基于ChatGPT的医学实体链接方法研究（英文中文双语版优质文档）

In recent years, with the continuous accumulation of medical

data and the rapid development of medical artificial

intelligence, medical entity linking technology has also been

more and more widely used. Medical entity linking refers to

linking entities in medical texts (such as diseases, drugs,

symptoms, etc.) with entities in the medical knowledge graph,

so as to realize automatic extraction and semantic analysis of

medical knowledge. In recent years, ChatGPT-based medical

entity linking methods have been widely studied and applied

in the medical field. This paper will introduce and analyze the

research progress in this field in detail.

1. Overview of ChatGPT-based medical entity linking method

ChatGPT is a Transformer-based natural language processing

technology, which can automatically learn the characteristics

of the text by learning a large amount of text, and generate

new text that conforms to grammatical and semantic rules.

The medical entity linking method based on ChatGPT refers to

using the ability of ChatGPT to carry out semantic analysis on

medical texts, automatically identify entities in the text, and

map them to corresponding entities in the medical knowledge

map, so as to realize the automatic extraction and extraction

of medical knowledge. Semantic Analysis.

In the ChatGPT-based medical entity linking method, it is

mainly divided into the following steps:

1. Data preprocessing

First of all, medical text needs to be preprocessed, including

word segmentation, part-of-speech tagging, entity recognition

and other operations. These operations can help ChatGPT

better understand the semantics of medical texts.

2. Build a knowledge map

Constructing medical knowledge graph is the basis of

ChatGPT-based medical entity linking method. The medical

knowledge graph is composed of a large number of medical

entities and the relationship between entities, which can help

ChatGPT better understand the semantic relationship

between medical entities.

3. Entity identification and linking

Through ChatGPT technology, medical texts are semantically

analyzed, entities in the text are automatically identified, and

they are mapped to corresponding entities in the medical

knowledge graph. This step needs to use the medical entity

linking algorithm to match the entities in the medical text with

the entities in the medical knowledge graph, so as to realize

the linking of entities.

4. Knowledge fusion and reasoning

Through ChatGPT technology, the existing entities and

relationships in the medical knowledge map are learned, and

knowledge fusion and reasoning are performed, so as to

realize the prediction and reasoning of entities and

relationships in new texts. This step can help ChatGPT better

understand the semantic relationship between medical

entities, so as to realize the automatic extraction and semantic

analysis of medical knowledge.

2. Advantages and challenges of ChatGPT-based medical

entity linking method

Compared with traditional methods, ChatGPT-based medical

entity linking method has the following advantages:

1. Better semantic understanding

ChatGPT can automatically learn the semantic features of the

text by learning a large amount of text, so as to better

understand the semantics in medical texts and improve the

accuracy and reliability of medical entity links.

2. Better scalability

The medical knowledge graph is a huge knowledge base, and

new entities and relationships are constantly added. The

traditional method needs to manually update the knowledge

base, which is very time-consuming and labor-intensive. The

method based on ChatGPT can automatically expand the

knowledge base by learning and training new data, so it has

better scalability.

But the ChatGPT-based medical entity linking method also

faces some challenges:

1. Limitation of data volume

ChatGPT requires a large amount of training data to better

learn the semantic features of the text, but the amount of

data in the medical field is relatively small, so the training of

the ChatGPT model will be limited.

2. Imperfect knowledge base

The construction of medical knowledge graphs requires a lot

of professional knowledge and experience, and the coverage

and depth of current medical knowledge graphs are still

insufficient, which limits the application range and accuracy of

ChatGPT-based medical entity linking methods.

3. Application of ChatGPT-based medical entity linking

method

The medical entity linking method based on ChatGPT has a

wide range of applications in the medical field, mainly

including the following aspects:

1. Medical Text Classification and Labeling

ChatGPT can classify and label medical texts, and mark

entities, symptoms, treatment plans, etc. in the text, so as to

realize the automatic extraction and classification of medical

knowledge.

2. Construction of medical knowledge map

The ChatGPT-based method can automatically extract entities

and relations from medical texts and map them to the medical

knowledge graph, thereby automatically constructing and

updating the medical knowledge graph.

3. Medical diagnosis and treatment assistance

The ChatGPT-based medical entity linking method can

automatically link the entities and relationships in medical

texts to the medical knowledge graph, thereby helping

doctors diagnose and formulate treatment plans more quickly

and accurately. For example, based on the patient's symptoms,

signs, medical history and other information, relevant entities

and relationships can be automatically extracted, linked to the

medical knowledge graph, and then corresponding diagnosis

and treatment suggestions can be given.

4. Medical research and new drug development

The medical entity linking method based on ChatGPT can

automatically extract entities and relationships from a large

amount of medical literature, help researchers better

understand and analyze medical knowledge, and accelerate

the process of new drug development.

In general, the ChatGPT-based medical entity linking method

has broad application prospects, which can help the medical

community to better utilize and understand medical

knowledge, and improve the efficiency and accuracy of

medical research and clinical practice.

近年来，随着医疗数据的不断积累和医疗人工智能的快速发展，医学实体链接技术也得到了越来越广泛的应用。医学实体链接是指将医学文本中的实体（例如疾病、药品、症状等）与医学知识图谱中的实体进行链接，从而实现对医学知识的自动化提取和语义分析。近年来，基于ChatGPT的医学实体链接方法在医疗领域得到了广泛的研究和应用，本文将对这一领域的研究进展进行详细介绍和分析。

一、基于ChatGPT的医学实体链接方法概述

ChatGPT是一种基于Transformer的自然语言处理技术，它可以通过对大量文本的学习，自动学习文本的特征，并生成符合语法和语义规则的新文本。基于ChatGPT的医学实体链接方法是指利用ChatGPT的能力，对医学文本进行语义分析，自动识别文本中的实体，并将其映射到医学知识图谱中的相应实体，从而实现对医学知识的自动化提取和语义分析。

在基于ChatGPT的医学实体链接方法中，主要分为以下几个步骤：
