadata from text
• Support for custom metadata fields
• Integration with document processing

Text Analysis

• Text similarity calculation using Levenshtein distance
• Keyword extraction from text content
• Text summarization capabilities

Implementation Details

Documentation-Driven Development

The implementation follows the specifications outlined in the implementation plan:

Each feature was designed based on these requirements, with a focus on flexibility and extensibility.

Test-Driven Development

The implementation was guided by comprehensive tests:

• Unit tests for all pure functions
• Integration tests for the text processing module
• Tests for different chunking strategies
• Tests for metadata extraction and text analysis

All tests are passing, ensuring the reliability of the implementation.

Technical Details

Architecture

• Pure functions for core text processing operations
• Modular design for easy extension
• Clear separation of concerns

Performance Considerations

• Efficient algorithms for text processing
• Minimal memory footprint
• Optimized for large text documents

Next Steps

After merging this PR, the text processing module can be integrated with:

1. The vector store for improved document indexing
2. The search functionality for better query processing
3. The MCP server for enhanced knowledge management

Dependencies

• Added uuid crate for document ID generation

Testing

All tests are passing, including:

• 7 integration tests in
• 5 unit tests in the module's test suite
