Stephan Karpischek defended his thesis on mobile barcode scanning and quality of product master data

Stephan Karpischek is, after Irena Pletikosa, the second the PhD student this week and my fifth in total successfully defending his thesis. Congratulations, Dr. Stephan Karpischek!
As his co-referee Sanjay Sarma from MIT could not attend in person, Stephan defended his thesis in a sophisticated conference room at ETH where we had high-quality connection to MIT. The quality of video and sound was amazing and prove that some travels can be indeed eliminated by these technologies.
Stephan outlined four contributions of his thesis: the implementation of the open-source mobile barcode scanning app [1], the proof of incorrect master data yielding lower usage of mobile apps [2], the introduction of a
method to measure correctness of product names and its application to public master data sources [3]. Additionally, Stephan also did
some remarkable analysis of user behavior of mobile bargaining [4] and developed one of the most renown Swiss apps [5] , Swisspeaks. However, both results did not really fit any more in his thesis "Mobile Barcode Scanning Applications for Consumers" (will be available in a couple of months here).
 In the Q and A section of his defense Stephan prove that roughly 2% of today's master data available in online data pools amazon, google, etc. are wrong, dillute the brand image and could yield financial losses. This result provides a fact-based justification of the GS1's emerging Trusted Source service [6] which aims at providing brand-owner approved master-data. He also gave a perspective of a future master-data monitoring service that brand-owners could use to measure their appearance and abuse of their barcodes by other parties on the network...
Stephan, it has been a great pleasure to working with you and I really enjoyed the inspiring discussion with you. I wish you good luck in your new job!
