MovieLens Data Sets Project
Project data set
- This data set contains 10000054 ratings and 95580 tags applied to 10681 movies by 71567 users of the online movie recommender service MovieLens.
- Link to data set: http://www.grouplens.org/node/12
Project Tasks
1. Identifying and downloading the target data set
- The downloaded data is on cluster at: /cluster/home/mmludin08/Big-Data-M
2. Data cleaning and per-processing
- The original data was in the .dat format. one perl script and a python script was written to change the formate and clean the data.
3. Load the data into your Postgres instance
- After the cleaning the data was uploaded to cluster and laptop machine.
4. Develop queries to explore your ideas in the data
- SQL statements with results are on cluster: /cluster/home/mmludin08/Big-Data-M
5. Develop and document the model function you are exploring in the data
- For this project my aim was to discover the movie genres time line. In more words, I wanted to find out at what period of time people watch what type of movies. I also tried to look for the pattern
6. Develop a visualization to show the model/patterns in the data
Tech Details
- Node: as7
- Path to storage space: /scratch/big-data/mobeen
Results
- The visualization(s)
- The story
