Ranking Validation
This python package generates two ranking validation reports, one is a query level report that would contain information on the metrics provided as input and the overall metrics report which is a summarised version of query level report.
Introduction
The packages essentially compares two ranked lists at its core but scales it to a dataframe and automates the process of comparing two ranked lists for different queries for different set of metrics and at different cutoffs.
Usage
Installation using pip
pip install rank-validation
Getting the validation report
from rank_validation.validation_generator import get_metrics_report
query_report, overall_report = get_metrics_report(df, truth item column, truth score column, pred item col, metrics, cutoff)
Current version supports the following metrics:
- ndcg
- kendall_tau
- recall
- rbo
Note : rbo might run into errors if : len(set(ground_truth_items)) != len(set(predicted_items)), so if rbo gives an
error, try generating the report with other metrics available.
