Minimal IND Repairs

Setup

1. The code is written using Java 21.
2. Install dependencies and build the project with mvn install

Configuration

You can configure the execution using a JSON file. There are example configurations (in the configs directory) for the three datasets used in the paper.

The most important configuration options are:

• filePrefix: the directory where the dataset is located (remember trailing /)
• dependencies: the dependencies that should be repaired (this is also the order of dependencies for PIRANHA)
• matchingType: algorithm used to do the repair (one of EQUALITY, GROUND_TRUTH, PIRANHA, CHROMIDE, GOBIES)
• distanceMeasure: the distance measure used to create the general metric space (these must be precomputed)
• computeDistances: boolean to precompute the distances
• linkage: linkage function for the hierarchical clustering to generate the tree metric space
• numThreads: the number of threads used for parallelized parts of the code
• visualizeResult: show changes done by the repair
• verbose: boolean to turn on verbose output
