Contextual Recommendations in Action - Bridging AI and Real-Life Economics


Achieving our action requires to establish of a dialogue between experts in information sciences and consumer sciences. On the one hand, data scientists need to develop algorithms to reveal consumer preferences and produce recommendations. On the other hand, behavior economists need to design deployments controlled experiences according to principles established in cognitive psychology and behavioral economics. These efforts enable to develop theories on how people make choices when assisted by decision-making algorithms and to measure acceptability. These two parties have been working together to feed off each other and deploy large-scale testing through platform and plug-in development. We have been collecting data and metadata to conduct a robust measurement of the impact of algorithmic decisions on individuals and on society. To achieve that, we have designed and deployed large-scale experiments for the observation of consumption of behaviors in a controlled environment. These deployments are being conducted and tested according to new definitions of satisfaction and adoption measures, and of course the development of algorithms, tools and novel human-centric data exploration and analysis approaches.


This document summarizes our action and the resulting challenges. During the first year, we organized three meetings during which we designed our experiences on AdAnalyst, developed a methodology for deploying experiences and modeling preferences, and obtained the necessary authorizations from Data Protection Officers and analyzed the risks associated with GDPR.

The list of our publications is available here, as well as a lexicon that we have developed to allow us to work together between computer scientists, economists and lawyers.
We have also contributed to the Digital Platforms and Algorithmic Risks working group as part of the GdR Internet et Société:
