# SongNet for Chinese Couplet(songnet-base-chinese-couplet) Model
SongNet中文对联仿写模型

`songnet-base-chinese-couplet` evaluate couplet test data:

The overall performance of SongNet on couplet **test**:

|input_text|predict|
|:--- |:--- |
|一句相思吟岁月</s>千杯美酒醉风情|<bos>一生只剩诗和酒</s>满腹无关雪与梅</s>|

在Couplet测试集上生成结果满足字数相同、词性对齐、词面对齐、形似要求,针对性的SongNet网络结构,在语义对仗工整和平仄合律上的效果明显优于T5和GPT2等模型。

SongNet的网络结构:

## Usage

本项目开源在文本生成项目:[textgen](https://github.com/shibing624/textgen),可支持SongNet模型,通过如下命令调用:

Install package:
```shell
pip install -U textgen
```

```python
import sys

sys.path.append('..')
from textgen.language_modeling import SongNetModel


model = SongNetModel(model_type='songnet', model_name='songnet-base-chinese-couplet')
sentences = [
    "严蕊<s1>如梦令<s2>道是梨花不是。</s>道是杏花不是。</s>白白与红红,别是东风情味。</s>曾记。</s>曾记。</s>人在武陵微醉。",
    "<s1><s2>一句相思吟岁月</s>千杯美酒醉风情",
    "<s1><s2>几树梅花数竿竹</s>一潭秋水半屏山"
    "<s1><s2>未舍东江开口咏</s>且施妙手点睛来",
    "<s1><s2>一去二三里</s>烟村四五家",
]
print("inputs:", sentences)
print("outputs:", model.generate(sentences))
sentences = [
    "<s1><s2>一句____月</s>千杯美酒__情",
    "<s1><s2>一去二三里</s>烟村__家</s>亭台__座</s>八__枝花",
]
print("inputs:", sentences)
print("outputs:", model.fill_mask(sentences))
```

output:
```shell
inputs: ['严蕊<s1>如梦令<s2>道是梨花不是。</s>道是杏花不是。</s>白白与红红,别是东风情味。</s>曾记。</s>曾记。</s>人在武陵微醉。', '<s1><s2>一句相思吟岁月</s>千杯美酒醉风情', '<s1><s2>几树梅花数竿竹</s>一潭秋水半屏山<s1><s2>未舍东江开口咏</s>且施妙手点睛来', '<s1><s2>一去二三里</s>烟村四五家']
outputs: ['<bos>盛世欣开新气象</s>春联喜绘大文章</s>春天铺锦笺,宏图更写好山山</s>新篇章</s>新篇章</s>神州高唱好年华</s>', '<bos>一曲琴音添雅韵</s>几回酒醉解愁思</s>', '<bos>三分天下隆中对</s>四面八方九派江山笔底留</s>', '<bos>春深花已老</s>夜静露方浓</s>']
inputs: ['<s1><s2>一句____月</s>千杯美酒__情', '<s1><s2>一去二三里</s>烟村__家</s>亭台__座</s>八__枝花']
outputs: ['<bos>一句佳诗吟盛月</s>千杯美酒祝春情</s>', '<bos>一去二三里</s>烟村百二家</s>亭台十二座</s>八里一枝花</s>']
