PyKEEN (Python KnowlEdge EmbeddiNgs) is a Python package designed to train and evaluate knowledge graph embedding models (incorporating multi-modal information).
Installation • Quickstart • Datasets (36) • Inductive Datasets (5) • Models (44) • Support • Citation
## Installation   The latest stable version of PyKEEN requires Python 3.8+. It can be downloaded and installed from [PyPI](https://pypi.org/project/pykeen) with: ```shell pip install pykeen ``` The latest version of PyKEEN can be installed directly from the source code on [GitHub](https://github.com/pykeen/pykeen) with: ```shell pip install git+https://github.com/pykeen/pykeen.git ``` More information about installation (e.g., development mode, Windows installation, Colab, Kaggle, extras) can be found in the [installation documentation](https://pykeen.readthedocs.io/en/latest/installation.html). ## Quickstart [](https://pykeen.readthedocs.io/en/latest/?badge=latest) This example shows how to train a model on a dataset and test on another dataset. The fastest way to get up and running is to use the pipeline function. It provides a high-level entry into the extensible functionality of this package. The following example shows how to train and evaluate the [TransE](https://pykeen.readthedocs.io/en/latest/api/pykeen.models.TransE.html#pykeen.models.TransE) model on the [Nations](https://pykeen.readthedocs.io/en/latest/api/pykeen.datasets.Nations.html#pykeen.datasets.Nations) dataset. By default, the training loop uses the [stochastic local closed world assumption (sLCWA)](https://pykeen.readthedocs.io/en/latest/reference/training.html#pykeen.training.SLCWATrainingLoop) training approach and evaluates with [rank-based evaluation](https://pykeen.readthedocs.io/en/latest/reference/evaluation/rank_based.html#pykeen.evaluation.RankBasedEvaluator). ```python from pykeen.pipeline import pipeline result = pipeline( model='TransE', dataset='nations', ) ``` The results are returned in an instance of the [PipelineResult](https://pykeen.readthedocs.io/en/latest/reference/pipeline.html#pykeen.pipeline.PipelineResult) dataclass that has attributes for the trained model, the training loop, the evaluation, and more. See the tutorials on [using your own dataset](https://pykeen.readthedocs.io/en/latest/byo/data.html), [understanding the evaluation](https://pykeen.readthedocs.io/en/latest/tutorial/understanding_evaluation.html), and [making novel link predictions](https://pykeen.readthedocs.io/en/latest/tutorial/making_predictions.html). PyKEEN is extensible such that: - Each model has the same API, so anything from ``pykeen.models`` can be dropped in - Each training loop has the same API, so ``pykeen.training.LCWATrainingLoop`` can be dropped in - Triples factories can be generated by the user with ``from pykeen.triples.TriplesFactory`` The full documentation can be found at https://pykeen.readthedocs.io. ## Implementation Below are the models, datasets, training modes, evaluators, and metrics implemented in ``pykeen``. ### Datasets The following 36 datasets are built in to PyKEEN. The citation for each dataset corresponds to either the paper describing the dataset, the first paper published using the dataset with knowledge graph embedding models, or the URL for the dataset if neither of the first two are available. If you want to use a custom dataset, see the [Bring Your Own Dataset](https://pykeen.readthedocs.io/en/latest/byo/data.html) tutorial. If you have a suggestion for another dataset to include in PyKEEN, please let us know [here](https://github.com/pykeen/pykeen/issues/new?assignees=cthoyt&labels=New+Dataset&template=dataset-request.md&title=Add+%5BDATASET+NAME%5D). | Name | Documentation | Citation | Entities |

PyKEEN (Python KnowlEdge EmbeddiNgs) is a Python package designed to train and evaluate knowledge graph embedding models (incorporating multi-modal information).
Installation • Quickstart • Datasets (36) • Inductive Datasets (5) • Models (44) • Support • Citation
## Installation   The latest stable version of PyKEEN requires Python 3.8+. It can be downloaded and installed from [PyPI](https://pypi.org/project/pykeen) with: ```shell pip install pykeen ``` The latest version of PyKEEN can be installed directly from the source code on [GitHub](https://github.com/pykeen/pykeen) with: ```shell pip install git+https://github.com/pykeen/pykeen.git ``` More information about installation (e.g., development mode, Windows installation, Colab, Kaggle, extras) can be found in the [installation documentation](https://pykeen.readthedocs.io/en/latest/installation.html). ## Quickstart [](https://pykeen.readthedocs.io/en/latest/?badge=latest) This example shows how to train a model on a dataset and test on another dataset. The fastest way to get up and running is to use the pipeline function. It provides a high-level entry into the extensible functionality of this package. The following example shows how to train and evaluate the [TransE](https://pykeen.readthedocs.io/en/latest/api/pykeen.models.TransE.html#pykeen.models.TransE) model on the [Nations](https://pykeen.readthedocs.io/en/latest/api/pykeen.datasets.Nations.html#pykeen.datasets.Nations) dataset. By default, the training loop uses the [stochastic local closed world assumption (sLCWA)](https://pykeen.readthedocs.io/en/latest/reference/training.html#pykeen.training.SLCWATrainingLoop) training approach and evaluates with [rank-based evaluation](https://pykeen.readthedocs.io/en/latest/reference/evaluation/rank_based.html#pykeen.evaluation.RankBasedEvaluator). ```python from pykeen.pipeline import pipeline result = pipeline( model='TransE', dataset='nations', ) ``` The results are returned in an instance of the [PipelineResult](https://pykeen.readthedocs.io/en/latest/reference/pipeline.html#pykeen.pipeline.PipelineResult) dataclass that has attributes for the trained model, the training loop, the evaluation, and more. See the tutorials on [using your own dataset](https://pykeen.readthedocs.io/en/latest/byo/data.html), [understanding the evaluation](https://pykeen.readthedocs.io/en/latest/tutorial/understanding_evaluation.html), and [making novel link predictions](https://pykeen.readthedocs.io/en/latest/tutorial/making_predictions.html). PyKEEN is extensible such that: - Each model has the same API, so anything from ``pykeen.models`` can be dropped in - Each training loop has the same API, so ``pykeen.training.LCWATrainingLoop`` can be dropped in - Triples factories can be generated by the user with ``from pykeen.triples.TriplesFactory`` The full documentation can be found at https://pykeen.readthedocs.io. ## Implementation Below are the models, datasets, training modes, evaluators, and metrics implemented in ``pykeen``. ### Datasets The following 36 datasets are built in to PyKEEN. The citation for each dataset corresponds to either the paper describing the dataset, the first paper published using the dataset with knowledge graph embedding models, or the URL for the dataset if neither of the first two are available. If you want to use a custom dataset, see the [Bring Your Own Dataset](https://pykeen.readthedocs.io/en/latest/byo/data.html) tutorial. If you have a suggestion for another dataset to include in PyKEEN, please let us know [here](https://github.com/pykeen/pykeen/issues/new?assignees=cthoyt&labels=New+Dataset&template=dataset-request.md&title=Add+%5BDATASET+NAME%5D). | Name | Documentation | Citation | Entities |

PyKEEN includes a set of curated experimental settings for reproducing past landmark experiments. They can be accessed and run like: ```shell pykeen experiments reproduce tucker balazevic2019 fb15k ``` Where the three arguments are the model name, the reference, and the dataset. The output directory can be optionally set with `-d`. ### Ablation PyKEEN includes the ability to specify ablation studies using the hyper-parameter optimization module. They can be run like: ```shell pykeen experiments ablation ~/path/to/config.json ``` ### Large-scale Reproducibility and Benchmarking Study We used PyKEEN to perform a large-scale reproducibility and benchmarking study which are described in [our article](https://doi.org/10.1109/TPAMI.2021.3124805): ```bibtex @article{ali2020benchmarking, author={Ali, Mehdi and Berrendorf, Max and Hoyt, Charles Tapley and Vermue, Laurent and Galkin, Mikhail and Sharifzadeh, Sahand and Fischer, Asja and Tresp, Volker and Lehmann, Jens}, journal={IEEE Transactions on Pattern Analysis and Machine Intelligence}, title={Bringing Light Into the Dark: A Large-scale Evaluation of Knowledge Graph Embedding Models under a Unified Framework}, year={2021}, pages={1-1}, doi={10.1109/TPAMI.2021.3124805}} } ``` We have made all code, experimental configurations, results, and analyses that lead to our interpretations available at https://github.com/pykeen/benchmarking. ## Contributing Contributions, whether filing an issue, making a pull request, or forking, are appreciated.

PyKEEN (Python KnowlEdge EmbeddiNgs) is a Python package designed to train and evaluate knowledge graph embedding models (incorporating multi-modal information).
Installation • Quickstart • Datasets (36) • Inductive Datasets (5) • Models (44) • Support • Citation
## Installation   The latest stable version of PyKEEN requires Python 3.8+. It can be downloaded and installed from [PyPI](https://pypi.org/project/pykeen) with: ```shell pip install pykeen ``` The latest version of PyKEEN can be installed directly from the source code on [GitHub](https://github.com/pykeen/pykeen) with: ```shell pip install git+https://github.com/pykeen/pykeen.git ``` More information about installation (e.g., development mode, Windows installation, Colab, Kaggle, extras) can be found in the [installation documentation](https://pykeen.readthedocs.io/en/latest/installation.html). ## Quickstart [](https://pykeen.readthedocs.io/en/latest/?badge=latest) This example shows how to train a model on a dataset and test on another dataset. The fastest way to get up and running is to use the pipeline function. It provides a high-level entry into the extensible functionality of this package. The following example shows how to train and evaluate the [TransE](https://pykeen.readthedocs.io/en/latest/api/pykeen.models.TransE.html#pykeen.models.TransE) model on the [Nations](https://pykeen.readthedocs.io/en/latest/api/pykeen.datasets.Nations.html#pykeen.datasets.Nations) dataset. By default, the training loop uses the [stochastic local closed world assumption (sLCWA)](https://pykeen.readthedocs.io/en/latest/reference/training.html#pykeen.training.SLCWATrainingLoop) training approach and evaluates with [rank-based evaluation](https://pykeen.readthedocs.io/en/latest/reference/evaluation/rank_based.html#pykeen.evaluation.RankBasedEvaluator). ```python from pykeen.pipeline import pipeline result = pipeline( model='TransE', dataset='nations', ) ``` The results are returned in an instance of the [PipelineResult](https://pykeen.readthedocs.io/en/latest/reference/pipeline.html#pykeen.pipeline.PipelineResult) dataclass that has attributes for the trained model, the training loop, the evaluation, and more. See the tutorials on [using your own dataset](https://pykeen.readthedocs.io/en/latest/byo/data.html), [understanding the evaluation](https://pykeen.readthedocs.io/en/latest/tutorial/understanding_evaluation.html), and [making novel link predictions](https://pykeen.readthedocs.io/en/latest/tutorial/making_predictions.html). PyKEEN is extensible such that: - Each model has the same API, so anything from ``pykeen.models`` can be dropped in - Each training loop has the same API, so ``pykeen.training.LCWATrainingLoop`` can be dropped in - Triples factories can be generated by the user with ``from pykeen.triples.TriplesFactory`` The full documentation can be found at https://pykeen.readthedocs.io. ## Implementation Below are the models, datasets, training modes, evaluators, and metrics implemented in ``pykeen``. ### Datasets The following 36 datasets are built in to PyKEEN. The citation for each dataset corresponds to either the paper describing the dataset, the first paper published using the dataset with knowledge graph embedding models, or the URL for the dataset if neither of the first two are available. If you want to use a custom dataset, see the [Bring Your Own Dataset](https://pykeen.readthedocs.io/en/latest/byo/data.html) tutorial. If you have a suggestion for another dataset to include in PyKEEN, please let us know [here](https://github.com/pykeen/pykeen/issues/new?assignees=cthoyt&labels=New+Dataset&template=dataset-request.md&title=Add+%5BDATASET+NAME%5D). | Name | Documentation | Citation | Entities |

PyKEEN includes a set of curated experimental settings for reproducing past landmark experiments. They can be accessed and run like: ```shell pykeen experiments reproduce tucker balazevic2019 fb15k ``` Where the three arguments are the model name, the reference, and the dataset. The output directory can be optionally set with `-d`. ### Ablation PyKEEN includes the ability to specify ablation studies using the hyper-parameter optimization module. They can be run like: ```shell pykeen experiments ablation ~/path/to/config.json ``` ### Large-scale Reproducibility and Benchmarking Study We used PyKEEN to perform a large-scale reproducibility and benchmarking study which are described in [our article](https://doi.org/10.1109/TPAMI.2021.3124805): ```bibtex @article{ali2020benchmarking, author={Ali, Mehdi and Berrendorf, Max and Hoyt, Charles Tapley and Vermue, Laurent and Galkin, Mikhail and Sharifzadeh, Sahand and Fischer, Asja and Tresp, Volker and Lehmann, Jens}, journal={IEEE Transactions on Pattern Analysis and Machine Intelligence}, title={Bringing Light Into the Dark: A Large-scale Evaluation of Knowledge Graph Embedding Models under a Unified Framework}, year={2021}, pages={1-1}, doi={10.1109/TPAMI.2021.3124805}} } ``` We have made all code, experimental configurations, results, and analyses that lead to our interpretations available at https://github.com/pykeen/benchmarking. ## Contributing Contributions, whether filing an issue, making a pull request, or forking, are appreciated.
