The European Association for Data Science organises a
Summer School on Data Science for Social Media
Monday July 19th to Thursday July 22nd 2021 in Kirchberg, Luxembourg.
Social media is ubiquitous in our modern world. Its ubiquity makes it an attractive object for study in various fields. Applications start with social science, over economics, computer science and go even to health science and disaster control.
On the other hand the validity of such data has been repeatedly brought into question and, given the rich portfolio of approaches and ideas this field is certainly in danger of overpromising.
Regardless of these concerns, social media analysis will be an important method in future research in many different fields. Discussing it potentials and limitations, transfer of methods and ideas, is what this summer school is about.
The Summer School is primarily aimed at advanced PhD students, postdoctoral and early-career researchers with an interest and basic grounding in data science, machine learning, and/or statistics.

The summer school will be preceded by a public event on Monday, July 19th starting 12:30 p.m.
At the heart of the public event is the Sabine-Krolak-Schwerdt-Lecture, in memoriam of EuADS founding president.
We are delighted to announce that Alexander Pentland from MIT Media Lab will deliver this year’s public lecture.
The public event will be followed by a welcome reception.
Understanding Human Network Behavior: Ideas for reforming social media
Alexander Pentland (MIT Media Lab)
Recent large-scale experiments have given us quantitative models of human decision making that allow predictive modeling of crowd behavior across many situations. These models suggest ways of reforming social media that go beyond suppression of fake news and bots, and have proven track records in other digital platforms. Two innovations in particular appear to be critical: unique, reliable identity, and use-specific reputation mechanisms.Speaker's Website

Static and Dynamic Mapping Method for Uncovering Competitive Positions
Prof Dr Bernd Skiera (Goethe University Frankfurt, Germany)
A market map provides managers with a static snapshot of the competitive positions of a market’s participants (such as products or brands). Today, most markets are rather large (e.g., comprising hundreds of products so that a comprehensive visualization of competitive market structures can be cumbersome and complex. Yet, reduction of the analysis to smaller representative product sets can obscure important information. The first part of the workshop outlines (i) data sources to derive consideration sets of consumers that reflect competition between products and (ii) approaches (e.g., building upon social network analysis) that integrate these data into a modeling and mapping approach to visualize competition in large markets and to identify distinct submarkets.
Yet, as markets tend to be in flux, knowledge about the trajectories of competitive positions of market’s participant over time would be more informative than a static snapshot. In contrast to static snapshots, trajectories create a forward-looking perspective on competition, reveal whether positions are converging or diverging and help managers evaluate the impact of their positioning efforts. Although data for market structure analysis is increasingly available in high frequency (see part 1 of the workshop), extant mapping methods are exclusively static, and do not reveal market participants’ trajectories. Therefore, I focus in part 2 of the workshop on dynamic mapping method that generate a sequence of cohesive maps that enable market analysts to track the trajectories of competitive positions over time.Speaker's Website
The evolution of digital behavioral trace and survey data in social networks
Prof Dr Christoph Stadtfeld (ETH Zürich, Switzerland)
The increasing availability of digital behavioral trace (DBT) data promises novel social science studies that simultaneously scale up on a large number of study participants and zoom in on fine-grained individual behavioral actions. These data may, for example, stem from social media platforms, social sensor experiments, or wearable technologies such as smart phones or watches. DBT data offer a seemingly objective perspective on how people behave individually and socially – how they eat, sleep, travel, interact, socialise, and date. DBT network data often come in the form of relational events – time-stamped dyadic observations that can be represented as time-ordered edge lists. Several new models for the statistical analysis of relational events have been proposed over the past years. The first part of the course will cover the statistical analysis of DBT data with relational event models.
Studies that merely rely on DBT data have some obvious blind spots. Individual behavior is to a large extent based on how individuals perceive their environment, their relationships, and themselves. Such perception data can be well collected through traditional surveys. Survey data also have known challenges such as cognitive burdens, necessary time investments by participants, and measurement biases. Traditional social network data often stem from surveys and may represent who individuals perceive as friends, whom they like or dislike, and whom they trust. Dynamic network data collected through surveys can, for example, be statistically analysed with stochastic actor-oriented models. These models will be briefly discussed in the second part of the course.Speaker's Website

Social media metrics: definitions and applications
Dr Zohreh Zahedi (University of Leiden, Persian Gulf University)
Social media metrics (altmetrics) refers to metrics derived from social media platforms (such as Facebook, Twitter, Wikipedia, mainstream news websites, etc.). These metrics offer possibility of studying the relations and interactions between social media users, scholarly contents, and different actors. Altmetrics data aggregators provide access to social media metrics differ in terms of methodological choices in collecting, updating, tracking, and reporting metrics. This course focuses on defining and interpreting social media metrics, data possibilities and challenges, social media metrics data analysis and their uses and applications.Speaker's Website
Learning user preferences from social media data
Prof Dr Eyke Hüllermeier (LMU Munich)
The topic of “preferences” has attracted increasing attention in artificial intelligence and machine learning in the recent past, where it has emerged as an interdisciplinary research field with close connections to operations research, social choice, and the decision sciences. Roughly speaking, preference learning is about methods for learning preference models from explicit or implicit information about the preferences of an individual or a group of individuals, and the use of such models for predicting preferences in new situations. Approaches relevant to this field range from learning special types of preference models, such ranking functions, to collaborative filtering techniques for recommender systems. The goal of this talk is to provide a brief introduction to the field of preference learning and, moreover, to elaborate on the use of preference learning in the context of social media, notably for learning user preferences from social media data.Speaker's Website

Responsible social-media based collective intelligence
Prof Dr Eirini Ntoutsi (FU Berlin, Germany)
The Web offers enormous benefits for information sharing, collective organization and distributed activity with great impact in all areas of our lives. However, along with the benefits come also negative consequences like hate speech, fake news, surveillance, etc. Ambivalences lie at the heart of the Web and we must deal responsibly with these ambivalences to amplify the benefits and counter the negative effects. Towards this direction, as data scientists we should work towards responsible analysis of data collected via the Web. While we all agree that the huge amounts of data generated in the Web offer paramount opportunities for data-science related applications and are the pre-condition for the success of modern machine learning methods, we cannot ignore the fact that data collection comes with assumptions, and moreover, further assumptions are made during the analysis pipeline which of course have great impact on the extracted knowledge. In this talk, we will focus on such assumptions, including data sampling, redundancies, proxy-labeling, temporality and bias), their effect on the learning process and how to build effective models under such assumptions.Speaker's Website

Many activities have gone digital in the past month to an extend considered impossible a year ago. Some activities have, on the other hand, proven difficult to digitalise. Effective networking and informal exchange of ideas, a central part of the format of a summer school, is one such activity.
For that reason we are aiming to conduct the summer school as an in-person event. We will constantly monitor the current development, travel restrictions and recommendations. We are currently optimistic that events such as the summer school will be possible in July 2021. However, we point out that it is still possible that we will need to postpone the summer school to a later date. We will announce such a rescheduling here. We ask all attendees to prepare for such occurrences, e.g. by travel cancellation insurances and similar. EuADS can unfortunately not cover cancellations fees or other expenses caused by an eventual cancellation of the event.
We consider it important that the speakers of the summer school are on the venue side and available to questions and discussion e.g. in coffee breaks and similar. Should some speakers, however, be unable to travel to Luxembourg, we will make every effort for a remote talk to the plenum on the conference venue.
