Teeuwen, R.F.L. (author), Milias, V. (author), Bozzon, A. (author), Psyllidis, A. (author)The study of urban greenspaces typically relies on three types of data: people’s subjective perceptions collected via questionnaires, vegetation indices derived from satellite imagery, such as the Normalized Difference Vegetation Index (NDVI), and Land Use or Land Cover maps, such as OpenStreetMap (OSM). Data on people’s perceptions are...journal article 2024

(author), Pera, M.S. (author)Web search has evolved into a platform people rely on for opinion formation on debated topics. Yet, pursuing this search intent can carry serious consequences for individuals and society and involves a high risk of biases. We argue that web search can and should empower users to form opinions responsibly and that the information retrieval...conference paper 2024

(author)High-quality data plays a vital role in developing reliable image classification models. Despite that, what makes an image difficult to classify remains an unstudied topic. This paper provides a first-of-its-kind, model-agnostic characterization of image atypicality based on human understanding. We consider the setting of image classification...conference paper 2023

Li, Z. (author), Sun, W. (author), Hai, R. (author), Bozzon, A. (author), Katsifodimos, A (author)The proliferation of pre-trained ML models in public Web-based model zoos facilitates the engineering of ML pipelines to address complex inference queries over datasets and streams of unstructured content. Constructing optimal plan for a query is hard, especially when constraints (e.g. accuracy or execution time) must be taken into consideration...conference paper 2023

Li, Z. (author), Hai, R. (author), Katsifodimos, A (author), Bozzon, A. (author)Machine learning (ML) researchers and practitioners are building repositories of pre-trained models, called model zoos. These model zoos contain metadata that detail various properties of the ML models and datasets, which are useful for reporting, auditing, reproducibility, and interpretability. Unfortunately, the existing metadata...conference paper 2023

van Beek, E. (author), Giaccardi, Elisa (author), Boess, S.U. (author), Bozzon, A. (author)Automated and connected technologies are increasingly present in everyday life. The concept of co-performance offers a new perspective on artificial agency by understanding artifacts as capable of performing everyday practices next to people. In this pictorial we adopt a lens informed by co-performance, and propose the visual vocabulary of the...conference paper 2023

van Beek, E. (author), Giaccardi, Elisa (author), Boess, S.U. (author), Bozzon, A. (author)By 2027 more than 530 M homes will likely adopt at least one type of automated system. This means that a growing number of residents will be living with automated technology in the home, everyday. But living with smart homes is full of conflicts between what residents find appropriate and what technology does instead. Previous research,...journal article 2023

Lessons Learned from Designing and Evaluating CLAICA: A Continuously Learning AI Cognitive AssistantKernan Freire, S. (author), Niforatos, E. (author), Wang, C.W. (author), Ruiz Arenas, S. (author), Foosherian, Mina (author), Wellsandt, Stefan (author), Bozzon, A. (author)Learning to operate a complex system, such as an agile production line, can be a daunting task. The high variability in products and frequent reconfigurations make it difficult to keep documentation up-to-date and share new knowledge amongst factory workers. We introduce CLAICA, a Continuously Learning AI Cognitive Assistant that supports...conference paper 2023

Mesbah, Sepideh (author), Arous, Ines (author), Yang, J. (author), Bozzon, A. (author)Evaluating design ideas is necessary to predict their success and assess their impact early on in the process. Existing methods rely either on metrics computed by systems that are effective but subject to errors and bias, or experts' ratings, which are accurate but expensive and long to collect. Crowdsourcing offers a compelling way to...conference paper 2023

As chatbots are being widely deployed in various empathic contexts (e.g., revealing sensitive personal information or facilitating charity donations), how to design...conference paper 2023
