Feature-Model Benchmark

Our comprehensive feature collection provides large, real-world feature models for empirical evaluations. All currently available feature models, including jsons indicating characteristics and sources of the respective feature models, can be found in feature_models/original/. Further, we provide a .csv file showcasing information for every feature model in statistics/Complete.csv. We offer additional functionality to make use of the collection more convenient. Users can search for a subset of feature models, create configuration files indicating their subset, and create subsets from existing configuration files.

Included Feature Models

As of now, 2,518 feature models our included in our collection covering various domains. Below you can find an overview about the include feature models. For more details on the feature models, we refer to statistics/Complete.csv.

Repository Structure

The directory feature_models/ contains the feature models in original, dimacs, and uvl format. Note that feature models originally in dimacs or UVL format are stored in original with no redundant copy in dimacs or UVL, respectively. To get all feature models in the specific format, use the extraction script which will take care of such models for you. See below for usage examples.

scripts includes some scripts to interact with the collection. If you want to use the dataset, scripts/extract_collection.py should the most relevant for you to extract your collection. scripts/dimacs_tools.py provides several capabilities to preprocess dimacs files. scripts/manage_statistics.py is used to update the statistics files in statistics/ after adding or updating feature models.

Extracting Feature-Model Collections

Setup

The script is based on Python3. To install the required dependencies please use:

pip3 install -r requirements.txt

Usage

scripts/extract_collection.py can be used to create a filtered subset of the feature model collection.

Show help for the different parameters that can be used for filtering:

python3 scripts/extract_collection.py -h

Example Extraction Procedures

Create collection with feature models between 500 and 2,000 features in UVL format:

python3 scripts/extract_collection.py --features 500..2000 --output_format uvl

Create collection with feature models from the automotive domain:

python3 scripts/extract_collection.py --domains automotive

Create collection with feature models in UVL format from the systems-software domain with at least 500 features

python3 scripts/extract_collection.py --features 500.. --domains systems_software --output_format uvl

Create collection with all feature models but early versions of a history:

python3 scripts/extract_collection.py --versions last

Create collection with feature models for which a history is available:

python3 scripts/extract_collection.py --evolution

Create collection with same feature models as specified in configuration json:

python3 scripts/extract_collection.py --load_config paper_configs/Krieter2020.json

Create collection with all feature models in UVL with a flat hierarchy in the target directory: python3 scripts/extract_collection.py --output_format uvl --flat

Contributing

We highly appreciate if new feature models are added by the community via PR to this repository. For every (group of) feature models, we require a json that indicates some meta information on the origin of the feature model. See an example below for the format. Please provide at least: Name, Year, OriginalFormat, Publication, and Source.
