structure_converter.py：抽象基类用于定义结构转换器的接口
class StructureConverter(object): def structure_to_input(self, input_dict: dict, prompt_part_only: bool = False) -> str: raise NotImplementedError() def output_to_structure(self, input_dict: dict, output_str: str): raise NotImplementedError() @staticmethod def to_function_head(s,input=''): return f'def {s}({input}):' @staticmethod def to_function_name(s): s = s.replace(".", "").replace(",", "") # remove DT tok = s.lower().split() tok = [x for x in tok if x not in ['the', 'a', 'an']] return '_'.join(tok) @staticmethod def list_to_str(l): # remove \n l = [x.replace("\n", " ") if x != '\n' else '' for x in l] l = '\n'.join(l) return l
这是一个名为 StructureConverter 的Python类，它是一个抽象基类（Abstract Base Class）用于定义结构转换器的接口。这个类包含以下几个方法和静态方法：
structure_to_input(self, input_dict: dict, prompt_part_only: bool = False) -> str：这是一个抽象方法，用于将输入数据结构转换为文本输入。派生类应该实现这个方法来定义特定任务的输入结构到文本输入的转换逻辑。output_to_structure(self, input_dict: dict, output_str: str)：这是另一个抽象方法，用于将输出文本转换回数据结构。与structure_to_input类似，它的实现应该由派生类来完成。to_function_head(s, input='')：这是一个静态方法，用于生成Python函数的头部，其中s是函数的名称，input是函数的参数。它返回一个字符串，表示函数定义。to_function_name(s)：这是另一个静态方法，用于生成合法的Python函数名。给定一个字符串s，它将字符串处理为合适的Python函数名称格式，删除标点符号并将单词连接成下划线分隔的格式。list_to_str(l)：这也是一个静态方法，用于将字符串列表l转换为一个字符串，并处理换行符\n。它将列表中的每个字符串连接成一个字符串，换行符替换为空格，返回一个多行的字符串。
StructureConverter 类本身是一个抽象基类，无法直接实例化。相反，它提供了接口和一些实用方法，供派生类实现和使用，以定义特定任务的结构转换逻辑。这个类可以作为其他具体结构转换器类的基类，以提供通用的接口和方法。

这些函数是一组用于字符串处理、列表操作和代码编译的实用工具函数。以下是这些函数的简要描述：
match_sublist(the_list, to_match)：查找列表the_list中所有与to_match匹配的子列表，并返回它们的索引范围。例如，the_list是[1, 2, 3, 4, 5, 6, 1, 2, 4, 5]，to_match是[1, 2]，则返回[(0, 1), (6, 7)]，表示匹配的子列表的起始和结束索引。check_overlap(x, y)：检查两个索引范围x和y是否有重叠，如果有重叠返回True，否则返回False。get_index_tuple(matched: Tuple[int, int])：将匹配的索引范围matched转换为一个元组，包含范围内的所有索引。span_to_token(text, span_to_token_strategy='space')：将文本text按照指定策略span_to_token_strategy分割为单词或字符列表。默认使用空格分割策略，可以选择'list'策略以将文本拆分为字符列表。to_camel_case(title: str)：将一个标题字符串title转换为驼峰命名法格式。例如，将 “travel to the theme park” 转换为 “TravelToThemePark”。to_snake_case(name)：将字符串name转换为蛇形命名法（snake_case）格式，用下划线分隔单词。from_snake_to_normal_str(snake_str: str)：将蛇形命名法字符串snake_str转换为普通字符串，通过删除下划线并用空格分隔单词。compile_code_get_object(py_code_str: str)：编译给定的 Python 代码字符串py_code_str并返回该代码中包含的类的对象。这个函数首先编译代码，然后实例化类并返回其对象。
这些函数提供了一些用于文本处理、字符串格式转换和代码执行的常见功能，可在不同的上下文中使用。

这段代码是一个命令行工具，用于评估NLP任务的结果与金标准之间的差异。具体来说，它有以下功能：
- 从命令行参数中获取要评估的模型输出（predicted results）和金标准数据（golden dataset）。
- 支持对不同任务（entity、relation、event）的评估。
- 支持设置不同的评估模式，包括"set"、"normal"和"multimatch"等。
- 可以在评估结果中输出更多信息，以便进行更详细的分析。
- 可以将评估结果写入文件，保存到预测结果文件夹中。
主要的功能包括：
- 读取模型的预测结果和金标准数据文件。
- 对模型输出和金标准数据进行解析，提取相应任务（entity、relation、event）的信息。
- 调用评估工具类（
EntityScorer、RelationScorer、EventScorer）对预测结果和金标准数据进行评估。 - 计算各项评估指标，包括精确度、召回率、F1分数等，并将结果输出到控制台或保存到文件中。
- 如果设置了"case"选项，还会输出详细的案例分析信息，包括模型的预测结果和金标准数据。
该工具主要用于评估NLP任务的结果，帮助研究人员和从业者了解模型的性能和改进方向。

这段代码主要用于评估NLP任务中的模型预测结果，并将评估后的结果存储到指定的输出文件中。以下是其主要功能：
- 从命令行参数中读取各种输入文件和配置参数，包括原始输出文件（
raw_output_file）、输出文件（output_file）、数据源文件（src_file）、任务类型（job_type）、模式配置路径（schema_path）、映射配置路径（map_config_path）、预测键名（pred_key）等。 - 通过
Converter工厂类创建适当的转换器（如NER或RE），用于将原始模型预测结果转换为结构化的评估结果。 - 遍历数据源文件中的每个示例，对每个示例的原始模型预测结果进行结构化转换和评估。
- 计算各种评估指标，包括识别标签不合法（
Invalid-Label）、文本跨度不合法（Invalid-Text-Span）、标签关联不合法（Invalid-Label-asoc）、文本跨度关联不合法（Invalid-Text-Span-asoc）等。 - 统计不合法的预测结果数量，包括不合法的标签、文本跨度和它们的关联。
- 最后，将评估后的结果以JSON格式保存到输出文件中，并在控制台输出统计信息。

这段代码定义了一个评估（scoring）模块，用于计算不同任务（如实体识别、关系抽取、事件抽取）的评估指标。下面是代码的主要组成部分：
Metric类：这是一个通用的评估指标类，用于计算真阳性（true positives，tp）、金标样本数（gold_num）、预测样本数（pred_num）以及相关的评估指标，如精确度（P）、召回率（R）和 F1 分数。safe_div方法用于进行除法计算，以避免除以零的情况。compute_f1方法计算 F1 分数。count_instance方法用于计算指标的真阳性、金标样本数和预测样本数。RecordMetric类：这是继承自Metric类的一个子类，用于处理不考虑不同角色之间的顺序的任务（例如事件论元抽取）。它包括了一个额外的is_equal方法，用于判断金标和预测是否相等。OrderedRecordMetric类：这是继承自RecordMetric类的子类，用于处理考虑不同角色之间的顺序的任务（例如关系抽取）。它重写了is_equal方法，以考虑不同角色之间的顺序。Scorer类：这是一个基本的评估类，定义了三个静态方法load_gold_list、load_pred_list和eval_instance_list，分别用于加载金标样本、预测样本，以及计算评估指标。子类可以继承这个类并实现这些方法来适应不同的任务。EntityScorer、RelationScorer和EventScorer类：这些类分别用于实体识别、关系抽取和事件抽取任务。它们通过继承Scorer类，实现了加载金标样本和预测样本的方法，以及计算相应任务的评估指标的方法。
这段代码的目的是提供一个通用的评估框架，使用户能够方便地计算不同任务的评估指标，例如 F1 分数。根据任务的特点，可以选择适当的评估类来加载数据并计算指标。

这段代码的主要功能是生成提示文本（prompt）用于模型的训练。以下是代码的主要步骤和功能：
- 代码通过命令行参数接受输入文件的路径、输出文件的路径、生成的提示文本的样本数（
n_examples）、种子值（seed）、以及其他必要参数。 - 从输入文件中读取数据，数据以JSON格式存储。可以选择从中随机采样一定数量的样本，也可以使用所有的样本。
- 随机打乱数据的顺序。
- 创建一个空的提示文本字符串。
- 对每个样本，将样本的
reference_output字段添加到提示文本字符串中，同时在每个样本之间添加特定标记（END）以分隔不同的样本。 - 将生成的提示文本字符串写入输出文件中。
- 输出提示文本的保存路径，以便用户查看。
这段代码通常用于生成用于训练NLP模型的提示文本，可以从数据中随机选择一些样本，并按一定格式组织成提示文本，以供后续模型训练使用。

这段代码的主要功能是将给定的数据转换成适用于模型训练的任务文件。以下是代码的主要步骤和功能：
- 代码通过命令行参数接受输入文件的路径、输出文件的路径、任务类型（
job_type）、模式配置文件的路径（schema_path）、映射配置文件的路径（map_config_path），以及其他必要参数。 - 从输入文件中读取数据，数据通常以DataFrame格式存储。
- 利用
ConverterFactory从给定的任务类型和配置文件加载适当的转换器（例如，NER或RE转换器）。 - 对于数据中的每一行，调用转换器的
structure_to_input方法将原始数据转换为适用于模型训练的输入。此外，还提取一些其他字段，如索引、输入提示等，用于创建任务文件的元信息。 - 如果数据的转换成功，将转换后的数据添加到结果列表中。
- 最后，计算成功转换的数据比例，并将结果保存为JSON格式的任务文件，以供后续模型训练使用。
总的来说，这段代码用于将原始数据转换为可用于不同NLP任务（如NER、RE等）的任务文件格式，以便模型能够理解和学习这些任务。生成的任务文件包含了输入、输出和其他元信息，以便于后续的训练和评估。
utils
file_utils.py：加载数据和配置信息，以便进行任务的转换和生成
import yaml import pandas as pd def load_schema(schema_path): with open(schema_path,encoding='utf8') as fin: entity_line = fin.readline().strip() relation_line = fin.readline().strip() spot_asoc_line = fin.readline().strip() return {'entity_schema': eval(entity_line), 'relation_schema': eval(relation_line), 'spot_asoc_schema': eval(spot_asoc_line)} def load_yaml(yaml_path): with open(yaml_path,'r') as fin: map_config = yaml.load(fin.read(), Loader=yaml.FullLoader) return map_config def read_data(inpath): if "json" in inpath: data = pd.read_json(inpath, orient='records', lines=True) else: raise ValueError(f"Unknown input format: {inpath}") return data
这段代码是一组用于加载数据和配置文件的辅助函数，包括：
load_schema(schema_path)函数用于加载给定路径的模式（schema）文件。该文件通常包含了实体、关系和关联标签的信息。函数读取文件的前三行，分别包含了实体模式、关系模式和关联标签模式的定义，然后返回这些模式的字典。load_yaml(yaml_path)函数用于加载给定路径的YAML格式配置文件。它打开指定路径的文件，使用PyYAML库加载文件内容，并返回加载后的配置字典。read_data(inpath)函数用于加载数据文件，支持JSON格式的数据文件。它检查文件类型，如果文件类型为JSON，它使用Pandas库的pd.read_json函数加载文件内容为DataFrame，并以行的方式解释为记录。函数返回加载后的数据作为DataFrame。
这些函数用于在主要代码中加载数据和配置信息，以便进行任务的转换和生成。例如，load_schema函数加载了任务所需的模式信息，而load_yaml函数加载了映射配置文件。 read_data 函数用于加载任务的输入数据。这些辅助函数有助于使主要代码更模块化和易于维护。

这段代码定义了一个名为 RecordSchema 的类，该类用于管理任务的记录模式（schema）。记录模式通常包括实体类型（type）、关系角色（role）和类型-角色字典（type_role_dict）。
__init__方法初始化RecordSchema类的实例，需要传入类型列表（type_list）、角色列表（role_list）和类型-角色字典（type_role_dict）。read_from_file方法从文件中读取记录模式的定义。它读取文件的前三行，分别包含类型列表、角色列表和类型-角色字典的定义，并使用这些信息创建RecordSchema的实例。write_to_file方法将记录模式的定义写入文件。它将类型列表、角色列表和类型-角色字典的信息写入文件的三行中。
此外，代码还定义了一个名为 merge_schema 的函数，用于合并多个记录模式。它接受一个记录模式列表 schema_list，并合并这些记录模式的类型、角色和类型-角色字典信息，最终返回一个合并后的 RecordSchema 实例。
这些工具函数和类用于管理任务的记录模式信息，以便在任务处理过程中进行合并和存储。
