Simple tool to predict text classes with various models.

Project description

# TextClassify

## Model

* fastText char
* fastText word
* CNN char embedding
* CNN word embedding
* CNN char & word embedding
* CNN + BiGRU + char & word embedding

## Segment Model

* pyltp
* jieba

## Embedding

* fastText (CBOW / skip-gram)
* gensim

char or word embedding

## Usage

```python
from text_classify import TextClassify

# default params
t = TextClassify()
text = ''
logtis = t.predict(text, precision='16')

# get index2label
t.index2label

# get top label
t.get_top_label(text, k=5, precision='16')
```
