FranKGraphBench: Knowledge Graph Aware Recommender Systems Framework for Benchmarking

The FranKGraphBench is a framework to allow KG Aware RSs to be benchmarked in a reproducible and easy to implement manner. It was first created on Google Summer of Code 2023 for Data Integration between DBpedia and some standard RS datasets in a reproducible framework.

Check the docs for more information.

• This repository was first created for Data Integration between DBpedia and some standard Recommender Systems datasets and a framework for reproducible experiments. For more info, check the project proposal and the project progress with weekly (as possible) updates.

Data Integration Usage

pip

We recommend using a python 3.8 virtual environment

pip install pybind11
pip install frankgraphbench

Install the full dataset using bash scripts located at datasets/:

cd datasets
bash ml-100k.sh # Downloaded at `datasets/ml-100k` folder
bash ml-1m.sh   # Downloaded at `datasets/ml-1m` folder

Usage

data_integration [-h] -d DATASET -i INPUT_PATH -o OUTPUT_PATH [-ci] [-cu] [-cr] [-cs] [-map] [-w]

Arguments:

• -h: Shows the help message.
• -d: Name of a supported dataset. It will be the same name of the folder created by the bash script provided for the dataset. For now, check data_integration/dataset2class.py to see the supported ones.
• -i: Input path where the full dataset is placed.
• -o: Output path where the integrated dataset will be placed.
• -ci: Use this flag if you want to convert item data.
• -cu: Use this flag if you want to convert user data.
• -cr: Use this flag if you want to convert rating data.
• -cs: Use this flag if you want to convert social link data.
• -map: Use this flag if you want to map dataset items with DBpedia. At least the item data should be already converted.
• -w: Choose the number of workers(threads) to be used for parallel queries.

Usage Example:

data_integration -d 'ml-100k' -i 'datasets/ml-100k' -o 'datasets/ml-100k/processed' \
    -ci -cu -cr -map -w 8
