I-measureを今時動かす

Last updated at Posted at 2023-07-05

文法誤り訂正の評価尺度 I-measure (https://github.com/mfelice/imeasure) を今時動かす方法を紹介します。どうも、python2が使われていた時代は普通に動いていたみたいなんですが、現在python2で動かそうと思うと少し難しいです。

python 2.7の環境を用意

conda create -n p27 python=2.7
conda activate p27

elementtreeをインストール

公式のリンクからwgetするとファイルが壊れる。

wget https://src.fedoraproject.org/repo/pkgs/python-elementtree/elementtree-1.2.6-20050316.tar.gz/md5/e1b21716be8bfff8bf192fc3880ad008/elementtree-1.2.6-20050316.tar.gz
tar zxvf elementtree-1.2.6-20050316.tar.gz
cd elementtree-1.2.6-20050316
python setup.py install

nltkをインストール

pipだと入らない。

conda install nltk -c intel

numpyをインストール

python -m pip install numpy

M2をxmlに変換

python m2_to_ixml.py -in:official-2014.combined.m2 -out:official-2014.combined.xml

I-measureを実行

$ python ieval.py -ref:official-2014.combined.xml -hyp:AMU -nomix
---------------------------------------------------------------------------------------------------------------------
Hypothesis file    : AMU
Gold standard file : official-2014.combined.xml
Maximising metric  : WACC - CORRECTION
Optimise for       : SENTENCE
WAcc weight        : 2.0
F beta             : 1.0
---------------------------------------------------------------------------------------------------------------------

OVERALL RESULTS
---------------------------------------------------------------------------------------------------------------------
Aspect            TP      TN      FP      FN     FPN       P       R  F_1.00     Acc   Acc_b    WAcc  WAcc_b       I 
---------------------------------------------------------------------------------------------------------------------
Detection        620   27350     752    2158       0   45.19   22.32   29.88   90.58   90.99   88.65   90.99   -2.57
Correction       484   27350     888    2294     136   35.28   17.42   23.33   90.14   90.99   87.99   90.99   -3.30

-nomixをつけると元の論文と値が変わってしまう気がするんですが、つけないと数百GBのメモリを使い果たした上にkillされてしまったので、どうしたらいいのかよくわかりません。
