题目：Challenges of algorithmic intermediation
摘要：Intermediation platforms change our life, the way we are organized, and eventually the society as a whole. Intermediation platforms intermediate between people and services, giving for instance access to knowledge through search engines, or to vehicles with drivers through transportation networks. They disrupt an increasing number of actors because they offer innovative services which are rapidly adopted by large parts of the population. The new services are made possible by combining global data, essentially available, with personal data of their users, thus allowing a representation of the world at a granularity unthinkable in the past. Working in the virtual world, they do not in general have the constraints of producing the services in the real one. This young industry has a global reach, and enjoys booming capitalizations. In this talk, I will present the general mechanisms of algorithmic intermediation, including two-sided economic models, the fundamental externalities, as well as disintermediation mechanisms, which are common to all sectors.
报告人简介：Stéphane Grumbach, senior scientist at Inria, is a specialist of data. He has worked on complex data types, such as spatial, statistical, as well as biological data, and has designed a compression algorithm for DNA sequences. His main interests are targeted to topics at the intersection of disciplines. His current research focuses on the disruptions of the digital revolution, particularly on intermediation platforms, which transform data to create new economic and societal means.
He is director of IXXI, the Complex Systems Institute at ENS Lyon, promoting cross-disciplinary research to address contemporary challenges, and heads the Dice research group from Inria devoted to the Economy of Data.
He has been strongly involved in international relations, has spent eight years in China, first as a diplomat and then in the Chinese Academy of Sciences, where he headed the Sino-European IT Lab, LIAMA.
