test's Introduction

Test

实体对齐

一、环境:java,jdk11 https://www.oracle.com/java/technologies/downloads/#java11-windows

二、code是加工脚本,按步骤执行即可 Excel是自己标的三元组,如果不支持.xlsx就用.xls

三、result是知识图谱,按说明文档操作

四、图数据库检索常用语句: 1、检索实体数据: # 查询'69-4 型潜水装具'的相关部件; MATCH p=(n:Nodes{name:'69-4 型潜水装具'})-[r:predicate]-(m:Nodes) where r.name = '部件' RETURN p

# 查询'69-4 型潜水装具'的所有的关联关系
MATCH p=(n:Nodes{name:'69-4 型潜水装具'})-[r:predicate]-(m:Nodes) 
RETURN p

2、创建索引 创建索引:CREATE INDEX ON :Nodes(name) 查询创建的索引 :schema 删除索引:DROP INDEX ON :Nodes(name)

3、显示全部节点(默认显示300个节点,若实体超过300,在设置中“Initial Node Display”设置显示数值)
match(n) return n
