Pipeline Provenance for Analysis, Evaluation, Trust or Reproducibility

Kurzfassung

Data volumes and rates of research infrastructures will continue to increase in the upcoming years and impact how we interact with their final data products. Little of the processed data can be directly investigated and most of it will be automatically processed with as little user interaction as possible. Capturing all necessary information of such processing ensures reproducibility of the final results and generates trust in the entire process. We present Pipeline pRovenance for Analysis, Evaluation, Trust Or Reproducibility (PRAETOR), a software suite that enables automated generation, modeling, and analysis of provenance information of Python pipelines. Furthermore, the evaluation of the pipeline performance, based upon a user defined quality matrix in the provenance, enables the first step of machine learning processes, where such information can be fed into dedicated optimization procedures.
