Dear ACM Chicago member,

Our November webinar is this Wednesday, November 17 at 12 PM CDT (note the time change from the usual 6 PM).  Our speaker is Prof. Christoph Trattner from University of Bergen, Norway.  See details below.

Understanding, Predicting & Changing Eating Habits on the Web

Speaker: Christopher Trattner,
ACM Distinguished Speaker

Wednesday, November 17, 2021

12:00 PM (Noon) to 1:00 PM CDT

Online Event

Admission: Free, General Admission, open to the public, registration required.

According to the World Health Organization around 80% of cases of heart disease, strokes and type 2 diabetes could be avoided if people were to implement a healthier diet. Computational data analytics approaches have been touted as a valuable asset in achieving the ambitious goal of understanding user behavior and being able to develop intelligent online systems, which can positively influence people’s food choices.

At this talk you will hear about:
  • data science approaches to understand, predict and potentially change food decision making in an online context,
  • what extent online food interactions can be linked to real-world health issues such as obesity on a large-scale,
  • how people upload, bookmark or rate online recipes in large online food communities
  • and how contextual factors and biases such as seasonality, temporality, social context or presentation of recipes have an impact on popularity and how they are perceived.
With this background we can model and predict the users’ online food choices and attempt to nudge people towards food choices.

Christopher Trattner, a new ACM Distinguished Speaker, is a Full Professor at the University of Bergen, Norway, and Center Director of the Research Centre for Responsible Media Technology & Innovation - SFI MediaFutures. He is a founder of the DARS research group at UiB and and a Research Professor at one of Norway's largest research institutions and he is an Lecturer at MODUL University Vienna.

He received his PhD (with distinction) in Computer Science and Telematics from Graz University of Technology (Austria). He is an ACM Senior Member and has had research fellowships throughout Europe and the United States in academia and industry including Yahoo and CWI Amsterdam.

His research focuses on Behavioral Data Analytics and Recommender Systems. His work has been published over 100 scientific articles in top venues about my work including NATURE Sustainability, JASIST, EPJ Data Science, UMUAI, WWW, AAAI ICWSM or ACM SIGIR.

In addition to writing he has been a chair or organizer of a number of workshops and conferences including ACM RecSys in 2018 - 2020 and ACM SIGIR 2020 - 2021. He is also a member of the editorial board of Elsevier's journal on Online Social Networks and Media, the Open Access Journal Future Internet, Frontiers in Big Data, Springer's Journal of Intelligent Information Systems, and AI and Ethics.

As an instructor, since 2009, he has taught over 2000 students in Austria and Norway, in over 35 courses on BSc, MSc, MBA and PhD level about ICT, and I supervised over 35 students on their Master or PhD thesis.
