Rasa NLU a natural language parser for bots

# Rasa NLU GQ
Rasa NLU (Natural Language Understanding) 是一个自然语义理解的工具，举个官网的例子如下：

> *"I'm looking for a Mexican restaurant in the center of town"*

And returning structured data like:

```
intent: search_restaurant
entities:
- cuisine : Mexican
- location : center
```

## Intent of this project
这个项目的目的和初衷，是由于官方的rasa nlu里面提供的components和models并不能满足实际需求，有些models精确度不是很乐观。所以我自定义了几个components，而为什么不直接提个pr到rasa nlu官网呢，因为要写太多test。所以在我自己的github上开源并发布到Pypi上，这样后续也能不断往里面填充和优化模型，方便别人也方便自己。

## New features
目前新增了两个特性，支持版本为rasa-nlu-gao==v0.1.2
- 新增了实体识别的模型，一个是bilstm+crf，一个是idcnn+crf膨胀卷积模型，对应的yml文件配置如下：
```
language: "zh"

pipeline:
- name: "tokenizer_jieba"

- name: "intent_featurizer_count_vectors"
token_pattern: '(?u)\b\w+\b'
- name: "intent_classifier_tensorflow_embedding"

- name: "ner_bilstm_crf"
lr: 0.001
char_dim: 100
lstm_dim: 100
batches_per_epoch: 10
seg_dim: 20
num_segs: 4
batch_size: 200
tag_schema: "iobes"
model_type: "bilstm" # 模型支持两种idcnn膨胀卷积模型或bilstm双向lstm模型
clip: 5
optimizer: "adam"
dropout_keep: 0.5
steps_check: 100
```
- 新增了jieba词性标注的模块，可以方便识别名字，地名，机构名等等jieba能够支持的词性，对应的yml文件配置如下：
```
language: "zh"

pipeline:
- name: "tokenizer_jieba"
- name: "ner_crf"
- name: "jieba_pseg_extractor"
part_of_speech: ["nr", "ns", "nt"]
- name: "intent_featurizer_count_vectors"
OOV_token: oov
token_pattern: '(?u)\b\w+\b'
- name: "intent_classifier_tensorflow_embedding"
```

## Quick Install
```
pip install rasa-nlu-gao
```

## 🤖 Running of the bot
To train the NLU model:
```
python -m rasa_nlu_gao.train -c sample_configs/config_embedding_bilstm.yml --data data/examples/rasa/rasa_dataset_training.json --path models
```

To run the NLU model:
```
python -m rasa_nlu_gao.server -c sample_configs/config_embedding_bilstm.yml --path models
```
