Research on Digital Trace Data: Collecting online data, ethical perspectives and biases.

Course Description

In this class students will learn about designing research using digital trace data. We will walk though tools and methods for collecting data online, ethical and legal considerations when carrying out such research, and finally quality assessment of the collected data with particular focus on potential biases. Students will receive an overview of important lines of research in computational social science and solve practical exercises around data collection.

Instructor Prof. Dr. Aniko Hannak
Short Bio Aniko is an assistant professor at the Vienna University of Economics and Business, and faculty member of the Complexity Science Hub.
She received her PhD from the College of Computer & Information Science at Northeastern University, where she was part of the Lazer Lab and the Algorithmic Auditing Group. Aniko’s main interest lies in computational social sciences, more specifically she is focusing on the co-evolution of online systems and their users. Broadly, her work investigates a variety of content serving websites such as search engines, online stores, job search sites, or freelance marketplaces and uncovers potential negative consequences of the big data algorithms that these websites deploy.

TUE

Text Mining with Neural Embeddings

Course Description

Text mining is the task of extracting structured information from unstructured text, for example discovering events, detecting sentiment or generating tet summaries. In this course we will give a general description of various text mining methods and will focus on automatically extracted vector representations (or embeddings) as the main source of info of text analysis. We will cover various types of embeddings (words or sentences, fixed or contextualized), how they are learned and what their strengths and weaknesses are; we will then focus on practical tasks in text mining that can be tackled using neural embeddings: sentiment analysis, similarity matching, and text summarization.

The curriculum includes alternating theoretical lectures on the background of the introduced methodology as well as practice sessions where the participants can try the methods in practice. The main prerequisite for course participants is a strong background in computer science and mathematics, experinece in programming (especially Python) is also required.

Network Science and Machine Learning for High-Resolution Social networks

Course Description

Access to large-scale, fine-grained data on specific human behaviors is changing the way we study social systems and collective behaviors, stimulating the growth of interdisciplinary research domains like Computational Social Science and Network Science, and motivating the study of interesting problems in Computer Science. This course will focus on high-resolution social network data from digital platforms such as smartphones and wearables sensors, and on a variety of applied problems motivated by access to time-resolved relational data. The first part of the course will briefly review elementary notions of network science and supervised machine learning, and then provide an historical overview of low-dimensional vector space representations for nodes in networks, together with hands-on exercises with popular algorithms for node embedding. The second part of the course will focus on high-resolution social networks, illustrating the complex properties and rich structures found in empirical data, and providing an overview of relevant concepts and techniques from social network analysis and unsupervised machine learning. We will close with a second hands-on session based on real data collected by means of wearable sensors.

Data Analysis (am) \& Data Visualization (pm)

Morning

Inequalities in Social Networks

Course Description

Homophily can put minorities in social networks at a disadvantage by restricting their ability to establish links with people from a majority group. This can limit the overall visibility of minorities in the network, and create biases. In this talk, I will show how the visibility of minority groups in social networks is a function of (i) their relative group size and (ii) the presence or absence of homophilic behavior. In addition, the results show that perception biases can emerge in social networks with high homophily or high heterophily and unequal group sizes, and that these effects are highly related to the asymmetric nature of homophily in networks. This work presents a foundation for assessing the visibility of minority groups and corresponding perception biases in social networks in which homophilic or heterophilic behaviour is present. Overall, the talk will motivate and exemplify new research endeveaors on the intersection between computational and social sciences.

terms such as Visual Facilitation, Visual Recording, Graphic Facilitation, Sketchnoting or Graphic Recording it describes the way in which content can be documented and presented creatively. This workshop allows you to enter this exciting world of hand drawn visualization - whether analogue on the flip chart, digitally on the tablet or simply with any pen on a piece of paper. No prior knowledge needed! With a few colors, simple shapes and small tricks, you can improve your visualization techniques superior to many others.

Data Visualization Primer

Course Description

Visualizing data is a core activity in data science workflows. In this lecture we’ll look at the basics behind generating effective data visualizations: matching data types to visual channels; perceptual principles that motive design guidelines; and strategies for understanding *what* you want to visualize. We’ll also cover current research approaches for visualizing graphs and for conducting visualization design projects
