The Higgs dataset has been built after monitoring the spreading processes on Twitter before, during and

after the announcement of the discovery of a new particle with the features of the elusive Higgs boson

on 4th July 2012.

Here are the summary statistics on the twitter data as shown in the web site.

Social Network statistics

Nodes 456626

Edges 14855842

Retweet Network statistics

Nodes 256491

Edges 328132

Reply Network statistics

Nodes 38918

Edges 32523

Mention Network statistics

Nodes 116408

Edges 150818

I uploaded the above nodes and relationship data to the Neo4J Graph database accessible at the same

endpoint that you used for the neo4j sample program.

The nodes use the label "User"

The four relationship edges use the following Labels :

Followers Social Network edge label "Follows"

Retweet Network edge label "Retweets"

Reply Network edge label "Replys"

Mention Network edge label "Mentions"

Now answer the following questions using Neo4J Graph queries. When executed your python program

should print the question and then print the answer to the question after that. You will need to submit

your Python code and program output from print statements.

1) your python program as a .py file, and

2) your program’s output as a text output

For the first three questions I have given you the queries given. Use these queries in your code, perform

the neo4J query transactions and print the results. For questions 4 onwards build the queries and print

the results.

1. How many total nodes with Label :User are there in the database? (1)

match (:User) return count(*) as User_Count

1. How many Social Network relationships are there in the database ? (1)

match ()-[follows:Follows]->() return count(follows)

1. How many Social Network followers does user 89805 have ? (1)

match (follower)-[:Follows]->(:User{user:89805}) return count(follower)

4. How many total times did users in this network retweet ? (1)

5. How many times did users in this network reply to other user's tweets ? (1)

6. How many times did users in this network mention other users in their tweets ? (1)

7. How many users follow user 89805 ? (1)

8. How many users does user 89805 follow ? (1)

9. Did user 14907 ever retweet user 89805 ? (2)

10. Did user 89805 ever retweet user 14907 ? (2)

11. Find out the top 5 users with the highest number of followers ? (3)

12. What is the total count of followers of followers of user 89805 ? (3)

13. Explore and find some interesting statistic from the data. Print out what you found. (2)

Here is a good neo4j reference on the Cypher language. You can use it to learn simple and advanced

queries and operations on neo4j.
