前言

Python实验课时，老师提到用知识图谱构建红楼梦的人物关系图，所以课后根据视频和博客的学习，初尝试用neo4j进行构建，也在学习如何用Python直接进行手撕关系图并可视化，但是目前效果不佳，后续构建好继续分享在专栏。

neo4j基础知识

neo4j.com进行数据库下载安装

使用命令行输入

neo4j.bat console

 找到localhost:7474，复制到浏览器进行登录，初始用户名和密码均为neo4j

其实在最顶端的窗口可以直接进行图谱的搭建，但由于本文是实现 Python进行构建，所以不在此进行赘述。

Pycharm及代码实现

 py2neo

neo4j提供python接口，可以使用py2neo库通过python操作neo4j数据库，py2neo安装较为简单，仅需要使用pip install方式进行安装。使用如下命令：

pip install py2neo

 安装完后进行测试：

from py2neo import Graph, Node, Relationship

def connect_database(username, password, dbname):
    graph_db = Graph("http://localhost:7474", name=dbname, auth=(username, password))
    return graph_db
    
if __name__ == '__main__':
    graph = connect_database("neo4j", "password", "neo4j")

 数据集获取

代码介绍

由于大部分代码都进行了注释，所以大家可以直接拷贝代码进行学习，在此不赘述代码作用

import csv
from py2neo import Graph, Node, Relationship

# 创建与 Neo4j 数据库的连接
g = Graph('http://localhost:7474', user='neo4j', password='neo4j123..', name="neo4j")

# 打开 CSV 文件
with open('HongLou.csv', 'r', encoding='utf-8') as f:
    # 创建一个 CSV 读取器
    reader = csv.reader(f)
    # 遍历 CSV 文件中的每一行
    for item in reader:
        # 跳过标题行，因为从第二行开始才是人物信息
        if reader.line_num == 1:
            continue
        # 打印当前行号和内容
        print("当前行数：", reader.line_num, "当前内容：", item)

        # 使用 CSV 中的值创建起始节点和结束节点，节点标签为 'Person'，名称属性来自 CSV
        start_node = Node("Person", name=item[0])
        end_node = Node("Person", name=item[1])

        # 使用 CSV 中的值创建起始节点和结束节点之间的关系，关系类型为 CSV 中的值
        relation = Relationship(start_node, item[3], end_node)

        # 将起始节点和结束节点合并到图中，使用节点标签 'Person' 和名称属性进行匹配
        g.merge(start_node, "Person", "name")
        g.merge(end_node, "Person", "name")
        # 将关系合并到图中，使用节点标签 'Person' 和名称属性进行匹配
        g.merge(relation, "Person", "name")

 最后回到我们的neo4j中就能看到关系图谱啦
