📘 概述

ReasoningAnswerExtractionQwenMathEvalGenerator 该算子用于从数学问题回答中提取规范化答案表达式，进行字符串清洗、单位处理和格式标准化。

__init__函数

@OPERATOR_REGISTRY.register()
class ReasoningAnswerExtractionQwenMathEvalGenerator(OperatorABC):
    """
    A class to handle the process of extracting answers from a dataset.
    """

    def __init__(self, dataset_name:str = None):

init参数说明

参数名	类型	默认值	说明
dataset_name	str	None	数据集名称，用于特定数据集的答案提取逻辑。

run函数

def run(self, storage: DataFlowStorage, response_key:str = "pseudo_correct_solution_example", extraction_key:str = "extraction")

执行算子主逻辑，从存储中读取包含待提取答案的 DataFrame，提取规范化答案，并将结果写回存储。

参数

名称	类型	默认值	说明
storage	DataFlowStorage	必需	数据流存储实例，负责读取与写入数据。
response_key	str	"pseudo_correct_solution_example"	输入列名，对应包含待提取答案的原始文本字段。
extraction_key	str	"extraction"	输出列名，对应提取并规范化后的答案字段。

🧠 示例用法

from dataflow.operators.reasoning import ReasoningAnswerExtractionQwenMathEvalGenerator
from dataflow.utils.storage import FileStorage
from dataflow.core import LLMServingABC

class ReasoningAnswerExtractionQwenMathEvalGeneratorTest():
    def __init__(self, llm_serving: LLMServingABC = None):
        
        self.storage = FileStorage(
            first_entry_file_name="example.json",
            cache_path="./cache_local",
            file_name_prefix="dataflow_cache_step",
            cache_type="jsonl",
        )
        
        self.operator = ReasoningAnswerExtractionQwenMathEvalGenerator()
        
    def forward(self):
        self.operator.run(
            storage = self.storage.step(),
            input_key = "pseudo_correct_solution_example",
            output_key = "extraction"
        )

if __name__ == "__main__":
    pl = ReasoningAnswerExtractionQwenMathEvalGeneratorTest()
    pl.forward()

🧾 默认输出格式（Output Format）

字段	类型	说明
(原始字段)	-	输入数据中的所有原始字段将被保留。
extraction	str	提取并规范化后的数学答案表达式。

示例输入：

{
"pseudo_correct_solution_example": "The circumference of the circle is 2 * pi * 5, which is approximately 31.4. Therefore, the answer is \\boxed{31.4}."
}

示例输出：

{
"pseudo_correct_solution_example": "The circumference of the circle is 2 * pi * 5, which is approximately 31.4. Therefore, the answer is \\boxed{31.4}.",
"extraction": "31.4"
}
