Summary
Pyversity is a lightweight Python library designed to diversify search and retrieval results by re-ranking them to reduce redundancy while maintaining relevance. It implements popular diversification algorithms including MMR, MSD, DPP, and Cover through a unified API, with NumPy as its only dependency, making it fast and efficient for improving result diversity in retrieval systems.
Key quotes
· 4 pulledPyversity is a fast, lightweight library for diversifying retrieval results.
Retrieval systems often return highly similar items. Pyversity efficiently re-ranks these results to encourage diversity, surfacing items that remain relevant but less redundant.
It implements several popular diversification strategies such as MMR, MSD, DPP, and Cover with a clear, unified API.
The only dependency is NumPy, making the package very lightweight.
