Final Presentation Day (Data Science Toolbox)

February 7th, 2019

Things got serious for students of our Data Science Toolbox course on Thursday at ECDF. After weeks of preparation, nine teams presented their results on the topic of data-driven decision-making for a better future. The case studies included the creation of a prototype, drawing on the Boston open data initiative for supporting business and public leaders in the areas of financial services, public services, and sustainability.

Sponsored by Accenture Strategy, three outstanding teams were awarded with all-in invitations for a get-together at Solar Bar & Restaurant, taking place in April.

Airbnb Literature Review

January 15th, 2019

A growing body of research from various domains has investigated the platform Airbnb, a two-sided market for peer-based accommodation sharing. We set out from the idea that it is due time to take a step back and assess the current state of affairs.

We are happy to announce that our comprehensive review article on Airbnb has eventually appeared, aiming to conflate and synthesize research on Airbnb. Moreover, a growing online repository on Airbnb-related research is now available.

Pairing Research Talks during the Berlin Science Week

November 1st, 2018

What creates trust in online platforms? What is the economic value of online reputation? How can reputation be transferred from one platform to another?

Hidden peer-to-peer network structures

September 19th, 2018

We are happy to announce that our paper on the hidden peer-to-peer network structures within accommodation sharing was accepted at the Journal of Systems and Information Technology.

The paper provides first insights into the very fabric of host-guest interactions on Airbnb from a macroscopic perspective. We discuss how the platform's network topology may be leveraged as a resource for trust-building and how platform operators may use network analyses to gain deeper insights into their user base.
