}You need to download the dataset and place it into the folder ./data/raw such that the models are in ./data/raw/sap_sam_2022/models.
It is also possible to run the analysis on any
.sgxfiles (Signavio workspace exports). Place the files in./data/raw/sap_sam_2022/modelsand the conversion will be performed automatically.
To get started on Mac or Windows, we provide a dependency setup with poetry.
Make sure poetry is installed on your system with poetry --version. If not, run pip poetry install.
To install the dependencies, do to the root of the cloned repository, type this line in the terminal, and press enter:
poetry installIt is important to note that you should have the latest stable version of
pythonorpython3installed on your machine, and not a pre-release one (trypython --version). The current latest stable version is3.12.2(as of April 2024).
After executing the script, you should be able to setup the kernel:
python -m ipykernel install --user --name=sap-sam-kernelThen, to open the project, simply type:
jupyter notebookAlternatively, a conda setup is possible.
We provide two conda environment.yml files that can be used to create a new environment and install the required dependencies:
environment.yml: contains the abstract dependencies (pandas, numpy, ...).environment-lock.yml: contains versions for all dependencies and the transitive dependencies to ensure reproducible results.
You can use the following conda command to create the environment:
conda env create -f environment.yml or
conda env create -f environment-lock.yml We provide a tutorial Jupyter Notebook that illustrates the dataset format in more detail and shows how to use the csv parsers developed in ./src.
The properties Jupyter Notebook gives an overview of selected properties of the dataset.
The SAP-SAM dataset contains 103 csv files with a rough size of 38 GB of process models (see modeling notations of the models below).
- csv columns:
- Revision ID: Unique identifier for model revision
- Model ID: Unique identifier for model
- Organization ID: Unique identifier for organization this model originates from
- Datetime: Date and time of creation
- Model JSON: JSON containing model information
- Description: Description of model (typically empty)
- Name: Model name
- Type: Model type (duplicate and less specific than namespace)
- Namespace: Stencilset/modeling notation (e.g. BPMN, DMN, UML,...)
- Number of models: 1,021,471
- Number of models by modeling notation:
| Modeling notation | Frequency |
|---|---|
| BPMN 2.0 | 618,807 |
| Value Chain | 194,078 |
| DMN 1.0 | 98,286 |

In order to remove personal first and last names, emails or in some cases matriculations numbers (which users have added in non-compliance with the T&Cs), we have applied a simple replacement script. In particular, we have replaced - to the extent possible - emails, names, and (matriculation) numbers with the following dummy values:
| Context | Dummy |
|---|---|
| Email Dummy | [email protected] |
| Name Dummy | Jane Doe |
| Matriculation/Number Dummy | 12345678 |
