Exporting the Result in CSV File
- 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 ...
- The following is an example Cypher query result:
- Example 1
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, Lethal Weapon Mercedes, K-12 student, Under 18, 3, The Rock ...
- Example 2
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 movie,2
