Exporting the Result in CSV File

1. The following is an example of the algorithm execution result, for example, content of Louvain.csv:

   # modularity: 0.4269691347613425,
   #community_num: 4,
   #runtime: 0.003784,
   #data_total_size: 34
   #community:
   1,1
   2,1
   ...
   
   

2. The following is an example Cypher query result:
   • Example 1

     Query statement:

     match (n:user)-[r]->(m:movie) return id(n),n.Name, n.Occupation, n.Age,r.Score,m.Title
     
     

     Result:

     #data_total_size:1209
     #data_return_size:1209
     #data_offset:0
     #records:
     Vivian, artist, 25-34, 5, Lethal Weapon
     Vivian, Artist, 25-34, 4, Raising Arizona

     Mercedes, K-12 student, Under 18, 3, The Rock
     ...
     
     

   • Example 2

     Query statement:

     match (n)-->(m) where id(n)='Vivian' return labels(m),count(*)
     
     

     Result:

     #data_total_size:2
     #data_return_size:2
     #data_offset:0
     #records:
     user,5
