Semantic Space Clustering Recommender System

A Recommender System based on Semantic Space Clustering.

How to use

The MovieLens 1M database saved in the data directory only contains the movie names, so to gather the plots, genres and reviews you must first extract it from IMDb by running:

python datahandler/imdb_extractor.py

Once fetched the info, you can now run the Recommender System:

python3 main.py
