Changed

Changed save in ranxhub.py to automatically save average metric scores.

Fixed a bug affecting make_comparable in run.py: runs were not sorted after this operation, resulting in wrong metrics computation afterwards.

[0.3.8] - 2023-05-01

Added

It is now possible to plot Interpolated Precision-Recall Curve. Click here for further details.

[0.3.7] - 2023-04-17

Added

Added make_comparable to run.py. It makes a run comparable to a given qrels whether the run misses results for queries appearing in the qrels or have results for additional queries, which are removed.
Added make_comparable parameter to evaluate.py.
Added make_comparable parameter to compare.py.

[0.3.5] - 2023-02-13

Fixed

Fixed a bug affecting Tukey's HSD Test: results from the test were not converted to proper dtypes from strings, causing the superscript reporting statistical significance differences in report.py to be wrong.

Changed tukey_hsd_test.py to use tukey_hsd provided by scipy.
ranx now requires python>=3.8.
ranx now requires scipy>=1.8.

Removed

Removed dependency from statsmodels.

[0.3.4] - 2022-11-22

Fixed

Fixed a bug affecting precision.py, recall.py, and f1.py: numba does not raise ZeroDivisionError, added a control to make sure zero is returned when no retrieved results are provided for a specific query.
Fixed a bug in f1.py: missing argument in function call.

[0.3.x] - 2022

Sorry, I have been lazy.

[0.2.13] - 2022-09-30

Fixed

Fixed a bug in posfuse.py: numba does not raise out of bounds error in some specific cases, added a control to make sure ranking positions with no associated probability get 0 probability.
Fixed a bug in baysfuse.py: as it uses log odds, which can be negative, comb_sum cannot be used. Added a odds_sum function to combine the log odds.

[0.2.12] - 2022-09-22

Fixed

Fixed a bug in data_structures/common.py:sort_dict_by_value that was preventing result list sorting to be consistent for documents with the same score.

[0.2.11] - 2022-09-21

Fixed

Fixed a bug in max_norm.py, min_max_norm.py, and sum_norm.py: min and max functions called on empty lists do not raise error in Numba causing downstream miscalculations.

Fixed a bug in condorcet.py: get_candidates raised error if no run had retrieved docs for a given query.

[0.2.9] - 2022-08-29

Fixed

Fixed a bug in report.py:Report: some metric labels were missing.
SciPy version explicitly stated in setup.py to avoid errors.

Changed

Qrels's save and from_file functions now automatically infer file extension. kind parameter can be used to override default behavior.
Qrels's save and from_file functions are now much faster with json files thanks to orjson.
Run's save and from_file functions now automatically infer file extension. kind parameter can be used to override default behavior.
Run's save and from_file functions are now much faster with json files thanks to orjson.
Two-sided Paired Student's t-Test is now the default statistical test used when calling compare. It is much faster than Fisher's and usually agrees with it.

[0.2.x] - 2022

Sorry, I have been lazy.

[0.1.14] - 2022-04-19

Fixed

Fixed a bug in report.py:Report.to_dict.

[0.1.13] - 2022-04-18

Added

Added from_ir_datasets to qrels.py. It allows loading qrels from ir_metadata.

[0.1.12] - 2022-04-04

Added

Added paired_student_t_test to statistical_testing.py.
Added stat_test parameter to compare. Defaults to fisher.
Added stat_test parameter to report. Defaults to fisher.

Changed

Report's to_latex function now takes into account the newly introduced stat_test parameter to correctly generating LaTeX tables' captions.
Report's to_dict function now takes into account the newly introduced stat_test parameter and adds it to the output dictionary.
Report's save function now takes into account the newly introduced stat_test parameter and adds it to the output JSON file.

[0.1.11] - 2022-02-15

Added

Added show_percentages parameter to Report. Defaults to False.
Added show_percentages parameter to compare. Defaults to False.
Added rounding_digits parameter to compare. Defaults to 3.
Added usage example notebooks for Google Colab.

Changed

[IMPORTANT] Qrels and Run now accept a Python Dictionary as initialization parameter and this is the preferred way of creating new instances for those classes. They also accept a name parameter. None of those is mandatory, so it should not break code based on previous ranx version although this could be changed in the future.
[BREAKING CHANGE] Qrels and Run save function type parameter renamed to kind to prevent it to be interpreted as the type Python utility function.
[BREAKING CHANGE] Qrels and Run save function now defaults to json instead of trec for the kind parameter (previously called type).
[BREAKING CHANGE] Qrels and Run from_file function type parameter renamed to kind to prevent it to be interpreted as the type Python utility function.
[BREAKING CHANGE] Qrels and Run from_file function now defaults to json instead of trec for the kind parameter (previously called type).
rounding_digits parameter of Report now defaults to 3.
Report's to_latex function now produces a simplified LaTeX table.
Various improvements to Report source code.
