- Talk on "Learning from the People: Responsibly Encouraging Adoption of Contact Tracing Apps" by Elissa Redmiles (Max Planck Institute for Software Systems)
Talk on "Learning from the People: Responsibly Encouraging Adoption of Contact Tracing Apps" by Elissa Redmiles (Max Planck Institute for Software Systems) 1st June 2022 12:15 pm - 1:15 pm Abstract At the beginning of the pandemic contact tracing apps proliferated as a potential solution to scaling infection tracking and response. While significant focus was put on developing privacy protocols for these apps, relatively less attention was given to understanding why, and why not, users might adopt them. Yet, for these technological solutions to benefit public health, users must be willing to adopt these apps. In this talk I showcase the value of taking a descriptive ethics approach to setting best practices in this new domain. Descriptive ethics, introduced by the field of moral philosophy, determines best practices by learning directly from the user -- observing people’s preferences and inferring best practice from that behavior -- instead of exclusively relying on experts' normative decisions. This talk presents an empirically-validated framework of user's decision inputs to adopt COVID19 contact tracing apps, including app accuracy, privacy, benefits, and mobile costs. Using predictive models of users' likelihood to install COVID apps based on quantifications of these factors, I show how high the bar is for achieving adoption. I conclude by discussing a large-scale field study in which we put our survey and experimental results into practice to help the U.S. state of Louisiana advertise their COVID app and found differential results regarding the effect of privacy transparency when prosocial vs. individualist appeals were used to encourage app adoption. http://domino.mpi-inf.mpg.de/internet/events.nsf/0/F7DC84935733F248C12588440024305D See more details

- Talk on "Interpreting Studies: Approaching language usage from a remote corner of the universe" by Bart Defrancq Department of Translation, Interpreting and Communication, Ghent University
Talk on "Interpreting Studies: Approaching language usage from a remote corner of the universe" by Bart Defrancq Department of Translation, Interpreting and Communication, Ghent University 9th June 2022 4:15 pm - 5:15 pm Abstract: Language corpora have been crucial for the study of language usage and variation. Similarly, translation corpora have informed us about the specific language variety of translations, variously called translationese, the third code, interlanguage, etc. However, corpora of interpreting have comparatively contributed fairly little to the study of spoken varieties. I will review attempts that have been made and suggest some new avenues of research into the remote corners of the universe of constrained language.

- Talk on "Data Science Methods for the Analysis of Controversial SocialMedia Discussions" by Anna Christina de Carvalho Guimaraes (Max-Planck-Institut für Informatik - D5)
Talk on "Data Science Methods for the Analysis of Controversial SocialMedia Discussions" by Anna Christina de Carvalho Guimaraes (Max-Planck-Institut für Informatik - D5) 10th June 2022 1:00 pm - 2:00 pm Abstract: Social media communities like Reddit and Twitter allow users to express their views on topics of their interest, and to engage with other users who may share or oppose these views. This can lead to productive discussions towards a consensus, or to contended debates, where disagreements frequently arise. Prior work on such settings has primarily focused on identifying notable instances of antisocial behavior such as hate-speech and "trolling", which represent possible threats to the health of a community. These, however, are exceptionally severe phenomena, and do not encompass controversies stemming from user debates, differences of opinions, and off-topic content, all of which can naturally come up in a discussion without going so far as to compromise its development. This dissertation proposes a framework for the systematic analysis of social media discussions that take place in the presence of controversial themes, disagreements, and mixed opinions from participating users. We start by building a feature model to characterize adversarial discussions surrounding political campaigns on Twitter, with a focus on the factual and sentimental nature of their topics and the role played by different users involved. We then extend our approach to Reddit discussions, leveraging community feedback signals to define a new notion of controversy and to highlight conversational archetypes that arise from frequent and interesting interaction patterns. We use our feature model to build logistic regression classifiers that can predict future instances of controversy in Reddit communities centered on politics, world news, sports, and personal relationships. Finally, our model also provides the basis for a comparison of different communities in the health domain, where topics and activity vary considerably despite their shared overall focus. http://domino.mpi-inf.mpg.de/internet/events.nsf/0/E0A7A43223166D82C1258854003C5175 See more details

- PhD Defense Ben Wiederhake
PhD Defense Ben Wiederhake 14th June 2022 10:00 am - 11:00 am Abstract: In this talk you will learn about distributed systems, with a particular focus on graph problems and fault tolerance. Fault-tolerance in a microprocessor or even System-on-Chip can be improved by using a fault-tolerant pulse propagation design. The existing design TRIX achieves this goal by being a distributed system consisting of very simple nodes. We show that even in the typical mode of operation without faults, TRIX performs significantly better than a regular wire or clock tree: Statistical evaluation of our simulated experiments show that we achieve a skew with standard deviation of O(log log H), where H is the height of the TRIX grid. http://domino.mpi-inf.mpg.de/internet/events.nsf/0/535BF8690FE25F72C125883D004305D6 The distance-r generalization of classic graph problems can give us insights on how distance affects hardness of a problem. For the distance-r dominating set problem, we present both an algorithmic upper and unconditional lower bound for any graph class with certain high-girth and sparseness criteria. In particular, our algorithm achieves a O(r · f(r))-approximation in time O(r), where f is the expansion function, which correlates with density. For constant r, this implies a constant approximation factor, in constant time. We also show that no algorithm can achieve a (2r + 1 − δ)-approximation for any δ > 0 in time O(r), not even on the class of cycles of girth at least 5r. Furthermore, we extend the algorithm to related graph cover problems and even to a different execution model. Furthermore, we investigate the problem of packet forwarding, which addresses the question of how and when best to forward packets in a distributed system. These packets are injected by an adversary. We build on the existing algorithm OED to handle more than a single destination. In particular, we show that buffers of size O(log n) are sufficient for this algorithm, in contrast to O(n) for the naive approach. See more details

- Talk on: "How contextual are contextual language models?" by Sebastian Schuster, Department of Linguistics and Center of Data Science, New York University
Talk on: "How contextual are contextual language models?" by Sebastian Schuster, Department of Linguistics and Center of Data Science, New York University 23rd June 2022 4:15 pm - 5:15 pm The interpretation of many sentences depends on context. This is particularly true for pragmatic interpretations, that is, interpretations that go beyond the literal meaning of sentences. For example, consider the sentence „The dog looks awfully happy.“ Out of context, its interpretation primarily concerns some dog’s emotional state. However, if this sentence is given as an answer to „What happened to the turkey?“, listeners will additionally infer that the dog likely ate the turkey. In this talk, I will present three studies that investigate to what extent recently proposed contextual language models are able to take context into account when drawing different pragmatic inferences. I will focus on context-dependent scalar inferences (inferring that „some“ sometimes, but not always, means „some but not all“), presuppositions, and tracking of discourse entities, and explain to what extent models like BERT, DeBERTa, and GPT-3 can interpret context-sensitive sentences. If you would like to meet the speaker, please contact Vera Demberg: vera@coli.uni-saarland.de Location: The talk will be held in hybrid form in Conference Room 2.02, Building A2.2 & via Teams: ________________________________________________________________________________ Microsoft Teams-Besprechung Nehmen Sie von Ihrem Computer oder der mobilen App aus teil Klicken Sie hier, um an der Besprechung teilzunehmen Oder anrufen (nur Audio) +49 69 677765673,,823276136# Germany, Frankfurt am Main Telefonkonferenz-ID: 823 276 136# Lokale Nummer suchen | PIN zurücksetzen Weitere Infos | Besprechungsoptionen ________________________________________________________________________________ See more details

- Talk on "Lifted Edges as Connectivity Priors for Multicut and Disjoint Paths" by Andrea Hornakova (Max-Planck-Institut für Informatik - D2)
Talk on "Lifted Edges as Connectivity Priors for Multicut and Disjoint Paths" by Andrea Hornakova (Max-Planck-Institut für Informatik - D2) 29th June 2022 2:00 pm - 3:00 pm E 1.5, Room: 029 Abstract We study two graph decompositions problems and their representation by 0/1 labeling of edges. The first is multicut (MC) which represents decompositions of undirected graphs (clustering of nodes into connected components). The second is disjoint paths(DP) in directed acyclic graphs where the clusters correspond to node-disjoint paths. Our main interest is to study connectivity priors represented by so-called lifted edges in the two problems. We call the resulting problems lifted multicut (LMC) and lifted disjoint paths (LDP). Our study of lifted multicut concentrates on partial LMC represented by labeling of a subset of (lifted) edges.Given partial labeling, some NP-hard problems arise. The main focus of the talk is LDP problem. We prove that this problem is NP-hard and propose an optimal integer linear programming (ILP) solver. The solver uses linear inequalities that produce a high-quality LP relaxation. LDP is a convenient model for multiple object tracking(MOT) because DP naturally leads to trajectories of objects and lifted edges help to prevent id switches and re-identify persons. Our tracker using the optimal LDP solver was a leading tracker on three benchmarks of the MOT challenge MOT15/16/17, improving significantly overstate-of-the-art at the time of its publication. In order to solve even larger instances of a challenging dataset MOT20, we introduce an approximate LDP solver based on Lagrange decomposition. The new tracker achieved on all the four standard MOT benchmarks performance comparable or better than state-of-the-art methods (at the time of publication). http://domino.mpi-inf.mpg.de/internet/events.nsf/0/F9136DC0A78D3B12C12588680028F029 See more details
