    Enhanced phishing detection using multimodal data
    Knowledge-Based Systems

    hishing remains one of the most persistent cybersecurity threats, increasingly exploiting not only technical vulnerabilities but also human cognitive biases. Existing detection systems often rely on single-modality features and black-box models, which restrict both generalization and interpretability. This study presents an explainable multimodal framework that combines textual and technical cues, including message content, URL structure, and Principles of Persuasion, to capture both objective and subjective aspects of phishing.

    Análisis de emociones en torno a las comunidades de activistas en el contexto de las movilizaciones del \#8M2023 en México
    Revista Iberoamericana de Comunicación

    En este artículo se aborda el estudio de las emociones expresadas en los hasthtags producidos en torno a las movilizaciones feministas ocurridas el 8 de marzo de 2023 en México. Para realizar el análisis de datos correspondiente al #8M2023 en la red social X (antes Twitter) se utilizó la API de X para recolectar una muestra de 1301 publicaciones de 866 usuarios únicos. Se analizaron con base en la propuesta de Jasper (2012). El análisis permitió identificar nodos, comunidades y reivindicaciones vinculadas a emociones y la conexión generacional presente en las consignas.

    Machine learning framework for country image analysis
    Journal of Computational Social Science

    In this work, we compare the performance of a machine learning framework based on a support vector machine (SVM) with fastText embeddings, and a Deep Learning framework consisting on fine-tuning Large Language Models (LLMs) like Bidirectional Encoder Representations from Transformers (BERT), DistilBERT, and Twitter roBERTa Base, to automate the classification of text data to analyze the country image of Mexico in selected data sources, which is described using 18 different classes, based in International Relations theory.
