eaas 0.1.4

Evaluation as a Service for Natural Language Processing

EaaS_API

Documentation

Setup can be found here. Documentation at https://expressai.github.io/EaaS_API/

Usage

To install the API, simply run

pip install eaas_api

To use the API, run the following.

from eaas_api import Client
client = Client()
client.load_config("config.json")  # you can change the settings for each metric in `config.json`

# To see supported metrics
print(client.metrics)

To use this API for scoring, you need to format your input as list of dictionary. Each dictionary consists of src (string, optional), refs (list of string, optional) and hypo (string, required). src and refs are optional based on the metrics you want to use. Please do not conduct any preprocessing on src, refs or hypo, we expect normal-cased detokenized texts. All preprocessing steps are taken by the metrics. Below is a simple example.

inputs = [{"src": "This is the source.", 
           "refs": ["This is the reference one.", "This is the reference two."],
           "hypo": "This is the generated hypothesis."}]
metrics = ["bleu", "chrf"] # Can be None for simplicity if you consider using all metrics

score_dic = client.score(inputs, metrics) # inputs is a list of Dict, metrics is metric list

The output is like

{
  'bleu': [32.46679154750991],  # Sample-level scores. A list of scores one for each sample.
  'corpus_bleu': 32.46679154750991, # Corpus-level score.
  'chrf': [38.56890099861521],
  'corpus_chrf': 38.56890099861521
}

Short-term TODO

• Write config.json, add backend support.

Long-term TODO

• 完善功能
• 只给aws的ip (起一个api.eaas类似这样的域名)，aws后期二次转发到cmu服务器
• 打包成package
• metric corpus-level指标计算; BLEU corpus-level的计算检查（是否其他metric也有类似的）；我们可能要设计下返回结果的json格式
• 我们弄个文档，总结每个指标的默认预处理方法，超参数使用，考虑是否预留个接口给用户设置
• Confidence interval计算功能
• Fine-grained analysis功能
• 优化API访问效率
