Movielens dataset in neo4j

Needs a lib/ directory with neo4j-community-1.9.RC1 unzipped inside http://www.neo4j.org/download

Dataset from the movilens page : wget http://www.grouplens.org/system/files/ml-100k.zip The data are expected in the ml-100k/ directory after extraction

Imported as a graph:

  • user node (with properties as in u.user)
  • movie node (with properties as in u.item)
  • genre node (linked to movie)
  • occupation node (linked to user)

For simplicity the rating will be transformed to a like/dislike relationship. LIKE if rating > 2 else DISLIKE.

To use it chmod +x run.sh ./run.sh

(A lot of cleaning left to do, but will do the job !!) TODO : separate the reading of data files and the import in neo4j
