Ricardo Baeza-Yates (former Yahoo Labs Vice-president) will talk about the "Bias in the Web"


On June 8, 2017 the Faculty of Informatics is welcoming Ricardo A. Baeza-Yates, former Yahoo Labs Vice-president and currently CTO in NTENT, a semantic search company in South California. The Chilean-Spanish computer scientist will talk about the “Bias in the Web” at the upcoming Vienna Gödel Lecture 2017.

Bias in the Web

The Web is the most powerful communication medium and the largest public data repository that humankind has created. Its content ranges from great reference sources such as Wikipedia to ugly fake news. Indeed, social (digital) media is just an amplifying mirror of ourselves. Hence, the main challenge of search engines and other websites that rely on web data is to assess the quality of such data. However, as all people have their own biases, web content as well as our web interactions are tainted with many biases.

Data bias includes redundancy and spam, while interaction bias includes activity and presentation bias. In addition, sometimes algorithms add bias, particularly in the context of search and recommendation systems. As bias generates bias, we stress the importance of debiasing data as well as using the context and other techniques such as explore & exploit, to break the filter bubble. The main goal of this talk is to make people aware of the different biases that affect all of us on the Web. Awareness is the first step to be able to fight and reduce the vicious cycle of bias.

Vienna Gödel Lecture

The annual “Vienna Gödel Lectures of the Faculty of Informatics” were established in 2013. The aim of the annual Vienna Gödel Lectures of the Faculty of Informatics is to increase Vienna‘s visibility as an academic hotspot of computer science. The series emphasizes the importance of computer science and its significant contribution to explaining and shaping the world in which we live today. The lecture series is named after the famous mathematician and logician Kurt Gödel, who accomplished essential parts of his scientic work in Vienna, and was inaugurated in 2013 with a talk by Donald E. Knuth.
