With regard to our previous work on the adaptation of business workflows, we discuss the differences between the workflow types and the implications for transferring the approaches to scientific workflows. An experimental evaluation with RapidMiner workflows demonstrates that the approaches can significantly improve workflows towards a given query while mostly maintaining their executability and semantic correctness. |

| 1. | Malburg, Lukas; Münster, Nicolas; Zeyen, Christian; Bergmann, Ralph Query Model and Similarity-Based Retrieval for Workflow Reuse in the Digital Humanities (Proceedings Article) In: Gemulla, Rainer; Ponzetto, Simone Paolo; Bizer, Christian; Keuper, Margret; Stuckenschmidt, Heiner (Ed.): Proceedings of the Conference “Lernen, Wissen, Daten, Analysen”, LWDA 2018, pp. 251–262, CEUR-WS.org, 2018. @inproceedings{malburg_workflow_reuse_2018,Scientific Workflows do not seem to be broadly used today in the Digital Humanities to perform text and data analysis. Although they have become established in e-Science, modeling new workflows is usually a demanding task, especially for novice users. Case-Based Reasoning (CBR) has been applied in the past to support the development of workflows as an experience-based activity by retrieving past workflows. A query language is needed for this purpose, but current languages do not sufficiently consider different user groups and the information they can provide. To address this issue, we present a query model to support novice as well as experienced users. We identify common expression elements from literature and integrate them in a prototypical CBR application named Reuse Assistant to support workflow reuse in the RapidMiner workflow tool. An experimental evaluation with non-expert users indicates the potential of the Reuse Assistant to facilitate workflow reuse and thus to simplify workflow development. |
