Projects

Active Research Projects:

This project is an interdisciplinary research project in collaboration with VDE, Universität Tübingen, and Universität Viadrina.  The main goal of the project is to shed light on the role of AI training and testing data from a legal, ethical, informational and practical perspective. 

Project term: December 2021 to July 2023
Funded by: Federal Ministry of Labour and Social Affairs (BMAS)

 

The Metanome project is a project at HPI in cooperation with the Qatar Computing Reserach Institute (QCRI). Metanome provides a fresh view on data profiling by developing and integrating efficient algorithms into a common tool, expanding on the functionality of data profiling, and addressing performance and scalability issues for Big Data.

 

Completed Research Projects- PostDoc

Rating the value of a real-estate is a complex process relying on local and global properties. Working with a couple of million real-estate valuation data provided by the Deutsche Sparkassenverlag (DSV), the International Real Estate Business School (IREBS) of the University of Regensburg and HPI's Information Systems and the Algorithm Engineering groups collaborate to automate real-estate valuation by means of data engineering and artificial intelligence.

Project term: July 2020 to September 2021
Funded by: Deutscher Sparkassenverlag (DSV)
