CALL gds.pagerank.stream 问题 [英] CALL gds.pagerank.stream problems

问题描述

:param label =>('人');:param 关系类型 =>('HAS_EMAILED');:param 限制 =>(100);:param 配置 =>({并发:8，方向:'传出'，weightProperty:空，defaultValue:1，dampingFactor:0.85，迭代次数:25，writeProperty:'网页排名'});//然后我们用一个简单的命令计算pagerank调用 algo.pageRank($label, $relationshipType, $config);

:param label => ('Person'); :param relationshipType => ('HAS_EMAILED'); :param limit => ( 100); :param config => ({concurrency: 8, direction: 'Outgoing', weightProperty: null, defaultValue: 1, dampingFactor: 0.85, iterations: 25, writeProperty: 'pagerank'}); //then we calculate pagerank with one simple command CALL algo.pageRank($label, $relationshipType, $config);

如何把它变成CALL gds.pagerank.stream(...)?

推荐答案

我的解决方案:

:param label => ('Person'); :param relationshipType => ('HAS_EMAILED'); :param limit => ( 100); :param config => ({concurrency: 8, direction: 'Outgoing', weightProperty: null, defaultValue: 1, dampingFactor: 0.85, iterations: 25, writeProperty: 'pagerank'});

CALL gds.graph.create(
    'myGraph332',
    'Person',    { HAS_EMAILED:{orientation:'UNDIRECTED'}    })

然后

CALL gds.pageRank.stream('myGraph332')

YIELD nodeId, score

RETURN gds.util.asNode(nodeId).alias AS alias, score

ORDER BY score DESC, alias ASC
