Question

Следующий алгоритм находит рейтинг страницы (обратите внимание, что это измененная версия алгоритма рейтинга страниц):

/* we have to go through all nodes */
MATCH (node:Page)
WITH
COLLECT(distinct node) AS pages
UNWIND pages as dest
  /* let's find all source citations for a given node */
  MATCH (source:Page)-[:NEXT]->(dest)
  WITH
    COLLECT(DISTINCT source) AS sources,
    dest AS dest
    UNWIND sources AS src
      /* we have to know how many relationships the source node has */
      MATCH (src)-[r:NEXT]->(dest)
      WITH src, dest, sum(r.weight) AS prob
      MATCH (src)-[r:NEXT]->()
      WITH
      /* The source citation will pass a portion of its pagerank as juice */
        src.pagerank * (prob/ sum(r.weight)) AS juice,
        dest AS dest
      /* now we have all information to update the destination node with the new pagerank */
      WITH
        sum(juice) AS p,
        dest AS dest
      /* Using damping factor d = 0.85 */
      set dest.pagerank = 0.15 + 0.85 * p;

Теперь для данного графика:

LOAD CSV WITH HEADERS FROM "file:\\graphUnioned1.csv" AS csvLine 
MERGE (s:Node {value:csvLine.s}) 
MERGE (o:Node {value:csvLine.o}) 
MERGE (s)-[:REL {weight: toFloat(csvLine.p)}]->(o);

Как сделатьЯ нахожу рейтинг страницы всех узлов на графике.Я хочу запустить вышеупомянутый алгоритм PageRank итеративно до 100 итераций
