Install(安装)

pip install Keras-TextClassification

step2: download and unzip the dir of 'data.rar', 地址: https://pan.baidu.com/s/1I3vydhmFEQ9nuPG2fDou8Q 提取码: rket
       cover the dir of data to anaconda, like '/anaconda/3.5.1/envs/tensorflow13/Lib/site-packages/keras_textclassification/data'
step3: goto # Train&Usage(调用) and Predict&Usage(调用)

run(运行, 以FastText为例)

- 1. 进入keras_textclassification/m01_FastText目录，
- 2. 训练: 运行 train.py,   例如: python train.py
- 3. 预测: 运行 predict.py, 例如: python predict.py
- 说明: 默认不带pre train的random embedding，训练和验证语料只有100条，完整语料移步下面data查看下载

run(多标签分类/Embedding/test/sample实例)

- bert,word2vec,random样例在test/目录下, 注意word2vec(char or word), random-word,  bert(chinese_L-12_H-768_A-12)未全部加载,需要下载
- multi_multi_class/目录下以text-cnn为例进行多标签分类实例，转化为multi-onehot标签类别，分类则取一定阀值的类
- sentence_similarity/目录下以bert为例进行两个句子文本相似度计算,数据格式如data/sim_webank/目录下所示

项目说明

• 1. 构建了base基类(网络(graph)、向量嵌入(词、字、句子embedding)),后边的具体模型继承它们，代码简单
• 2. keras_layers存放一些常用的layer, conf存放项目数据、模型的地址, data存放数据和语料, data_preprocess为数据预处理模块,
