Conference – Department of Informatics – DDIS https://www.uzh.ch/blog/ifi-ddis Dynamic and Distributed Information Systems Group Tue, 21 Feb 2023 13:31:29 +0000 en-US hourly 1 https://wordpress.org/?v=6.8.2 New Paper in AAAI ’23 https://www.uzh.ch/blog/ifi-ddis/2023/02/21/new-paper-in-aaai-23/ Tue, 21 Feb 2023 13:30:34 +0000 https://www.uzh.ch/blog/ifi-ddis/?p=804

A paper based on controllable models for simplifying medical text, co-authored by our colleague Rosni Kottekulam Vasu and external collaborators, was accepted at the 37th AAAI Conference on Artificial Intelligence! The paper is titled “Med-EASi: Finely Annotated Dataset and Models for Controllable Simplification of Medical Texts” and was jointly conducted with Chandrayee Basu, Michihiro Yasunaga from Stanford University, and Qian Yang from Cornell University.

The paper’s vision is an interactive automatic medical text simplification system, which can enable medical practitioners and patients to simplify the contents of a text or conversation selectively and have controllability over the type of desired textual transformations.

Rosni presented the work at AAAI, orally and on a poster and was accepted to the 2023 AAAI student scholarship and volunteer program. Congratulations!

Award for Paper Based on Student Thesis https://www.uzh.ch/blog/ifi-ddis/2023/01/25/award-for-paper-based-on-student-thesis/ Wed, 25 Jan 2023 10:32:04 +0000 https://www.uzh.ch/blog/ifi-ddis/?p=797

In his Bachelor Thesis, Viktor Lakic investigated the decay happening in datasets when the resources that Web-URLs point to become unavailable. This Link-Rot can cause problems for reproducibility, as datasets can shrink over time, potentially changing the outcome of experiments which use them. A paper based on the data that Viktor collected in his thesis, co-authored by Luca Rossetto and Abraham Bernstein, was recently presented at the 2023 International Conference on Multimedia Modeling in the Special Session on ‘Multimedia Datasets for Repeatable Experimentation’. The paper was awarded the ‘Best Special Session Paper Award’, honoring the best contribution across all special sessions of the conference. Congratulations!

Paper “Capable but Amoral? Comparing AI and Human Expert Collaboration in Ethical Decision Making” wins Honorable Mention at CHI 2022 https://www.uzh.ch/blog/ifi-ddis/2022/05/02/paper-wins-honorable-mention-at-chi-2022/ Mon, 02 May 2022 13:55:05 +0000 https://www.uzh.ch/blog/ifi-ddis/?p=748 The paper “Capable but Amoral? Comparing AI and Human Expert Collaboration in Ethical Decision Making” by Suzanne Tolmeijer, Markus Christen, Serhiy Kandul, Markus Kneer, and Abraham Bernstein wins an honorable mention at CHI 2022, which takes place this week.

The paper, which looks into how the kind of expert giving the advice — i.e., a human or an AI advisor — influences trust, perceived responsibility, and reliance.

For more information about the paper, please check it out in our on-line library, over at the ACM Digital Library, and the video presentation prepared by Suzanne.

Honorable Mention Award

For your convenience you can also find the abstract right here:

While artificial intelligence (AI) is increasingly applied for decision-making processes, ethical decisions pose challenges for AI applications. Given that humans cannot always agree on the right thing to do, how would ethical decision-making by AI systems be perceived and how would responsibility be ascribed in human-AI collaboration? In this study, we investigate how the expert type (human vs. AI) and level of expert autonomy (adviser vs. decider) influence trust, perceived responsibility, and reliance. We find that participants consider humans to be more morally trustworthy but less capable than their AI equivalent. This shows in participants’ reliance on AI: AI recommendations and decisions are accepted more often than the human expert’s. However, AI team experts are perceived to be less responsible than humans, while programmers and sellers of AI systems are deemed partially responsible instead.

DDIS at ISWC’20 https://www.uzh.ch/blog/ifi-ddis/2020/11/10/ddis-at-iswc20/ Tue, 10 Nov 2020 15:13:35 +0000 http://www.uzh.ch/blog/ifi-ddis/?p=648 Last week, our colleague Romana Pernischova presented her paper titled ‘ChImp: Visualizing Ontology Changes and their Impact in Protégé’ at the workshop VOILA, colocated with ISWC 2020. Together with Mirko Serbak, Daniele Dell’Aglio, and Abraham Bernstein, she looked at the needs of ontology engineers and created Protege plugin ChImp to help visualize changes and their impact while editing ontologies. Because of COVID-19, the conference took place online. Luckily, her presentation was still a success and well received. The paper can be found here.

At the same conference, a group of DDIS members also presented a demo of a graph-based retrieval system for lifelogs. ‘LifeGraph’ was developed in the context of an international evaluation campaign which, due to some changes and delays caused by the pandemic, was held online only a week before ISWC. During the demo, conference attendees could get an impression of how such a graph exploration-based approach could be used to find particular events from the life of a lifelogger. The demo was nominated for ‘Best Demo’. More information on the inner workings of that approach can be found in the paper, authored by Luca Rossetto, Matthias Baumgartner, Narges Ashena, Florian Ruosch, Romana Pernisch, and Abraham Bernstein.

Human Robot Interaction 2020 https://www.uzh.ch/blog/ifi-ddis/2020/05/04/human-robot-interaction-2020/ Mon, 04 May 2020 15:48:25 +0000 http://www.uzh.ch/blog/ifi-ddis/?p=616 During 24th to the 26th of March 2020, the Human Robot Interaction 2020 was supposed to take place in Cambridge, UK. Due to the recent COVID-19 pandemic, the conference was canceled and paper presentations happened online. Our colleague Suzanne Tolmeijer and her coauthors got their paper accepted called ‘Taxonomy of Trust-Relevant Failures and Mitigation Strategies‘. The presentation of the paper can be found here. The paper received an honorable mention.

In the paper, Suzanne and team develop a taxonomy to categorize HRI failure types and their impact on trust. A risk score is introduced, as well as possible mitigation strategies to handle trust breaks of the user in a robotic system. The collaboration for this paper was a result of a workshop at Schloss Dagstuhl on ‘Ethics and Trust: Principles, Verification and Validation‘.

The Web Conference 2020 https://www.uzh.ch/blog/ifi-ddis/2020/05/04/the-web-conference-2020/ Mon, 04 May 2020 15:29:46 +0000 http://www.uzh.ch/blog/ifi-ddis/?p=613 The Web Conference, the leading scientific forum on the web and related technologies, ran from April 20th to April 24th. Initially planned to be held in Taiwan, the conference moved to an online setting due to the COVID-19 pandemic. In this unusual setting, DDIS presented a study on differentially-private stream processing for the semantic web. Daniele Dell’Aglio and Abraham Bernstein tackled the problem of continuous publication of statistics extracted by data streams containing sensitive data by proposing a query language, SihlQL, and a novel algorithm, the bin removal mechanism. SihlQL is built on a fragment of SPARQL compatible with differential privacy, while the bin removal mechanism protects users behaving differently from the majority of the populations.

More information about this study is available in the article here and in the presentation that Daniele gave at the conference can be found by clicking the image below.

Finally, users interested in trying out SihlQL can find SihlMill, a SihlQL engine here.

This study is partially supported by the Swiss National Science Foundation under contract number #407550_167177 NFP 75‘s project Privacy-preserving, stream analytics for non-computer scientists.

DDIS @ Versus Virus https://www.uzh.ch/blog/ifi-ddis/2020/04/09/ddis-versus-virus/ Thu, 09 Apr 2020 08:17:10 +0000 http://www.uzh.ch/blog/ifi-ddis/?p=607 Last weekend, from April 3 to April 5, Versus Virus an online-hackathon took place to address challenges imposed on Switzerland and its inhabitants by the ongoing crisis caused by Covid-19. Over the course of 48 hours, more than 4600 people contributed to solutions in 263 teams. Among the participants were also two members of DDIS, Rosni Kottekulam Vasu and Florian Ruosch. Independently, they both worked on their respective team’s projects.

Crowds vs Covid

Rosni was part of a team that tackled the challenge that the global research community is overwhelmed with the resources of over 47,000 scholarly articles related to COVID-19, SARS-CoV-2, and related coronavirus. The overloading for scientific and lay people about COVID-19 makes it very difficult to select the right information at the right time. In this context, they developed a pipeline, which can take high volumes of information (either scientific publications or social media), filter it by first feeding it through machine learning algorithms, and then use crowdsourcing to further refine the selection and tagging. This information can then be used to inform policy makers or subject experts in a timely manner.

You can find more information about the project at the following locations:

KurzarbeitGoesDigital

Florian helped developing a platform to digitalize, simplify, and accelerate the application process for short-time work (Kurzarbeit). Employers can digitally file the application according to official governmental and cantonal guidelines. The digitalized solution may be used swiss-wide and considers cantonal differences. Furthermore, it allows to make real-time analyses based on filed applications per canton or aggregated for the whole country and visualize the results. This project even made it into the set of highlights in the category “Economic Impact”.
