DP-Bench: A Benchmark for Evaluating Data Product Creation Systems

The DP-Bench (shortened from Data Product Benchmark) is the first of its kind benchmark.

It contains -

  • Description of specific business use cases, which we call data product requests (DPRs)
  • Corresponding data products for each of these DPRs, which consist of a subset of database tables and columns which are relevant to the DPR as well as derived columns which are produced from existing columns in the database
  • Provenance (in SQL) for the derived columns in the data products
  • Actual DB schemas from which these data products were created
  • Natural language questions corresponding to each business usecase
  • Annotated topics for the DPRs and annotated topics for the data products.
