中文电子病历命名实体识别

电子病历主要有入院记录、出院记录、病程记录、手术记录、护理记录、查房记 录等组成，除部分字段进行了前结构化，还有大量的字段没有进行结构化，以自由文本的方式进 行记录。该部分记录中含有大量的有用信息，是进行医疗大数据挖掘、临床辅助决策系统、AI 电子病历质控系统构建等的基础工作。命名实体的结果可以辅助人们识别并解释晦涩难懂的医疗术语，因此，电子病历命名实体识别有重大意义。

基于BERT+BiLSTM+CRF的中文电子病历命名实体识别

1 项目介绍

在本项目中将会介绍如何使用BERT+BiLSTM+CRF模型，实现对中文电子病历中病症、体征、疾病、身体部位等命名实体进行抽取。

1.1 项目背景

电子病历主要有入院记录、出院记录、病程记录、手术记录、护理记录、查房记 录等组成，除部分字段进行了前结构化，还有大量的字段没有进行结构化，以自由文本的方式进 行记录，比如主诉，现病史，既往史，查房记录，用药信息等。该部分记录中含有大量的有用信息，是进行医疗大数据挖掘、临床辅助决策系统、AI 电子病历质控系统构建等的基础工作。命名实体的结果可以辅助人们识别并解释晦涩难懂的医疗术语，方便人们了解和认识医学知识，因此，电子病历命名实体识别对医学研究、医疗诊断和患者都具有重要意义。

1.2 应用场景

医疗大数据挖掘构建医疗知识图谱临床辅助决策系统AI 电子病历质控系统构多病因联合分析

2 数据集

本项目开放了标注数据，data_origin.zip文件，数据集中包含一般情况、出院情况、病史特点、诊疗经过四种数据。以txtoriginal.txt结尾的文件是原始文本数据，直接是.txt结尾的文件是标注数据。

数据集包含的实体类型：

检查和检验-CHECK症状和体征-SIGNS疾病和诊断-DISEASE治疗-TREATMENT身体部位-BODY

数据集采用了BIO标注方式。BIO标注方式是一种常用的序列标注方法，用于对文本或语音等序列数据中的实体或事件进行标注。在BIO标注方式中，每个标记表示一个词或字符是否属于某个实体或事件，标记由三个部分组成：B（开始）、I（内部）和O（外部）。B表示该词或字符是某个实体或事件的开头（Beginning），I表示该词或字符属于某个实体或事件的中间部分（Inside），O表示该词或字符不属于任何实体或事件（Outside）。

对“全腹部压痛。”标注结果如下图所示：

其中B-BODY表示身体部位实体的开始，I-BODY表示身体部位实体的内部，O表示不属于任何实体部分。

2.1数据处理

通过构造TransferData对象，并调用transfer()方法将标注数据转换成BIO标注格式的数据，同时以7:3的比例划分训练集和验证集，再调用save_label_files()方法生成标签名，标签等映射文件，这些训练集（train.txt），验证集（eval.txt）和映射文件都保存在paddle_ner/data目录。data目录中的文件都会公开出来，没有其他需求可直接使用处理好的数据集，如果要修改数据集划分比例，请修改TransferData.divide_dataset()方法中的数据，并找到处理数据的cell执行即可。

在调用时注意相关文件路径。

3 模型选择

本项目使用BERT+BiLSTM+CRF实现命名实体识别

3.1 BERT模型

BERT（Bidirectional Encoder Representations from Transformers）是一种预训练语言模型，由Google在2018年提出。它的核心思想是在大规模文本数据上进行预训练，从而得到丰富的上下文相关的词向量表示。这些预训练的模型参数可以通过微调来适应各种自然语言处理任务，如文本分类、问答系统、命名实体识别等。

BERT的模型架构基于Transformer模型，它使用Transformer编码器来对输入的文本进行处理。其中，BERT模型分别在单词级别和句子级别上进行预训练，以获得上下文相关的词向量表示。

本实验利用BERT模型获取输入文本中每个词的Embedding向量，主要过程如上图所示。

数据处理的第一步就是将输入的文本进行分词，分词通常分为词级和字级分词，实验中选用的字级分词，即将句子中每一个字符分隔开，BERT模型比较大且复杂再加上使用的预训练模型，很容易学会字之间的关系。

经过分词处理之后，需要将其进行tokenize，此操作十分简单，BertTokenizer中通常会维护一个包含了大量字、词的词典，进行tokenize时，Tokenizer会根据字或词去查找其对应的ID，然后用ID来表达这个词，此操作的目的是将文本字符ID化，方便模型的处理。

然后只需要将tokenize的结果送入到BERT模型，经过模型的运算就能得到输入句子中每一个字符的词向量。通常词向量的维度不是一个固定值，可以根据具体情况进行设置。

3.2 BiLSTM+CRF

实验中使用BiLSTM网络实现对序列双向特征提取，使用CRF实现对标注序列解码。

BiLSTM模型能够对输入序列进行双向建模，即同时考虑从前往后和从后往前的上下文信息，并输出每个时刻的隐状态。这些隐状态可以被看作是对输入序列的抽象表示，用于捕捉序列的双向特征信息。

CRF是一种序列标注方法，它考虑了标签之间的依赖关系，通过在所有可能的标注序列中选择概率最大的标注序列来进行预测。在BiLSTM-CRF中，BiLSTM输出的隐状态序列通过一个线性层，CRF接受线形层的输出，对每个时刻预测对应的标签，同时考虑标签间的依赖关系，得到最终的标注序列。

3.3 模型整体结构

项目的主要任务是从大量的文本数据中提取出命名实体，模型上选用BERT+BiLSTM+CRF网络，首先使用数据集对BERT-wwm模型进行微调，用微调后的BERT模型对输入做Embedding来获得句向量，最后使用双向长短期记忆网络（BiLSTM）和条件随机场（CRF）实现实体识别。

4.8 自定义模型

4.8.1 超参数

bert:预训练BERT模型lstm_hidden_size:LSTM隐藏层大小，默认512num_class:标签的数量，默认11+3 11个标注标签，3个tokenizer中需要的标签crf_lr:CRF层的学习率

4.8.2 返回值

logits:全连接层的输出，用于计算lossseq_len:输入句子的实际长度，不包括paddingprediction:预测结果

4.8.3 网络介绍

bert为预训练模型，参与模型训练进行微调，对输入数据做embedding，输出句向量BiLSTM主要是用来进行特征提取全连接层用来将BiLSTM的输出映射到分类的维度，没有激活函数LinearChainCrf层寻找一条概率最大的标注路径ViterbiDecoder对CRF计算结果进行解码，得到标注信息In [11]

4.9 模型构建

使用BertModel.from_pretrained(“bert-wwm-ext-chinese”)加载预训练BERT模型,该模型是BERT-wwm的一个升级版，相比于BERT-wwm的改进是增加了训练数据集同时也增加了训练步数。使用LinearChainCrfLoss损失函数,专用于计算CRF的loss使用AdamW优化器学习率预热scheduler,预热步数设置为300步，预热起始值不能从0 开始，否则收敛将模型封装成paddle.Model方便使用高级apiIn [12]

4.10 构建训练函数

使用EarlyStopping回调回调，在监控指标不发生变化4个epoch后自动停止使用ReduceLROnPlateau回调，当模型趋于收敛时降低学习率使用VisualDL回调，记录训练过程中的评估指标因使用了EarlyStopping,可将总的epoch数设置一个大一点的值In [13]

5 训练过程及结果

EarlyStoping的monitor先后分别使用了loss和precision作为监控指标,耐心值设置为4 epoch，loos作为监控指标13 epoch自动停止,第9 eopch取得最好的模型；precision作为监控指标17 epoch自动停止，第13 epoch取得最好的模型。

monitor：loss 蓝色

monitor：precision 绿色

5.1 结果分析

训练集precision一般在95%-96%，随着epoch不断增加，precision也能达到97%以上，但是对比发现验证集准确率并没有上去，估计是有点过拟合，那部分模型直接丢掉，recall和F1-score都在96%-97%之间。

验证集precision一般在94%-95%，recall在95%-96%之间，F1-score在94%-95%之间

6 模型转换

训练完成后保存的模型只是模型的参数，需要将动态的模型保存为静态模型，才能用于部署。

6.1 先加载保存的最好的模型

In [15]

# 加载最好的动态模型,模型文件已经删除，需要重新训练lstm_hidden_size = 512 # 这个参数在train()函数中写死了，训练时可以根据需求调model_name="best_model.pdparams"# 加载映射文件with open(os.path.join(project_root_dir, "data/id2labels.json"), "r", encoding="utf-8") as f:    id2labels = json.load(f)# 加载bertbert = BertModel.from_pretrained("bert-wwm-ext-chinese")# 加载动态模型model = NERModel(bert, lstm_hidden_size=lstm_hidden_size, num_class=len(id2labels))model_dict = paddle.load(path = os.path.join(project_root_dir, "checkpoint", model_name))model.load_dict(model_dict)

6.2 通过paddle.jit.save方法把动态的模型转换为静态模型，并保存，需要事先定义好输入句柄

In [ ]

# 将模型转换为静态图，并保存input_spec = [    InputSpec([None, None], dtype="int64", name="input_ids"),    InputSpec([None, None], dtype="int64", name="token_type_ids"),    InputSpec([None], dtype="int64", name="seq_len")]# 保存为静态模型paddle.jit.save(model,input_spec=input_spec, path=os.path.join(project_root_dir, "static_model","best_model"))

6.3 通过paddle.jit.load方法可直接加载静态模型

In [ ]

# 加载保存的静态模型model=paddle.jit.load("paddle_ner/static_model/static_model")

8 模型部署

Paddle Inference 是飞桨的原生推理库， 作用于服务器端和云端，提供高性能的推理能力。

Paddle Inference 功能特性丰富，性能优异，针对不同平台不同的应用场景进行了深度的适配优化，做到高吞吐、低时延，保证了飞桨模型在服务器端即训即用，快速部署。

若要在服务器部署，请下载static_model文件夹下的静态模型文件，部署模型代码请参考deployment_model.py文件，涉及的核心代码是加载模型，处理数据，喂入数据，解析预测结果

受bert的影响，代码中设置了推理最大长度限制为512，超长会被截断

创建一个Config对象，将模型文件地址作为参数传入，然后再根据配置加载模型

config = Config("checkpoint/static_model.pdmodel", "checkpoint/static_model.pdiparams")  # 通过模型和参数文件路径加载predictor = paddle_infer.create_predictor(config)  # 根据预测配置创建预测引擎predictor

先通过获取输入Tensor的名称，再根据名称获取到输入Tensor的句柄

# 获取输入变量句柄input_names = predictor.get_input_names()inputs_ids_handle = predictor.get_input_handle(input_names[0])  # [batch_size,max_seq_len]token_type_ids_handel = predictor.get_input_handle(input_names[1])  # [batch_size,max_seq_len]seq_len_handel = predictor.get_input_handle(input_names[2])  # [seq_len]

通过process_text方法将文本处理成输入特征

input_ids, token_type_ids, seq_len = process_text(text_list)

在predict方法中，首先要将输入特征喂入模型，然后进行推理，再获取推理结果，最后解析推理结果

def predict(text=None, input_ids=None, token_type_ids=None, seq_len=None):    """    预测函数    :param text:    :param input_ids:    :param token_type_ids:    :param seq_len:    :return:    """    assert text is not None and len(        text) > 0 and input_ids is not None and token_type_ids is not None and seq_len is not None, "参数有误"    # 设置输入    inputs_ids_handle.copy_from_cpu(input_ids)    token_type_ids_handel.copy_from_cpu(token_type_ids)    seq_len_handel.copy_from_cpu(seq_len)    # 推理    predictor.run()    # 获取输出    output_names = predictor.get_output_names()    prediction_handel = predictor.get_output_handle(output_names[-1])    prediction = prediction_handel.copy_to_cpu()    # label_id转 label    prediction = np.reshape(prediction, [-1])    pred_labels = []    for idx in prediction:        label = id2labels[str(idx)]        pred_labels.append(label)    # 解析抽取结果,解析时排除[CLS] [SEP]    return parse_pred_labels_to_entity(text, pred_labels[1:-2])

部署模型推理示例：由于设置了循环，当输入q!时自动退出
