Abstract: How to effectively recommend scientific workflow is a burning problem of importance.However,scientific workflow activity recommendation is ignored by most of existing researches.To facilitate scientific workflow design and improve its efficiency,by considering the characteristic of scientific workflow management system environment and user demand for interactive modeling,a method of scientific workflow activity recommendation for interactive modeling was proposed,which was named Scientific Workflow Activity Recommendation for interactive modeling (SWAR).It was started from scientific workflow repository and utilized scientific workflow fragments as reference models to provide recommendation in a context-sensitive manner.After clustering preprocessing scientific workflow fragments and computing the similarities between reference models and incomplete scientific workflow model,candidate scientific workflow activity set could be determined for recommendation.The result of experiments based on real datasets showed its effectiveness.

Key words: modeling, scientific workflow, workflow activity, recommendation
