The 1st "IPSDS Talks" takes place on February 20, 2016 at the University of Mannheim (14:00-16:30). IPSDS (International Program in Survey and Data Science) Talks is dedicated to modern data collection methods. 
Keynote: "Importance of Surveys in the Era of Big Data" by Mario Callegaro (Google)
Abstract: With the availability of big data, some people are predicting the decline and eventual end of surveys. In this talk, Mario will discuss the relationship between big data and surveys and how a survey researcher can help in answering research questions in a big organization. Mario will also dispute the notion that surveys are in decline challenging the data that are generally provided to support this theory. Finally, the discussion will move to a new way of thinking about surveys moving from a concept of sampling individuals, to sampling big data events to trigger a survey.
