Heterogeneous Information Network-Based Scientific Workflow Recommendation for Complex Applications

Abstract EN

Scientific workflow is a valuable tool for various complicated large-scale data processing applications.

In recent years, the increasingly growing number of scientific processes available necessitates the development of recommendation techniques to provide automatic support for modelling scientific workflows.

In this paper, with the help of heterogeneous information network (HIN) and tags of scientific workflows, we organize scientific workflows as a HIN and propose a novel scientific workflow similarity computation method based on metapath.

In addition, the density peak clustering (DPC) algorithm is introduced into the recommendation process and a scientific workflow recommendation approach named HDSWR is proposed.

The effectiveness and efficiency of our approach are evaluated by extensive experiments with real-world scientific workflows.
