Chinese Information Extraction
Project description
CNN4IE
中文信息抽取工具。使用CNN的不同变体进行信息抽取,未来会持续加入不同模型。该项目使用pytorch,python开发。
CNN4IE根据CNN的各种改进版本,对不同模型块进行融合,并将其用于中文信息抽取中。

Evaluate
评估采用的是P、R、F1、PPL等。评估方法可利用scikit-learn中的precision_recall_fscore_support或classification_report。
Install
- 安装:pip install CNN4IE
- 下载源码:
git clone https://github.com/jiangnanboy/CNN4IE.git
cd CNN4IE
python setup.py install
通过以上两种方法的任何一种完成安装都可以。如果不想安装,可以下载github源码包
Dataset
这里利用data(来自人民日报,识别的是[ORG, PER, LOC, T, O])中的数据进行训练评估,模型1的训练及评估结果(分为带预训练向量和不带预训练向量的训练结果)见examples/mlrescnn(其它模型可自行运行评估)。
预训练embedding向量:sgns.sogou.char.bz2
数据集的格式见data,分为train与dev,其中source与target为中文对应的实体标注。
数据被处理成csv格式。
Todo
持续加入更多模型......
