22.09.2022 – Bias by Design: How Digital Technology Can Fail its Diverse Users

Speaker:  Prof. Dr. Katharina Reinecke

Host: Prof. Abraham Bernstein, PhD

Abstract

From social media to conversational AI, digital technology has become a mainstay in the lives of many people around the world. Many of these inventions have been made in large technology centers, like Silicon Valley, that are inherently biased towards the views and experiences of product designers and developers who do not reflect a broad demographic in terms of age, education levels, culture, race, and physical abilities. 

In this talk, I will show how unconscious bias in the design of digital technology can systematically disadvantage specific groups of people. Specifically, I will present my lab’s prior work on diverse users’ experiences with digital technologies—ranging from websites and online communities to security & privacy interfaces and conversational AI—outlining how a lack of knowledge about diverse people can result in technology that is useful for some, but not all users. I will also present two approaches we have developed for recognizing biases in digital technology design: (i) Studying how diverse populations interact with technology using our volunteer-based Lab in the Wild platform and (ii) anticipating biases based on historical data on the unintended consequences of technology using our SpecTechle platform.
 

Bio

Katharina Reinecke is an Associate Professor at the Paul G. Allen School of Computer Science & Engineering at the University of Washington where she researchers and teaches human-computer interaction and computing ethics. Her research explores how people's interaction with digital technology varies depending on their cultural, geographic, or demographic background and how technology can be biased against people who are unlike the small groups of people that created it. Her lab has developed a number of approaches and systems that make technology better suitable for diverse user groups and that can help designers and developers anticipate unintended consequences of technology. 

Katharina is a co-founder of Lab in the Wild, a virtual lab for conducting large-scale behavioral studies with diverse participants, and of Augury Design Inc., a startup that predicts the success of website designs based on Lab in the Wild data. Katharina received a PhD in Computer Science from the University of Zurich and was a postdoctoral fellow at Harvard University. Prior to coming to the University of Washington, she was an Assistant Professor in the School of Information at the University of Michigan. Her lab is currently supported by the NSF, Google, Microsoft, Adobe, the Wikimedia Foundation, and Facebook.
 

 

27.10.2022 – From Textual Data to Open Research Data Queryable by References

Speaker:  Dr. Sepideh Alassi

Host: Prof. Dr. Martin Volk

Abstract

Humanities textual data is full of references to persons and locations given in various languages. Researchers want to perform queries to retrieve data, in which a certain place or a person is mentioned, irrespective of the language of the text. 
In this talk, I will present how we automatically extract named entities (geolocation information and person references) from textual data and homogenize and store them as Linked Open Data (LOD) with unique identifiers such as the GeoName ID and the GND (Gemeinsame Normdatei) number. Then the plain references in the text are substituted with standoff links to the corresponding RDF resources and the textual document is stored in RDF format. This enables humanities scholars to perform advanced SPARQL queries to collect textual resources containing specific references regardless of the language of the text. Furthermore, I will present how we apply Natural Language Processing (NLP) to establish connections between the named entities in the text to add more semantic information to the knowledge graph.

Bio

Dr. Sepideh Alassi is a postdoctoral research associate and a lecturer at the Digital Humanities Lab (DHLab), University of Basel. Her background is in digital humanities, computer science, mathematics, and the history of science. She earned her PhD in 2020 in the field of digital humanities and is one of the main developers of Knora (recently renamed DSP-API), Switzerland's flagship RDF-based system for editing, storing, searching, and reusing humanities research data. Her main focus in the field of digital humanities is on applying linked open data (LOD) and semantic web technologies to humanities data creating a knowledge graph that can be efficiently analyzed and queried.

 

03.11.2022 – Volume Rendering in VR for Medicine

Speaker:  Prof. Dr. Philippe C. Cattin

Host: Prof. Dr. Renato Pajarola

Abstract

The amount of imaging data in the medical field (CT, MR, and others) is growing at a rapid pace. With each new generation of imaging device, the images get even higher spatial resolutions. However, more data does not automatically lead to better diagnoses. While the flood of data continues to grow, comparatively little research is being done on how to make this data more tangible. Philippe Cattin develops a virtual reality system to solve this task. In this talk, he will present this system and discuss the challenges when employing Volume Rendering to visualize patient data. These challenges are even more pronounced when showing volume-rendered images in a virtual reality environment.

Bio

Philippe Cattin was born in Switzerland in 1967. He received his B.Sc. degree from the University of Applied Science in Brugg/Windisch in 1991.

He is also the founder of three spin-off companies and licensed his patents and software to medical device companies.

 

10.11.2022 – Interacting with AI

Speaker:  Prof. Dr. Michael Sedlmair

Host: Prof. Dr. Jürgen Bernard

Abstract

In recent years, there has been a strong focus on fully autonomous AI technologies. While full automatization is easy to communicate in the media, the contemporary rhetoric seems to forget that most problems will continue to necessitate meaningful interactions between humans and machines. Along the life cycle of  AI, there are many steps for which humans are needed in the loop: humans need to be able to understand the underlying data, explain AI models, or even cooperate with AI to excel at tasks such as decision making and music composition. Our work focuses exactly on these data, model, and AI interfaces. To that end, we develop and study techniques that combine approaches from human-computer interaction, data visualization, and mixed reality. In the talk, we will look at different examples of such human-data and human-AI interfaces, and think about when they are needed and how to properly build them.

Bio

Michael Sedlmair is a professor at the University of Stuttgart and leads the research group for Visualization and Virtual/Augmented Reality there. He received his Ph.D. degree in Computer Science from the University of Munich, Germany, in 2010.

His research interests focus on visual and interactive machine learning, perceptual modeling for visualization, immersive analytics and situated visualization, novel interaction technologies, as well as the methodological and theoretical foundations underlying them.

 

17.11.2022 – AI and bureaucratic decision-making: a new layer of opacity

Speaker:  Prof. Dr. Antonio Cordella

Host: Prof. Dr. Gerhard Schwabe and Dr. Liudmila Zavolokina

Abstract

This talk offers an in-depth analysis and explanation of the reasons why AI cannot solve the problems of transparency and accountability of public administration bureaucracies. The talk offers an innovative theoretical framework for the analysis of AI: the theory of functional simplification and closure. Moreover, the talk contributes providing an innovative way to study AI in the context of public sector bureaucracies, shedding lights on the different impacts of AI on the transparency and accountability of public administration bureaucracies using Mintzberg’s taxonomy of machinery and professional bureaucracy (Mintzberg, 1983). To support the theoretical argument the tlak analyses the well-known public sector AI case of COMPAS, the algorithmic system used to assess offenders’ risk score in US Judiciary – to illustrate how and why AI makes opaquer public bureaucracies decision-making.

01.12.2022 – What can we learn from Squid Game, Game of Thrones, or Breaking Bad to Lower the Socioeconomic Inequalities in Health?

Speaker:  Prof. Dr. Tobias Kowatsch

Host: Prof. Dr. Gerhard Schwabe

Abstract

Non-communicable diseases (NCDs) impose enormous health burdens on individuals and lead to substantial economic challenges. Known risk factors relate primarily to a lifestyle characterized by tobacco and excessive alcohol consumption, physical inactivity, or an unbalanced diet. This lifestyle can lead to obesity, hypertension, and other cardiovascular and neurodegenerative diseases. Unfortunately, individuals with lower socioeconomic status (SES) are substantially more affected by NCDs. These individuals are also underrepresented in clinical and non-clinical trials. As a result, health interventions are potentially only effective for individuals with higher SES and do not address those most in need. Therefore, it is essential to understand how to reach and engage individuals with lower SES. In this talk, I will discuss what we can learn from the most successful TV shows to “hijack” the comfort zones of vulnerable individuals and design digital health interventions that may lower the socioeconomic inequalities in health.
