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

shell pip install pybind11 pip install frankgraphbench==0.1.1

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

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

Usage

shell 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:

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

Framework for reproducible experiments usage

pip

We recommend using a python 3.8 virtual environment

shell pip install pybind11 pip install frankgraphbench

Usage

shell framework -c 'config_files/test.yml' Arguments: - -c: Experiment configuration file path.

The experiment config file should be a .yaml file like this:

```yaml experiment: dataset: name: ml-100k item: path: datasets/ml-100k/processed/item.csv extrafeatures: [movieyear, movietitle] user: path: datasets/ml-100k/processed/user.csv extrafeatures: [gender, occupation] ratings: path: datasets/ml-100k/processed/rating.csv timestamp: True enrich: mappath: datasets/ml-100k/processed/map.csv enrichpath: datasets/ml-100k/processed/enriched.csv remove_unmatched: False properties: - type: subject grouped: True sep: "::" - type: director grouped: True sep: "::"

preprocess: - method: filter_kcore parameters: k: 20 iterations: 1 target: user

split: seed: 42 test: method: k_fold k: 2 level: 'user'

models: - name: deepwalkbased config: saveweights: True parameters: walklen: 10 p: 1.0 q: 1.0 nwalks: 50 embedding_size: 64 epochs: 1

evaluation: k: 5 relevance_threshold: 3 metrics: [MAP, nDCG]

report: file: 'experimentresults/ml100kenriched/run1.csv' ```

See the config_files/ directory for more examples.

Chart generation for results usage

Chart generation module based on: https://github.com/hfawaz/cd-diagram

pip

We recommend using a python 3.8 virtual environment

shell pip install pybind11 pip install frankgraphbench

After obtaining results from some experiments

Usage

shell chart_generation [-h] -c CHART -p PERFORMANCE_METRIC -f INPUT_FILES -i INPUT_PATH -o OUTPUT_PATH -n FILE_NAME Arguments: - -h: Shows the help message. - -p: Name of the performance metric within the file to use for chart generation. - -f: List of .csv files to use for generating the chart. - -i: Path where results data to generate chart is located in .csv files. - -o: Path where generated charts will be placed. - -n: Add a name (and file extension) to the chart that will be generated.

Usage Example:

shell chart_generation -c 'cd-diagram' -p 'MAP@5' -f "['ml-100k.csv', 'ml-1m.csv', 'lastfm.csv', 'ml-100k_enriched.csv', 'ml-1m_enriched.csv', 'lastfm_enriched.csv']" -i 'experiment_results' -o 'charts' -n 'MAP@5.pdf'
