CCC Seminar by Jussara M. Almeida, Full Professor of Computer Science at the University of Minas Gerais, Brazil.
Abstract:
This talk examines how information spreads, clusters, and targets specific audiences across social media platforms. Drawing on three empirical studies, I analyze (i) the structure and discourse of misogynistic communities in Brazil, (ii) content directed at children on Instagram, and (iii) the emergence and alignment of political narratives in large-scale Telegram conversations during the 2024 U.S. elections. Together, these findings highlight relevant patterns underlying information diffusion across platforms and raise important questions about exposure, influence, and the amplification of targeted content in online ecosystems.

CCC Seminar by Virginia Ramón-Ferrer, PhD student and researcher in the Ontology Engineering Group from the Artificial Intelligence (AI) Department at the Universidad Politécnica de Madrid.
Abstract:
The presentation introduces the research activities of the Ontology Engineering Group, outlining its core areas (ontologies, knowledge graphs, NLP/NLG, and open science) and focusing on work in multilingual methods. In particular, it presents contributions on bridging structured data and text through data-to-text generation, multilingual benchmarks (such as Spanish WebNLG), and studies on multilingual and code-switched information retrieval, aiming to support more inclusive AI across languages.
Short Bio:
Virginia Ramón-Ferrer is a PhD student and researcher in the Ontology Engineering Group from the Artificial Intelligence (AI) Department at the Universidad Politécnica de Madrid, with a background in Computer Engineering, specifically in Computer Vision (CV) and Natural Language Processing (NLP). Her current work focuses on multilingual NLP, with an emphasis on multilingual data-to-text generation and Information Retrieval (IR), specifically in the intersection of structured data and text for IR, exploring how structured representations can better support retrieval and generation in multilingual settings.
