Keynote #1: Katrina Liggett
Data Degrades with Use
Calendar

Talk Title: Data Degrades with Use

Abstract: We often treat data as an infinitely reusable resource: a single dataset can support many analyses, train multiple models, and be shared widely without apparent cost. This talk argues that in important ways, data is not endlessly reusable. Instead, in certain contexts, data behaves like a consumable resource that degrades with use. The clearest example arises in the presence of privacy concerns. Fundamental results show that any informative public analysis of personal data inevitably leaks some information about the underlying individuals, and that these privacy losses accumulate across repeated uses of the same or overlapping datasets. If some level of privacy is to be preserved, this imposes intrinsic limits on how many times data can be used. In joint work under submission, we connect this perspective to the mosaic effect from legal scholarship, arguing that privacy risks arise not only from combining data pieces, but also from combining seemingly innocuous data uses. Data can also degrade with use even when privacy is not at stake. A line of work on adaptive data analysis shows that repeatedly querying the same dataset can lead to overfitting: results that appear valid on the dataset but fail to generalize to the underlying distribution, even when the dataset is very large. Recognizing data degradation opens a range of research directions, including systems for tracking and budgeting data use, algorithmic techniques to mitigate degradation, the role of synthetic data and data curators, and new models of non-worst-case adaptive computation.

Bio: Katrina Ligett is a Professor in the School of Computer Science and Engineering at The Hebrew University of Jerusalem, where she is also the director of the interdisciplinary Federmann Center for the Study of Rationality. Before joining Hebrew University, she was faculty in computer science and economics at Caltech.

Building AI-Driven Web Experiences at Scale
Calendar

Talk Title: Building AI-Driven Web Experiences at Scale

Abstract: AI is no longer just a component of Web systems; it is increasingly shaping the experiences users have online. From search and recommendation to conversational and generative interfaces, AI is redefining how people interact with content at Web scale. In this keynote, I reflect on how recent advances in AI, including deep learning and generative models, are reshaping the design space of Web technologies. Drawing on insights from developing AI-driven systems at Spotify, I discuss how search and recommendation are evolving into interactive, intent-aware experiences that support exploration and discovery. The talk highlights emerging system paradigms and research questions around building such experiences at scale, and reflects on the implications for the design of future Web systems and interactions.

Bio: Mounia Lalmas is Senior Director of Research at Spotify, where she leads Tech Research in Personalisation, focusing on search, recommendation, and discovery systems at scale. Her work spans information retrieval, recommender systems, user engagement, and the application of modern AI techniques to large-scale online platforms. She previously held senior roles including Director of Research at Yahoo and Professor of Information Retrieval at Queen Mary University of London. Mounia is an Honorary Professor at University College London and a Distinguished Research Fellow at the University of Amsterdam. She has co-chaired major conferences including SIGIR, WWW, WSDM, and CIKM, and authored over 260 publications.

(Everything You Never Knew You Needed To Know About) Rank-Biased Measurement For Web Search
Calendar

Talk Title: (Everything You Never Knew You Needed To Know About) Rank-Biased Measurement For Web Search

Abstract: In information retrieval and web search we measure how good search engines are at ordering answers to user queries, how close two ranked lists are to each other, how good LLMs are at re-ranking sets of candidate documents, and how close generated answer sentences are to the ideal output. This talk begins by motivating the top-weighted measurements that arise when ordered sequences are involved, including reviewing the rank-biased precision and rank-biased overlap measurements proposed in 2008 and 2010. The second part then presents recent work unifying the two previous rank-biased approaches as elements in a larger framework that exposes a third rank-biased measurement, rank-biased recall. Finally, in the third part, new ways in which the degree of top-weighting bias can be controlled are described, allowing practitioners and researchers to better define their measurement goals and more precisely target their experiments.

Bio: Professor Alistair Moffat is now in his 40th year as a faculty member at the University of Melbourne. Early work included coauthorship of the book "Managing Gigabytes: Compressing and Indexing Documents and Images" (1994, 1999), and development of innovative mechanisms for implementing ranked queries via compressed inverted indexes. Most recently Alistair has been focused on IR evaluation, including models for user query formulation and result perusal, and rank-biased measurement. Alistair was inducted into the SIGIR Academy in 2021, and recently became a Fellow of the ACM for his contributions to the implementation and evaluation of search systems.

Keynote talk #4: Pascale Fung
Towards AI That Understands the Human World
Calendar

Talk Title: Towards AI That Understands the Human World

Abstract: AI has reached a turning point. Systems can now perceive, generate, and act in language and image across digital platforms at unprecedented scale. Yet as AI moves from tools to collaborators—embedded in decision-making, institutions, and everyday life—a new requirement becomes unavoidable: AI must understand the world the way humans inhabit it. This talk introduces Cognitive World Modeling as the next phase of AI development. It unifies physical world modeling—time, space, causality, action—with mental world modeling—goals, beliefs, intentions, emotions, and social norms—into a single, persistent representation of reality as experienced by humans. Together, these models allow AI systems not only to predict outcomes, but to reason about meaning, context, and consequence. Alignment and trust emerge not as post hoc constraints, but as properties of systems that maintain accurate, evolving models of both the external world and the humans within it.

Bio: Pascale Fung's long-term research background is in multimodal interactive systems including audio, speech, text and video. She is the Co-founder and Chief Research & Innovation Officer at AMI Labs. She was previously the Senior Director of AI Research at Meta-FAIR, leading research on embodied AI agents. She is also a Chair Professor of ECE at The Hong Kong University of Science & Technology (HKUST). She is a Fellow of the ACL, AAAI, IEEE, and ISCA for her significant contribution to human-machine interactions.
