For bachelor students we offer German lectures on database systems in addition to paper- or project-oriented seminars. Within a one-year bachelor project, students finalize their studies in cooperation with external partners. For master students we offer courses on information integration, data profiling, and information retrieval enhanced by specialized seminars, master projects and we advise master theses.

Short Paper accepted at LWDA 2019

We are happy to announce that our vision paper "A Scoring-based Approach for Data Preparator Suggestion" has been accepted at LWDA 2019.

Authors: Lan Jiang, Gerardo Vitagliano, and Felix Naumann

Abstract: Self-service data preparation enables end users to prepare data by themselves. However, the plethora of possible data preparation steps can overwhelm the user. We introduce a score-based preparator ranking approach to propose preparator candidates in a context-specific manner. To this end, we give scoring functions for a selected set of preparators and outline future work towards a full-fledged data preparation system.
