je le script suivant dans le Neo4j

CREATE (PaperA:Paper {title:'User Experience of Mobile Augmented 
Reality: A Review of Studies'}) CREATE (Irshad:Autor {name:'S. 
Irshad'}) CREATE (Rambli:Autor {name:'D. Rohaya Bt Awang Rambli'})

CREATE(Floris:Autor {name:'A. Floris'}) CREATE(Atzori:Autor {name:'L. 
Atzori'})

M.'}) CREATE(deAraújo:Autor {name:'de Araújo, I. L.'}) 
CREATE(Oliveira:Autor {name:'Oliveira, K. M.'}) CREATE(Maia:Autor 
{name:'Maia, M. E'}) 


CREATE(PaperD:Paper {title:'A QoE-aware Approach for Smart Home Energy 
Management'}) CREATE(Meloni:Autor {name:'Meloni, A'}) 
CREATE(Pilloni:Autor {name:'Pilloni, V.'}) 

(Irshad)-[:IS_AUTHOR]->(PaperA), (Rambli)-[:IS_AUTHOR]->(PaperA), 
(Floris)-[:IS_AUTHOR]->(PaperB), (Floris)- [:IS_AUTHOR] -> (PaperD), 
(Floris)- [:IS_AUTHOR] -> (PaperH), (Atzori)-[:IS_AUTHOR]->(PaperB), 
(Atzori)- [:IS_AUTHOR] -> (PaperD), (Atzori)- [:IS_AUTHOR] -> 
(PaperH), (Meloni)-[:IS_AUTHOR]->(PaperD), 
(Pilloni)-[:IS_AUTHOR]->(PaperD), (Andrade)-[:IS_AUTHOR]->(PaperC), 
(Carvalho)-[:IS_AUTHOR]->(PaperC), (deAraújo)-[:IS_AUTHOR]->(PaperC), 
(Oliveira)-[:IS_AUTHOR]->(PaperC), (Maia)-[:IS_AUTHOR]->(PaperC), 

comme un script Id qui renvoient les auteurs avec des papiers plus publiés, qui, dans ce cas est Floris et Atzori. J'utilise la version 3.0.8 de Neo4J.

Merci beaucoup.

Answer 1

EDIT:

modifié pour répondre correctement aux exigences de la question:

// First step: getting the greatest number of publications by author 
MATCH(author:Autor)-[r:IS_AUTHOR]->(:Paper) 
WITH author, count(r) as count 
ORDER BY count DESC LIMIT 1 
// Second step: getting all author who have number 
// of publications equals to `count` 
MATCH (a:Autor)-[r:IS_AUTHOR]->(p:Paper) 
WITH a, count, count(r) AS r WHERE r = count 
RETURN a 

La sortie sera:

╒════════════════════╕ 
│"a"     │ 
╞════════════════════╡ 
│{"name":"A. Floris"}│ 
├────────────────────┤ 
│{"name":"L. Atzori"}│ 
└────────────────────┘
