wikidata数据dump到arangodb的方法

第一步：下载wikidata全量数据压缩包 第二步：使用python脚本提取实体到entity.json，提取属性信息到statement.json 第三步：通过arangodb导入json的命令将数据导入到库中

arangoimport --threads 4 --server.endpoint tcp://127.0.0.1:8529 --server.username root --server.password root --server.database kgms --file "\mnt\entity.json" --type json --collection "entity" --batch-size 33554432 arangoimport --threads 4 --server.endpoint tcp://127.0.0.1:8529 --server.username root --server.password root --server.database kgms --file "\mnt\link.json" --type json --collection "link" --batch-size 33554432

arangodb初始化库方法

第一步：创建数据库 第二部：创建数据表 第三步：创建图 第四步：创建视图

需求：批量筛选实体列表导出属性到excel

  1. 筛选实体 方法一：通过关键词检索entity表 方法二：通过属性和值筛选link表 结果，返回实体id数组

[ "Q22099965","Q21040218"]

  1. 配置属性 通过多个实体id获取属性并集，勾选需要导出的属性
RETURN UNIQUE(FOR l IN link
FILTER l['_from'] IN ["entity/Q22099965","entity/Q21040218"]
RETURN l.mainsnak.property)

[ "P31", "P569", "P106", "P21", "P39", "P69", "P734", "P102", "P3373", "P27", "P19" ]

  1. 转换到excel
FOR l IN link
FILTER l['_from'] IN ["entity/Q22099965","entity/Q21040218"]
FILTER l.mainsnak.property IN [
    "P31",
    "P569",
    "P106",
    "P21",
    "P39",
    "P69",
    "P734",
    "P102",
    "P3373",
    "P27",
    "P19"
]

COLLECT id=l['_from']  INTO groups

LET gs = (
    FOR g IN groups
    LET value = g.l.mainsnak.datavalue.type=='wikibase-entityid' ? g.l.mainsnak.datavalue.value.id : (g.l.mainsnak.datavalue.type=='time' ? g.l.mainsnak.datavalue.value.time : g.l.mainsnak.datavalue.value)
    RETURN {[g.l.mainsnak.property]: value}
)


RETURN MERGE(gs)

总结

let items = ["entity/Q22099965","entity/Q21040218","entity/Q21040220"]

let properties = (RETURN UNIQUE(FOR l IN link FILTER l['_from'] IN items RETURN {id:l.mainsnak.property, label:DOCUMENT(CONCAT('entity/',l.mainsnak.property))['labels']['zh']['value']}))[0]

FOR i in items
let values = (FOR p in properties LET value = (FOR l IN link FILTER l['_from'] == i AND l.mainsnak.property==p.id RETURN l.mainsnak.datavalue) RETURN value[0]['type']=='wikibase-entityid'? TO_ARRAY(DOCUMENT(CONCAT('entity/',value[0]['value']['id']))['labels']['zh']['value']): value[0]['type']=='time'?value[0]['value']['time']:value)

RETURN ZIP(UNION(['ID', '标签', '描述', '别名'],properties[*].label), UNION( [DOCUMENT(i)['_key'], TO_ARRAY(DOCUMENT(i).labels.zh.value), TO_ARRAY(DOCUMENT(i).descriptions.zh.value), DOCUMENT(i).aliases.zh[*].value],values))

实体

  1. 模糊搜索 提供通过关键词搜索实体目标的标签、描述、别名信息 要求：不区分大小写、不区分繁简
FOR doc IN entity_view

OR LIKE(doc.labels.zh.value, TOKENS(@keyword, "norm_en")[0])

}

值

  1. 查询年龄等于80的人物

分析：首先筛选属性值是数量类型且值等于80的边，在筛选属性是年龄

FOR document IN link

检索并导出
