使用d3.js可视化知识图谱

=============================

data目录

  • bg.jpg可视化背景图片数据
  • CircularPartition.json节点圆形分区图工具栏需要加载的数据
  • test.json可视化需要展示的数据格式

images

  • 此目录存储节点属性图片数据

js

  • d3.js version-3.2.8

src

  • JS以及其它HTML等源码

index.html

  • 知识图谱可视化入口文件

访问地址

启动部署文件

  • ./knowledge-graph-web

CSV文件导入接口

//默认标签‘Person’,可自定义
{
    "label": "Person"
}
  • CSV文件分为节点和关系分别存放在不同文件,文件位置:knowledge-graph\neo-import-csv
  • 修改文件内容之后直接调用接口即可

CSV-USER-DEFINED文件导入接口

切换到QA模式

基于图谱的问答模式

1、QA检索

  • 检索字符串以‘=QA’结尾,例如:傻宝旗舰店售卖温控器吗=QA

优化QA查询效果可在‘dic\dic-cfg\user-dic\user_defined.dic’目录添加自定义词

  • 未添加自定义词:[傻, 宝, 旗舰店, 售卖, 温控器, 吗]
  • 添加之后:[傻宝旗舰店, 售卖, 温控器, 吗] 图

2、多实体对检索

图

清除图库数据

MATCH (n) 
OPTIONAL MATCH (n)-[r]->() DELETE n,r

NEO4J启动脚本

  • start.bat
bin\neo4j.bat console
