Elinor IR Evaluation Library

Elinor is a specialized evaluation library written in the Rust programming language, designed specifically for Information Retrieval (IR) systems. The library provides developers and researchers with a robust set of tools to calculate critical performance metrics such as Precision, Mean Average Precision (MAP), Mean Reciprocal Rank (MRR), and Normalized Discounted Cumulative Gain (nDCG). It is an open-source project hosted on platforms like GitHub and Crates.io.

The project draws its intellectual inspiration from the foundational works of Japanese researchers in the field, specifically Professor Tetsuya Sakai of Waseda University. The library serves as a modern tool to implement complex statistical tests like Student’s t-test and Tukey HSD tests for comparing IR system performances. As an open-source software component, it is developed and maintained by independent contributors under the MIT or Apache 2.0 licensing models, ensuring it remains accessible to the global engineering community.
