Overview

Initial project setup and implementation of core functionality for semantic similarity search using Jina AI's APIs.

Key Activities

  1. Created the core JinaSimilarity class in jina_similarity.py with the following features:

    • Token counting using tiktoken
    • Embedding generation using Jina AI's Embeddings API
    • Similarity computation using cosine similarity
    • Error handling for token limit violations

  2. Implemented the markdown segmenter in markdown_segmenter.py:

    • Segmentation of markdown documents using Jina AI's Segmenter API
    • Command-line interface for easy usage

  3. Developed a test script (test_similarity.py) with:

    • Command-line argument parsing
    • File reading functionality
    • Verbose output option for debugging
    • Error handling

  4. Created sample files for testing:

    • sample_chunk.txt: Contains a paragraph about pangrams
    • sample_query.txt: Contains a question about pangrams

Insights

  • Jina AI's embedding model (jina-embeddings-v3) provides high-quality embeddings for semantic search
  • The token limit of 8,192 tokens is sufficient for most use cases, but longer documents need segmentation
  • Normalizing embeddings simplifies similarity computation (dot product equals cosine similarity)
  • Separating segmentation from similarity computation provides better modularity

Challenges

  • Ensuring proper error handling for API failures
  • Managing token limits for large documents
  • Balancing between chunking granularity and semantic coherence

Next Steps

  1. Add tiktoken to requirements.txt
  2. Implement caching for embeddings to reduce API calls
  3. Add batch processing capabilities for multiple chunks/queries
  4. Create comprehensive documentation and usage examples
  5. Develop integration tests for reliability testing
