Dataflow Oriented Similarity Matching for Scientific Workflows
Bibliographic record
Abstract
Duplicate and redundant workflows can be avoided by encouraging workflow reuse. In this paper, we present how workflow similarity matching approach can be used to further enhance existing workflow modeling tools. Most existing workflow similarity algorithms cater for control-flow oriented types of workflow which are typically associated with business workflows. The increase presence of scientific workflows that are mainly dataflow oriented calls for workflow similarity matching that caters for these types of workflows instead. We demonstrate here how our work of applying a behavioral analysis technique (taking into consideration the causal footprint of the workflow) that has been used for finding similarity in business workflows perform when use for scientific workflows. The distinction of our technique is the use of data provenance within the scientific workflow model where positional information of the workflow activities are taken in consideration in order to find matching workflow models. Preliminary experiments have shown that our proposed solution provides a viable alternative for matching scientific workflows within multiple scenarios. Furthermore, our suggested approach performs better, particularly with the removal and extension types of modification to the original workflow.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
