使用import csv檔案方式建立知識圖譜

1.檢視是否有import資料夾

2.在import資料夾裡放入csv檔案

3.實用Cpyher語句，匯入資料

LOAD CSV WITH HEADERS FROM "file:///julian_person.csv" AS line MERGE (p:Person {id:line.p_id, name:line.name, introduction:line.introduction})

LOAD CSV WITH HEADERS FROM "file:///julian_company.csv" AS line MERGE (c:BC_Company {id:line.c_id, name:line.name, tag:line.tag, introduction:line.introduction})

LOAD CSV WITH HEADERS FROM "file:///julian_p_c_rel.csv" AS line

match (from:Person{id:line.p_id}),(to:Company{id:line.c_id})

merge (from)-[r:member{p_id:line.p_id,c_id:line.c_id}]->(to)

關於亂碼問題：

load csv 中文編碼亂碼,  必須確保csv檔案的編碼格式：UTF8 無BOM格式

再增加一些關係節點

Cpyher語句，匯入資料:

LOAD CSV WITH HEADERS FROM "file:///chain_block_kg.csv" AS line MERGE (p:BC_Konwledge {id:line.id, name:line.name})

LOAD CSV WITH HEADERS FROM "file:///kg_rel.csv" AS line

match (from:BC_Knowledge{id:line.c_id}),(to:BC_Knowledge{id:line.id})

merge (from)-[r:isInculdeOf]->(to)

LOAD CSV WITH HEADERS FROM "file:///julian_c_kg_rel.csv" AS line

match (from:BC_Company{id:line.c_id}),(to:BC_Knowledge{id:line.kg_id})

merge (from)-[r:companyTagIs]->(to)

LOAD CSV WITH HEADERS FROM "file:///tokenview_coin.csv" AS line MERGE (p:Coin {id:line.id, name:line.name, Alias:line.alia, introduction:line.summaryCn})
